  • 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

DECOMP IN SOIL IS AIDED BY MICROORGANISMS SUCH AS BACILLUS CEREUS VAR MYCOIDES & TAKES PLACE WITHIN A FEW YEARS.

12.3 Bioaccumulative potential

An estimated BCF value of 0.56 was calculated for sodium 2,4-dichlorophenoxyethyl sulfate(SRC), using an experimental water solubility of 2.5X10+5 mg/l at 25°C(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of sodium 2,4-dichlorophenoxyethyl sulfate is estimated as approximately 4.7(SRC), using a measured water solubility of 2.5X10+5 mg/l at 25°C(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that sodium 2,4-dichlorophenoxyethyl sulfate is expected to have very high mobility in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations
