Sorry for beeing a little long in answering questions .

The information that some residues of imidaclopride were recently found in underground water in Canada has been given by a scientist called Dr Bonmatin, during his last conferences in beekeeping meetings last fall .

Dr Bonmatin is a researcher working in the C.N.R.S. institution (Centre National de la Recherche Scientifique).

He is very well known in the french beekeeping world, because he spent most of his time, during the last four or five years, working  on the problems that arose for beekeepers with the arrival on the market  of this new generation or neurotoxics . He has clearly established that flowers of plants which seeds were treated with imidaclopride were containing in  pollen and nectar small quantities of the chemical (2 to 3 ppb in the pollens of sunflower, 1 to 2 ppb in the pollen of maïs) .

And those quantities, if they are not letal, are very clearly  important enough to affect several behaviors of our bees .

I am trying to contact him, but it is not possible immediatly .
I'll let you know as soon as I get the answer .
