Groundwater Contamination from a Municipal Landfill

Groundwater samples were collected seasonally and analysed for 28 physicochemical parameters; temperature, pH, electrical conductivity, dissolved oxygen, potassium, sodium, ammonium, calcium, magnesium, iron, manganese, cadmium, chromium, copper, lead, nickel, zinc, mercury, chloride, sulphate, bicarbonate, nitrate, nitrite, total nitrogen, total phosphorous, total organic carbon, polychlorinated biphenyls (PCB7) and polycyclic aromatic hydrocarbons (PAH16).

研究人员按季节采集地下水样本，并针对28项理化参数开展检测分析，涵盖温度、酸碱度（pH）、电导率、溶解氧、钾、钠、铵、钙、镁、铁、锰、镉、铬、铜、铅、镍、锌、汞、氯化物、硫酸盐、碳酸氢盐、硝酸盐、亚硝酸盐、总氮、总磷、总有机碳、多氯联苯（PCB7）以及多环芳烃（PAH16）。
