چکیده

در میان آلاینده­های زیست­محیطی، فلزات سنگین از ­جمله خطرناک­ترین آلاینده­ها هستند که دارای اثرات زیست‌محیطی عمده­ای می­باشند. پژوهش حاضر با هدف تعیین فلزات سنگین سرب و قلع در عسل‎های تصفیه­ شده، تصفیه ­نشده و موم‎دار استان زنجان در سال 1394 انجام گرفت. در این پژوهش، تعداد 30 نمونه عسل از استان زنجان به‌صورت تصادفی از عسل­های عرضه شده در بازار جمع­آوری گردید. به‌منظور تشخیص آلودگی به سرب در نمونه‌های عسل‌ از دستگاه جذب اتمی کوره گرافیتی و به­منظور تشخیص آلودگی به قلع‌ از دستگاه جذب اتمی با شعله بر مبنای روش خاکسترسازی استفاده شد. نتایج نشان داد، بیشینه میانگین سرب و قلع به‌ترتیب ppb 116 و ppm 27/221 مربوط به عسل موم­دار بود. مهم‌ترین دلیل آلودگی این عسل­ها به سرب، وجود کارخانه سرب ­و ­روی در استان زنجان و وجود قلع در عسل موم­دار به‌دلیل شکل نگهداری آن که در قوطی­های حلبی (قلع اندود) می­باشد. هم‌چنین مقایسه میانگین میزان فلزات سنگین عسل با استانداردهای سازمان جهانی بهداشت نیز بیانگر آن بود که میزان فلزات سنگین سرب در سه نوع عسل، کمتر از حد استاندارد (ppb 220) و میزان فلز قلع در عسل‎های تصفیه ­نشده و تصفیه ­شده، کمتر از حد استاندارد و در عسل موم‎دار نزدیک به میزان استاندارد (ppm 250) بود. بنابراین موم­دار بودن عسل روی میزان سرب و قلع آن تأثیر داشته است. نتایج به‌دست آمده نشان داد مصرف عسل­های مورد آزمون استان زنجان برای سلامت عمومی خطری ندارد.

چکیده [English]

Among environmental contaminants, heavy metals are the most dangerous pollutants. heavy metals are a major environmental impact. The purpose of present study was to identify Lead and Tin heavy metals in refined, unrefined and beeswax honey in Zanjan Province. In this study, 30 samples of honey were randomly collected from the honey supply at retails of Zanjan province. Determination of Lead and Tin concentrations were applied by graphite furnace atomic absorption spectrometry and flame atomic absorption spectrometry, respectively. According to the results, the highest concentrations of lead and tin were found (116 ppb and 221.27 ppm) in beeswax honey. The reason for the high levels of tin in honey wax is storage of honey in tinned cans. Moreover, the reason for the high contamination of lead in honey samples could be environmental contaminants caused by nearby factories in the region. Comparison of the average heavy metals honey by the standards of the WHO also indicates that lead and tin in all types of tested honey were less than the approved limit (220 ppb). Tin concentration in unrefined and refined honey was less than the standard limit; however, in beeswax honey, it was close to the standard (250 ppm). Besides, beeswax and tin had a remarkable effect on the amount of lead. It was concluded, honey at Zanjan province was wholesome based on Lead and Tin contaminants.
