12.2 Persistence and degradability
Degradation of dimethyl tetrachloroterephthalate occurs by successive dealkylations of the two methyl groups at the ester linkages with the formation of monomethyl tetrachloroterephthalate and tetrachloroterephthalic acid(1). 14C-dimethyl tetrachloroterephthalate was added to soil or ground thatch and its degradation measured at 0, 1, 2, 4, 8, 12, and 16 weeks. Degradation was faster in thatch than in soil; 55% and 25% dimethyl tetrachloroterephthalate remained at 4 and 16 weeks, respectively, for thatch cultures. 96% and 78% dimethyl tetrachloroterephthalate remained at 4 and 16 weeks, respectively, for soil cultures(1). Dimethyl tetrachloroterephthalate present in a 0.1%(w/w) dimethyl tetrachloroterephthalate:soil mixture was measured following different temperature and soil moisture regimes. Soil at 10-15 deg C and with low moisture (0.1 kg H2O/kg soil) showed a slow loss of this compound with a half-life of 105 days; soil at 20-30 deg C and with over 0.2 kg H2O/kg soil showed a half-life for dimethyl tetrachloroterephthalate of 11 days(2). The half-life values of dimethyl tetrachloroterephthalate for coarse, medium, and fine soil textures were 44, 15, and 32 days, respectively at optimal temperature and moisture conditions for microbial degradation(2).
12.3 Bioaccumulative potential
A BCF of 1300 was calculated for dimethyl tetrachloroterephthalate, using an experimental log Kow of 4.40(1) and a recommended regression-derived equation(2,SRC). This BCF value suggests that dimethyl tetrachloroterephthalate will bioconcentrate in aquatic organisms(2). Multiple studies show the presence of dimethyl tetrachloroterephthalate in fish(3-12) indicating that bioconcentration of this compound does occur.
12.4 Mobility in soil
Based on an experimental log Kow of 4.40(1), the Koc of dimethyl tetrachloroterephthalate is estimated as approximately 5900 using a regression-derived equation(2,SRC). According to a suggested classification scheme, this Koc value suggests that dimethyl tetrachloroterephthalate is essentially immobile in soil(3). Dimethyl tetrachloroterephthalate is reported to absorb strongly to soil and to be resistant to leaching(4). The minimal movement of dimethyl tetrachloroterephthalate in soil suggests that this compound may adsorb to organic matter or clay(5).
12.5 Other adverse effects
no data available
SECTION 13: Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
