چکیده

باتوجه به اینکه وجود منابع آلودگی گوناگون، آثار نامطلوبی بر سلامت بوم‌سامانۀ یک منطقه دارد، برآورد میزان آلودگی در منطقه بسیار مهم است. در این مطالعه، غلظت فلزات نیکل، کادمیوم و سرب در بافت نرم دوکفه‌ای Saccostreacucullata در 4 ردۀ سنی و 3 ردۀ طولی در سواحل بندر لافت و به روش ICP-OES بررسی شد.
نتایج نشان داد که میانگین غلظت فلزات نیکل، کادمیوم و سرب در 4 ردۀ سنی به‌ترتیب نیکل (55/78، 77/36، 65/34 و 61/25)، کادمیوم (73/5، 55/4، 70/5 و 03/5)، سرب (74/21، 53/9، 26/8 و 10/8) میکروگرم بر گرم وزن خشک و میانگین غلظت فلزات نیکل، کادمیوم و سرب در 3 ردۀ  طولی به‌ترتیب نیکل (68/74، 61/35 و 67/30)، کادمیوم (65/5، 36/5 و 76/4)، سرب (65/18، 52/9 و 19/9) است که میزان فلزات سرب و کادمیوم در 4 ردۀ سنی و 3 ردۀ طولی براساس استاندارد EPA و FDA بیشتر از حد مجاز بود، اما میزان نیکل در 4 ردۀ سنی و 3 ردۀ طولی کمتر از حد استاندارد بود. ازآنجا‌که این صدف خوراکی است، مصرف آن در هر اندازه ممکن است خطرهای بسیاری برای انسان و سایر موجودات مصرف‌کننده داشته باشد.

چکیده [English]

According to various pollution sources, have adverse effects on the health of ecosystems in a region, It is important to estimate the amount of contamination in the area. In this study, Concentrations of Ni, Cd and Pb in the soft tissues of the bivalve Saccostrea cucullata were examined at 4 ages categories and 3 longth categories in beaches Loft Port by ICP-OES.
The results showed that the mean concentrations of Ni, Cd and Pb were in the 4 age categories Respectively: Nickel (78.55, 36.77, 34.65 and 25.61), cadmium (5.73, 4.55, 5.70 and 5.03), lead (21.74, 9.53, 8.26 and 8.10) micrograms per gram dry weight and The results showed that the mean concentrations of Ni, Cd and Pb were in the 3 longth group Respectively: Nickel (74.68, 35.61, 30.67), cadmium (5.65, 5.36, 4.76), lead (18.65, 9.52, 9.19) micrograms per gram dry weight that Lead and cadmium levels in 3 length categories and 4 age categorieswere higher than the standard limit EPA and FDA but The nickel content in 3 length categories and 4 age categories are less than standard. Since Saccostrea cucllata is oyster, Eating it in any size can be dangerous to humans and other creatures of the consumer
