Chan School of Public Health<\/a>.<\/p>\n<p>The study appeared online in the July 23 issue of the Journal of Environmental Chemistry.<\/p>\n<p>\u201cData from this study clearly demonstrated the ubiquity of neonicotinoids in pollen and honey samples that bees are exposed to during the seasons when they are actively foraging across Massachusetts. Levels of neonicotinoids that we found in this study fall into ranges that could lead to detrimental health effects in bees, including CCD,\u201d said Chensheng (Alex) Lu, associate professor of environmental exposure biology in the Department of Environmental Health at Harvard Chan School and lead author of the study.<\/p>\n<p>Since 2006, there have been significant losses of honeybee colonies. Scientists, policymakers, farmers, and beekeepers are concerned with this problem because bees are prime pollinators of roughly one-third of all crops worldwide.<\/p>\n<p>Previous studies analyzed either stored pollen collected from hives or pollen samples collected from bees at a single point in time. In this study, the Harvard Chan School researchers looked at pollen samples collected over time \u2014 during spring and summer months when bees forage \u2014 from the same set of hives across Massachusetts. Collecting samples in this way enabled the researchers to determine variations in levels of eight neonicotinoids, and to identify high-risk locations or months for neonicotinoid exposure for bees. The researchers worked with 62 Massachusetts beekeepers who volunteered to collect monthly samples of pollen and honey from foraging bees, from April through August 2013, using pollen traps on the landings of beehives. The beekeepers then sent the samples to the researchers.<\/p>\n<p>The researchers analyzed 219 pollen and 53 honey samples from 62 hives, from 10 out of 14 counties in Massachusetts. They found neonicotinoids in pollen and honey for each month collected, in each location \u2014 suggesting that bees are at risk of neonicotinoid exposure any time they are foraging anywhere in Massachusetts.<\/p>\n<p>The most commonly detected neonicotinoid was imidacloprid, followed by dinotefuran. Particularly high concentrations of neonicotinoids were found in Worcester County in April, in Hampshire County in May, in Suffolk County in July, and in Essex County in June, suggesting that, in these counties, certain months pose significant risks to bees.<\/p>\n<p>The new findings suggest that neonicotinoids are being used throughout Massachusetts. Not only do these pesticides pose a significant risk for the survival of honeybees, but they also may pose health risks for people inhaling neonicotinoid-contaminated pollen, Lu said. \u201cThe data presented in this study should serve as a basis for public policy that aims to reduce neonicotinoid exposure,\u201d he said.<\/p>\n<p>Other Harvard Chan School authors of the study included doctoral student Chi-Hsuan Chang, research fellow Lin Tao, and research associate Mei Chen.<\/p>\n<p>Funding for this study came from the Woodshouse Foundation and the Harvard-NIEHS Center for Environmental Health.<\/p>\n\n\n<\/div>\n\n\t\t","protected":false},"excerpt":{"rendered":"<p>In a new study, Harvard researchers looked at pollen and honey samples collected from the same set of hives across Massachusetts.

In this study, the Harvard Chan School researchers looked at pollen samples collected over time \u2014 during spring and summer months when bees forage \u2014 from the same set of hives across Massachusetts. Collecting samples in this way enabled the researchers to determine variations in levels of eight neonicotinoids, and to identify high-risk locations or months for neonicotinoid exposure for bees. The researchers worked with 62 Massachusetts beekeepers who volunteered to collect monthly samples of pollen and honey from foraging bees, from April through August 2013, using pollen traps on the landings of beehives.
