Persistence and degradability
Five weeks after application of a 10% 14C-carbonyl-labeled ethiofencarb granular formulation to soil under greenhouse conditions, the metabolites (sulfoxide and sulfone) were found in the soil, and the parent compound was no longer detectable(1). Radiochemical determination of the degradation rate showed that ethiofencarb had a half-life of about 2 weeks under greenhouse conditions(1). Similar rates of degradation were determined under field conditions(1).
Bioaccumulative potential
An estimated BCF of 7.4 was calculated for ethiofencarb(SRC), using a log Kow of 2.04(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). In addition, ethiofencarb undergoes hydrolysis(4,5) and photolysis(6) in aquatic environments, and bioconcentration is not expected to be a significant fate process(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for ethiofencarb can be estimated to be 230(SRC). According to a classification scheme(2), this estimated Koc value suggests that ethiofencarb is expected to have moderate mobility in soil.
Other adverse effects

Disposal methods
ProductThe 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.
