The forest-water relationship is a hot and important issue in ecohydrology studies. China has implemented many large-scale reforestation programs in the past decades to address growing soil erosion and desertification, but that also caused serious water yield reductions. In this study, based on the simple water balance equation, we made statistical and graphic analyses on the long-term hydrological...
Groundwater vulnerability assessments, using DRASTIC, are important and useful tools for groundwater pollution prevention and control. The DRASTIC method, however, is not appropriate for accurate specific vulnerability assessments where nitrate concentrations are high. A new method has been developed that retains the basic structure of DRASTIC while adding or subtracting parameters, and modifying...
The measured values of river health indexes that are not necessarily in the same range of a certain health grade level cause the problem of how to classify the actual status of river health. To solve such incompatibility and evaluate the health condition of a river ecosystem objectively we can use the river health integrated index (RHI), which was determined by the fuzzy matter-element extension assessment...
Electroplating sludge and associated waste products comprise complex mixtures of metallic elements and may cause serious environmental pollution if discharged without treatment. An effective light industrial process is modified to selectively extract and recover copper and nickel from electroplating sludge. The procedure was developed on a laboratory scale and validated in a small pilot plant. Extraction...
We studied the feasibility of two advanced oxidation processes (AOPs), including the Fenton and ozonation processes, and a conventional sequence batch reactor (SBR) for treating wastewater from polyurethane manufacturing. The results showed that the SBR achieved a COD removal rate of 93.3% when the influent COD concentration was 1,600 mg·L-1, which was 22.1 and 522.1% higher than the best results...
Cadmium (Cd), a potent immunotoxicant, has been reported to affect immunocytes both in humans and in rodents. However, whether such an effect exists in birds is still unclear. To delineate the cytotoxicity of Cd on the bird immunocytes in vitro, chicken splenic lymphocytes were exposed to Cd. A significant increase in the occurrence of cell damage was observed in chicken splenic lymphocytes following...
