  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water Flea) age <24 hr; Conditions: freshwater, flow through; Concentration: 1200 ug/L for 48 hr (95% confidence interval: 1000-1300 ug/L); Effect: intoxication, immobilization /44% purity formulation

  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Propanil, present at 100 mg/L, reached 21.1% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In a sandy loam soil, 50% CO2 evolution was observed for propanil (initial concentration 436 ppm) after 8 days at 28°C and pH 6(2). Propanil, present at 2000 ppm, degraded 84 and 96% after 5 and 10 days, respectively, incubated at 28°C and pH 5.3(3); 83.6-93.2% degradation was observed after 7 days at 27°C and pH 5.5 (initial concentration of 500 ppm)(4). At initial concentrations of 85 and 850 ppm, propanil degraded 99 and 64.7-70.6%, respectively, in 15 days in rice paddy soils at pHs 5.2-6.3 and 30°C(5). The sterile controls in this study showed 0.3-2.5% CO2 evolution in 25 days(5). Propanil's half-life in soil at 28°C was determined to be 0.1 and 2.3 days at initial concentrations of 10 and 250 ppm, respectively(6).

12.3 Bioaccumulative potential

A whole-fish BCF of 1.6 was determined for fathead minnows (Pimephales promelas) in a flow-through test with 24 hr of exposure; only 1.8% of the total tissue radio-labeled carbon was extractable as propanil(1). According to a classification scheme(2), this BCF suggests bioconcentration in aquatic organisms is low(SRC). Rainbow trout (Salmo gairdneri) readily metabolized propanil to 10 metabolites when radio-labeled propanil was injected into the peritoneum(1). One metabolite was identified as either 3',4'-dichloro-2-hydroxypropionanilide or 3,4'-dichloro-3-hydroxypropionanilide(1).

12.4 Mobility in soil

Koc values ranging from 141 to 800 have been reported for propanil(1,2). Koc values of 306 (sand) and 800 (silt loam) were also reported for propanil(3). According to a classification scheme(4), these Koc values suggest that propanil is expected to have high to low mobility in soil. Based on a soil thin-layer chromatography Rf value of 0.24 measured in a silty clay loam, propanil was classified as having low soil mobility(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.
