- Toxicity to microorganisms: no data available
Persistence and degradability
Decomp in soil is aided by microorganisms such as bacillus cereus var mycoides & takes place within a few years.
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 deg 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).
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 deg 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).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
