Analysis of Dithiocarbamate Pesticides in Water Using Headspace-GC/MS

On April 1, 2015, dithiocarbamate pesticides were added to the "No. 5 pesticides of the complementary items of Drinking Water Quality Standards" by Japan's Ministry of Health, Labour and Welfare. The headspace-GC/MS method (Appendix Method 24) is specified as a reference test method. The dithiocarbamate pesticides decompose into carbon disulfide in the presence of acids. Accordingly, dithiocarbamate pesticides (zineb, ziram, thiram, propineb, polycarbamate, mancozeb, and maneb) are decomposed by hydrochloric acid, and are then measured as carbon disulfide.
This datasheet introduces the results of an investigation regarding quantitative analysis of carbon disulfide in water using headspace-GC/MS.
