12.2 Persistence and degradability
The effects of some potential chemical, photochemical, biological and environmental conditions upon the degradation of fenthion in laboratory and field experiments were investigated. The effects of biological activity on the degradation of fenthion were examined with mangrove swamp water in a dark bottle. Photolytic degradation was observed with mangrove water that was sterilized by the addition of mercuric chloride to 40 ppm and exposed to natural sunlight for the field study. Different natural waters (ocean, inlet, estuarine, mangrove swamp, freshwater lake, and canal) were collected and incubated in the pond for studying the fenthion disappearance rate in different types of water bodies. The stability of fenthion under acidic and alkaline conditions was observed for hydrolytic degradation. A comparison of the biological degradation by aquatic microorganisms against that of chemical degradation by pH adjustment was also investigated. The results show that fenthion remains relatively stable under acidic to neutral conditions. Under alkaline conditions fenthion still remains stable up to pH 11. Higher salinity resulted in a shorter half-life. Fenthion was found to be susceptible to biological degradation by anaerobic or non-photolytic organisms. In natural waters, the degradation of fenthion was related to the biological activity of each water sample. Mangrove water exhibited the lowest half-life (2.9 days) while the ocean water showed the longest half-life (21.1 days).
12.3 Bioaccumulative potential
Using a flow-through system and up to 11 days of exposure, a mean BCF of 16,600 (extractable lipid basis) was measured in guppies (Poecilia reticulata)(1). Based upon a measured Log Kow of 4.09(2) and a water solubility of 7.5 mg/l at 20 deg C(3), the BCF of fenthion can be estimated to be 760 and 200, respectively, from regression derived equations(4,SRC). These measured and estimated BCF values suggest that bioconcentration in aquatic organisms may have some environmental importance(SRC). A fenthion BCF of 62 was measured in tadpoles after a 96 hr exposure period in a flow-through system(5).
12.4 Mobility in soil
Based upon a measured log Kow of 4.09(1) and a water solubility of 7.5 mg/l at 20 deg C(2), the Koc of fenthion can be estimated to be 4000 and 1400, respectively, from regression derived equations(3,SRC). The US Dept Agric's Pesticide Properties Database lists a Koc value of 1500 for fenthion(4). According to a suggested classification scheme(5), these estimated Koc values suggest that fenthion is only slightly mobile in soil(SRC).
12.5 Other adverse effects
no data available
SECTION 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.
