The acceptability of a chlorine bleach pretreatment for removal of chlorpyrifos residues from cotton and polyester/cotton fabrics

Agricultural Chemical Percutaneous Absorption and Decontamination

“…Chlorine bleach pretreatment offers the advantage of oxidative degradation of organophosphates -for example, chlorpyrifos degraded into 3,5,6-trichloro-2-pyridinol (Perkins et al, 1996). Laundering protocols for the organophosphate chlorpyrifos residue removal were investigated utilizing three chlorpyrifos-containing pesticides: Dursban PC Termiticide and Insecticide (PCT) (emulsifiable concentrate), Dursban Micro-Lo Termiticide (emulsifiable concentrate), and Empire Insecticide (capsule suspension formulation) (Dow AgroScience, Inc., Indianapolis, IN) -with fenthion (Baytex, Bayer CropScience, Victoria, Australia) and permethrin (Perigen, Bayer CropScience) included for comparison purposes (Table 27.14) (Fitzgerald and Manley-Harris, 2005).…”
