Study of rivers and streams in the Midwest finds neonic insecticide runoff

A new study has added to mounting evidence against a class of insecticides called neonicotinoids…linked in numerous studies to bee declines, the new research looks at neonics’ impacts on surface water.

Researchers with the U.S. Geological Survey looked at 9 rivers and streams in the U.S. Midwest—home to vast plantings of corn and soybeans as well as widespread use of neonics—in the 2013 growing season.

The researchers detected neonics in all the waterways, which included the Mississippi and Missouri Rivers. One systemic pesticide, clothianidin, was found in 75 percent of the water samples.

“We noticed higher levels of these insecticides after rain storms during crop planting, which is similar to the spring flushing of herbicides that has been documented in Midwestern U.S. rivers and streams,” USGS scientist Michelle Hladick, the report’s lead author, said in a statement.

“In fact, the insecticides also were detected prior to their first use during the growing season, which indicates that they can persist from applications in prior years,” Hladick stated…

“The fact that neonics are pervasively contaminating surface waters should be a wake-up call for state and federal regulators…”

The USGS study comes on the heels of findings by researchers from the Netherlands who noted that concentrations of one neonic called imidacloprid were linked to declines in bird population, suggesting “the impact of neonicotinoids on the natural environment is even more substantial than has recently been reported.”

And a global analysis out last month based on 800 peer-reviewed reports found “clear evidence” that neonics pose threats to bees, other pollinators and terrestrial invertebrates like earthworms, which are exposed to neonics through the soil, the treated plant itself and water.

What does it take to get the liberal flag-wavers inside the Obama administration to live up to the most basic standards of ecology? When domestic and foreign research contradicts the statements of corporate chemical producers, the minimum, the least our government must do is to halt the use of these chemical agents for a period of independent in-depth testing.

Other governments have already done so. All the more reason to act up to a standard supposedly embraced by Democrats and their party. How about deeds instead of words, folks?

Thanks, Mike
