| The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30 surface sediments were measured using Atomic Absorption Spectrometer to investigate the spatial and seasonal variations of trace metals along Kanyakumari coast, India. To assess the environmental risk of trace metals, enrichment factor, geo-accumulation index, pollution load index, and ecological risk index have been calculated. According to the pollution load index and geo-accumulation index (Igeo) values, Kanyakumari coastal sediments were unpolluted by Fe, Cu, Pb, and Zn, whereas moderately polluted by Cd with low to moderate ecological risk. The existence of the high hydrodynamic condition during the southwest monsoon is more favorable to the transport of sediments and enhance the accumulation of metals, whereas during the northeast monsoon the accumulation of metals is less. The baseline data for spatial distribution and seasonal variation of trace metals and their controlling factors found in this study will be useful for pollution monitoring program along the Kanyakumari coast. | ||
