Sampling and Analytical Methods | Maneb/Zineb

Currently the most common analytical method for maneb and zineb is based on acid hydrolysis with the measurement of the released carbon disulfide by head-space GC analysis (Ref. 5.3). The method is nonspecific because it does not distinguish dialkyl dithiocarbamates (such as ziram and ferbam) or thiuram disulfide (such as thiram) from EBDTC.
