Last week, the Environmental Protection Agency (EPA) released a 500-page draft report on the environmental impacts of atrazine, the second most widely used weed killer in the United States and a chemical known as a water pollutant with potentially serious adverse health effects.

When it released a 408-page report on genetically engineered (GE) crops yesterday, the National Academies of Sciences (NAS) said claims about GE crops—both pro and con—“have created a confusing landscape for the public and policy-makers.” But the report itself might not clear up all the confusion.
If you’re an urban parent, you might spend time worrying about your children’s exposure to pesticides through the foods they eat and the lawns on which they play. Now, a new look at kids living in agricultural communities might put those concerns in perspective.
What do grizzly bears, gray wolves, California condors, and coho salmon have in common? All are protected by the Endangered Species Act (ESA) and all are likely to be harmed by three commonly used pesticides, according to a new report from the U.S. Environmental Protection Agency (EPA). In fact, these three pesticides—chlorpyrifos, diazinon, and malathion—are likely to harm 97 percent of the plants and animals listed under the ESA. Read more
Pointing to a growing consensus in the scientific community about pesticides’ impacts on honey bees and other pollinators, beekeepers in the state have worked with environmental groups to effect local policy. Last week, the Maryland state legislature passed the Pollinator Protection Act, which would ban consumers from buying pesticides that contain “neonics” beginning in 2018. Read more
Monarch butterflies are in serious trouble. Perhaps the most iconic insect in the United States, this butterfly has existed for countless millennia and, every year, it accomplishes the longest known migration of any insect in the world.
Monarch butterflies have been decimated over the past 20 years due to the loss of milkweed in the Midwest. This once common plant is the only food the butterflies’ larvae eat, and as milkweed goes, so go the monarchs. What’s worse, is the fact that these butterflies’ main summer mating grounds are smack in the middle of the U.S. Corn Belt, where milkweed has been almost eliminated due to the large-scale use of glyphosate (or Roundup) herbicide on genetically engineered corn and soybeans.

One year ago, an agency of the World Health Organization’s International Agency for Cancer Research (IARC) declared that glyphosate (or Roundup), the world’s most widely used herbicide, probably causes cancer. Then, in the fall, the European Food Safety Agency’s (EFSA) responded with an assessment that disagreed with the WHO’s findings. Read more
Most scientists, farmers, and regulators usually consider the health effects of pesticides one at a time. But that’s not always how they’re used.
A new report by researchers at the University of California Los Angeles’s Sustainable Technology & Policy Program (STPP) took a rare look at several pesticides—all fumigants—that are often applied in combination, chloropicrin, 1,3-dichloropropene, and metam salts. It found that when mixed together, the chemicals can interact and become more toxic, endangering and leaving farmworkers, neighbors, and schoolchildren without adequate protection.
“We know these are being applied on purpose together,” and some have similar health effects, including cancer, says report co-author Susan Kegley, principal, and CEO of the California-based Pesticide Research Institute.
Millions of pounds of these three pesticides are commonly used in combination to grow strawberries, tomatoes, peppers, grapes, nuts, and other crops. All together about 30 million pounds were used on California farm fields in 2013 alone and together they account for about a fifth of all pesticides used in the state.
The U.S. Food and Drug Administration (FDA), the nation’s chief food safety regulator, plans to start testing certain foods for residues of the world’s most widely used weed killer after the World Health Organization’s cancer experts last year declared the chemical a probable human carcinogen.

Colorado is now home to some of the nation’s first certified organic cannabis, which comes with a blessing from federal regulators. CBDRx, a Longmont, Colorado cannabis farm, has secured a certification to market its products with the organic seal from the U.S. Department of Agriculture (USDA), a major coup for the plant’s enthusiasts.
