Work-Related Exposure to Pollutants Increases the Risk of Developing Heart Defects in among Hispanic/Latinx Communities

(Beyond Pesticides, September 3, 2020) Occupational exposure to pollutants including, those from wood burning, pesticides, metals, and vehicle combustion, increases the risk of developing heart abnormalities among Latinx individuals, according to new research published in the Journal of the American Heart Association. Although previous research focuses on the impact of pollutants on human health from occupational or residential exposure, this study highlights the risk chemical exposure can have on communities, especially for those underrepresented in conventional occupational health studies, such as those with Hispanic or Latinx backgrounds. People of color communities are already at greater risk of exposure to environmental and health harms, such as pesticide pollution, which has been identified as environmental racism. Additionally, not only are people of color at risk of developing various, serious health issues associated with additional or cumulative pesticide exposure, they disproportionately face an elevated risk from Covid-19 as essential workers or family members of those workers. According to the researchers, ‚ÄúThe objective of this study was to assess the relationship between occupational exposure to hazardous substances and cardiac structure and function in Hispanic/Latino participants in ECHO‚ÄźSOL (Echocardiographic Study of Latinos).‚ÄĚ It is significant as it highlights the regular/routine exposure to environmental pollutants, including pollution from […]

Study Links Pyrethroid Insecticides to Cardiovascular Disease and Other Health Hazards

(Beyond Pesticides, January 10, 2020) A new study by researchers out of the University of Iowa College of Public Health, published in JAMA (the Journal of the American Medical Association) Internal Medicine, demonstrates that greater exposure to pyrethroid insecticides is associated with higher risks of death from all causes and from cardiovascular disease. These compounds can be inhaled, ingested, or absorbed through the skin; they are highly neurotoxic, and have also been linked to certain cancers, endocrine disruption, and suppression of the immune system, as well as respiratory and reproductive impacts. The researchers gathered data, for 2,116 adults aged 20 or older, from the National Health and Nutrition Examination Survey. Each of those subjects had contributed a urine sample at some point between 1999 and 2002. Urine samples reflect levels of a pyrethroid metabolite (3-phenoxybenzoic acid) present, which in turn offer information about pyrethroid exposure. The researchers followed the participants until 2015; the research analysis was performed in the summer of 2019. Data were adjusted to accommodate multiple factors (age, sex, ethnicity, socioeconomic status, diet and lifestyle, smoking status, body mass index, and urinary creatinine levels). The co-authors report that subjects with the highest levels of metabolites had a 56% […]

Cardiovascular Disease Linked to Pesticide Exposure

(Beyond Pesticides, December 17, 2018)¬†Cardiovascular disease is a major cause of poor health and mortality across the world. Much is known about congenital and behavioral contributors to the disease, yet to date, little research has focused on potential environmental factors, including the possible contribution to cardiovascular disease (CVD) of exposures to toxic chemicals in the workplace. A recent study of CVD incidence among Hispanic and Latino workers, by Catherine Bulka, PhD, et al., has evaluated associations of self-reported exposures to organic solvents, metals, and pesticides with CVD. The study was published in the journal Heart on December 11, 2018, and is first to evaluate the role of chemical exposures in the workplace in the incidence of CVD in this demographic sector. As do many scientific investigations, this one points to a need for further study of the links that emerged between such exposures and compromised cardiovascular health. In an editorial in that same issue of Heart, commenting on the study, Dr. Karin Broberg of the Karolinska Institutet in Stockholm, Sweden, noted that¬†‚Äúexposure to metals and pesticides is common worldwide, and this study highlights the need to better understand the risks that these exposures cause, and to limit exposure in the […]

Organic Milk Healthier for the Heart

(Beyond Pesticides, December 12, 2013) Milk lovers everywhere may feel a little less guilty the next time they indulge in that usually taboo glass of creamy, whole milk ‚ÄĚ‚ÄĚas long as it is organic, that is. A new study, Organic Production Enhances Milk Nutritional Quality by Shifting Fatty Acid Composition: A United States‚ÄĒWide, 18-Month Study, conducted by Charles M. Benbrook, Ph.D. ¬†and other researchers from Washington State University found that organically produced milk provides significantly more heart-healthy omega-3 fatty acids than conventionally produced milk. The study looked at 384 samples of organic and conventional milk from across the country spanning an 18-month period of time (between 2011 and 2012) and examined the breakdown of omega-6 fatty acids as compared to omega-3 fatty acids within each sample. The results show that although the total amount of fat was almost the same, the organic milk contained 62 percent more omega-3 fatty acids and 25 percent fewer omega-6s. Omega-3 fatty acids are needed for healthy blood-clotting function and brain cell development and performance, among other essential bodily functions. Studies have linked omega-3 consumption to decreased risks of heart disease and other conditions, including cancers and Alzheimer‚Äôs. Omega-6 fatty acids are also necessary and […]

Review Highlights Dangerous Health Effects of Glyphosate

(Beyond Pesticides, May 9, 2013) A review of the scientific literature of the toxic effects of glyphosate, one of the most popular weed killers in the U.S. and the active ingredient in Roundup, links the herbicide ¬†to a wide range of diseases and suggests ¬†that more research is needed. The review, conducted by a scientist at Massachusetts Institute of Technology (MIT), looks at the mechanisms through which the adverse effects may be happening and points to ¬†the chemical‚Äôs inhibition of cytochrome P450 (CYP) enzymes, which plays the crucial role of detoxifying xenobiotics. Thus, glyphosate can enhance the negative effects of other environmental toxicants on the body. Authors argue that this has been a critically overlooked component in research on glyphosates‚Äô toxicity to mammals. We “have hit upon something very important that needs to be taken seriously and further investigated,” Stephanie Seneff, PhD, lead author and research scientist at MIT, told Reuters. Not surprisingly, Monsanto, the developer of Roundup, the leading product containing glyphosate, has attempted to discredit the study, claiming that its product has a long track record of being safe – read Another Bogus “Study.” However, Beyond Pesticides has assembled ¬†extensive documentation on the human health and environmental risks […]

New Research Links Pesticides to Cardiovascular Disease

(Beyond Pesticides, October 14, 2011) Researchers at Uppsala University in Sweden have found that environmental toxicants such as dioxins, PCBs, and pesticides can pose a risk for cardiovascular disease. The results of the study, entitled ‚ÄúCirculating Levels of Persistent Organic Pollutants (POPs) and Carotid Atherosclerosis in the Elderly,‚ÄĚ show a link between exposure to persistent organic pollutants (POPs), including several organochlorine pesticides, and the development of atherosclerosis, which can lead to heart disease. The study will be published in the journal Environmental Health Perspectives, and a version of it is available online ahead of print. Cardiovascular diseases, including heart attacks and strokes, are the most common cause of death in industrialized countries, and the most important underlying cause of these diseases is atherosclerosis. Unbalanced blood fats, diabetes, smoking, and high blood pressure are traditionally recognized risk factors for atherosclerosis. Previous studies have also reported possible links between cardiovascular disease and high levels of persistent (long-lived and hard-to-degrade) organic environmental toxicants, such as dioxins, polychlorinated biphenyls (PCBs), and pesticides. These compounds are fat-soluble and can therefore accumulate in vessel walls. However, no earlier studies have investigated possible links between exposure to these compounds and atherosclerosis. Of the POPs that were screened […]
