Test materials and reference standards

The test material for this study was Lorsban 4E Insecticide in 2.5-gallon plastic jugs, as well as Lorsban 50W in 5-pound bags. The reference standards were chlorpyrifos (0,0-diethyl-0-[3,5,6-trichloro-2-pyridinyl] phosphorothio-ate), CAS No. 002921-88-2 and 3,5,6-TCP (3,5,6-tiichloro-2-pyridinyl). 

The chlorpyrifos reference standard was used in conjunction with the analysis of coverall dosimeter sections (arms, legs, torso), air tubes, Gelman filters, head patches, and handwashes, while the 3,5,6-TCP was used as the reference standard during urine analysis.
