The lowest concentrations were seen in South American samples (57 percent). The level of nocive substances (up to 56 nanogram per gram) are not a danger now for humans but is not a good thing for the survival of the species,which is very important in nature for its pollinate action. Bees fertilize more than 90 percent of the world’s 107 major crops. The study found that 34 percent of honey samples were contaminated with “concentrations of neonicotinoids that are known to be detrimental” to bees.

“The levels detected are sufficient to affect bee brain function and may hinder their ability to forage on, and pollinate, our crops and our native plants,”the study says. In fact, a ” colony collapse disorder ” as a  mysterious scourge blamed on mites, pesticides, virus, fungus, or some combination of these factors was found to occur in many cases. Neonicotinoids have been declared a key factor in bee decline worldwide, and the European Union issued a partial ban on their use in 2013. “The actual level of exposure can be substantially higher, as the honey samples analyzed in this study represents an average of nectar collection over time and space,” the study warned.
