چکیده مقاله :
زمینه و هدف: با توجه به اهمیت استفاده از سبزیجات سالم، کنترل غلظت عناصر سنگین جهت حفظ سلامتی مصرف کننده حائز اهمیت است. لذا این تحقیق با هدف ارزیابی خطرات فلزات سنگین بر سلامت انسان از طریق مصرف محصولات کشاورزی انجام گرفته است. روش بررسی: نمونه ها شامل بادمجان، گوجه فرنگی، خیار گلخانه ای و توت فرنگی بودند که به صورت تصادفی از گلخانه های جیرفت جمع آوری شدند و غلظت عناصر سرب و کادمیوم در محصول و میوه این گیاهان اندازه گیری شد و مقدار دریافت روزانه هر عنصر (EDI) برای هر محصول با توجه به مقدار مصرف روزانه هر محصول مشخص گردید.یافته ها: میانگین غلظت سرب و کادمیوم در محصولات نمونه برداری شده با یکدیگر متفاوت بود، بیشترین و کمترین مقدار کادمیوم به ترتیب مربوط به بادمجان و خیار گلخانه ای بود. نتایج نشان داد که مقدار سرب و کادمیوم در محصولات بادمجان، گوجه فرنگی و توت فرنگی بیشتر از محدوده استاندارد ارائه شده براساس توصیه موسسه استاندارد و تحقیقات صنعتی ایران و سازمان جهانی بهداشت و خوار و بار و کشاورزی بوده است.بحث و نتیجه گیری: نتایج این تحقیق نشان داد در اغلب محصولات نمونه برداری شده مقدار فلزات سنگین سرب و کادمیوم بیش از حد مجاز است. با این حال مقدار دریافت روزانه هر عنصر (EDI) نشان داد همه محصولات مورد آزمایش، دارای EDI کمتر از میزان دریافت قابل تحمل روزانه موقتی (PTDI) که از طرف موسسه استاندارد ایران گزارش شده است، می باشند. در مجموع، با توجه به نتایج این مطالعه می توان نتیجه گرفت که مصرف این محصولات هیچ تأثیر منفی بر سلامت مصرف کنندگان ندارد.
چکیده انگلیسی:
Background and Objective: Regarding the importance of using the healthy vegetables, it is important to control the concentration of heavy metals in order to provide the health of consumers. Therefore, this study was done with the aim of investigating the evaluation of the risk of heavy metals on human health trough consumption of greenhouse products.Material and Methodology: Samples included eggplants, tomatoes, greenhouse cucumbers and strawberries, were collected randomly from Jiroft greenhouses and the concentration of lead and cadmium in leaves and fruits of these plants were measured. The amount of EDI was defined for each product according to daily consumption.Findings: The average concentration of lead and cadmium in samples were different. The highest and the lowest amount of cadmium respectively belonged to tomatoes and greenhouse cucumbers. The results showed that levels of lead and cadmium in most of the products were more than the standard range recommended by the institute of Standards and Industrial Research of Iran and the FAO-WHO.Discussion and Conclusions: The results showed that the amount of lead and cadmium exceeded the standard index, However the amount of EDI was less than or equal to PTDI reported by Standards Institute's of Iran. Overall, according to the results of this study, it can be concluded that the consumption of these products has not any negative effects on the consumers' health.
