4.2 Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin and eyes. ACUTE/CHRONIC HAZARDS: This compound is toxic by ingestion. It may cause irritation of the skin and eyes. When heated to decomposition it emits toxic fumes of nitrogen oxides and chlorine.
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out.

12.2 Persistence and degradability
Nitrofen degraded slowly under aerobic and anaerobic conditions with a sewage inoculum, but only in the presence of an external source of carbon and energy; after 88 days of incubation 6% and 4% degradation occurred under aerobic and anaerobic conditions, respectively(1). Four unspecified products were formed in the aerobic experiment, all more hydrophilic than the parent compound(1). The corresponding amine was identified as a biodegradation product of nitrofen(2). Nitrofen, present at 100 mg/L, reached 2% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(3). Nitrofen was degraded slowly by soil microorganisms during the first week and persisted more than 4 weeks when it was the sole source of carbon(4). When other sources of carbon were added, degradation occurred in 3 weeks(4). After 16 weeks of incubation in laboratory experiments, 15 and 38% of the initial concentration (10 ppm) of nitrofen remained in sandy loam (0.7% organic matter, pH 7.0) and muck (36.7% organic matter, pH 7.0) soils, respectively, 94% and 82% nitrofen remained in the same soils that were sterilized(5). Nitrofen slowly but completely biodegraded to carbon dioxide in typical soils likely proceeding through diphenyl ether cleavage(6). In a river die-away test using Asahi River (Japan) water, 1% of the nitrofen remained after 50 days incubation at 20°C(7).
12.3 Bioaccumulative potential
The BCF of nitrofen in orange-red killifish (Oryzias latipes), exposed for 10 weeks to 50 and 5.0 ug/L was 2900-5370 and 2720-4220, respectively(1). Nitrofen bioconcentrated in algae, snails, mosquito larvae, and fish in a 3-day model aquatic ecosystem; <20% of the herbicide was found as metabolites(2). A 33-day model terrestrial-aquatic ecosystem in which 1.29 kg/ha of nitrofen was injected into paddy sand containing rice seedlings(2). The BCFs for fish, mosquito larvae, snails, and algae in this experiment were 1550, 3190, 2770, and 405, respectively(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of nitrofen can be estimated to be 7,800(SRC). According to a classification scheme(2), this estimated Koc value suggests that nitrofen is expected to be immobile in soil(SRC). Results of soil thin layer chromatography tests showed that nitrofen is immobile in soil(3). Similarly results were obtained in column leaching studies with both Plainfield sand and muck soils and indicate that leaching of nitrofen from arable soils will be negligible(4). In field experiments in sandy loam, heavy clay, and silty clay soils, <5% of the applied nitrofen was recovered from the 5-10 cm soil level, indicating that minimal leaching had occurred(5).
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.
