(Beyond Pesticides, February 1, 2024) A study published in Science of The Total Environment finds an insecticide ban would be economically beneficial in preventing Parkinson’s disease (PD). Despite differing pesticide exposure scenarios, PD risk lowers without pesticide exposure, especially insecticides that elicit neurotoxicity. In fact, a study published in 2023 notes high exposure to household pesticides, which are primarily insecticides, increases the risk of developing Parkinson’s disease (PD) two-fold. There is a multitude of epidemiologic research on Parkinson’s disease demonstrating several risk factors, including specific genetic mutations and external/environmental triggers (e.g., pesticide use, pollutant exposure, etc.). However, several studies find exposure to chemical toxicants, like pesticides, has neurotoxic effects or exacerbates preexisting chemical damage to the nervous system. Studies suggest neurological damage from oxidative stress, cell dysfunction, and synapse impairment, among others, can increase the incidence of PD following pesticide exposure. Despite the widespread commercialized use of household pesticides among the general population, few epidemiologic studies examine the influence household pesticides, mainly insecticides or disinfectants, have on the risk of PD. Additionally, many studies demonstrate the association between PD onset and occupational (work-related) pesticide exposure patterns. Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans […]

(Beyond Pesticides, May 23 2023) New research is zeroing in on the role of 10 commonly used pesticides in the development of Parkinson’s. Published in the journal Nature Communications by a team of scientists lead by researchers at the University of California, Los Angeles, the study focused on the toxicity of these pesticides to neurons that have been found to lead to the presentation of the disease. Research is increasingly focusing on environmental exposures, and pesticides in particular, as a major factor in the development of Parkinson’s. This study adds further evidence that this line of research is a valid and worthwhile undertaking for the nearly one million people in the United States struggling with this incurable disease. [The authors note that the herbicide paraquat’s strong connection to Parkinson’s is not addressed in this study, but is the focus of a separate manuscript.] Scientists sought to further focus on which pesticides were most likely to be playing a role in Parkinson’s development. Records from California’s vast pesticide use database aided the search. From a comprehensive pesticide-wide association study, 53 of 288 pesticides screened were found to be linked to Parkinson’s. Scientists then took these 53 pesticides and conducted live-cell imaging […]

(Beyond Pesticides, July 20, 2020) Does your community spray toxic pesticides for mosquitoes? In a well-intentioned but ill-informed attempt to prevent mosquito-borne illness such as West Nile virus, many communities spray insecticides (adulticides) designed to kill flying mosquitoes. If your community is one of these, then your public officials need to know that there is a better, more-effective, way to prevent mosquito breeding. Tell your public officials to stop spraying pesticides and adopt a mosquito management plan that protects public health and the environment. The problem with mosquito pesticides. Two classes of insecticides are favored by mosquito spray programs—organophosphates and synthetic pyrethroids. In order to better target flying mosquitoes, adulticides are generally applied as ultra-low-volume (ULV) formulations that will float in the air longer than usual. Pesticides are toxic chemicals and can exacerbate respiratory illnesses like Covid-19.Organophosphates, which include malathion (Fyfanon), naled (Dibrom), and chlorpyrifos (Mosquitomist for public health uses only) are highly toxic pesticides that affect the central nervous, cardiovascular, and respiratory systems. Symptoms of poisoning in humans include numbness, tingling sensations, headache, dizziness, tremors, nausea, abdominal cramps, sweating, incoordination, blurred vision, difficulty breathing, slow heartbeat, loss of consciousness, incontinence, convulsions, and death. Some organophosphates have been linked to […]

(Beyond Pesticides, November 21, 2018) A study published last month in the Journal of Apicultural Research finds significant numbers of U.S. honey bees at risk after exposure to hazardous synthetic pesticides intended to control mosquitoes. With many beekeepers rarely given warning of insecticide spraying, researchers say the risk of losing colonies could increase. Advocates say fear of Zika and other mosquito-borne illnesses could result in counterproductive and reactionary insecticide spraying that will add further stress to managed and native pollinators already undergoing significant declines. Researchers aimed to determine whether neighboring honey bee colonies could be similarly affected by aerial insecticide spraying. To calculate the percentage of colonies that could be affected, density of honey bee colonies by county was compared with projections of conditions thought to be prone to regional Zika virus outbreaks. Researchers found 13 percent of U.S. beekeepers at risk of losing colonies from Zika spraying. In addition, it was determined that many regions of the U.S. best suited for beekeeping are also those with favorable conditions for Zika-prone mosquitoes to proliferate. These regions include the southeast, the Gulf Coast, and California’s Central Valley. “[Considering] all the threats facing bees,” says study lead author Lewis Bartlett of the […]

(Beyond Pesticides, July 11, 2017) South Florida resident Michael Hall, M.D., filed an emergency request in federal court last week to block Miami-Dade County’s continued use of the organophosphate insecticide naled to control mosquito populations. There have been two rounds of aerial naled applications in Miami-Dade this year. Widespread use of the chemical in efforts to control the transmission of Zika last year prompted protests from residents complaining of health effects from the spraying, and calls to focus on less toxic, alternative methods of mosquito breeding prevention and control. The present use of naled in Miami-Dade is not focused on Zika control, but addressing the native salt marsh mosquito, which does not transmit human diseases, but can be a significant nuisance in shoreline areas. According to WLRN, officials are no longer using naled for Zika control as the mosquito species that carries it, Aedes aegypti, usually stays well hidden under vegetation and shrubbery. A study released last year confirmed that the county’s use of naled did little to reduce mosquito populations. “Naled, a potent organophosphate adulticide applied aerially, produced a transitory suppression in Wynwood but lost efficacy after two or three applications. In Miami Beach, aerial application of naled produced […]

(Beyond Pesticides, June 13, 2017) Prenatal exposure to commonly used mosquito and agricultural insecticides is associated with decreased motor function in infants, according to a study published in Environment International by a team of Chinese and U.S. researchers. The results of the study should give pause to insecticide-heavy efforts to control mosquitoes as the season ramps up this summer and fall. Frequent spraying as part of efforts to control Zika in Southern Florida last year resulted in large protests and calls for a preventive management approach not dependent on toxic chemicals. For the current study, over 350 pregnant Chinese mothers were tested for the presence of organophosphate pesticides in their umbilical cord blood. Researchers looked at exposure to the insecticides naled, methamidophos, trichlorfon, chlorpyrifos, and phorate. After giving birth, their children’s motor function was tested at both six and nine months of age. Tests included an analysis of the infant’s reflexes, locomotion, grasping, stationary and visual-motor integration abilities. Scores were categorized based on gross, fine, and total motor skills, and standardized quotients were created for each of the categories. Of the over 300 mothers, roughly 240 had detectable levels of one of the insecticides in their samples. Although no differences […]

(Beyond Pesticides, February 1, 2017) Last week in North Miami, the City Council took a significant step that could reduce pesticide use in the community. The Council adopted an Integrated Pest Management (IPM) policy modeled after a plan developed by San Francisco in the mid-90’s. The plan does not ban pesticides and herbicides, but instead aims to reeducate citizens and county workers on least-toxic pest management strategies with the goal of eliminating toxic pesticide use on city property.  The IPM plan does not address pesticide use on private property, due to state preemption of local authority. With the passage of the North Miami’s resolution, city operatives will now be asked to give preference to available, safe and effective non-pesticide alternatives and cultural practices. As stated in the resolution’s Integrated Pesticide Management Program Guidelines, the goal of the policy is “to eliminate the application of all Toxicity Category I and Category II pesticide products by January 2018.” On top of eliminating certain pesticide categories, the resolution also calls for staff training and expert consultants, both of which have the potential to help ease the transition in pursuit of the 2018 goal, and priority will be given to efforts to reduce or eliminate pesticide use near […]
