> Commenting also on Bobs post about the supply houses, I think its sad that the supply houses still sell this junk.

Maybe this will get their attention

> There is growing concern that poisoning and other adverse health effects are increasing because organophosphorous (OP) insecticides are now being used in combination with pyrethroid (PYR) insecticides to enhance the toxic effects of PYR insecticides on target insects, especially those that have developed PYR resistance. Results showed high prevalence of exposure to OP and PYR pesticides and our preliminary analyses provided some suggestion that the higher exposure group had lower sperm concentration.

> These biomonitoring pilot results suggest a specific exposure profile, and the specific pesticide exposure mixture is of concern because of possible synergistic effects on humans. All of the 18 males in our sample had diethylthiophosphate (DETP) and parathion (PNP) OP metabolites and all had phenoxybenzoic acid (3PBA) PYR metabolites. Urinary concentrations in our pilot sample were well above US general population levels.

> Compared to non-exposed controls, the percentages of slow progressive and non-progressive motile sperm among 18 sprayers of OP and PYR pesticides were twice as high. We are examining this relationship further in a larger study of 202 men currently underway.
