Analysis of Heavy Metals Accumulation in Nagapattinam Coastal Waters, South East Coast of India

Abstract

Heavy metals in ocean water which cause hazardous impact to the marine organisms. Effluent discharges from industries such as metal processing, paints and pigment production, and biocides production and through domestic sewage from nearby villages. Toxic metals such as cadmium (Cd), Cr, copper (Cu), mercury (Hg), and zinc (Zn) emanate from these industries polluting seawater and paving the way for the many serious problems we face today. The current study focuses on the distribution of heavy metals between October 2016 and March 2017 in coastal waters in Tranquebar, Poraiyar, Kottucherry, and Karaikal, off the southeast coast of India. Four metals including Cd, Cu, Hg, and Zn were analyzed by a microwave assisted digestion and the atomic absorption spectrophotometer. These comments and subsequent considerations of this study help to manage the impact of pollution from wild and industrial sources into aquatic environments. Hence, the coastal regions needed throughout impoundment.
