- 摘要:
- 以渭南市区近郊渭河滩地重金属污染的土壤为试材，加入外源Pb、Hg作为模拟污染土壤，通过芹菜盆栽试验，研究了消石灰、腐殖酸、Na2S等化学物质对芹菜吸收土壤重金属的抑制效应及对土壤重金属存在形态的影响。结果表明：适当剂量的化学添加物能有效抑制芹菜对土壤中Pb、Hg的吸收，是缓解或治理重属污染土壤的可行之策。
- Abstract:
- Taking soil heavy metal pollution of Weihe river beach in Suburban Weinan as test materials，adding Pb and Hg as the heavy metals prior controlled，a celery pot experiment was conducted to explore the inhibition effect of slaked lime，humic acid，and Na2S on celery’s ability to absorb heavy metal and the effect on the existing forms of heavy metal in soil.The results showed that an appropriate dose of chemical additives could effectively inhibit vegetable’s absorption on Pb and Hg in soil，which suggested a feasible way to ease or control soil heavy metal pollution.
