چکیده

در پژوهش حاضر با اندازه‌گیری غلظت جیوه کل با روش اسپکتروفتومتر جذب اتمی در نمونه‌های عضله ماهی شانک زرد باله (Acanthopagrus latus) رودخانه بهمن‌شیر خطر ناشی از مصرف این ماهی برای انسان ارزیابی شد. بدین منظور 30 عدد ماهی از بندر ‌چوئبده به‌صورت تصادفی تهیه شد. میانگین میزان جیوه در عضله ماهی شانک در منطقه مورد مطالعه 08/0±24/0 میلی‌گرم در کیلوگرم وزن تر بود. نتایج نشان می‌دهد که میانگین میزان جیوه در عضله ماهی شانک از حد آستانه استانداردهای جهانی پایین‌تر است. با توجه به میزان مصرف سرانه ماهی در ایران، میزان جیوه‌ای که از طریق مصرف ماهی شانک زرد باله جذب بدن انسان می‌شود، حدود 000085/0 میلی‌گرم در کیلوگرم در روز و 000595/0 میلی‌گرم در کیلوگرم در هفته برای یک فرد بالغ با وزن 70 کیلوگرم است. همچنین میزان شاخص خطر ماهی شانک زرد باله 85/0 می‌باشد که کمتر از 1 است. حداکثر مصرف روزانه ماهی شانک زرد باله با میانگین غلظت 24/0 میلی‌گرم جیوه در کیلوگرم وزن تر برای مصرف‌کننده با میانگین وزن 70 کیلوگرم، 29 گرم در روز و 203 گرم در هفته می‌باشد

چکیده [English]

This study aimed to investigate the concentration of mercury in Acanthopagrus latus of Bahmanshir River using atomic absorption spectrophotometer and also to estimate the consequent health hazard. For this purpose, 30 samples of fish were prepared from Choebdeh seaport. The average concentration of mercury of Acanthopagrus latus was 0.24±0.08 mg/Kg of fresh wet weight of muscle. The results showed that average concentration of mercury in muscle of Acanthopagrus latus was less than the international organizations standards. According to Statistical Yearbook of Iran Fisheries Organization, the calculations indicated that daily and weekly mercury uptake for the adult Iranian consumers (70 Kg), was 0.000085 mg/Kg/day and 0.000595 mg/Kg/weekly. In addition, it was revealed that HQ index for Acanthopagrus latus was 0.85 which was estimated below 1. Accordingly, maximum daily intake of fish contaminated with 0.24 mg mercury/Kg wet weight for a 70 Kg person was estimated at 29 g/day and 203 g/week
