Assessment of Perchlorate Induced Acute Toxicity Study in Rasbora dandia

Divya P.S | Benno Pereira


Abstract: Perchlorate (ClO4-) is an emerging pollutant affecting aquatic ecosystem as well as human health and widely reporting from ground as well as surface waters near military sites and manufacturing units. As a pollutant, perchlorate requires utmost concern and its contamination report seeks global attention in the current world. Previous studies showed that in animals and plants perchlorate caused various toxic effects. The effect of perchlorate in an aquatic environment needs great concern due to the solubility, stability and persistent nature of perchlorate salts. The high water solubility and mobility in aquatic environment, perchlorate present in the soil can be transported into ground water and might remain for decades. Due to these properties aquatic organisms are most susceptible to perchlorate. In the present study we observed acute toxic effect of potassium perchlorate on a fresh water fish Rasbora dandia. Static bioassays were performed on Rasbora dandia to evaluate the median lethal concentrations of perchlorate for 24, 48, 72 and 96 hrs. The LC50 values of perchlorate to Rasbora dandia were 2011, 2007, 1987 and 1971 ppm after 24, 48, 72 and 96 hours respectively. The results showed that the LC50 values decreased with increase in concentration with exposure period.
