Malathion, one of the two chemicals sprayed along roads in the BLSG District to kill mosquitoes, is an organophosphate pesticide. A new peer-reviewed study, published yesterday, concludes that organophosphate pesticide exposure in pregnant women can be responsible for a significant drop in IQ of their children. According to the study, in recent years, organophosphate pesticides and flame retardants have overtaken lead and mercury as the chemicals responsible for the biggest loss of IQ among children. The abstract of the study in Molecular and Cellular Endocrinology is here and a news article about the study is here.Continue reading “New study links organophosphate pesticides to IQ loss”
Last month an article about the health effects of pyrethroid insecticides was published by the Journal of the American Medical Association (JAMA Internal Medicine). You can read a summary here and a news article here. The peer reviewed article describes the results of a study of 2116 nationally representative American adults who were followed for 17 years. At the beginning of the study each participant had a urine test for pyrethroids. During the study 246 of the participants died, and those with higher levels of pyrethroids at the start of the study were more likely to die. The group was divided into thirds (low, medium, and high levels of pyrethroids), and those in the high group were three times more likely to die from cardiovascular disease than those in the low group. Those in the high group were 1.5 times more likely to die of any cause compared to the low group.Continue reading “New long-term study links pyrethroids and health risk”
Last week a new scientific article was published about the relationship between pesticides and autism spectrum disorder in California. The study confirmed that prenatal or infant exposure to pesticides, including malathion and permethrin, increased the likelihood of developing autism spectrum disorder in childhood. Malathion and permethrin are the two pesticides sprayed along roads to kill adult mosquitoes in the BLSG Insect Control District. The article was published in the BMJ, a peer-reviewed journal of the British Medical Association.
There is a lot of information available about the pesticides used in the BLSG Insect Control District. The most recent public notice from the District identifies the pesticides as “malathion or synthetic pyrethroid insecticides.” On the EPA’s mosquito control website, the page about malathion suggests that “people who are especially concerned may choose to take some of these steps to help reduce exposure”:
