Environmental Fate and Toxicity
Carboxin's toxicity to birds is very low (Table 57.2). In 8-day feeding studies with birds, the LC50 was greater than >4640 ppm in the feed with mallard ducks and > 10,000 ppm with bobwhite quail. Carboxin has a low acute toxicity to aquatic species including fish and invertebrates such as Daphnia (Table 57.2) and juvenile crayfish (LC50 of 217 ppm). A bioconcentration factor of 34 has been calculated for carboxin which suggests little risk of accumulation by aquatic species.
Carboxin is converted to its sulfoxide in vivo and in water and soils, but further oxidation to the sulfone (oxycarboxin, see below) is extremely slow. Carboxin's half-life in soils is 1-3 days (Balasubramanya and Patil, 1980; Chin et al., 1970, Wauchope et al., 1992). The range of Koc values (80-259) indicates a medium to high mobility in soil and significant leaching is observed in laboratory tests (U.S. EPA, 1989a).
