Abstract:
قرار گرفتن در معرض فلزات سنگین از طریق مصرف پرندگان ممکن است منجر به خطر سلامتی برای افراد به ویژه در مناطقی که فعالیت-های کشاورزی و صنعتی وجود دارد، شود. از این رو پژوهشحاضر با هدف بررسی غلظت عناصر آهن، روی، مس، منگنز و سرب در بافت عضله گنجشک خانگی و ارزیابی خطر مصرف آن در مناطق شهری و روستایی شهرستان دزفول پرداخته است. برای انجام این پژوهش تعداد 60 قطعه گنجشکخانگی از مناطق شهری و 10 قطعه گنجشک از مناطق روستایی شهر دزفول جمعآوری شد. در نهایت میزان فلزات آهن، روی، مس، منگنز و سرب با استفاده از دستگاه جذب اتمی و بهروش هضم اسیدی تعیین شد. میزانهای جذب روزانه و هفتگی فلزات آهن، مس، روی، منگنز و سرب در اثر مصرف گنجشک خانگی کمتر از میزان استاندارد توصیه شده توسط کمیته مشترک سازمان بهداشتجهانی و فائو بود. میزان THQ (Target Hazard Quotients) تک تک فلزات در این مطالعه کمتر از یک بهدست آمد که نشاندهنده عدم وجود هرگونه خطر غذایی در اثر مصرف گونه مورد بررسی با نرخ کنونی میباشد. در مناطقروستایی میزان THQ فلزات آهن، مس، روی، منگنز و سرب به ترتیب برابر0154/0، 0004/0، 003/0، 0001/000065، 0/0 و در مناطق شهری میزان THQ فلزات آهن، مس، روی، منگنز و سرب به ترتیب برابر 01/0، 00069/0، 004/0، 0003/0، 000046/0 به دست آمد. با توجه به نتایج بدست آمده، به نظر میرسد مصرف گنجشکخانگی در حال حاضر خطرات بهداشتی برای سلامت مصرف کنندگان آن ندارد.

Exposure to heavy metals through the consumption of birds may lead to health hazards for individuals, especially in areas where there are agricultural and industrial activities. Therefore, the present study has conducted to risk assessment of iron, zinc, copper, manganese and lead in the muscle tissue of domestic sparrow (passer domesticus) in urban and rural areas of Dezful. The present study was a research study. For this research, 60 house sparrows from urban areas and 10 sparrows from rural areas were collected from Dezful city. Finally, the concentrations of iron, zinc, copper, manganese and lead metals were determined by atomic absorption spectroscopy and acid digestion. Daily and weekly intake of iron, copper, zinc, manganese and lead via consumption of House spparow was less than the standard recommended by the Joint Committee of the World Health Organization and the FAO. The THQ of each metal in this study was less than one, which indicates the absence of any food hazard due to the consumption of the studied species at the current rate. In the rural areas, the THQ values for Fe, Cu, Zn, Mn, and Pb were 0.0154, 0.0004, 0.003, 0.0001, and 0.000065, respectively, and in the urban areas, THQ valus were 0.01, 0.00069, 0.004, 0.0003, and 0.000046, According to the results, it seems that the consumption of house sparrows in the present time does not pose health risks to the health of its consumers.
