SYMPTOMS: Symptoms of exposure to this compound may include eye and mucous membrane irritation. It can cause contact dermatitis, conjunctivitis, exacerbation of seborrhea and acne vulgaris. Eye contact may result in a smarting sensation. Ingestion of this material can cause central nervous system disturbances. Symptoms resulting from exposure to this compound include disorientation, staggering gait, slurred speech, crying out, episodes consisting of stiffening into a sitting position, extending of extremities, flexing of the fingers and dorsiflexing the toes. It may also cause jaundice, aplastic anemia, bleeding, convulsive seizure or death. It may irritate tender areas of the skin. It may also cause severe eye injury. Other symptoms are desquamation about the nose, dryness of face, a slight tingling sensation and a bullous eruption in the antecubital fossae. Irritation of the gastro-intestinal tract and coma are possible. It may cause purpuric or ecchymotic areas. ACUTE/CHRONIC HAZARDS: This compound is irritating to the skin, eyes and mucous membranes.

    12.Ecological information

    12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (fathead minnow); Conditions: freshwater, flow through, 25°C, pH 7.3, hardness 45.0 mg/L CaCO3, alkalinity 47.0 mg/L CaCO3, dissolved oxygen 6.1 mg/L; Concentration: 110000 ug/L for 96 hr (95% confidence interval: 106000-114000 ug/L) /98% purity
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water Flea) age <24 hr neonate; Conditions: freshwater, renewal, 19.4-20.3°C, pH 8.2-8.6, hardness 134-136 mg/L CaCO3, alkalinity 179-182 mg/L CaCO3, dissolved oxygen > or =7.7 mg/L; Concentration: 24000 ug/L for 21 days (95% confidence interval: 21000-27000 ug/L); Effect: reproduction, decreased progeny counts/numbers /98.68% purity
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available
  • 12.2 Persistence and degradability

    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 potential

    BCF 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 soil

    Using 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 effects

    no data available

    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.
