Heavy metals in some environmental samples around a few industrial locations of tuticorin coast

摘要

Due to rapid industrialization and urbanization, our environment has been polluted by toxic metals, inorganic salts, pesticides, etc., through the discharge of industrial and sewage effluents. The present study monitored some heavy metals in the ambient environment of selected industrial and sewage effluents discharge locations around Tuticorin Coast, Gulf of Mannar, India. Samples of water, sediment, soil, and plant, (both aquatic and terrestrial), were collected in and around some industrial sites. A relatively less polluted area near Mandapam was selected as control site. The concentration of the metals varied depending upon the Industrial effluent. The overall study indicated that, among all the metal the concentration of lead was relatively high and zinc was low in collected samples, because lead compound has been used in a wide variety of Industrial application.
