This study investigated the concentrations of potentially toxic elements (PTE) including copper (Cu), chromium (Cr), cobalt (Co), cadmium (Cd), nickel (Ni), iron (Fe), zinc (Zn), lead (Pb), molybdenum (Mo) and manganese (Mn) in water and soil of the Chitral city, Pakistan. For this purpose, water (n = 66) and soil (n = 48) samples were collected from various locations of the Chitral city and analyzed for the PTE concentrations. Determined PTE concentrations were evaluated for the human and ecological potential risk. Results revealed that hazard quotient through water consumption was less than the threshold limit (1). However, for soil, the Fe mean hazard index (HI > 1) value for children only surpassed the threshold limits. The mean cancer risk index values via soil exposure were higher (RI > 1 × 10^–4) through consumption of Co, Ni and Cd for children and only Co for adults. Contamination factor (CF) values for Mo, Cd and Fe were found very high, considerable and moderate for 79%, 8% and 77% of sampling sites, respectively. Geoaccumulation index (I_geo) showed that soils were moderately–heavily polluted due to Mo. Potential ecological risk index (PERI) values exhibited considerable risk with an average risk index value in the range 190 < RI < 380. Higher values of CF, I_geo and PERI revealed the presence of pollution and pose risk to ecological environment.

这项研究调查了潜在毒性元素（PTE）的浓度，包括铜（Cu），铬（Cr），钴（Co），镉（Cd），镍（Ni），铁（Fe），锌（Zn），铅（巴基斯坦奇特拉尔市的水和土壤中的钼（Mo）和锰（Mn）。为此，水（n  = 66）和土壤（n = 48）从Chitral城市的各个位置收集了样本，并分析了PTE浓度。对确定的PTE浓度进行了人类和生态潜在风险评估。结果表明，通过耗水量得出的危害商数小于阈值极限（1）。但是，对于土壤，儿童的平均Fe危害指数（HI> 1）值仅超过阈值限制。通过摄入儿童中的Co，Ni和Cd以及仅成人中的Co，通过土壤暴露获得的平均癌症风险指数值更高（RI> 1×10 ^–4）。分别有79％，8％和77％的采样点发现Mo，Cd和Fe的污染因子（CF）值非常高，相当大和中等。地质累积指数（我_地理）表明土壤由于钼而受到了中度至重度污染。潜在的生态风险指数（PERI）值表现出相当大的风险，平均风险指数值在190 <RI <380范围内。较高的CF，I _geo和PERI值表明存在污染并对生态环境构成风险。
