US EPA still ignoring the problem of ‘chemical cocktails’


Natural Health News – The Agency of Environmental Protection has approved almost 100 pesticide products during the past six years containing mixtures that make them more poisonous and increase the dangers for pollinators endangered and rare plants.

According to an investigation by the Center for Biological Diversity, these combinations “synergistic” have been largely dominated by EPA approval of pesticides for food, lawn and other uses.

The new report by the Center Toxic Concoctions: How the EPA ignored the dangers of cocktails of pesticides , involved an intensive search of patent applications for pesticide products containing two or more recently approved by the EPA active ingredients for the four major agrochemical companies :. Bayer, Dow, Monsanto and Syngenta

“The EPA is supposed to police on the street, protecting people and the environment from the dangers of pesticides,” said Nathan Donley, a scientist Center and author of the report. “With these synergetic pesticides, EPA has decided to look away, and I guess it has failed to pay the price?”

What you need to know

The Environmental Protection Agency US has approved almost 100 pesticide products in the last six years containing “synergistic” mixtures of chemicals that make them more toxic to humans, plants and insects.

safety information presented to regulators by large chemical companies often minimizes the effect of synergy. However patent applications do not include this information, as they must demonstrate how the product works.

the EPA recently used information from the patent application to try to remove is the approval of a pesticide product called enlist Duo.

The request was denied, but according to activists, patent applications – which are public records -. They are a useful tool, if overlooked, source of information on the toxicity

Synergy occurs when two or more chemicals interact to improve their toxic effects. You can turn what is normally considered a safe level of exposure one resulting in considerable damage. mixtures of pesticides are ubiquitous in the environment and is also present in many products for sale in stores.

At the end of 2015, in preparation to defend against litigation registration of a pesticide product called Enlist Duo, the EPA discovered a new source of information about the product: the Patent and Trademark EE .S. Database of the Office, which contained a patent application indicating the two ingredients of this product, glyphosate and 2,4-D, as a result of synergistic toxicity to plants.

This discovery ultimately led the agency to ask the Circuit Court of Appeals for the 9th to vacate its approval of the Enlist Duo, since it had not adequately considered the potential adverse effects of this synergy in nontarget plants .

The problem of patents

also highlighted a previously unknown toxicity data source of much needed mix :. Patent applications

For the latter analysis, a scientist at the Center analyzed the database of patents of other pesticide products approved in a similar manner.

Among the key findings in the review of approvals for the four companies:

  • 69% of these products (96 of 140) had at least one patent application is cashed or synergy between the active ingredients in the product demonstrated;
  • 72% of patent applications claiming identified or demonstrated synergy involved some of the most highly used pesticides in the United States, including glyphosate, atrazine, 2,4-D, dicamba and neonicotinoids thiamethoxam , imidacloprid and clothianidin, among others.

“It is alarming to see how common it was for the EPA to ignore how these chemical mixtures might endanger the health of our environment,” Donley said. “It is quite clear that the chemical companies knew about these potential dangers, but the EPA did not bother to request this information from them or dig a little deeper to find themselves.”

The EPA can only approve a pesticide will not cause unnecessary if adverse effects on the environment. When a chemical company develops a new product, and seek the approval of that product from the EPA, often seek patent protection in the mix. Such an application is often accompanied by data showing the synergistic toxicity of organisms that will be the target of chemicals.

The EPA says that often can not assess the potential synergistic impacts, as it lacks data. However, this report concludes that the patent database contains substantial data on the synergistic effects that can be used to fill some of the gaps that exist data on the toxicity of the mixture of plants and animals.

The fact that the EPA states that recently realized this data source indicates that pesticide companies are collecting information about the synergistic effects of products for submission to the Patent Office and brands are choosing not to share with the EPA.

“The EPA has turned a blind eye for too long to the fact that mixtures of pesticides can have dangerous synergistic effects,” Donley said. “Now that we know about all the data that are out there, the EPA must take steps to ensure that wildlife and the environment are protected from these chemical cocktails.”
