net Chinese website reported: After 9 months of review, the US Environmental Protection Agency (EPA) recently issued an interim decision (ID) on the herbicide paraquat dichloride (paraquat)
.
In October last year, the EPA proposed to ban the aerial spraying of paraquat (except for cotton drying purposes).
The interim decision issued this time allows aerial spraying of all approved crops , but at the same time the agency has also formulated specific restrictions.
To protect human health, for example, when aerial spraying, a buffer zone of 50 to 75 feet must be set up around the residence
.
Paraquat is a herbicide used to control invasive weeds in crops such as cotton, corn and soybeans
.
There is no direct substitute for paraquat
.
All paraquat products in the United States are restricted products and can only be used by certified pesticide applicators

.
EPA has taken active measures to ensure that the use of paraquat will not cause unreasonable adverse effects on human health or the environment, and comply with label instructions
.
EPA's 2016 paraquat human health mitigation decision, including a safety awareness action, training for paraquat applicators, and changes to labels and product packaging to help prevent illness, injury or death caused by improper use of paraquat

.
The interim decision issued this time builds on previous work and includes the following executable mitigation measures, which specify application parameters and establish restrictions that further protect individuals from exposure
.
EPA has determined that these mitigation measures are necessary to address paraquat exposure risks, while allowing continued use of this important agricultural tool

.
· Restrict air application, and need to set up residential buffer zone
.
.
·It is forbidden to use high-pressure pistols and backpack sprayers
.
.
· A closed cab or respirator is required for ground spray boom applications
.
.
· Increase the restricted entry interval (REI) for several crops
.
.
In addition, the EPA evaluated hundreds of studies, including published literature on the toxicity and epidemiology of paraquat exposure and adverse health consequences, including Parkinson's disease
.
There are many studies on paraquat and Parkinson's disease of varying quality and conflicting results
.
According to the EPA's 2019 literature review, the latest study of an agricultural health research cohort was released in 2020, reporting that there is no association between paraquat exposure and Parkinson's disease
.
It is worth noting that this updated study does not repeat the early 2011 findings of AHS considered by the EPA, and indicates that there may be a potential association
.
According to FIFRA requirements, after a thorough review of the best available science, the EPA has not yet found a clear link between exposure to paraquat label use and adverse health outcomes such as Parkinson's disease and cancer

The new safety measures announced this time will significantly reduce potential human health risks and protect all potential human health outcomes including Parkinson's disease
