12.Ecological information

12.1 Toxicity

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

12.2 Persistence and degradability

STUDIES WITH SOIL MICROFLORA INDICATED THAT BREAKDOWN OF AMIBEN OCCURRED...& THAT THE CARBOXYL WAS CLEAVED SLOWLY BUT STEADILY.

12.3 Bioaccumulative potential

Based on a measured water solubility of 700 mg/L at 25°C(2) and a regression derived equation(1), a BCF of 15.34 can be estimated for Amiben(SRC). This BCF value suggests that Amiben may not bioconcentrate in aquatic organisms(SRC).

12.4 Mobility in soil

Amiben is expected to have anionic properties in most soil systems under environmental conditions (pH 5-9). When a column of Ella island soil type (pH 3.8, 1.6% organic matter, 82.7% sand, 12.2% silt, and 5.2% clay) was perfused for 160 days with a microbial medium containing 5.7 and 26.9 ppm (14)-COOH-labelled Amiben, 1.4 ppm (24.6%) and 5.0 ppm (18.5%) Amiben adsorbed to the soil, respectively. When a column of Kewaunee clay soil type (pH 6.4, 3.8% organic matter, 14% sand, 35.1% silt, and 48.7% clay) was perfused for 160 days with a microbial medium containing 5.7 and 26.9 ppm 14COOH-labelled Amiben, 0.6 ppm (11.1%) and 2.6 ppm (9.8%) Amiben adsorbed to the soil, respectively. When a column of Poygan silty clay soil type (pH 7.2, 10% organic matter, 6% sand, 58.9% silt, and 33.6% clay) was perfused for 160 days with a microbial medium containing 5.7 and 26.9 ppm 14COOH-labelled Amiben, 1.4 ppm (24.6%) and 5.4 ppm (20.1%) Amiben adsorbed to the soil, respectively. Therefore, soil pH and organic matter content are the primary factors controlling Amiben adsorption with higher adsorption to soil occurring either at a low pH with a low organic matter content or at a neutral pH with a high organic matter content(1).

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.
