Fifty four sediment samples representing pre and post-monsoon seasons were collected along a transect from off Kochi, lying between the latitudes 9°57'59.5″-9°54'30.4″ and longitudes 76°11'7.04″-75°38'50.3″ of the South eastern Arabian Sea. The present study investigates the levels of trace metals (Zn, Cd, Pb, Cu, Fe, Ni, Mn, Co and Cr), total organic carbon (TOC), total inorganic carbon (TIC), elemental composition and grain size to assess the extent of environmental pollution and to discuss the distribution of these trace metals in the surficial sediments. Sediment pollution assessment was done using the Contamination factor (C.F), Geoaccumulation Index (Igeo), Enrichment Factor (EF), and Pollution Load Index (PLI). The majority of trace metals analysed in this study exhibited the highest concentrations at stations 1, 2 and 3 where the land-based anthropogenic input was found to be maximum.
从科钦（Kochi）附近沿着一条位于南阿拉伯海（South eastern Arabian Sea）的 9°57'59.5″-9°54'30.4″ 和 76°11'7.04″-75°38'50.3″之间的纬度和经度的测线采集了 54 个沉积物样本，分别代表前季风季和后季风季。本研究调查了痕量金属（Zn、Cd、Pb、Cu、Fe、Ni、Mn、Co 和 Cr）、总有机碳（TOC）、总无机碳（TIC）、元素组成和粒度的水平，以评估环境污染的程度，并讨论这些痕量金属在表层沉积物中的分布。使用污染因子（C.F）、地质累积指数（Igeo）、富集因子（EF）和污染负荷指数（PLI）对沉积物污染进行了评估。本研究分析的大多数痕量金属在站点 1、2 和 3 处表现出最高浓度，在这些地方发现了最大的陆地人为输入。
