12.2 Persistence and degradability
AEROBIC: Butralin is degraded by soil microflora such as Paecilomyces sp; the major biodegradation product is 4-tert butyl 2,6 dinitroanaline(1). 14C-labeled butralin, applied at a concentration of 10 ppm to Chillum silt loam soil incubated at 70% field moisture capacity, was 57% degraded after 6 months; 98% applied 14C was recovered after 2 months(2). Under greenhouse conditions, butralin exhibited half-lives ranging from 21-52 days, with a mean half-life of 40 days(3). Using a Sharkey clay (4% sand, 25% silt, 71% clay, 4.2% organic matter) and Bosket clay loam (20% sand, 60% silt, 20% clay, 1.5% organic matter) soils in greenhouse experiments, butralin, applied at 8 umole/kg to 2,000 g soil, exhibited half-lives of 52 and 29 days, respectively(3).
12.3 Bioaccumulative potential
An estimated BCF of 1248 was calculated for butralin(SRC), using a log Kow of 4.93(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC).
12.4 Mobility in soil
The Koc of butralin has been reported as 3,400(1). According to a classification scheme(2), this Koc value suggests that butralin is expected to have slight mobility in soil. Butralin was strongly adsorbed by organic matter, as shown by 77, 82, and 78% adsorption of addition of 2.5, 5.0, and 10X10-6 M concentrations, respectively(3). The same concentrations added to montmorillonite resulted in 21, 13, and 9% adsorption, respectively(3). Subsequent desorption studies showed very little desorption from organic matter by either water or 1 N CaCl solution, results being 13.2 and 11.1%, respectively; 91.7 and 68.4% desorption, respectively, was desorbed from montmorillonite(3). Metapeake loam, treated 7 months earlier with 10 ppm butralin, contained 27% nonextractable radioactivity(1).
12.5 Other adverse effects
no data available
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.
