Arsenic (As) is one of the most widespread, toxic elements in the environment and human activities have resulted in a large number of contaminated areas. However abundant, the potential of As toxicity from exposure to contaminated soils is ...
Point of zero charge: Role in pyromorphite formation and bioaccessibility of lead and arsenic in phosphate amended soils [0.03%]
零电荷点在磷灰石改良土壤中红磷钙石形成及铅砷生物可利用性中的作用研究
