چکیده مقاله :

چکیده زمینه و هدف: با توجه به اهمیت موضوع این پژوهش با هدف بررسی عناصر روی، سرب و کادمیوم در محصول برنج عرضه شده در بازار مصرف شهر همدان در سال 1394 انجام یافت. روش بررسی: بدین منظور از 10 نوع محصول برنج موجود در بازار سطح شهر همدان نمونه برداری مطابق روش استاندارد انجام شد. پس از انجام مراحل آماده سازی نمونه‌ها به روش هضم اسیدی، غلظت عناصر در آن ها توسط دستگاه نشر اتمی قرائت شد. پردازش آماری داده ها نیز توسط نرم افزار SPSS انجام یافت. یافته ها: نتایج بیان گر آن بود که کمینه و بیشینه میانگین غلظت عناصر در نمونه های برنج بر حسب میلی گرم در کیلوگرم برای روی با 0002/0±0862/0 و 00781/0±02/1 به ترتیب مربوط به برنج B و C، برای سرب با 00529/0±226/0 و 00529/0±894/4 به ترتیب مربوط به برنج A و H و برای کادمیوم با 001/0± 006/0 و 00436/0± 043/0 به ترتیب مربوط به برنج H و A می باشد. همچنین نتایج بیان گر اختلاف معنی دار آماری میانگین غلظت تجمع یافته فلزات سنگین در نمونه‌های برنج عرضه شده در بازار مصرف شهر همدان با رهنمود WHO می باشد، به طوری که میانگین غلظت عناصر روی و کادمیوم کم تر و میانگین غلظت عنصر سرب بیش تر از حد مجاز می باشد. بحث و نتیجه گیری: در نهایت می توان عنوان کرد گرچه در حال حاضر محصول برنج مصرفی شهر همدان در معرض آلودگی بیش از حد مجاز به فلز سنگین سرب می باشد، تماس بیش از حد با سرب می تواندمنجر به بیماری های غیرمنتظره، مشکلات روانی و رفتاری گردد و تبعات بهداشتی غیر قابل جبرانی را نیز برای مصرف کنندگان به دنبال داشته باشد.

چکیده انگلیسی:

Background and Objective: Considering the significance of the issue, this research was performed to study the elements of Zn, Pb and Cd in the rice products available in the markets of Hamedan in 1394. Method: Accordingly, ten types of that rice were sampled through a standard method. After passing the preparation stages of the samples by acidic digestion method, the concentration of elements was read in Atomic Emission Device. Spss was applied to process the statistical data. Findings: The results indicated that the minimum and maximum average of element concentration in rice samples (according to mlg/kg) were as the following: for Zink with 0.0862±0.0002 and 1.02±0.00781 in B rice and C respectively, for Lead with 0.226±0.00529 and 4.894±0.00529 in A and H rice, and for Cadmium with 0.006±0.001 and 0.043±0.00436 in H and A. The results also showed meaningful, statistical deviation of accumulated concentration average of heavy metals in rice samples available in the markets of Hamedan through WHO. Concentration averages of Zinc and Cadmium are less while concentration average of Lead is more than permissible level. Discussion and Conclusion: Finally, it can be stated that the rice product which is being consumed in Hamedan is exposed to Lead pollution which is more than permissible level and it can cause psychological and behavioral problems and health consequences which cannot be compensated.
