- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
The effects of dichlorine-substituted anilines on Guelph loam were studied. 2,5-Dichloroaniline at concentrations of 5 to 100 ug/g soil was inhibitory against the oxidation of the nitrogen of ammonia to nitrite nitrogen, but not nitrite nitrogen to nitrate nitrogen. It showed almost a linear rate of decomposition over the 12 wk period of the expt. The dichloroanilines were more persistent than aniline or the monochloroanilines.
Bioaccumulative potential
An estimated BCF of 35 was calculated for 2,5-dichloroaniline(SRC), using log Kow of 2.92(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate.
Mobility in soil
The Koc for 2,5-dichloroaniline is 355(1). According to a classification scheme(2), this Koc value suggests that 2,5-dichloroaniline is expected to have moderate mobility in soil. However, when released to soil containing humic material, 2,5-dichloroaniline may undergo a covalent chemical bonding resulting in its chemical alteration to a latent form resulting in strong adsorption(3).
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.
