Toxicity of MBS to activated sludge was evaluated by Bayer AG (1990) according to the ISO 8192 -1986/B yielding an EC50 of >10000 mg/l after 3 hours exposure.
A hydrolysis half-life time of MBS of ca. 24 h was observed in deionised
and environmental water buffered at pH 7.0. Benzothiazole-2-thiole (MBT)
and benzothoazole (BT) as hydrolysis products are considered here to
support the assessment of MBS. The observed effects are most probably a
combined effect of the parent substance and the hydrolysis products.
The obtained EC50-value was far about the water solubility, but
describes a realistic scenario for the sewage treatment plant.
