AEROBIC: DEET, present at 100 mg/L, did not biodegrade in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI(1). However, in a OECD 301B test DEET was shown to biodegrade 83.8% in 4 weeks using activated sewage sludge and measuring carbon dioxide produced(2). DEET reached 30% and 37% of the theoretical oxygen demand and chemical oxygen demand after 7 days in another test, but biodegradation seemed to halt after reaching 40 and 48%, respectively(2). DEET was shown to biodegrade using Po River water, forming three transformation products(3). Pseudomonas putida DTB (isolated from activated sludge from a municipal wastewater treatment plant in Ithaca, NY) degraded DEET to 3-methylbenzoate and diethylamine under aerobic conditions(4).
12.3 Bioaccumulative potentialBCF values of <2.4 and 0.8-2.4 were measured using carp (Cyprinus carpio) which were exposed to 0.05 and 0.50 mg/L of DEET, respectively, over a 6-week period(1). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilUsing a structure estimation method based on molecular connectivity indices(1), the Koc of DEET can be estimated to be 115(SRC). According to a classification scheme(2), this estimated Koc value suggests that DEET is expected to have moderate mobility in soil.
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 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.
Contaminated packagingContainers 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.
