Persistence and degradability
Tributyltin species, obtained by dissolution of tributyltin oxide in water, are sequentially degraded by microorganisms to dibutyltin, monobutyltin (similar to the monobutyltin obtained by dissolution of mono-n-butyltin trichloride), and finally to inorganic tin using water/sediment mixtures or water alone from Tornoto Harbor, Canada(1). Butyltin compounds may be susceptible to biomethylation based upon the possible biomethylation of dibutyltin and tributyltin compounds(1).
Bioaccumulative potential
The observed BCF for dibutyltin dichloride in round crucian carp (Carassius carassius grandoculis) muscle, vertebra, liver, and kidney tissue were 12, 46, 135, and 61, respectively(2). In a tin bioconcentration study, the freshwater clam, Anodonta anatina, was exposed to dibutyltin dichloride for 7 months at a total concn of 15 ug tin equivalents/liter(2). Only total tin concn were determined(2). The average concn of tin in the gills, mantle plus mantle-edge, midgut gland, kidney, and remaining tissue fraction were as follows: 0.94, 0.13, 0.22, 0.60, 23.5, and 0.56 ug Sn/g wet wt, respectively(2). The max BCF for dibutyltin dichloride for the tissues are as follows (if all of the tin in the clams was in this form): 63, 8.6, 15, 40, 1,567, and 37, respectively(2). According to a classification scheme(2), a BCF value of 12 suggests bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Dibutyltin dichloride is expected to dissociate in water forming the cation, dibutyltin(SRC). Cations generally adsorb to organic carbon and clay(SRC). The adsorption of dibutyltin dichloride was studied under simulated estuarine conditions which included artificial seawater (salinity(S)), hydrous iron oxide (moderately particulate matter (PM)), and fulvic acid(1). The partition coefficients Kp (ug/kg)/ug/l) ranged from zero (no adsortion at pH 8.2 and with low S and high PM concn or high S and low PM concn) to 110,000 (at pH 6.2 and high S and low PM concn)(1). Based upon these results, dibutyltin dichloride is expected to exist mainly in the solution (aqueous) phase in estuarine waters and seawater(1). In a study of desorption from sediment, approximately 1% of the initial dibutyltin species was observed to desorb from the unshaken Toronto Harbor sediment/water mixtures in 10.6 months(2).

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.
