Persistence and degradability
Bentazon can be rapidly utilized by bacteria and fungi(1). Bentazon was degraded in 8 soils with half-lives ranging from 6.7 to 15 days, and 38 to 50 days, for soils with and without a history of bentazon application, respectively(2), which suggests acclimation(SRC). In aerobic soil incubation experiments, approximately 80% of the initial bentazon applied remained after 28 days in sandy clay loam soil, in clay soil there was no significant conversion of bentazon after 30 days incubation(3). The aerobic half-life in freshly collected field soils ranged from 11 to 14 days(4,5). The average half-life of bentazon in laboratory soils was about 46 days(4,5).
Bioaccumulative potential
An estimated BCF of 79 was calculated for bentazon(SRC), using an experimental log Kow of 2.8(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate.
Mobility in soil
Soil adsorption coefficient: 0 (Experimental); 140 (Calculated). From table
Other adverse effects
no data available
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.
