Acute Toxicity of Detrergent ‘Tide’ In the Snail, Bellamya Bengalensis (Lamarck)

P. Raghava Kumari

Abstract :

Acute toxicity studies were carried out in the freshwater snail (Bellamya bengalensis) exposed to sub-lethal concentrations of detergent Tide. Mortality was assessed and concentrations (LC50) were calculated. LC50 increased with the decrease in mean exposure concentrations and times, respectively. The LC50 values obtained with the snails exposed to detergent (Tide) are 213.7 ppm for 24 hrs, 134.896 ppm for 48 hrs, 104.71 ppm for 72 hrs and 69.18 ppm for 96 hrs. The effects of sub-lethal concentrations of Tide on histology of foot and digestive gland have been studied in detail. The exposure of the snails to sub-lethal concentrations of the detergent caused desquamation of the epithelial cells, disruption of glandular cells and atrophy of the columnar muscle fies in the foot, disintegration of basement memane, disruption of hepatic tubules, and occurrence of cell deis in between the tissue in digestive gland at 69.18 ppm for 96 hrs.
