[...] U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt signed an order denying a petition that sought to ban chlorpyrifos, a pesticide crucial to U.S. agriculture.

[...] In October 2015, under the previous Administration, EPA proposed to revoke all food residue tolerances for chlorpyrifos, an active ingredient in insecticides. This proposal was issued in response to a petition from the Natural Resources Defense Council and Pesticide Action Network North America. The October 2015 proposal largely relied on certain epidemiological study outcomes, whose application is novel and uncertain, to reach its conclusions.

The public record lays out serious scientific concerns and substantive process gaps in the proposal.

EPA press release

Last month, Trump's Environmental Protection Agency administrator, Scott Pruitt, freed up the country to continue using a pesticide called chlorpyrifos on everything from strawberries and almonds to Brussels sprouts and broccoli.

This despite a warning from the National Institutes of Health that chlorpyrifos can cause "adverse developmental, reproductive, neurological and immune effects" in human beings. This despite scientific studies indicating that chlorpyrifos can interfere with fetal brain development, leading to higher rates of autism and lower intelligence.

St. Louis Post-Dispatch via Arizona Daily Sun (editorial)

More than 50 farm workers were exposed to a pesticide drift [...] southwest of Bakersfield.

[...] Twelve people reported symptoms of vomiting, nausea and one person fainted.

[...] The active ingredient in the insecticide the workers were exposed is Chlorpyrifos.

[...] It has been banned for residential use for more than 15 years, but can still be used in agriculture.

Chlorpyrifos is manufactured by the AgroSciences division of Dow Chemical Company.

A total of 47 farm workers were harvesting cabbage at the time and subsequently complained of a bad odor, nausea and vomiting. One was taken to hospital with four other workers visiting doctors in the following days.

The Guardian

On Monday [15 May], the agency shelved a proposal, originally scheduled to go into effect on March 6, intended to ensure that such poisons are safely applied.

Currently, anyone who applies pesticides on the restricted-use list has to have safety training. The proposed rule would have required workers who use the pesticides to be re-trained every five years, and to "verify the identity of persons seeking certification." It also established a minimum age for applying these chemicals: 18 years old.

Citing the regulatory freeze the Trump administration issued soon after the inauguration, the EPA announced Monday [15 May] it was putting the new requirements on ice until May 22, 2018. In addition, as Environmental Working Group noted, the agency is accepting comments on the decision only until May 19, "giving the public only a few days to comment on the rule, instead of the customary 30 days."

    Maybe it will, but even with the government involved it can take decades to force companies to stop using provably deadly chemicals.

    Especially, when it's better for everyone not to ban those provably deadly chemicals. Then bans may never happen.

    Having killed millions of people in the past century, the odious dihydrogen monoxide [dhmo.org] easily meets the "provably deadly" threshold. I think you can figure out why it hasn't been banned yet.

    Your linked page says that "inhalation of DHMO, even in small quantities" can be fatal and that DHMO is used "in pesticide production and distribution". The wording suggests to me that DMHO is a so-called inert ingredient. Chlorpyfiros, however, is an active ingredient in pesticides: it kills insects by inhibiting cholinesterase. It can also inhibit cholinesterase in humans, although we're able to detoxify it.

    In multiple epidemiological studies, chlorpyrifos exposure during gestation or childhood has been linked with lower birth weight and neurological changes such as slower motor development and attention problems.

    -- https://en.wikipedia.org/wiki/Chlorpyrifos [wikipedia.org]

    What are the effects of DMHO exposure in the womb? Have there been similar incidents in which DHMO, or a pesticide containing it, was sprayed on crops and workers in a neighbouring field became ill?

      It didn't take me long to locate YouTube videos of DHMO applied [youtube.com] as insecticide. Note that the video shows a grossly negligent application of a huge amount of DHMO. That neighborhood will probably see generations of birth defects and strange illnesses just due to this one irresponsible person.

      What are the effects of DMHO exposure in the womb?

      DHMO has always been detected in the presence of birth defects and problem births. There is no other known toxin or carcinogen with this high a level of correlation.

      Have there been similar incidents in which DHMO, or a pesticide containing it, was sprayed on crops and workers in a neighbouring field became ill?

      China has DHMO toxicity problems like you wouldn't believe. Millions of workers and others have died at a time due to unplanned DHMO releases and all five [wikipedia.org] of the worst known DHMO releases have been in China, impacting agricultural workers the most.

      To be blunt, this chicken little concern over chlorpyfiros is ridiculous. DMHO is by far the most lethal chemical in the world. Nothing else comes within orders of magnitude of it. When are we going to ban the provably deadly DHMO?
