The study should have started at 20 parts per Billion and gone down to lower levels not up. Recent testing in many areas in the U.S., both agricultural and rural, has indicated that it is much more common for bees to be gathering pollen and nectar with neonicotinoid contamination in the1-2 ppB range than in the 20-400 ppB range such as were used in the study. There have been several important studies at these lower levels, however. The high level contaminations used in this study are encountered only in special situations- like hives near a cornfield using coated seeds. Many beekeepers will no longer place hives near corn fields since 99+ percent of all corn seeds are now coated with neonicotinoids.e2huberhttps://www.blogger.com/profile/16551679784281322719noreply@blogger.com
