Eighty-three surface sediments were collected to investigate the element concentration based sediment pollution and potential ecological risk status of the Pulicat lagoon, southeast coast of India. The textural characteristics, Fe and Mn concentration in the surface sediments are chiefly controlled by the confluence of riverine inputs and vicinity of the marine environment. The varied distribution of CaCO concentration is due to the depth of the lagoon followed by the sand and silty sand characteristics of the substratum. The surface sediments are derived from riverine sources. Sediment Pollution Index (SPI), Potential Ecological Risk Index of the sediments suggests that they are falling under less polluted and low potential ecological risk category.
采集了 83 个表层沉积物，以调查印度东南海岸的普利卡特泻湖的元素浓度为基础的沉积物污染和潜在生态风险状况。表层沉积物的质地特征和 Fe、Mn 浓度主要受河流输入的汇合和海洋环境的临近影响。CaCO3 浓度的不同分布是由于泻湖的深度以及基底的沙质和粉砂质特征所致。表层沉积物来源于河流。沉积物污染指数（SPI）和沉积物的潜在生态风险指数表明，它们属于污染较轻和潜在生态风险较低的类别。
