Toxicity of methylenebisthiocyanate (MBT) to several freshwater organisms
The organo-sulfur compound methylenebisthiocyanate (MBT) has successfully been used as preservative in latex emulsions, starches and gums, acrylic fibers, coatings, curing salts for hide and leather and cutting oil systems. The greatest application of MBT is for cooling water systems and paper mill systems as effective inhibitor of algae, fungi and bacteria, in particular the sulfate reducing anaerobic Desulfovibrio sp. However, MBT hydrolyzes rapidly above pH 8.0. The half-conversion time at pH 8.0 is about 4.5. No data are available on residues of MBT in the aquatic environment. Information on the toxicity of MBT, except for its effects on bacteria and algae, is scarce. Therefore research was carried out to evaluate its risk to aquatic life.
