Not necessarily true, soil borne dusts adhsorb electrostatically to the
exoskeleton. We've done extensive research in smelter areas where soils are
loaded with heavy metals. The main exposure route is from the air borne
fine particulates from the smokestakes and from re-entrained dusts.
My point - in these settings, the direct surface EXPOSURE to the bee
exceeded that of the translocation EXPOSURE. I'd expect to see some of the same
for pesticides in soils, until they degrade. Jerry
