由于加德满都山谷消费的大部分鱼来自尼泊尔特莱地区的商业养殖场，有些来自印度，因此这些鱼的质量特性至关重要。因此，本研究的目的是提供加德满都山谷市场上9种商业鱼类肌肉中重金属浓度的信息，并使人们意识到与其消费相关的可能的健康风险。测定了猫（Catla catla）、鲳（Pampus species）、黄无须无须（Puntius chola）、瓦夏真热带鱼（Eutropiichthys vacha）、中国鲳（Pampus chinensis）、胡子鲶（Clarias batrachus）、野唇鱼（Labeo bata）、罗氏野唇鱼（Labeo rohita）和登加拉（Mystus tengara）肌肉中铅（Pb）、砷（As）、镉（Cd）、锌（Zn）、锰（Mn）和铬（Cr）的含量。采用加热消化器消化样品后，通过原子吸收分光光度法测定重金属水平。9种鱼类肌肉中重金属含量存在显著差异，没有一种鱼类肌肉中两种以上重金属含量最高。首先，发现了三种潜在有毒元素的最大平均浓度，铅在Chola中为16.75 μg/g，在Eutropiichthys vacha中为12.13 μg/g，在Catla catla中为11.63 μg/g;铅在Chola中为1.45 μg/g，在Pampus物种中为1.35 μg/g，在Mystus tengara中为1.15 μg/g。
Since the most of the fish consumed in the Kathmandu Valley are brought from commercial farms in the Terai region of Nepal and some from India, the quality characteristics of such fishes are foremost importance. Therefore, this study was carried out to provide the information on heavy metal concentrations in the muscles of nine commercial fish species available in the markets of Kathmandu Valley and to make people aware of the possible health risk associated with their consumption. The concentrations of Lead (Pb), Arsenic (As), Cadmium (Cd), Zinc (Zn), Manganese (Mn) and Chromium (Cr) were determined in the muscles of Catla catla, Pampus species, Puntius chola, Eutropiichthys vacha, Pampus chinensis, Clarias batrachus, Labeo bata, Labeo rohita and Mystus tengara. The levels of heavy metals were measured by atomic absorption spectrophotometry after digestion of the samples using the heating digester. There were significant variations among heavy metal levels in the muscles of the nine fish species, and no fish types had the highest levels of more than two metals. First, three maximum mean concentrations of potentially toxic elements were found 16.75 µg/g in Puntius chola, 12.13 µg/g in Eutropiichthys vacha , 11.63 µg/g in Catla catla for lead; 1.45 µg/g in Puntius chola , 1.35 µg/g in Pampus species and 1.15 µg/g in Mystus tengara for
