TABLE 5

Pond experiment with Leptophos (Phosvel) at 0.5 ppm initial dosage concentration. Pond stocked with Chanos (5–20 cm) and Tilapia (4–9.5 cm); small wild fish and shrimp present. Pond 200 m³, 0.35 cm depth. Leptophos (L), des-bromo-leptophos (DBL) and 4, bromo 2.5 dichloro phenol (BCL-P) concentrations in water, sediment, Chanos (alive), Tilapia (dead) and dead wild fish and shrimp. No mortality with Chanos.

Residue concentrations ECD equipment; oven 220°C. In ppb/wet, except for sediment in ppb/dry.
