Persistence and degradability
Data regarding the biodegradation of o-chlorostyrene in either soil or aquatic systems were not available. (SRC)
Bioaccumulative potential
An estimated BCF of 100 was calculated for o- chlorostyrene(SRC), using an estimated log Kow of 3.54(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(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for o-chlorostyrene can be estimated to be 860(SRC). According to a classification scheme(2), this estimated Koc value suggests that o-chlorostyrene is expected to have low 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.
