Acute and Chronic Toxicity of Fluoride and Aluminum on Plant and Animal Models
Abstract: Ecotoxicological studies revealed aluminum (Al2SO4. 24 H2O) to be more toxic than fluoride (NaF) on a battery of test organisms (EC/LC50 of Al = 0.308 1.46 ppm; F = 116.6 232.8 ppm). During chronic exposure (Al = 3 ppm, F = 10 ppm for 60 90 days), there was reduction in growth parameters of organisms at different trophic levels in a food chain such as producers {dry weights (6.7 29.0) …

Mercury-induced Biochemical Changes in Perna viridis Exposed in Chronic Toxicity Test
Abstract: In the present study, the Asian green mussel, Perna viridis, was exposed to 50, 75, 113, 160 and 253 µg/L Hg concentrations under chronic toxicity for the assessment of biochemical biomarkers. Higher levels of glutathione S-transferase (GST), reduced glutathione (GSH), lipid peroxidation (LPO) and lower levels of protein, catalase (CAT) and acetylcholinesterase (AchE) were found. The values were found to be significant at P < 0.01. This study suggests that …

Role of Models in Predicting Toxicity Criteria against Arsenic Toxicity Test Exposed to Therapon Jarbua (Forsskal, 1775)
Abstract: Prediction of safe concentration, no-effect concentration for reduced animal usage in chronic toxicity test was attempted as well as to create a toxicity criteria limit for arsenic using Therapon jarbua in static renewal acute toxicity test. The LC50 value derived was 3.95 (3.43–4.58) mg/L arsenic. The derived LC50 was applied for prediction of safe concentration leading to a value of 39.5 µg/L. The raw survival and mortality data was fed …
