A Survey on the Accumulation of Chromium in Plants near Various Tannery Industries of Vellore District, T.N.
Tannery industries have been a major source of chromium contamination in and around vellore district, Tamil Nadu, India, which has led to a serious environmental threat to the inhabitants. Our present study focuses on the investigation of accumulation and distribution of chromium in the root and shoot of Mimusops elengi; a commonly found plant in and around the vicinity of tannery industries. The plant samples including whole plant and rhizosphere soil were collected from various distances from the origin point of the industry. All the samples were acid digested and analyzed through Atomic Absorption Spectrophotometery (AAS-Model Varian C). The accumulation and distribution of chromium was detected and it was observed that the concentration of chromium was higher in the roots and shoots of plants growing at a distance of 250m and 500m which was quiet above the permissible limit.
