12.2 Persistence and degradability
AEROBIC: Utilizing a CO2 evolution test with a freshly prepared activated sludge inoculum, methylisothiazolinone reached 54.1, 55.8 and 47.6% CO2 evolution, at initial concentrations of 0.3, 0.03 and 0.01 ppm, respectively, over a 28 day incubation period; the results classified the compound as inherently biodegradable and demonstrated a dependence on concentration. Microcosm studies in aerobic water found degradation of methylisothiazolinone to be primarily due to biodegradation based on tests using sterile controls. The half-life of methylisothiazolinone in an aerobic microcosm using river water and sediment was 9 days(1).
12.3 Bioaccumulative potential
A BCF of 3 was reported in bluegill sunfish (Lepomis macrochirus) for methylisothiazolinone(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of methylisothiazolinone can be estimated to be 12(SRC). According to a classification scheme(2), this estimated Koc value suggests that methylisothiazolinone is expected to have very high mobility in soil.
12.5 Other adverse effects
no data available
SECTION 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.
