Analytical Method for Individual Ethylene-bis-dithiocarbamate Fungicides Residues in Agricultural Products

Year: 1982

Type: article

Abstract: A method was developed for the determination of individual ethylene-bis-dithiocarbamates (Zineb, Maneb, Mancozeb and Polycarbamate) in agricultural products.This analytical method consists of four procedures; washing or wiping with 10% surface active agent solution, filtration through a Millipore filter, acidic hydrolysis in the presence of stannous chloride and quantitative measurement of carbon disulfide, ethylenediamine (EDA), dimethylamine (DMA) and bivalent metals [zinc (Zn) or manganese (Mn)].The fungicides were identified as follow: Zineb was based on Zn and EDA, Maneb was based on Mn and EDA, Mancozeb was based on Mn, Zn and EDA, Polycarbamate was based on Zn and DMA. In this method, recoveries of Zineb, Maneb, Mancozeb and Polycarbamate from five agricultural products fortified at a level of 0.2-2.0ppm averaged 61.0, 54.4, 52.0 and 63.2%, respectively.
