چکیده

فلزات سنگین به‌راحتی می‌توانند باعث آلودگی زیست محیطی آبزیان به‌خصوص میگوها شوند که یکی از ارزشمندترین منابع در زنجیره غذایی انسان‌ها محسوب می‌شوند. هدف از این مطالعه، بررسی غلظت فلزات سنگین (آهن، سرب و کروم) بافت عضله میگوی هندی (Fenneropenaeus indicus) در جاسک و تنگه هرمز و مقایسه آن‌ها با استانداردهای جهانی می‌باشد. تعداد 60 نمونه میگوی هندی از صید روزانه صیادان جاسک و تنگه هرمز در آبان ماه 1394 تهیه شدند. پس از شست و شو، بافت خوراکی میگو جداسازی و در آون در دمای 65 درجه سانتی‌گراد به‌مدت 74 ساعت خشک گردید. و پس از انجام عملیات هضم اسیدی، غلظت فلزات سنگین نمونه‌ها به‌وسیله دستگاه جذب اتمی اندازه‌گیری شد. نتایج نشان داد که تفاوت معنی‌داری بین غلظت فلزات آهن و سرب و کروم بافت عضله میگو در جاسک و تنگه هرمز وجود داشت (05/0>P). بیشترین غلظت کروم و سرب به‌ترتیب 07/0± 82/0 و 08/0±14/0 میلی‌گرم در کیلوگرم وزن خشک در جاسک و بیشترین غلظت آهن (45/0± 29/6 میلی‌گرم در کیلوگرم وزن خشک) در تنگه هرمز مشاهده شد. نتیجه این بررسی نشان داد که غلظت فلزات سنگین آهن، کروم و سرب (به استثنای کروم در جاسک) در عضله میگو از استاندارد‌های گزارش شده توسط سازمان بهداشت جهانی (WHO) کمتر بوده و نگران کننده نمی‌باشد. هر چند میانگین غلظت کروم در عضله میگوی بندر جاسک از حداکثر مجاز برای مصارف انسانی بالاتر بوده و نیاز به بررسی و حساسیت بیشتری دارد.

چکیده [English]

Heavy metals can easily contaminate aquatic animals especially shrimps, which are one of the most valuable resources in the food chain of humans. The aim of this study was to evaluate the concentration of heavy metals (Fe, Cr and Pb) in the muscle tissue of Fenneropenaeus indicus in Jask and Strait of Hormuz and compare them with global standards. Thirty samples of Fenneropenaeus indicus were obtained in October 2015 from daily hunting of fishermen in Jask and Strait of Hormuz. Then the muscle tissues were washed and dried in oven at 65 °C for 74 hours. Following acid digestion, the measurement of heavy metals concentration was performed by Atomic absorption spectrometry. Results showed that there was a significant difference between Cr, Fe and Pb concentrations in shrimp muscle in Jask and Strait of Hormuz (P<0.05). The highest concentration of Cr (0.82± 0.07 mg/kg dry weight) and Pb (0.14± 0.08 mg/kg dry weigh) were observed in Jask and the highest concentration of Fe (6.29± 0.45 mg/kg dry weight) was observed in Strait of Hormuz. The results of this investigation showed that the concentration of heavy metals including Fe, Cr and Pb (except Cr metal in Jask) in the shrimp muscle were less than the amounts reported by WHO and so they were not risky for health. However, the concentration of Cr in shrimp muscle was more than the recommended consumption limit for the humans, and it needs to be controlled cautiously.
