Abstract:
Buildup of agriculture pesticides in the aquatic habitat through natural run-off is a major problem faced by developing
and developed countries. The present study was designed to evaluate the 96 hr LC50 of herbicide, Pyrazosulfuron-Ethyl
which belongs to Sulfonylurea group. Using static bioassay with continuous aeration under laboratory conditions, acute
toxicity of the herbicide was determined for fresh water fish Oreochromis mossambicus. Hematological and
biochemical parameters are used as health indicators to detect the functional status of fish under acute exposure. Hence,
biochemical parameters like plasma glucose, protein, albumin and globulin were also studied to evaluate the toxic
potential of the herbicide. The herbicide led to significant changes in the hematological parameters such as RBC count,
Hb, PCV, MCH, MCHC, MCV and WBC count and biochemical parameters. These alterations can be used as non
specific biomarkers in herbicide contaminated aquatic ecosystem.
