AEROBIC: In soil, chlormequat chloride is rapidly degraded by microbial activity and has no influence on soil microflora or fauna(1). Half-lives in 4 soils were reported as averaging 32 days at 10°C and 1 to 28 days at 22°C(1). Studies with soil microorganisms indicated that chlormequat chloride breakdown occurred through oxidative processes(2). Chlormequat chloride, at an initial concentration of 282 ppm, biodegraded 18% after running a compost operation consisting of poultry and pig manure for 56 days; the high concentration may have retarded degradation(3). Based on analogy to other quaternary ammonium compounds(4), the reduction of biomass or other nutrient materials in natural water may reduce the biodegradation rate of the chlormequat chloride cation and acclimation enhances biodegradation of quaternary ammonium compounds.
12.3 Bioaccumulative potentialAn estimated BCF of 3.2 was calculated for chlormequat chloride(SRC), using a log Kow of -3.80(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilThe Koc of chlormequat chloride has been reported to be 203(1). According to a classification scheme(2), this Koc value suggests that chlormequat chloride is expected to have moderate mobility in soil. However, this compound exists as a quaternary ammonium cation and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(3). Chlormequat chloride is expected to adsorb strongly to various materials, including suspended solids in wastewater treatment facilities, sediments in rivers and lakes, suspended organics and minerals in natural water systems, clays, proteins, and microorganisms(4-6). Further, adsorption of quaternary ammonium compounds to river sediment occurs primarily by an ion-exchange mechanism(5). Monitoring studies of river water samples from Germany reported that 50% of an alkyltrimethyl quaternary ammonium compound detectable in the water column was associated with suspended solids in the water; the suspended solids in the water comprise a small fraction of the water(7).
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.
