12.2 Persistence and degradability
AEROBIC: In soil, vernolate undergoes microbial decomposition to mercaptan, amine, carbon dioxide, and isopropanol(1). The half-life of vernolate in clay soil is 10-12 days(1). Vernolate has a short residual in soil with a typical field half-life of 12 days(2). The half-life in moist loam soil at 21-27°C was approximately 1.5 weeks(2). In sandy loam soil, the first and second aerobic soil half-lives were 40 days and 139 days(3). The half-life of vernolate (5 ppm) was 2-3 weeks both in Regina heavy clay (pH 7.5, 4.0% organic content) and Weyburn loam (pH 7.0, 6.5% organic content) at 25°C with water added to field capacity(4). Vernolate (1280 ppm) was 60% detoxified in 8 weeks at the optimal soil pH of 7.6 as determined by cucumber bioassays(5). Repeated vernolate use on a plot of soil resulted in enhanced degradation where adapted organisms degrade the pesticide faster(6).
12.3 Bioaccumulative potential
An estimated BCF of 180 was calculated for vernolate(SRC), using a log Kow of 3.84(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC).
12.4 Mobility in soil
Vernolate is adsorbed onto dry soil(1). An average Koc of 260 has been measured(1). The Koc values in 6 Hungarian soils (sandy loam, loam, and clay) ranged from 83 to 391(2). Measured Koc values of 259(3) and 214(4) have also been reported. According to a classification scheme(5), these Koc values suggest that vernolate is expected to have moderate to high mobility in soil. The leaching of vernolate incorporated in the upper 2 inch layer of soil was determined in 5 soils of widely different soil types having organic carbon contents ranging from 0.46 to 20.1% after two applications of 4 inches of water(6). Vernolate leached as far as the 6-9 inch layer in sandy loam (0.46% OC) and loamy sand (2.7% OC) soils, as far as the 3-6 inch layer in loam (3.2% OC) and clay (6.7% OC), and as far as the 0-3 inch layer in a peat soil (20.1% OC)(6). Leaching decreased with the clay content, as well as the organic carbon content of the soil(6).
12.5 Other adverse effects

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.
