This data article aimed to investigate the quality of surface water in Kalingarayan Canal for heavy metal pollution, Tamil Nadu. Eight heavy metals like Fe, Cu, Mn, Cr, Zn, Cd, Pb, and Ni were analyzed in the water, for a period of three years, spanning the time frame between January 2014 to December 2016. Eight stations were selected along the Kalingarayan Canal, and water samples were collected on a monthly basis from these stations. The pH of the samples was in the alkaline state (6.88-8.90), whereas conductance was in the range of 394-4276 µs/cm. The average concentration of heavy metals in the surface water ranges from 0.040 to 10.75, 0.030 to 0.890, 0.02 to 0.91, 0.00 to 1.96, 0.00 to 0.01, 0.00 to 0.053, 0.01 to 0.12 and 0.110 to 3.40 mg/L for the metals Fe, Mn, Zn, Cu, Cd, Ni, Pb and Cr respectively. The dominance of various heavy metals in the surface water follows the sequence: Fe > Cr > Cu > Zn > Mn > Pb > Ni > Cd respectively. The canal is affected by anthropogenic activities and industrialization in terms of heavy metals.
本数据文章旨在调查泰米尔纳德邦卡林加赖扬运河地表水的重金属污染质量。对铁、铜、锰、铬、锌、镉、铅和镍这八种重金属在2014年1月至2016年12月的三年时间内进行了水体分析。沿着卡林加赖扬运河选择了八个站点，每月从这些站点采集水样。样品的pH值呈碱性（6.88 - 8.90），而电导率范围为394 - 4276µs/cm。地表水重金属的平均浓度分别为：铁0.040至10.75mg/L、锰0.030至0.890mg/L、锌0.02至0.91mg/L、铜0.00至1.96mg/L、镉0.00至0.01mg/L、镍0.00至0.053mg/L、铅0.01至0.12mg/L、铬0.110至3.40mg/L。地表水各种重金属的优势顺序分别为：铁>铬>铜>锌>锰>铅>镍>镉。就重金属而言，该运河受到人为活动和工业化的影响。
