Knowledge from the negative impacts of the counties economic development and urbanization on soil pollution was of great significance in China,and valuable information was urgently needed for soil con
重金属是生态环境中的主要污染物之一,会对海洋生态系统的健康造成不利影响。于2018 年10 月在河北黄骅近岸海域采集32 个站位的表层海水样品,Cu、Zn、Pb、Cd 和Cr 的含量采用电感耦合等离子体质谱法测定;重金属Hg 和As 的含量采用原子荧光法测定。
本研究以改性镁系矿物和海泡石添加下牛粪蚯蚓反应器中所获蚓粪为研究对象,分析蚓粪性状变化规律及其对Pb2+、Cd2+的去除特性差异。
Nitrification and denitrification are two important processes in the nitrogen(N)cycle.
In this study,Kochia scoparia,a C4 perennial native herbage with an excellent tolerance to drought and salinity,was investigated with an aim to assess its phytoremediation potential of Cd in saline so
In recent years,due to improper dismantling of electronic waste(e-waste)in China,high level of lead(Pb)and polychlorinated biphenyls(PCBs)were released into environment,which posed potential health ri
Mercury is a widespread environmental contaminant with high toxicity.1 Therefore,Development of novel methods for mercury ion is urgent.
土壤中过量的铜是常见的无机污染物之一,目前关于土壤铜的田间长期钝化修复实例鲜见报道。田间钝化修复试验可较为真实反映钝化修复效果,因此采用田间试验方法探究不同钝化材料对土壤铜的钝化修复效果具有一定意义。
随着我国工矿业的不断发展,工矿业区周边农田土壤的重金属污染越来越严重,由于重金属污染的隐蔽性,对重金属污染的调查和评估也越来越受到广泛关注。
酸性土壤质量退化,重金属活性高、污染风险大,为改良酸性土壤,控制其重金属污染风险,本研究选择蚯蚓粪、零价铁和磷灰石为原料,设计其不同组配方式共7个处理,包括对照(CK)、蚯蚓粪(VC)、蚯蚓粪+零价铁(1∶1,VCFe)、蚯蚓粪+磷灰石(1∶1,VCP)、蚯蚓粪+零价铁+磷灰石(1∶1∶1,V1F1P1;3∶2∶1,V3F2P1; 3∶1∶2,V3F1P2),通过分析Cd、Pb有效态和钝化效率,评
