This paper aims to measure the metals (Fe, Cu, Cr, Co, As, Zn, Hg, and Pb) concentration and assesses human health risks posed by these eight metals in the five most available cultured fish species (Pangasiuspangasius, Oreochromisniloticus, Heteropneustesfossilis, Anabustestudineus, Clariasbatrachus) collected from the Mymenshing Sadar Upazila. Both fishes and three fish feeds were analyzed using energy dispersive X-ray fluorescence (EDXRF). In fish feeds, the concentrations of metals were detected in the following order Fe > Zn > Cu > Hg > Pb. Besides, Hg concentration in three feeds samples was found higher than the maximum residue limit. Fe, Cu, Cr, Co, As, Zn, Hg, and Pb concentration in fishes were 82.45 to 104.55, 24.47 to 32.88, 2.62 to 6.73, < 0.28, < 0.41, 70.01 to 96.56, 0.57 to 1.07, and 0.34 to 0.49 µg/g respectively as dry weight basis. Health Risk Index (HRI) was observed > 1 both for adults and children and maximum HRI values for Pb was found in both P. pangasius and C. batrachus fish species. Additionally, PCA explained 73% variation in data and CA comprised the similarity within sampling stations. Pearson correlation implied a strong association amongst the trace metals. Finally, the accumulation of metals tends to the massive health hazard that should be mitigated by adopting several measures on fish feeds.

本文旨在测量金属（铁，铜，铬，钴，砷，锌，汞，铅和铅）的浓度，并评估这五种最常见的养殖鱼类（Pangasiuspangasius，Oreochromisniloticus，Heteropneustesfossilis）中这八种金属构成的人类健康风险。，Anabustestudineus，Clariasbatrachus）收集自Mymenshing Sadar Upazila。使用能量色散X射线荧光（EDXRF）分析了鱼类和三种鱼类饲料。在鱼饲料中，金属的浓度按以下顺序检测：Fe> Zn> Cu> Hg> Pb。此外，发现三份饲料样品中的汞浓度高于最大残留限量。鱼中的Fe，Cu，Cr，Co，As，Zn，Hg和Pb的浓度分别为82.45至104.55、24.47至32.88、2.62至6.73，<0.28，<0.41、70.01至96.56、0.57至1.07和0.34至0.49以干重计分别为µg / g。健康风险指数（HRI）中观察到> 1都为成人和儿童和铅最大HRI值都被发现P.鲶和C.蟾鱼种。另外，PCA解释了数据中73％的变化，CA包含了采样站之间的相似性。皮尔逊相关性暗示痕量金属之间的强关联。最后，金属的积累趋于造成巨大的健康危害，应通过对鱼类饲料采取多种措施来减轻这种危害。
