Received: 13 Apr 2019/ Revised: 21 Jul 2019/ Accepted: 16 Aug 2019 ABSTRACT Background: The rapid industrialization of the coastal areas has resulted in marine pollution in different regions of the Southeast coast of India. The quality of coastal and marine water affected by the toxic pollutants released from the industrial activities and urbanization has been assessed in terms of pollution. The present study area also referred that the industrial activity is more responsible for marine pollution, causing toxic effects by heavy metals. Methods: For the present study water samples collected from Nelaturu, Krishnapatnam coastal villages of Nellore and samples brought to the laboratory for heavy metals analysis by Atomic Absorption Spectroscopy (AAS) standard methods followed by American Public Health Association (APHA). Results: During the present study the heavy metals Arsenic, Lead, Cadmium, Mercury, Iron, Manganese, Copper, Zinc concentrations were observed, shown in Table 1 and discussed the levels when compared with water quality standards given by the Indian Standards (IS: 10500) and WHO guidelines. Conclusion: The present study sites are one of the famous places for marine fishing area having near thermal power plants and port activities. In our study, there were eight heavy metals were determined, which were observed in 2 sampling sites i.e. Nelaturu, Krishnapatnam in Nellore district. The study had been concluded with the future impact of heavy metals in the marine environment and to the aquatic life as well as to human life at Nellore coast.
