Comparative Inspection of Terbufos in Blood from Head Skin by GC-MS

This paper selects a typical poisoning case of pesticide topical on head. Technicians extracted the victim's blood, vomit and swabs, and toxicant tests were under Condition-A and Condition-B. Terbufos ingredients were detected from the blood and swabs, but not found in vomit. Compared Condition-B to Condition-A: it has increased the column efficiency and improved the separation of Terbufos, thereby improving the detection sensitivity of Terbufos. The Condition-B method selects more than one mass fragment peak for scanning, which is of high sensitivity and less impurities interference. While using Terbufos standards for retention time comparison, the results are accurate and reliable.
