坎普尔市有大量的小规模工业（SSI），主要包括纺织和皮革工业。本研究清点了从坎普尔市Panki和Jajmau工业区收集的样品中重金属的存在。固体废物样品中重金属的总浓度分别为Fe 1885和2340 mg/kg、Mn 173和445 mg/kg、Zn 233和132 mg/kg、Cu 20和28 mg/kg、Cd 1.4和1.1 mg/kg、Ni 26和397 mg/kg、Pb 107和19 mg/kg、Cr 1323和734 mg/kg。土壤和道路灰尘样品中的重金属浓度也很高，即镍和铅在少数样品中的浓度较高，而铬在所有样品中的浓度均高于美国环保局的建议值和印度城市固体废物（管理和处理）规则（2000年）中所载的堆肥质量规格。检测到的重金属污染表明地下水、地表水和食物链受到污染。这引起了对环境和人类健康不利后果的关注。
Kanpur city has large number of small-scale industries (SSIs), primarily comprising of textile and leather industries. This study inventorises the presence of heavy metals in the samples collected from Panki and Jajmau Industrial Areas of Kanpur city. The bulk concentration of heavy metals found in solid waste samples was Fe as 1885 and 2340mg/kg, Mn 173 and 445mg/kg, Zn 233 and 132mg/kg, Cu 20 and 28mg/kg, Cd 1.4 and 1.1mg/kg, Ni 26 and 397mg/kg, Pb 107 and 19mg/kg, Cr 1323 and 734mg/kg, respectively. Heavy metal concentration was also found to be high in soil and road dust samples viz. Ni and Pb were in higher concentration in few samples, whereas Cr was found in higher concentration in all samples than the recommended values of USEPA and specifications for compost quality contained in the Indian Municipal Solid Wastes (Management and Handling) Rules, 2000. The heavy metal pollution so detected is indicative of contamination in ground and surface water and food chain. This raises concerns pertaining to adverse consequences to environment and human health.
