"EPA today proposed new restrictions on the use of the weedkiller atrazine, a widely used agricultural chemical.
But environmentalists say EPA's plan weakens protections and would allow 50% more of the endocrine-disrupting herbicide linked to birth defects and cancer to end up in waterways.
Atrazine is one of the most commonly used herbicides in the United States. It is used on cultivated grass and a variety of crops. It's used mostly on corn, sorghum and sugar cane, but farmers also apply it to wheat, guava, macadamia nuts and Christmas trees, among other crops."
