Accumulation of Fluoride from Natural Water Sources in Oreochromis mossambicus (Peters, 1852)
Journal Title: Scholars Academic Journal of Biosciences - Year 2014, Vol 2, Issue 9
Abstract
O. mossambicus (Tilapia) samples from five study sites Ernakulam, Alappuzha town, Mannancherry, Ambalappuzha and Kuttanad were analyzed for the fluoride content. The water from which the fishes were collected was also analyzed for the content of fluoride. Although all water samples showed fluoride concentration below the WHO 1984 maximum permissible limit for drinking water of 1.5ppm, considerable amount of fluoride were found to be accumulated in the fish samples and a positive correlation (0.75) was observed between the fluoride concentration in water and the corresponding fish samples. Water samples from Ambalappuzha had the highest fluoride concentration of 0.4±0.01mg/L. Correspondingly the Tilapia samples from the same water body had the highest fluoride content of 174.3±0.47mg/Kg. The lowest content was found in water and tilapia samples from Alappuzha town, 0.05±0.01mg/L and 18.14±0.95mg/Kg respectively.
