چکیده

وجود فلزات سنگین در آب، خاک و محصولات کشاورزی تهدید قابل توجهی برای سلامت انسان به شمار می‌آید. هدف از این مطالعه، ارزیابی فلزات سنگینی همچون جیوه (Hg)، سرب (Pb)، آرسنیک (As)، کادمیم (Cd)، روی (Zn) و کبالت (Co) در برخی سبزیجات مانند خیار، گوجه‌فرنگی و بادمجان و همچنین در منابع خاک و آب گلخانه‌ها واقع در فاصله نزدیک (۱–۱۰ کیلومتر) از مناطق صنعتی بزرگ و مقایسه آن با یک گلخانه واقع در حومه استان اصفهان بود. اندازه‌گیری فلزات سنگین با استفاده از روش ICP-OES و با تکرار انجام شد. غلظت فلزات سنگین در خاک بر اساس منطقه متفاوت بود و به‌طور کلی الگوی نزولی Co > Pb > As > Hg > Zn > Cd را نشان داد. فاکتور انتقال فلزات سنگین نیز به‌ترتیب Cd > Hg > Zn > Pb > Co > As  بود. نتایج نشان داد که مناطق صنعتی بزرگ استان اصفهان وضعیت مخاطره‌آمیزی دارند و قابل توجه است که سطح فلزات سنگین در منطقه حومه اصفهان نیز از شاخص ریسک سلامت (HRI) فراتر رفته است. بر اساس یافته‌ها، پیشنهاد می‌شود که تولیدکنندگان نظارت منظم بر کیفیت آب آبیاری و خاک را انجام دهند، از روش‌های گیاه پالایی و بهبود دهنده‌های آلی خاک برای کاهش جذب فلزات سنگین استفاده کنند و گونه‌های گیاهی کم‌جذب را انتخاب نمایند تا خطرات سلامت کاهش یابد و تولید پایدار در گلخانه‌های نزدیک مناطق صنعتی تضمین شود.

چکیده English

The presence of heavy metals in water, soil, and agricultural products is considered a significant threat to human health. This study aimed to evaluate different heavy metals such as Mercury (Hg), Lead (Pb), Arsenic (As), Cadmium (Cd), Zinc (Zn) and Cobalt (Co), in some vegetable varieties like cucumber, tomato and eggplant and also in the soil and water resources, in greenhouses around the mega industrial zones vicinity (1-10 Km) and comparing it with a greenhouse located in suburb of Isfahan, Iran. Measurement of heavy metals was carried out using ICP-OES in replicate. Concentrations of heavy metals in soil varied by region and generally following the descending pattern: Co > Pb > As > Hg > Zn > Cd. Heavy metals transfer factor were in the order of Cd > Hg > Zn > Pb > Co > As. According to the results, the mega industrial zones of Isfahan province showed a hazardous situation, and notably, heavy metal levels in the suburban region of Isfahan exceeded the health risk index (HRI). Based on the findings, it is recommended that producers adopt regular monitoring of irrigation and soil quality, apply phytoremediation and organic soil amendments to reduce heavy metal uptake, and select low-accumulating crop varieties in order to minimize health risks and ensure sustainable greenhouse production near industrial zones.
