FRISCO — Neonicotinoid pesticides are spreading throughout the environment with as-yet unknown effects on human health, according to a new study by the U.S. Geological Survey.
The agency found the systemic pesticides in more than half the streams sampled across the country and in Puerto Rico during a survey between 2011 and 2014. This study is the first to take a nationwide look at the prevalence of neonicotinoid insecticides in agricultural and urban settings.
The research spanned 24 states and Puerto Rico and was completed as part of ongoing USGS investigations of pesticide and other contaminant levels in streams. Sourced through Scoop.it from: summitcountyvoice.com.
GR: The levels are low, but here’s the thing: They are not alone. Several other classes of chemical wastes are in the water. We know that insects such as dragonflies are responding to something in the water, so it would be prudent to asses the combined impact of neonicotinoids and other chemicals on wildlife.
