Biomedical Effects and Toxicity
Biomedical Effects and Toxicity:
To determine the metabolic disposition of (l4)C-2-mercaptobenzothiazole (MBT) and (14)C-2-mercaptobenzothiazole disulfide (MBTS) male and female rats were dosed topically. Topical doses were 36.1 ug/animal for (14)C-MBT and 33.6 ug/animal for (14)C-MBTS. Although more MBT passed through the skin than MBTS and although relative to rats, guinea pigs absorbed a greater percentage of the dose (33.4% compared to 16.1-17.5% of the MBT and 12.2% compared to 5.94-7.87% for MBTS) the disposition of radioactivity derived from the two compounds was similar. Washing of the skin removed more of the radioactivity from guinea pigs than from rats. For both sexes of rats dosed iv with (14)C-MBT 0.602 mg/kg) or (14)C-MBTS 0.571 mg/kg) disposition of the compounds was similar. In 72 hr, 90.9-101% of the dose appeared in the urine and 3.79-15.1% in the feces. At this time a small portion of the administered radioactivity (1.52-1.96% of the dose) remained associated with erythrocytes. Oral dosing of rats for 14 days with unlabeled MBT (0.510 mg/kg/day) prior to a single dose of (14)C-MBT (0.503 mg/kg) or with unlabeled MBTS (0.521 mg/kg/day) prior to a single dose of (14)C-MBTS (0.730 mg/kg). For both sexes disposition of the compounds was similar. At 96 hr after dosing a small portion of the administered radioactivity (1.20-1.69% of the dose) remained associated with erythrocytes most of which was bound to the membranes. For both compounds and sexes 60.8-101% of the radioactivity administered appeared in the urine and 3.46-9.99% in the feces in 96 hr. At the time only trace amounts of radioactivity remained in tissues other than blood. Of these tissues thyroid contained the highest concentration. In the urine there was a detectable MBT or MBTS but there were two metabolites one of which was identified as a thioglucuronide derivative of MBT. The other was possibly a sulfonic acid derivative of MBT. In conclusion there were similarities in absorption, distribution, and metabolism of (14)C-MBT and (14)C-MBTS in rats and in guinea pigs, indicating that (14)C-MBTS was readily converted to (14)C-MBT.

Environmental Fate and Exposure Potential
Environmental Fate/Exposure Summary:
TERRESTRIAL FATE: When released to soil, 2,2'-dibenzothiazyl disulfide will be categorized as immobile(3) based on estimated Koc values ranging from 10,960 to 755,000 (1,2). The rate of biodegradation in soil is probably slow (0.8% theoretical BOD in 2 weeks in an aqueous screening test using soil inoculum)(4).
AQUATIC FATE: Volatilization of 2,2'-dibenzothiazyl disulfide from water will not be an important fate process based on an estimated Henry's Law Constant of 2.34X10-13(1,2). Insufficient data are available to predict the relative importance or rate of biodegradation in aquatic conditions although one aqueous screening biodegradation test would suggest slow biodegradation(SRC). Aquatic bioconcentration factors of 1.0-7.2 and 1.4-51 for concentrations of 0.2 mg/l and 0.02 mg/l, respectively, were measured for carp(3). Since 2,2'-dibenzothiazyl disulfide absorbs light >290 nm(4), it has the potential to photolyze, alhtough the kinetics of the potential photlysis are not known(SRC). It is possible that 2,2'-dibenzothiazyl disulfide will adsorb to sediment or particulate material in an aquatic system based on its estimated Koc(SRC).
ATMOSPHERIC FATE: If released to the atmosphere, 2,2'- dibenzothiazyl disulfide will degrade in the ambient atmosphere by reaction with photochemically produced hydroxyl radicals with an estimated half-life of 1.3 hrs(1).
