(Beyond Pesticides, June 16, 2015) France’s Ecology Minister Segolene Royal announced Sunday a  call to  stop  the sale of the popular Monsanto herbicide Roundup (glyphosate) from garden centers. The announcement comes just a couple of  months after the active ingredient, glyphosate, was classified in March as “probably carcinogenic to humans” by the United Nation’s International Agency for Research on Cancer (IARC). “France must be on the offensive with regards to the banning of pesticides,” Royal said on French television. “I have asked garden centers to stop putting Monsanto’s Roundup on sale” in self-service aisles, she added. The announcement comes after a request by French consumer association CLCV (Consumption, Housing and Environment – Consommation, Logement et Cadre de vie)  to French and European officials to stop selling glyphosate-based products to amateur gardeners. Royal also announced last week that from January 2018 onwards, phytosanitary products —used to control plant diseases— would only be available to amateur gardeners “through an intermediary or a certified vendor.” Glyphosate is touted as a “low toxicity” chemical and “safer” than other chemicals by EPA and industry and is widely used in food production and on lawns, gardens, parks, and children’s playing fields. However, IARC’s new classification of […]

(Beyond Pesticides, May 14, 2015) For the first time on record, summer losses of managed honey bee colonies have exceeded winter losses, according to preliminary results of the annual survey released yesterday by the Bee Informed Partnership, the U.S. Department of Agriculture (USDA) and the Apiary Inspectors of America. This is the second highest annual loss recorded to date: beekeepers lost a total of 42.1 percent of the number of colonies managed over the last year (total annual loss, between April 2014 and April 2015), which is up from 34.2 percent for the previous year. On the same day that this survey was released, the  U.S.  House Agriculture Subcommittee on Horticulture, Biotechnology and Research held a hearing on pollinator health, but failed to advance policy solutions that would protect pollinators from the unnecessary use of pesticides. “What we’re seeing with this bee problem is just a loud signal that there’s some bad things happening with our agro-ecosystems,” Keith Delaplane, PhD at the University of Georgia and one of the co-authors of the study told Phys.Org. “We just happen to notice it with the honeybee because they are so easy to count.” About two-thirds of the beekeepers responding to the survey […]

(Beyond Pesticides, April 21, 2015) Last week, Health Canada opened public comments on its reevaluation decision for glyphosate, the active ingredient in Monsanto’s Roundup herbicide. The agency chose to continue allowance of the herbicide, but include some changes to the label of glyphosate-containing products. The decision comes shortly after the International Agency for Research on Cancer determined that the chemical is a human carcinogen based on laboratory animal test data,  and a recent study revealed that glyphosate accelerates antibiotic resistance. Health Canada’s label changes include the following: A requirement for a statement indicating to apply only when the potential for drift to residential or populated areas is minimal. This includes houses, cottages, schools and recreational areas A restricted entry interval (REI) of 12 hours for agricultural uses to better protect agricultural workers; New environmental hazard statements to inform users that, at high enough doses, it can be toxic to non-target species; Recommended spray buffer zones to protect non-target terrestrial and aquatic habitats from unintended exposure; and, Precautionary statements to reduce the potential for run off of glyphosate to adjacent aquatic habitats, particularly when heavy rain is forecasted. This includes a recommendation to keep a strip of vegetation between the treatment […]

(Beyond Pesticides, April 7, 2015) Scientists working with the United States Department of Agriculture (USDA) don’t have adequate protections from pressure and retaliation when researching issues that threaten the interests of powerful agrichemical corporations like Monsanto, according to Public Employees for Environmental Responsibility (PEER), which filed a petition for rule-making with the agency last month. PEER’s petition seeks to strengthen USDA’s Scientific Integrity Policy, and urges the agency to adopt best practices used in other federal agencies in order to prevent political suppression or alteration of studies. USDA adopted a new integrity policy in 2013 in response to a 2009 memorandum issued by President Obama with the goal of “ensuring the highest level of integrity in all aspects of the executive branch’s involvement with scientific and technological processes.” PEER alleges that USDA’s policy falls far short of this aim, even containing language which actively encourages the agency to suppress scientific work for political purposes. USDA’s current policy reads, “scientists should refrain from making statements that could be construed as being judgments of or recommendations on USDA or any other federal government policy, either intentionally or inadvertently.” PEER explains that USDA management regularly uses this provision as reason for suppressing technical […]

(Beyond Pesticides, March 16, 2015) Last week, a judge in Duesseldorf Regional Court ruled that the German branch of Friends of the Earth (BUND) has a right to speak out against chemical company giant Bayer CropScience’s neonicotinoid pesticide, thiacloprid, regarding its potential danger to bees. The court considered the allegations put forth by BUND to be a form of free speech, a protected right. Neonicotinoids, a class of insecticides, affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sub-lethal exposure causing changes in bee reproduction, navigation and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees. Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites and other diseases, leading to devastating bee losses. Thiacloprid is one of the seven most commonly used neonicotinoids. It is used to control sucking and biting insects in cotton, rice, vegetables, pome fruit, sugar beet, potatoes and ornamentals. Low doses of neonicotinoids are considered highly […]

(Beyond Pesticides, February 23, 2015) A Hawaii state House agriculture committee rejected a bill Thursday that sought to impose buffer zones for large agricultural companies that spray restricted-use pesticides near schools and other sensitive areas. The proposal, House Bill 1514, introduced by Rep. Chris Lea, stemmed from concerns about  the impact of genetically-engineered (GE) farming and its inherent dependency on increasing  pesticide use. The measure sought  to require companies’  disclosure of the pesticides used and the volume of use. The bill had strong support from the Hawaii chapter of the national nonprofit Center for Food Safety (CFS), as well as a strong backing from neighbor island residents. Maui, Kauai, and the Big Island have all passed laws recently to regulate the seed industry, but a federal  district  court judge  has ruled  that Hawaii counties do not have that power. Industry has been especially effective in obstructing the bill. CFS’ Hawaii director, Ashley Lukens, said after Thursday’s hearing that she was frustrated by the limited amount of time advocates were given to testify. “It was clear from the very beginning that the hearing was intended to allow the industry to reiterate their talking points,” she said. Not surprisingly, companies (like Monsanto) […]

(February 9, 2015, Beyond Pesticides) A report, Monarchs in Peril: Herbicide-Resistant Crops and the Decline of Monarch Butterflies in North America, released by Center for Food Safety (CFS) last week, reveals the devastating  impact of Monsanto’s and the nation’s biggest selling herbicide, Roundup (glyphosate), on the survival  of monarch butterflies. The herbicide is  used to treat  millions of acres of herbicide-tolerant  genetically engineered (GE) crops, eliminating the monarchs’ sole source  of food, milkweed, and approaching  a collapse of their population, which has plummeted over the past 20  years. The report cites findings that  glyphosate use on Roundup Ready  (glyphosate-tolerant) crops has nearly eradicated milkweed around farmland in the monarchs’ vital midwest breeding ground. At the urging of scientists and public interest groups, the U.S. Fish and Wildlife Service (FWS) is currently considering listing the monarch as a threatened species under the Endangered Species Act (ESA). “This report is a wake-up call. This iconic species is on the verge of extinction because of Monsanto’s Roundup Ready crop system,” said Andrew Kimbrell, executive director at Center for Food Safety. “To let the monarch butterfly die out in order to allow Monsanto to sell its signature herbicide for a few more years is […]

(Beyond Pesticides, February 4, 2015)    In the face of a challenge from the chemical industry, Hawaii’s Maui County will not defend a moratorium on genetically engineered (GE) farming that was passed by county voters last fall. Seeking to have the moratorium thrown out, industry giants Monsanto, Dow-owned Agrigenetics and others sued Maui days after the measure was passed.   It was expected that the county would defend the law in the courts, but to the disappointment of many, attorneys for Maui County filed a single sentence brief with the court, stating that it “is taking no position.” In November 2014, Maui residents passed a ballot initiative prohibiting the growth, testing or cultivation of GE crops in Maui County until an environmental and public health study can show that the planting operations are safe for the community. Now residents and local groups supporting the new law are expressing outrage and disappointment over the decision by Maui County to disregard its duty to defend a law passed by its citizens, despite earlier assurances that county will implement the moratorium. Maui County spokesman Rod Antone said that the outrage from activists groups is misplaced. In December, the court allowed the local group, […]

(Beyond Pesticides, January 15, 2015) Yesterday, the European Union (EU) passed legislation meant to bridge a long-standing divide amongst EU nations (and the United States) on the planting of genetically-engineered (GE) crops by granting individual countries the authority to opt-out of EU crop approval and institute country-based legislative and regulatory restrictions. Makers of GE crops (like Monsanto) and proponents of GE crop cultivation have faced staunch and successful opposition in getting the required EU permission to plant GE crops. Opposition comes from both EU citizens and certain member states, like France, Italy, and Germany. By giving opposing countries an EU-sanctioned means to opt-out and establish individual member state restrictions, the new law may accelerate  opt-outs in those countries that do not oppose GE crop planting. Countries like France that have repeatedly fought back against GE crop cultivation welcome the new EU legislation, as do environmental advocates. “This is another nail in the coffin of genetically modified crops,” said Mute Schimpf, a campaigner for Friends of the Earth Europe, told Bloomberg. “While not perfect, this new law allows governments to shut the door on biotech crops in Europe.” Countries in favor of GE crop cultivation, like Britain, also view the action […]

(Beyond Pesticides, January 13, 2015) Over a decade after consumer opposition halted multinational agrichemical business Monsanto’s plans to develop genetically engineered (GE) herbicide-resistant wheat, the company is trying again. This time, Monsanto’s goal is to create wheat that is resistant to three different herbicides; glyphosate, glufosinate, and dicamba. Although over 90% of corn, soybean, and cotton grown in the United States are GE, no GE wheat is currently allowed to be planted. In 2013, a farmer in Oregon discovered the presence of Monsanto’s original Roundup-Ready wheat, developed to be resistant to glyphosate, in his field despite the company’s plans to abandon the strain and claims to have destroyed the crop  a decade earlier. The company had restarted extensive field trials back in 2011. An investigation by the U.S. Department of Agriculture (USDA) determined that the contamination was an “isolated incident.” It was unable to determine exactly how the wheat came to grow in the Oregon farmer’s field. However, shortly after the agency closed its investigation, another farmer in Montana detected the GE strain in his wheat fields. The recurrence of this incident reveals the contamination event not to be an isolated incident. It instead demonstrates the threat that these crops […]

(Beyond Pesticides, December 17, 2014)   Supporters of an Oregon ballot initiative requiring labels on genetically-engineered (GE) food acknowledged defeat last Thursday after an automatic recount failed to change the results of November’s vote and a judge denied their plea for a count of rejected ballots. Advocates expressed deep disappointment that a Monsanto led multi-million dollar opposition campaign narrowly defeated the Oregon ballot initiative even after an emergency lawsuit was filed to prevent the rejection of over 4,000 votes due to non-fraudulent discrepancies. Measure 92 lost by a narrow margin in November elections, triggering a recount and making it the closest statewide election in Oregon history. Measure 92 would have required manufacturers, retailers, and suppliers to clearly label all genetically-engineered foods or ingredients in raw or packaged items. It was defeated by only 812 votes out of 1.5 million. The automatic recount is pursuant to Oregon voting law, but the new tally showed that the measure lost by just 0.056 percent. On December 8, 2014, an emergency lawsuit was filed by the Yes on 92 Campaign in order to prevent over 4,000 votes from being thrown out by state officials due to non-fraudulent discrepancies in voter signatures.   The judge […]

(Beyond Pesticides, November 20, 2014) A study published in the Journal of Organic Systems this week examined potential connections between the increase in chronic diseases seen within the United States and other parts of the world over the last 20 years and the explosion of glyphosate use, finding a significant correlation between glyphosate use, genetically-engineered (GE) crops, and human health. Glyphosate, one of the most popular weedkillers in both the U.S. and the world, is the active ingredient in Roundup ® ””the leading glyphosate product developed by Monsanto. Known as “Roundup Ready,” GE soybeans, corn, cotton, and other crops have been genetically altered and patented by Monsanto to be glyphosate-tolerant. Whether a crop stems from a Roundup Ready seed or not, glyphosate is used in almost all agricultural areas of the U.S., as well as on an international scale, in conventional, non-organic farming operations. Because of Roundup’s popularity, glyphosate use has skyrocketed, leading to an estimated application of nearly 250 million pounds of the chemical across the U.S. alone and resulting in significant problems of glyphosate resistance and the increased presence of the herbicide in our food and environment. The increased presence of glyphosate has also ushered in independent data […]

(Beyond Pesticides, November 17, 2014) In anticipation of the lawsuit by agrichemical giants following a newly passed initiative to suspend the planting of genetically engineered (GE) crops in Maui, five residents preemptively filed a lawsuit last Wednesday, November 12 beating their opponents by one day. The moratorium is only a temporary measure that bans GE crops until the county analyzes the public health and environmental effects, and it is deemed safe. Yet, despite this Monsanto, along with Dow AgroSciences, the Maui Farm Bureau and other businesses filed their own lawsuit against the county Thursday, November 13 saying that  the “referendum is invalid and contrary to long established state and federal laws that support both the safety and lawful testing and planting of GMO plants.” Maui County residents Dr. Lorrin Pang, Mark Sheehan, Lei’ohu Ryder, Bonnie Marsh and Alika Atay, along with the Shaka Movement, filed their lawsuit in the Second Circuit court in Hawaii against the county, Monsanto and Dow AgroSciences. The lawsuit seeks to assure transparency and influence over the implementation of the initiative, in light of the enormous amount of money that the ag companies have poured into the county in an attempt to beat the initiative. According […]

(Beyond Pesticides, November 10, 2014) According to a new Government Accountability (GAO) report, the U.S. Food and Drug Administration (FDA) does not test food for several commonly used pesticides with established tolerance levels —including glyphosate, one of the most commonly used pesticides in the U.S. This and other disturbing findings documented in GAO’s report,  Food Safety: FDA and USDA Should Strengthen Pesticide Residue Monitoring Programs and Further Disclose Monitoring Limitations,  issued last Thursday, sounds an alarm that GAO began sounding  in the 1980’s in several reports that identify shocking limitations of  FDA’s approach to monitoring for pesticide residue violations in food. GAO sharply criticizes FDA for not using statistically valid methods consistent with Office of Management and Budget (OMB) standards to collect information on the incidence and level of pesticide residues. In fact, GAO states that it “was unable to find publicly available estimates of the overall toxicity or risk associated with the use of agricultural pesticides in the United States.” According to GAO, FDA is testing less than one-tenth of one  percent of all imported fruits and vegetables and less than 1 percent of domestic fruits and vegetables.  The report is also critical of U.S. Department of Agriculture’s (USDA) […]

(Beyond Pesticides, October 1, 2014) Just after announcing a close to its investigation into the illegal presence of genetically engineered (GE) wheat in Oregon, finding it to be an “isolated  incident,”  the U.S. Department of Agriculture (USDA) opened a new investigation into another incident of unauthorized release of  GE wheat, this time  detected in Montana. This new report highlights the contamination threat that these materials pose to farmers and the environment, as well as the government’s failure to recognize the pervasive and persistent nature of GE contamination. According to USDA, on July 14, 2014 it was notified that suspected GE wheat had been discovered growing at the Montana State University’s Southern Agricultural Research Center (SARC) in Huntley, Montana, where Monsanto and researchers grew GE wheat as part of field trials between 2000 and 2003. Testing of the samples by a USDA laboratory confirmed that the wheat is genetically engineered to resist Roundup. The agency states that its ongoing investigation is focusing on why GE wheat was found growing at the research facility location. Currently, GE wheat has not been deregulated by USDA, unlike several other GE crops (corn, soybean, sugarbeets). This means that any experimental use of GE wheat must […]

(Beyond Pesticides, September 19, 2014) The pesticide treadmill continues to turn with the U.S. Department of Agriculture’s (USDA) recent approval this week of three 2,4-D-tolerto ant corn and soybean crops, developed by Dow AgroSciences. Some growers have been pushing for the new Enlist crops in order to combat the rapid proliferation of glyphosate-resistant weeds. The use of glyphosate, the active ingredient in Monsanto’s Roundup formulation, on genetically-engineered (GE) crops has proven to be an abject failure due to widespread weed resistance. So widespread is this resistance that the U.S. Environmental Protection Agency (EPA) has  granted an emergency use exemption  for fluridone, which does not have registered uses in agriculture.  More recently, Texas regulators requested the use of propazine to combat glyphosate-resistant Palmer amaranth, or pigweed, which EPA recently denied,  citing risks to drinking water and other hazards.   Even though the agency denied the emergency use application, it accepted the argument put forth by the Texas Department of Agriculture that  glyphosate-resistant weeds in three million acres of herbicide-tolerant cotton constituted an  “urgent non-routine situation.”  Beyond Pesticides argued to EPA that the weed resistance in  herbicide-tolerant cropping systems is very predictable and has become routine, thus disqualifying states from using the […]

(Beyond Pesticides, August 8, 2014) Despite the continued documentation of weed resistance all over the United States, as well as the world, another line of herbicide-tolerant crops developed by Monsanto is currently in the pipeline awaiting likely approval by U.S. regulators. The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) released a draft environmental impact statement (EIS) on Tuesday, which, according to regulators, will pave the way for the approval of new  genetically modified cotton and soybean plants tolerant to a mixture of the herbicides glyphosate and dicamba. Monsanto’s new soybean and cotton crops were developed to withstand their new herbicide formulation, called Roundup Xtend, which combines the pesticides dicamba and glyphosate. The “Roundup Ready Xtend crop system” was developed to curb the proliferation of millions of acres of weeds that have grown resistant to Monsanto’s glyphosate-based Roundup, which has been used on the company’s biotech corn, soybeans, and cotton. Weed resistance due to cropping systems dependent on herbicides has been documented for years, making APHIS’ conclusions in the EIS all the more alarming. A report that Beyond Pesticides published 12 years ago, “The Environmental Risks of Transgenic Crops: An Agroecological Assessment is the failed pesticide […]

Beyond Pesticides, May 30, 2014) This week, a group of concerned mothers and environmentalists met with U.S. Environmental Protection Agency (EPA) officials  to discuss a recent pilot study that detected glyphosate residues in breast milk. Organized by Mom’s Across of America, which is seeking to stop the sale and use of glyphosate, the meeting  underscored the limitations of EPA’s pesticide registration program in addressing  the real-life impacts of pesticides on children and the concerns of mothers surrounding the dangers of glyphosate in particular.  Glyphosate, the active ingredient in the herbicide Roundup, is the most widely applied herbicide in the U.S., with uses ranging from genetically engineered (GE) crops to lawn turf. The meeting with Moms Across America, Beyond Pesticides, Consumes Union, Organic Consumers Association,  other groups  and EPA came after Mom’s Across America’s five-day phone call campaign urging EPA to recall Roundup. Participants in the campaign made close to 10,000 calls to the agency. The pilot study, supported by Moms Across America, looked at ten breast-milk samples from across America. Three of the ten breast milk samples tests reveal high levels of glyphosate, meaning that the amount of glyphosate found is between 76 ug/l to 166 ug/l. The highest glyphosate […]

(Beyond Pesticides, May 23, 2014) Residents in two Oregon counties, Jackson and Josephine, voted to ban the cultivation, production, and distribution of genetically engineered (GE) crops within the counties’ borders Tuesday.  The Jackson County measure 15-119, passed with 66 percent of the vote, while Josephine County passed with 58 percent. As noted by Reuters, the newly approved measures mandate that people “harvest, destroy or remove all genetically engineered plants” no later than 12 months after the ordinances go into effect. This is great news for farmers of organic and non-genetically engineered crops, who constantly struggle with the threat of GE contamination. Though there are less than 120,000 registered voters in Jackson County, the measure gained national attention due to the fact that opponents raised over $830,000 to advertise againstthe measure, with over 97% of the funding coming in from outside of the county, including over $450,000 from biotech giant Monsanto and five other corporations to defeat the initiative. For comparison, the previous county spending record on a ballot initiative was $111,000. “We fought the most powerful and influential chemical companies in the world and we won,” Elise Higley, a Jackson County farmer and representative from  Our Family Farms Coalition told […]

(Beyond Pesticides, May 20, 2014) Pittsburgh sportscaster Rich Walsh is suing multinational chemical companies after his father’s untimely death from cancer in 2009. According to a story from local Pittsburgh station WTAE, Mr. Walsh’s father, Tom Walsh, was diagnosed with acute myeloid leukemia in 2008, after a career as a golf course superintendent. “He loved golf. He loved working outside. He loved to take care of golf courses,” Rich told WTAE. Rich’s lawsuit was filed against Monsanto, Bayer CropScience, BASF, Syngenta, Dow Agroscience, Deere and Company, and John Deere Landscapes in 2010. Genetic testing from Tom’s oncologist showed chromosomal alterations as a result of years of working with pesticides, the only chemicals Mr. Walsh ever worked with. Part of the log books he kept throughout his career included the pesticides he applied, which included the insecticides Dylox and Dursban, active ingredients trichlorfon and chlorpyrifos respectively, and the fungicides Daconil and Chipco, active ingredients chlorothalonil and iprodione. All of these chemicals have been shown to be likely carcinogens, according to Beyond Pesticides’ Pesticide Gateway or Pesticide Induced Diseases Database. Chlorpyrifos, for instance, was banned for homeowner use back in  2001, but uses on agriculture and golf courses were allowed to continue […]

(Beyond Pesticides, April 30, 2014) A new report, released this week by author  Michele Simon  and Friends of the Earth  documents the tactics used by Bayer and other pesticide companies to delay regulatory action on neonicotinoid pesticides —a key contributor to bee declines. The report identifies public relations tactics reminiscent of those used by the tobacco industry, is now being used by Bayer, Syngenta, and Monsanto. Meanwhile, a Congressional hearing on pollinator health, with a panel dominated by industry, ignored the risks pesticides pose to pollinators, and failed to address sustainable solutions to bee decline. The report,  Follow the Honey: 7 Ways Pesticide Companies Are Spinning the Bee Crisis to Protect Profits,  uncovers the deceptive public relations tactics used by industry giants Bayer, Syngenta and Monsanto, to deflect blame from their products’ contributions to bee declines. The products in question are the chemicals now widely used for seed treatment  —neonicotinoids— as well as on residential sites. They are highly toxic to bees and have been linked to bee decline. Last year, the European Union banned the three most widely used neonicotinoids —imidacloprid, clothianidin and thiamethoxam— based on strong science indicating these insecticides can kill bees outright and make them more […]

(Beyond Pesticides, April 24, 2014) France’s lower house of parliament passed a bill last week banning the cultivation of all strains of genetically engineered (GE) corn within its borders, even those strains that might not yet be approved within the European Union (EU). The law follows a decree adopted last month, which targeted the only GE crop permitted for cultivation in the EU””Monsanto’s insect-resistant MON810 corn. Back in the U.S., Vermont became the first state to pass a  bill requiring the labeling of food containing GE ingredients  (You can read the House bill as it was introduced here and the Senate amendments to this bill here). The bill, which the Governor said he will sign, passed by large majorities in both houses of the legislature and does not contain a trigger provision similar to laws adopted in Connecticut and Maine  –with a  requirement that  similar action is taken in contiguous states before the law goes into effect. The action in France is not  the first time it has closed the door on MON810, even in the face of its highest court’s rulings that similar bans did not have sufficient justification. Yet, undaunted by these defeats the French General Assembly went […]

(Beyond Pesticides, April 14, 2014) Bowing to political pressure and agrochemical industry opposition Sri Lanka’s government has taken a step back from its original decision to place a ban on one of the most widely used herbicides worldwide ””glyphosate. Scientific evidence has tied glyphosate to the incurable, deadly kidney disease that has afflicted thousands of Sri Lankans. The delay marks a setback in efforts by scientists and activists to remove from the shelves  a chemical widely used on tea and rice paddy plantations in Sri Lanka.   The decision to ban the chemical was initiated following the publication of a scientific report demonstrating that kidney disease was primarily caused by glyphosate. The report provides a summary of existing scientific information demonstrating kidney failure among farmers who were exposed to the popular herbicide. Indeed lead author Channa Jayasumana, PhD. explains that glyphosate bonds with toxic heavy metals in the environment such as cadmium and arsenic, forming stable compounds that are consumed in food and water and do not break down until they reach the kidneys. “Glyphosate acts as a carrier or a vector of these heavy metals to the kidney,” said Dr. Jayasumana. The chemical was initially created as a chelating […]
