Although environmental problems caused by metal mining have become increasingly prominent, the pollution by associated heavy metals is easily neglected. In general, molybdenum mines are lowgrade and hence the high level of associated heavy metals easily causes pollution in the surrounding areas. Here we investigated the total concentrations and forms of Mo and associated Cu, Cd, Pb, and Zn in soils...
This study established a K drought monitoring model to determinate the start, duration, and strength of drought. Based on 586 meteorological stations’ conventional observation data in China from 1961 to 2015, we calculated the elements and parameters needed to structure the model. Because soil has a memory of its antecedent moisture change, the drought intensity of a day is determined by the moisture...
With the liquid crystal displays (LCDs) being widely used in televisions, notebooks, and mobile phones, etc., large quantities of LCDs are entering into their end-of-life stage for treatment. If not treated properly, a loss of resources and undesirable impacts on the environment and human health can occur. In order to treat the waste LCDs in an efficient and environmentally friendly way, a combined...
