The geochemical characteristics of the hot spring waters in the Rehai and Ruidian geothermal fields, Tengchong County, Yunnan Province, China, are described and their possible environmental impact assessed. The results show that the alkaline spring waters contain high levels of K, Na, F, Cl, SiO2, whereas the only acidic spring water in Rehai geothermal(More)
Total heavy metal (Cd, Cr, Cu, Pb and Zn) concentrations were evaluated in smelting waste, soil, crop and moss samples collected from the Hezhang artisanal zinc smelting areas, Guizhou, China. Soil samples from the cornfield near the smelting sites contained extremely high Cd (5.8-74 mg kg(-1)), Pb (60-14,000 mg kg(-1)) and Zn (260-16,000 mg kg(-1))(More)
BACKGROUND Diabetes mellitus can cause a wide variety of vascular complications and it is one of the major risk factors for cardiovascular diseases (CVD). High glucose can induce vascular endothelial cell apoptosis. In this study, we investigated the effect of radix hedysari polysaccharide (HPS) on the depression of apoptosis of human umbilical vein(More)
Lead, Zn, and Cd in vegetables/crops were investigated in a zinc smelting region in China, and their daily dietary intake by local residents was estimated. It is observed that Pb, Zn, and Cd were in 34.7-91.1, 242-575, and 0.199-2.23 μg g(-1) dry weight in vegetables/crops with their greatest concentrations in leafy vegetable. The daily dietary intake of(More)
Over the past few decades, zinc smelting activities in Guizhou, China have produced numerous slag dumps, which are often dispersed on roadsides and hill slopes throughout the region. During periods of acid rain, these exposed slags release heavy metals into surface water bodies. A column leaching study was designed to test the potential release of the heavy(More)
