Abstract	Potential toxic elements (PTEs) concentration was analyzed seasonally in seawater and sediment samples from Tuticorin coast, India. The extent of PTEs contamination in Tuticorin coast has been revealed by measuring the concentrations of iron (Fe), nickel (Ni), zinc (Zn), copper (Cu), cadmium (Cd), and lead (Pb) using inductively coupled plasma mass spectrophotometer (ICP-MS) seasonally. The concentration of all the PTEs in seawater samples was higher in summer and least in spring. The concentration of all the PTEs was significantly different within and among the season except for Zn and Cu. The concentration of PTEs in sediment samples was higher in winter and least in summer seasons. Exceptionally, the concentration of Cd was not significant among and within the seasons. The concentration of the PTEs in seawater and sediment samples exceeded the WHO-recommended limits. The contamination factor (CF) and geoaccumulation index (I $_{geo}$) values indicated significant contamination of PTEs in the sediment samples collected in different seasons. Variations in the concentration of PTEs could be due to changes in levels of pollution discharge over time, availability of PTEs for adsorption, as well as variations in the sampling season. The presence of a number of industries surrounding the Tuticorin coast and the release of the effluents from both industries and domestic sources are the main source of pollution at Tuticorin coast and are the prime reasons for the loss of existing diverse ecosystem.
