Abstract
The industries only provide the data of single chemical toxicity during the introduction of particular chemicals. But no one pesticide could survives alone in this nature; it would interact with other pesticides and exhibits their toxic nature more than individual. The previous reports of several research works have indicated that the synergistic interactions of various pesticides and heavy metals cause severe impact on the aquatic, terrestrial animals and as well as human beings when compared with their individual effects. In the current work the freshwater fish Labeo rohita were exposed to two toxicants Azoxystrobin, Copper sulfate individually and 1:1 ratio of their combine lethal toxicity synergistically. The estimated 24 hrs, 48 hrs, 72 hrs and 96 hrs LC50 values for Azoxystrobin were 5.7 mg/L, 4.9 mg/L, 4.1 mg/L, and 3.3 mg/L; Copper sulfate were 5 mg/L, 4.3 mg/L, 3.6 mg/L, and 2.9 mg/L; while the mixtures were 2.62 mg/L, 2.30 mg/L, 2.02 mg/L, and 1.75 mg/L, respectively. The data obtained were statistically evaluated using Finney’s probit analysis method and the survival time decreased with increasing concentration. The present study was undertaken is to provide an existing knowledge on the combine synergistic effects of pesticide and heavy metals in living systems.
