12.2 Persistence and degradability

AEROBIC: Decarboxylation and N-acylation has been identified as cleavage reaction pathways for bifenox in soil(1). Biodegradation of bifenox has been shown to be limited to simple transformations such as the reduction of the nitro group with the most prominent metabolites being the corresponding anthranilic acid and nitrofen(2). Also observed when using C14-labelled compound, >60% of applied bifenox was found bound to the soil after 300 days(2). Bifenox exhibited a half-life of 3 to 7 days following preemergence application to a greenhouse soil; metabolites identified included 5-(2,4-dichlorophenoxy)-2-nitrobenzoic acid, nitrofen, and 5-(2,4-dichlorophenoxy) anthranilic acid over a 313-day period with an increase in the proportion of bound material(3). In non-flooded paddy soils, bifenox was degraded rapidly with a half-life of 6 days; the free acid was the main degradation product(4).

12.3 Bioaccumulative potential

An estimated BCF of 560 was calculated for bifenox(SRC), using a log Kow of 4.48(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). However, hydrolysis may attenuate this process(4). Radiolabeled bifenox, introduced to a model 33-day rice paddy ecosystem sand at a 1.29 kg/ha dosage, exhibited a comparatively low ecological magnification value of 49 in mosquito fish (Gambusia) as compared with the other rice paddy herbicides examined in this study, for example 1,546 for nitrofen and 867 formethoxy-nitrofen(4).

12.4 Mobility in soil

Kocs for bifenox have been reported ranging from 2,658 to 3,107(1). According to a classification scheme(2), these Koc values suggest that bifenox is expected to have slight to no mobility in soil. The sorption kinetics for bifenox were characterized by immediate rapid sorption with 30-70% of the added chemical adsorbed within the first 4 hrs, followed by a slow sorption over a longer time period(3). Slight desorption (10%) was noted after 24 hrs(3). In runoff experiments, it was shown that poorly soluble compounds like bifenox are only removed from fields as a result of heavy, erosive rainfalls on areas with a slope >10%; concn in soil before irrigation was 0.78 mg/kg in the 0-5 cm layer, after irrigation concns were in 0.77, 0.01, and 0.01 mg/kg at soil depths of 0-5, 5-10, and 10-15 cm, respectively(4).

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.
