Individual and combined toxicity of common pesticides to teleost Puntius conchonius Hamilton.

Individual and combined toxicity of three pesticides, endosulfan, phosphamidon, and aldicarb was evaluated in P. conchonius. The 48 hr LC50 was 21.36 and 446.5 ppm respectively for endosulfan and phosphamidon. When tested jointly, 48 hr LC50 for different ratios of these pesticides were 0.332 (IE:3P), 0.224 (IE:1P), and 0.178 ppm (3E:1P). The cotoxicity coefficients for these combinations were 1793, 3986, and 10009, respectively. An equitoxic mixture of endosulfan, phosphamidon, and aldicarb yielded a 48 hr LC50 of 130.5 ppm. An enhanced toxic impact is indicated when the pesticides are present together rather than as individual compounds.
