This study aimed to investigate the heavy metal contamination in poultry meat of Kotli Sattian, Rawalpindi. The meat samples from ten sites were analyzed for lead, cadmium, chromium, copper, arsenic, nickel, zinc, iron, sodium, and calcium. The possible health risks of these metals were also observed. Mean lead, cadmium, chromium, arsenic, and nickel concentrations were higher than the permissible limits of the World Health Organization (WHO). Metals in meat samples showed the trend of Fe > Na > Zn > Ni > Ca > As > Cr > Pb > Cu > Cd. All the studied metals except lead were statistically significant (P ≤ 0.05). The hazard quotient (HQ) values of all the metals were below one, except iron. Iron showed chronic health risks in both adults (1.63) and children (3.64). Moreover, the cumulative hazard index (HI) of the metals indicated that meat consumption can pose a significant chronic toxic risk in both adults and children as the HI value was 2.06 for adults and 4.61 for children, which is greater than one. The carcinogenic risk (CR) of arsenic in meat for adults and children exceeded the acceptable range, making it a metal of concern. This means that the consumption of small concentrations of metal through meat may be the source of severe toxicological consequences. It can be concluded that meat is contaminated with metals; therefore, appropriate precautions should be taken to minimize this contamination.
本研究旨在调查拉瓦尔品第科特利·萨蒂安家禽肉中的重金属污染情况。对来自十个地点的肉样进行了铅、镉、铬、铜、砷、镍、锌、铁、钠和钙的分析。还观察了这些金属可能带来的健康风险。铅、镉、铬、砷和镍的平均浓度高于世界卫生组织（WHO）的允许限值。肉样中的金属呈现出Fe＞Na＞Zn＞Ni＞Ca＞As＞Cr＞Pb＞Cu＞Cd的趋势。除铅外，所有研究的金属在统计学上均具有显著性（P≤0.05）。除铁外，所有金属的危害商（HQ）值均低于1。铁对成年人（1.63）和儿童（3.64）均显示出慢性健康风险。此外，金属的累积危害指数（HI）表明，食用肉类对成年人和儿童均可能构成显著的慢性毒性风险，因为成年人的HI值为2.06，儿童为4.61，均大于1。肉中砷对成年人和儿童的致癌风险（CR）超出了可接受范围，使其成为一种值得关注的金属。这意味着通过肉类摄入低浓度的金属可能是严重毒理学后果的来源。可以得出结论，肉类受到金属污染；因此，应采取适当预防措施以尽量减少这种污染。
