The Environmental Protection Agency (EPA) is investigating the presence of toxic chemicals in pesticides, which may be coming from their plastic containers, it said on Friday.?
The agency said in a statement that its testing showed that the chemicals, belonging to a family of substances called PFAS, were "most likely formed" by a reaction while fluorine was being put into the containers, and then "leached into the pesticide product."
The agency said it was still early in its investigation, and that it will use "all available regulatory and non-regulatory tools to determine the scope of this emerging issue."?
President Biden's initial wave of planned executive actions includes an order to reexamine one controversial, but widely used, pesticide called chlorpyrifos. The Trump administration had stepped in to keep the chemical on the market after Obama-era officials tried to ban it.
It's just one in a long list of science-related Trump administration actions that the incoming Biden team will now revisit. In a statement, Biden promised to take a close look at all policies "that were harmful to public health, damaging to the environment, unsupported by the best available science, or otherwise not in the national interest."
Farmers use chlorpyrifos to control insects on a wide variety of crops, including corn, apples, and vegetables. It is among the most toxic pesticides. Workers exposed to it can experience dizziness, headaches, and nausea. Most indoor uses of the pesticide were halted in 2001.
The impact of T on human health received worldwide attention from the general public, political and scientific communities, with the publication of Rachel Carson’s Silent Spring.1 In Silent Spring, Carson described a series of harmful effects on the environment and wildlife resulting from the use of T and other similar compounds. ifty years later the book and the issues raised remain controversial. T, which had been effectively used to eradicate malaria carrying mosquitoes, continues to be a major public health problem and effective treatment and prevention efforts are still necessary.
Lead interferes with the body’s battalion of antioxidants, damaging NA and killing neurons. Neurotransmitters, the chemical paperboys of the brain, stop delivering messages and start murdering nerve cells. Lead inhibits the brain’s development by stonewalling the process of synapse pruning, heightening the risk of learning disabilities. It also weakens the blood-brain barrier, a protective liner in your skull that blocks microscopic villains from infiltrating the brain, the result of which can lower IQs and even cause death. Lead poisoning is rarely caught in time. The heavy metal debilitates the mind so slowly that any impairment usually goes unnoticed until it’s too late.
Poisoning from pure tetraethyl lead, however, works differently. It moves quickly. Just a few teaspoons directly applied to the skin can kill. After soaking the dermis, it leaches into the brain, and, within weeks, causes symptoms similar to rabies: hallucinations, tremors, disorientation, and death. It’s not a miracle motor drug. It’s concentrated poison.
Dry cleaners did not begin using perc until the early 1980s, when, in an ironic twist, they were forced to do so by the U.S. Office of Safety and Health Administration. Prior to that time, dry cleaners had used a hydrocarbon-based product called stoddard. Though stoddard is relatively benign environmentally, it is extremely volatile and has a very low flash point. Stoddard had, in fact, been the primary culprit in a number of serious fires. Chlorine-based perchloroethylene, by contrast, is not especially volatile.
What OSHA did not realize was that perc has the unique ability to penetrate concrete. Moreover, when freed it quickly seeks the lowest point in its environment. As a result, the chemical rapidly descends through concrete floors into the soil and eventually into the groundwater. Once there, it flows wherever the groundwater flows.
Perc was found to cause cancer not long after it was introduced to the dry cleaning industry.
