Metal contaminations in commercial fish have become a great public health concern worldwide including Bangladesh. The current study was conducted to provide preliminary evidence of nine metals in three commercially significant fish namely Pampus argenteus, Sardinella longiceps and Tenualosa ilisha collected from four coastal stations- Kuakata, Pathorghata, Cox's Bazar, and Pirojpur, and eight stations of five rivers- Padma, Meghna, Jamuna, Katcha, and Nobogonga in Bangladesh. High magnitudes of Pb (0.74–4.59 mg/kg ww), Cd (0.07−0.24 mg/kg ww), and Mn (0.45–2.03 mg/kg ww) were recorded in the sampling stations that exceeded the maximum permissible limits (MPL) proposed by different recognized organizations. Significant mean differences of metal concentrations were observed (p < 0.05) between species and stations. In fish samples, excessive metals accumulations were recorded from Kuakata (St.1) at the coastal area, and Nobogonga (St. 12) among the rivers. The health risk assessment (HRA) was carried out comprehensively via the estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI), and target cancer risk (TR) calculations. The outcomes of EDI, THQ, and HI suggest that chronic exposure to towering Pb content might pose potential health threats to inhabitants particularly living in highly polluted stations of the coastal area. In addition, the massive TR values of Cd intake through fish consumption from the coastal area might create cancer risks.

Accordingly, the ingestion of metals contaminated fish portends chronic as well as acute health risks to Bangladeshi people living both at home and abroad.

商业鱼类中的金属污染已成为全球包括孟加拉国在内的重大公共卫生问题。目前的研究旨在提供三种具有重要商业价值的鱼类（即Pampus argenteus、Sardinella longiceps和Tenualosa ilisha ）中的九种金属的初步证据。从四个沿海站 - Kuakata、Pathorghata、Cox's Bazar 和 Pirojpur 以及五个河流的八个站 - 孟加拉国的 Padma、Meghna、Jamuna、Katcha 和 Nobogonga 收集。在超过最大允许限值 (MPL) 的采样站中记录了大量的铅 (0.74–4.59 mg/kg ww)、Cd (0.07–0.24 mg/kg ww) 和 Mn (0.45–2.03 mg/kg ww) ) 由不同的认可组织提出。在物种和站点之间观察到金属浓度的显着平均差异 (p < 0.05)。在鱼类样本中，沿海地区的 Kuakata（St.1）和河流中的 Nobogonga（St.12）记录了过量的金属积累。健康风险评估（HRA）通过估计每日摄入量（EDI）、目标危害商数（THQ）、危害指数（HI）、和目标癌症风险 (TR) 计算。EDI、THQ 和 HI 的结果表明，长期接触高浓度铅可能对居民，尤其是生活在沿海地区高污染站点的居民构成潜在的健康威胁。此外，通过沿海地区的鱼类消费摄入大量 Cd 的 TR 值可能会产生癌症风险。

因此，摄入受金属污染的鱼类预示着生活在国内外的孟加拉国人面临慢性和急性健康风险。
