• GC/MS

Products of a thermal reaction of chlorpyrifos were analyzed by LC/MS and GC/MS. As a result, it was found that chlorpyrifos undergoes an elimination reaction of phosphate by a thermal reaction. Furthermore, it is indicated that the structural analogue of 2,3,7,8-TCDD arises by a thermal reaction of chlorpyrifos. In addition, the toxicity of the products of the thermal reaction of chlorpyrifos, evaluated by DR-CALUX((R)), was higher than that of chlorpyrifos itself.
