Carcinogenicity
The Carcinogen Assessment Group in EPA's Research and Development Office has evaluated ethyl 4,4-dichlorobenzilate for carcinogenicity. According to their analysis, the weight of evidence for ethyl 4,4-dichlorobenzilate is group B2, which is based on inadequate evidence in humans and sufficient evidence in animals. As a group B2 chemical, ethyl 4,4-dichlorobenzilate is considered a probable human carcinogen.
Reproductive toxicity
No information is available on the reproductive or developmental effects of chlorobenzilate in humans. Injury to the sperm and atrophy of the testes have been observed in rats exposed to chlorobenzilate in their diet. Teratogenic effects were not observed in the offspring of rats exposed to chlorobenzilate in the diet or in rabbits exposed by gavage.
STOT-single exposure
The substance is irritating to the eyes and skin. The substance may cause effects on the central nervous system. This may result in impaired functions.
STOT-repeated exposure
no data available
Aspiration hazard
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Persistence and degradability
AEROBIC: The rate at which chlorobenzilate degrades in microbial growth media increases when citrate is incorporated(1). This may be due to a reductive decarboxylation process that the citrate stimulates(1). The half-life of chlorobenzilate in two fine sandy soils was estimated to be 1.5-5 weeks following application of 0.5-1.0 ppm; removal was probably microbial(2). It is decarboxylated to 4,4'-dichlorobenzophenone by a yeast isolated from insecticide treated soil under anaerobic conditions(3,4). In 22 days, 40, 29, and 39% of the (14)C-ring-labeled chlorobenzilate added to sediment-free water samples from 3 fresh water lakes was converted to organic products; no (14)CO2 evolution was detected(5). Addition of sediment to the water samples from the three lakes gave (14)CO2 yields 3.6, 0.0, and 18.3%(5). Chlorobenzilate was metabolized in water from another freshwater lake only when glucose and inorganic nutrients were added and mineralized to (14)CO2 only when sediment was also added to the water(5). Chlorobenzilate, 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(6). Half-lives for chlorobenzilate in Lukang silty clay loam and Pincheng clay ranged from 15.1 days at 10 deg C to 10.8 days at 25 deg C; and 169.1 days at 10 deg C to 29.5 days at 25 deg C, respectively(7).
Bioaccumulative potential
Measured BCF values for carp (Cyprinus carpio) ranged from 224 to 586 and 256 to 709 at concentrations of 20 ug/L and 2 ug/L, respectively(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
The Koc of chlorobenzilate is estimated as 1,500(SRC), using a log Kow of 4.74(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that chlorobenzilate is expected to have low mobility in soil. Kd values of 26 and 7.6 have been reported for Lukang and Pincheng soils, respectively, at 20 deg C; at 40 deg C, the Kd values reported were 41 and 5.3, respectively(4).
Other adverse effects
no data available
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.
