A new study from the U.S. Geological Survey, accepted for publication online ahead of print in the journal Enviromental Toxicology and Chemistry, titled, "Pesticides in Mississippi air and rain: A comparison between 1995 and 2007,"[i] reveals that Roundup herbicide (aka glyphosate) and its still-toxic degradation byproduct AMPA were found in over 75% of the air and rain samples tested from Mississippi in 2007.

The researchers evaluated a wide range of pesticides currently being used through weekly composite air and rain sampling collected during the 1995 and 2007 growing seasons in the Mississippi Delta agricultural region.
