Does anyone know of anyone who provides of testing for such herbicides?
One of the huge problems is that we don't know what these biocides break down into. The primary, secondary, and even tertiary breakdown products can be more toxic -- more carcinogenic than the original compound. We don't even know what those breakdown products are. You cannot test for something you don't even know what it is. Most insecticides are neurotoxins. Their breakdown products could still be neurotoxic but we don't even know what they are. Just saw a news story that autism has increased 72 percent in 5 years and is now 1 in 50 American children.
