We examined and compared heavy metals bioaccumulation in and netted from Sardaryab, a tributary of River Kabul. By using atomic absorption spectrometry we assessed different organs including livers, gills, and muscles. Metals studied were chromium, iron, zinc, lead, and copper. Livers of both species showed higher concentrations of metals while muscles showed the least amount. Chromium and iron were the highly concentrated metals in the gills and livers of both species. A quantity of 0.154 ± 0.011, 0.199 ± 0.0079, and 0.024 ± 0.008 g/g of chromium was found in the gills, livers, and muscles of , respectively. Similarly, the gills, liver, and muscles of contained 0.133 ± 0.008, 0.165 ± 0.01, and 0.019 ± 0.006 g/g of Cr, respectively. Iron was highest in carp in the range of 0.086 ± 0.01 in gills and 0.067 ± 0.011 g/g in muscles, comparatively. All the studied metals were found within the US recommended daily dietary allowances (RDA) limits; hence no immediate risk in their consumption for human was found. The data showed that being omnivorous and bottom feeder stored higher concentrations of metals as compared to .
我们检测并比较了从喀布尔河支流萨尔达里亚布捕获的[两种鱼的名称未给出]体内重金属的生物累积情况。通过原子吸收光谱法，我们评估了包括肝脏、鳃和肌肉在内的不同器官。所研究的金属有铬、铁、锌、铅和铜。两种鱼的肝脏中金属浓度都较高，而肌肉中含量最少。铬和铁是两种鱼鳃和肝脏中浓度较高的金属。[第一种鱼的名称未给出]的鳃、肝脏和肌肉中铬的含量分别为0.154±0.011、0.199±0.0079和0.024±0.008克/克。同样，[第二种鱼的名称未给出]的鳃、肝脏和肌肉中铬的含量分别为0.133±0.008、0.165±0.01和0.019±0.006克/克。相对而言，鲤鱼鳃中铁含量最高，为0.086±0.01，肌肉中铁含量为0.067±0.011克/克。所有研究的金属含量均在美国推荐的每日膳食摄入量（RDA）限值范围内；因此，食用这些鱼对人类没有直接风险。数据表明，[第一种鱼的名称未给出]作为杂食性底栖动物，与[第二种鱼的名称未给出]相比，体内储存的金属浓度更高。
