Investigation on Wild Plants and Lead Cadmium Carrying Volume around A Lead-Zinc Smelting Plant
摘要
Abstract
The investigation on two-kilometer region around a lead-zinc smelting plant was conducted , 34species of wild plants in18 families were collected, and the contents of lead and cadmium in the soil, as well as the lead and cadmium carrying vol-ume of aboveground part of these plants were analyzed.The results showed that Pennisetum purpureum Schumach, Gaura parviflora, Leonurus sibiricus,R oegneria kamoji, Humulus japonicus and Periploca sepium Bunge absorbed less lead and cadmium, and they had relatively weak enrichment capacity.The cadmium-enriching coefficients of Lithospermum erythrorhizon, Ixeridiums onchifolium ( Maxim.) Shih, Taraxacum mongolicum, Chelidonium majus, Polygonum hdy ropiper, Erigeron annuus, Isatis tinctoria and De-scu rainia sophia were all higher than 1.The cadmium content in the shoots of Rumex acetosa and Daturas tramonium was all the highest, reaching 35.63and 26.17 mg/kg, respectively.These 2 plants also carried the most lead and cadmium, their lead-carrying volume was 20.27 and 37.40 mg respectively, and cadmium-carrying volume was 21.2 and 7.16 mg respectively.So, Pennisetum up rpureum, Gaurap arviflora, Leonurus sibiricus, Roegneria kam oji, Humulus japonicus and Periploca sepium can be used as alterna-tive materials for phytostabilization technology, and they have huge potentials in the phytoremediation of polluted soil.Because Rumxe acte osa and Datura stramonium have strong tolerance and transport capacity to lead and cadmium, these 2 plants possess a certain applied value in the remediation of complicatedly-polluted soil.关键词
