Phosphatase Activity and Heavy Metal Distribution in Soils of Vellore, India

A b s t r a c t K e y w o r d s The present work reports the biogeochemical analysis of the soil quality in Vellore which is considered as industrial hotspot of Tamil Nadu, India. The industrial area dominates with leather industries and is highly contaminated with heavy metals. In this study, the enzyme activities and other important physico-chemical properties were estimated in specific locations of the in and around the city. The work also gives an estimate of using enzyme activities as an important indicator of soil quality. The data indicates that the phosphorus in the soil was unavailable for microorganisms due to presence of very high concentrations of heavy metals, which was observed indirectly from low microbial biomass and high bioavailable phosphorus.
