Heavy metals contamination of food is a serious threat. Long term exposure may lead to human health risks. Poultry and eggs are a major source of protein, but if contaminated by heavy metals, have the potential to lead to detrimental effects on human health.
The objective of this study is to determine chromium concentrations in poultry meat (flesh and liver) and eggs collected from poultry farms in Dhaka, Bangladesh, to calculate the daily intake of chromium from the consumption of poultry meat and eggs for adults, and to evaluate their potential health risk by calculating the target hazard quotients (THQ).
All samples of poultry feed, meat (flesh and liver) and eggs were analyzed by a graphite furnace atomic absorption spectrometer (AAS) (GFA- EX- 7i Shimadju, Japan).
Chromium concentrations were recorded in the range of not detected (ND) to 1.3926±0.0010 mg kg and 0.0678±0.0001 mg kg to 1.3764±0.0009 mg kg in the liver of broiler and layer chickens, respectively. Chromium concentrations were determined in the range of 0.069±1.0004 mgkg to 2.0746±0.0021 mg kg and 0.0362±0.0002 mg kg to 1.2752±0.0014 mg kg in the flesh of broiler and layer chicken, respectively. The mean concentration of chromium in eggs was 0.2174-1.08 mg kg. The highest concentration of chromium 2.4196±0.0019 mg kg was found in egg yolk. Target hazard quotients values in all poultry flesh, liver and eggs samples were less than one, indicating no potential health risks to consumers.
The estimated daily intake values of chromium were below the threshold limit. Thus, our results indicate that no adverse health effects are expected as a resultof ingestion of chicken fed with tannery waste.
This study was approved by the Biosafety, Biosecurity & Ethical Committee of Jahangirnagar University.
食品中的重金属污染是一个严重威胁。长期接触可能会给人类健康带来风险。家禽和蛋类是蛋白质的主要来源，但如果被重金属污染，就有可能对人类健康产生有害影响。
本研究的目的是测定从孟加拉国达卡的家禽养殖场采集的家禽肉（肌肉和肝脏）及蛋类中的铬浓度，计算成年人因食用家禽肉和蛋类而摄入铬的每日摄入量，并通过计算目标危害系数（THQ）来评估其潜在健康风险。
所有家禽饲料、肉（肌肉和肝脏）及蛋类样本均采用石墨炉原子吸收光谱仪（AAS）（日本岛津GFA-EX-7i）进行分析。
肉鸡和蛋鸡肝脏中的铬浓度记录范围分别为未检出（ND）至1.3926±0.0010毫克/千克和0.0678±0.0001毫克/千克至1.3764±0.0009毫克/千克。肉鸡和蛋鸡肌肉中的铬浓度测定范围分别为0.069±1.0004毫克/千克至2.0746±0.0021毫克/千克和0.0362±0.0002毫克/千克至1.2752±0.0014毫克/千克。蛋类中铬的平均浓度为0.2174 - 1.08毫克/千克。蛋黄中铬的最高浓度为2.4196±0.0019毫克/千克。所有家禽肉、肝脏和蛋类样本的目标危害系数值均小于1，表明对消费者没有潜在健康风险。
估计的铬每日摄入量值低于阈值。因此，我们的结果表明，食用用制革厂废料喂养的鸡肉不会产生不良健康影响。
本研究获得了贾汗吉尔纳加尔大学生物安全、生物安保与伦理委员会的批准。
