City water can be polluted by electronic waste and other sources of heavy metals — but collecting, chemically preserving and transporting samples (样本) to laboratories for testing is challenging for remote communities.To make the process more efficient, Emily Hanhauser, a mechanical engineer at the...
Distribution, Sources, and Water Quality Assessment of Dissolved Heavy Metals in the Jiulongjiang River Water, Southeast China In this study, the concentration of eight dissolved heavy metals (Ti, Cr, Mn, Fe, Ni, Mo, Sb, and Ba) in 42 water samples from the Jiulongjiang River, sout... ...
Dissolved trace elements and heavy metals in the Dan River drainage basin, which is the drinking water source area of South-to-North Water Transfer Project (China), affect large numbers of people and should therefore be carefully monitored. To investigate the distribution, sources, and quality of...
Karst aquifers supply to almost a quarter of the world’s population as an important source of drinking water (Ford and Williams, 2007). Southwest China has been known as one of the most highly karstic areas worldwide (Trofimova, 2018). Depends on the distribution of conduits, development of...
Heavy metal contamination of soil may pose risks and hazards to humans and the ecosystem through: direct ingestion or contact with contaminated soil, the food chain (soil-plant-human or soil-plant-animal-human), drinking of contaminated ground water, reduction in food quality (safety and ...
