Persistence and degradability
AEROBIC: 2-(Thiocyanomethylthio)benzothiazole, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test classifying the compound as not readily biodegradable(1). By contrast, thiocyanic acid, (2-benzothiazolylthio) methyl ester, at an initial concentration of 42 umol/L, was 95% degraded in 9 to 12 days using a mixed culture pilot plant designed for treatment of tannery wastes; 2-(methylthio)benzothiazole was the main product(2). Using OECD Method 301B (CO2 Evolution Modified Sturm Test), 96% of initial 2-(thiocyanomethylthio)benzothiazole degraded by day 28(3); however, it took >10 days for the degradation to increase from 10 to 60%, thereby classifying the compound as not readily biodegradable under the conditions of the test(3). Soil samples were incubated in the dark with the test compound at 25 deg C for 58 days; a soil aerobic metabolism half-life of 1.4 days was reported(3).
Bioaccumulative potential
Using carp (Cyprinus carpio) which were exposed over an 8-week period, a BCF range was of <14-20 and <153 to 268 was measured for 2-(thiocyanomethylthio)benzothiazole at concentrations of 2 and 0.2 ug/L, respectively(1). Using bluegill sunfish (Lepomis macrochirus) and a 28-day exposure period, BCF values of 44 and 184 were determined in the fillet and whole fish respectively(2). According to a classification scheme(3), BCF values of <30 are low, 30-100 are moderate and from 100 to 1,000 are high(SRC).
Mobility in soil
The adsorption of 2-(thiocyanomethylthio)benzothiazole was measured in five different soil types (sand, sandy loam, silt loam, clay and clay loam) with resulting Koc values ranging from 282 to 7896(1). Two soil adsorption studies conducted using OECD guidelines in four soil types determined Koc values of 633, 1,730, 2,060 and 2,270(2). According to a classification scheme(3), these Koc values suggest that 2-(thiocyanomethylthio)benzothiazole is expected to have moderate to no mobility in soil.
Other adverse effects

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
