| Abstract |
Two different approaches were used to identify potentially harmful impurities present in technical grade pesticides. One approach was a theoretical approach that involved a literature search, study the manufacturing processes, identifying the main reactions and the numerous side reactions that may occur, listing the potential impurities that may result, and estimating the likelihood of the occurrence of such impurities at ug/g or lower levels in the final product. The second approach was experimental and involved the use of combined gas chromatography-mass spectrometry (GC-MS) to identify and quantify the major impurities actually present in technical-grade materials. In addition to the above two tasks the program also included maintaining, and assaying a repository of selected technical-grade pesticides. |
