12.1Toxicity

• Toxicity to daphnia and other aquatic invertebrates: no data available
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2Persistence and degradability

A second order microbial transformation rate constant of 2.0X10-14 L/organism-hr was determined for niclosamide in natural pond water; degradation was via microbially mediated hydrolysis of the amide(1). The biodegradability of niclosamide in soil was reported as extremely low(2). Niclosamide degraded rapidly in both pond and river sediments incubated under static conditions with half-lives of 1.1 and 3.9 days, respectively(3). Rapid disappearance of niclosamide from water above the sediment was also observed with half-lives of 3.1 and 0.83 days in water above pond and river sediment, respectively(3); degradation in autoclaved samples occurred at a very slow rate indicating a dependence on microbial activity. Aminoniclosamide is the major degradation product for this reaction, representing more than 50% of the extractable radioactivity(3). 11.3, 7.2, 3.5, and 6.2% of the added 14C-niclosamide was present as CO2 after 32 days for cultures incubated under river sediment/aerobic, river sediment/anaerobic, pond sediment/aerobic, and pond sediment/anaerobic conditions, respectively; by 93 days, 37.7, 9.0, 6.8, and 8.7% of the total radioactivity for the same cultures was present as CO2(3). Aminoniclosamide was again the major degradation product detected in water and sediment extracts from this experiment; more aminoniclosamide was formed under anaerobic than aerobic conditions, especially during the first 64 days of incubation(3).

12.3Bioaccumulative potential

An estimated BCF value of 215 was calculated for niclosamide(SRC), using a water solubility of 6.5 mg/l(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms may be low(SRC). Depuration occurred within 72 hours for rainbow trout exposed to 14C-labeled niclosamide. Biliary concentration was high, reaching a 10,000:1 bile to water ratio in 24 hours. The metabolite formed was the glucuronide(4,5).

12.4Mobility in soil

The Koc of niclosamide is estimated as approximately 1600(SRC), using a measured water solubility of 6.5 mg/L(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that niclosamide has low mobility in soil(SRC). Adsorption of niclosamide by sediment reached equilibrium after 4-7.5 hours of shaking; an average Koc value of 3111 +/- 1552 was measured using five different sediments (pH range = 6.8-7.8; organic carbon = 1.9-9.2%)(4). Bottom sediment samples from 3 rivers in the Upper Peninsula of Michigan gave Koc values at 20 deg C of 3510, 946, 766, and 77.9 at pH 6.5, 7, 8, and 9 for the Cedar River, 1210, 1570, 828, and 234 at the same pH values for the Ford River, and 1920, 1580, 532, and 131 at the same pH values for the Tahquamenon River(5).

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal 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.
