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) …
