The fate of carbosulfan in rice [Oryza sativa] paddy ecosystem (Philippines)
1984
Tejada, A.W. | Magallona, E.D.
The extent of pollution of carbosulfan was monitored from the rice paddy into the fish pond. Carbofuran was the major residue detected. The concentration in water was biomagnified in fish (Tilapia nilotica) about 300-400 times. The highest concentration was found in entrails, then in fillet and least in head. Ipomoea aquatica, an aquatic plant, accumulated residues up to 15 days, declining thereafter. Residues were in the shell of the snail, Pila luzonica. The residue was highest in plants, then in water and soil, fish and snails and air. In all cases, the mechanism of loss followed pseudo first order kinetics with the longest half life value in fish, i.e. 10.6, 13.6 and 17.3 days in fillet, head and entrails, respectively
