In this data, the heavy metal concentration and magnetic susceptibility in coastal sediment samples collected from Periyakalapet to Parangaipettai of East Coast of Tamilnadu using Energy Dispersive X-ray Fluorescence (EDXRF) technique and dual frequency susceptibility meter. We aimed to (i) determine the heavy metal concentration in the sediments from Periyakalapet to Parangaipettai of East Coast of Tamilnadu (ii) assess the magnetic mineral property of sediments (iii) study the correlation between heavy metal and magnetic susceptibility. The determined heavy metal concentration found in the order of Mn> Ba > V > Cr > Zn > La > Ni >Pb> Co > As > Cd > Cu > Al > Fe >Ca> Ti > K > Mg. The magnetic susceptibility (χ) measurements show that they vary from 5.92×10 m kgto 29.06×10 m kg with an average of 20.39×10 m kg. Analysed data confirmed that magnetic susceptibility has the potential tool to indicate the heavy metal pollution sources.
在这些数据中，使用能量色散X射线荧光（EDXRF）技术和双频磁化率仪，对从泰米尔纳德邦东海岸的佩里亚卡拉佩特到帕兰盖佩泰采集的沿海沉积物样本中的重金属浓度和磁化率进行了测定。我们旨在：（i）确定泰米尔纳德邦东海岸从佩里亚卡拉佩特到帕兰盖佩泰沉积物中的重金属浓度；（ii）评估沉积物的磁性矿物特性；（iii）研究重金属与磁化率之间的相关性。所测定的重金属浓度顺序为：锰>钡>钒>铬>锌>镧>镍>铅>钴>砷>镉>铜>铝>铁>钙>钛>钾>镁。磁化率（χ）测量结果表明，其范围为5.92×10⁻⁶ m³ kg⁻¹至29.06×10⁻⁶ m³ kg⁻¹，平均为20.39×10⁻⁶ m³ kg⁻¹。分析数据证实，磁化率是指示重金属污染源的潜在工具。
