چکیده

چکیده
کاربری­ اراضی تأثیر مهمی در غلظت و توزیع عناصر سنگین در خاک دارد. این مطالعه با هدف تعیین غلظت کل و قابل عصاره‌گیری با DTPA عناصر سرب، روی، مس و نیکل در کاربری­های اراضی مختلف (زراعی، مرتع، شالیزار، باغ) و مناطق جغرافیایی منتخب (دشت زنجان­رود، میانه و طارم) با تأکید بر تغییرات عمقی آنها انجام گرفت. نتایج نشان داد که هر یک از کاربری­های اراضی تأثیر متفاوتی بر غلظت کل و قابل عصاره‌گیری عناصر دارند. همچنین، میزان غلظت عناصر در مناطق جغرافیایی مختلف متفاوت بود. بالاترین غلظت سرب، روی و مس در تمام کاربری­ها مربوط به عمق 20-0 سانتی­متری بود که با افزایش عمق از غلظت آن کاسته شد. در حالی که روند تغییرات عمقی نیکل کل متفاوت­تر از سایر عناصر بود و بالاترین غلظت مربوط به عمق 60-40 سانتی­متر مشاهده شد. غلظت قابل عصاره‌گیری همه عناصر در عمق اول بیشتر بود و در عمق­های پایین­تر از غلظت آنها کاسته شد. با توجه به نتایج حاصل و بررسی منابع مختلف، به نظر می­رسد منابع ورودی عناصر سرب، روی و مس باهم مشترک بوده و بیشتر متأثر از فعالیت­های انسانی می‌باشند در حالی که نیکل تحت تاثیر مواد مادری و شرایط طبیعی زمین می­باشد

چکیده [English]

Heavy metals in soil exhibit distinct characteristics that significantly affect environmental health and safety. This study examined the total concentrations and DTPA-extractable fractions of lead (Pb), zinc (Zn), copper (Cu), and nickel (Ni) across different land uses (agricultural, pasture, rice field, and vineyard), geographical locations (Zanjanrud, Mianeh, and Tarom plains), and soil depths (0-20, 20-40, and 40-60 cm). The highest total and extractable concentrations of Pb, Zn, and Cu were consistently observed in the surface layer (0-20 cm). Nickel distribution showed different patterns, with pastures in Zanjanrud and vineyards in Mianeh had the highest total Ni concentrations at 40-60 cm depth, while Tarom pastures had maximum Ni levels at 20-40 cm. DTPA-extractable Ni concentrations were highest in the surface layer across all regions, particularly in Zanjanrud pastures, Mianeh vineyards, and Tarom pastures. Source analysis revealed that Pb, Zn, and Cu concentrations were predominantly influenced by anthropogenic activities, whereas Ni distribution was mainly controlled by natural factors and parent material composition. These findings highlight the importance of considering both land use practices and natural geochemical processes in soil heavy metal management.
