Air

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 EPA enables citizens to know the very minimum about the air quality in their region. They use the AQI or air quality index. This index is explained on their site but it is not a comprehensive measure of risk. It merely shows that the air is harmful for people at risk. It doesn’t talk about UFP (ultra fine particles measuring .1 micron or less). These small particles have been shown to be even more harmful than the ones measured by the EPA which range from 10 microns to 2.5 microns.
