12.3 Bioaccumulative potentialAn estimated BCF value of 1.2 was calculated for cimetidine(SRC), using an experimental log Kow of 0.40(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will not be an important fate process(SRC).
12.4 Mobility in soilThe Koc of cimetidine is estimated as approximately 39(SRC), using an experimental log Kow of 0.40(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that cimetidine should have very high mobility in soil(SRC). However, cimetidine will exist in both the undissociated and cation form under environmental conditions (pH 5-9), (pKa of 6.8)(4), and no experimental data are available to indicate whether the cation will adsorb to soil more strongly than its estimated Koc value for the undissociated form indicates(SRC).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
