| حضور فلزات سنگین در آب و خاک به دلیل داشتن اثرات سمی برای موجودات زنده تبدیل به یک معضل جدی برای محیط‌زیست شده است. تثبیت فلزات سنگین در احیاء خاکهای آلوده به فلزات سنگین یکی از روشهای کم‌هزینه و سریع میباشد. به منظور بررسی تأثیر دیاتومیت بر توزیع شکلهای شیمیایی سرب در خاک، آزمایشی به‌صورت فاکتوریل در قالب طرح کامل تصادفی در سه سطح دیاتومیت (0، 2 و 5 درصد وزنی) و چهار زمان خوابانیدن (1، 2، 4 و 8 هفته) در دو خاک آلوده و در سه تکرار انجام شد. توزیع عناصر در زمانهای مذکور با روش عصارهگیری متوالی تعیین و برای ارزیابی وضعیت تحرک پذیری سرب در خاکهای موردمطالعه، از شاخص توزیع کاهش‌یافته (IR) و شاخص تحرک (MF) استفاده شد. نتایج بدست آمده نشان داد، کاربرد دیاتومیت موجب کاهش معنیدار (P ≤ 0.01) سرب در بخشهای تبادلی و کربناتی و افزایش معنیدار آن در بخشهای متصل به اکسیدهای آهن و منگنز، آلی و باقیمانده نسبت به خاک شاهد شده است. با افزایش سطوح دیاتومیت افزودهشده به خاک و زمان انکوباسیون، مقدار IR و pH افزایش، اما مقدار MF و بخش قابل عصاره گیر با DTPA سرب کاهش نشان داد که بیانگر کاهش تحرک سرب با افزایش سطح دیاتومیت و زمان خوابانیدن است. کاهش تحرک سرب در خاک لوم رسی نسبت به خاک لوم شنی احتمالا به دلیل محتوای بیشتر رس و محتوای کمتر کربنات کلسیم معادل بود. به طور کلی میتوان بیان کرد که افزودن دیاتومیت به خاک آلوده به ویژه در سطوح بالاتر (5 درصد)، منجر به کاهش زیست‌فراهمی و تحرک سرب در خاک میشود. | ||

| چکیده [English] | ||
| The presence of heavy metals in water and soil are major concern for the environment due to their toxicity to many life forms. Stabilization of heavy metals in remediation of contaminated soils is one of the cost-effectiveness and rapid implementation method. In order to study the effect of diatomite on chemical forms of Lead in calcareous soils, a factorial experiment was conducted in a completely randomized design (CRD) with three levels of diatomite application in soil (0, 2 and 5 % by weight), four levels of incubation time (1, 2, 4 and 8 weeks) and in twocontaminated soils with three replications. Chemical distribution of Lead in soils were determined using Tessier sequential extraction method during the mentioned incubation times and reduced partition index (IR) and mobility factor (MF) of the metals were calculated as a Lead mobility indices in the soils. The obtained results showed that the application of diatomite significantly (p ≤ 0.01) decreases the lead in the exchangeable and carbonate fractions and increases it in the iron and manganese oxide, organic and residual bond fractions significantly in comparison to the control treatment. The IR and pH values increased but MF and DTPA-extractable Lead values decreased with increasing diatomite level and incubation time which demonstrates a decrease in the mobility of lead in the soils. Lead mobility reduction in the clay loam soil compared to the one in the sandy loam soil was probably due to higher content of clay and lower content of Calcium Carbonate Equilibrium. Generally, itcan be concluded that the addition of diatomite into the soil especially with high levels (5%) reduces the bioavailability and mobility of the Lead in the soil. | ||
