2-mercaptobenzothiazole (mbt) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires. given its wide use in household articles and industrial rubber products it has a high potential to migrate into the environment. humans can be exposed by dermal, oral, or inhalative routes. incorporated mbt is excreted in urine, mainly as

- How is MBT diluted?
- This starting solution (10 mg L −1) was gradually diluted for the preparation of the working standards, to achieve standard concentrations of 1000 μg L −1, 100 μg L −1, and 10 μg L −1. The internal-standard stock solution was prepared by diluting 10 mg MBT in a 10 mL volumetric flask with acetonitrile (1000 mg L −1 ).

- How much MBT is found in a urine sample?
- MBT was found in only one urine sample from the unexposed humans, at a value of 10.8 μg MBT per liter, whereas it was found in all samples from the tested workers at values of up to 6210 μg MBT per liter. 2-Mercaptobenzothiazole (MBT, benzothiazole-2-thiol, CAS 149-30-4) was introduced to rubber production in the late 1940s [ 1 ].
- What is the LOQ of MBT?
- The established LOD for MBT was 0.4 μg L −1 (0.0024 μmol L −1) in urine, and the corresponding LOQ was calculated to be 1 μg L −1 (0.006 μmol L −1) (Fig. 2 ). Having urine samples from persons in contact with MBT made it possible to compare several hydrolysis procedures.
