BACKGROUND Heavy metal pollution in the sediment of the Yellow River draws wide attention in the recent years. The Yellow River Wetland Nature Reserve of Zhengzhou is one of the major wetlands of the river and located at the beginning of the lower reach. In this article, we aimed to investigate the degree and the sources of the metal pollution in the reserve. METHODS Metals as Cu, Pb, Cr, Cd ...

Background: The release of metals from industrial factories is one of the most important sources of environmental pollution. The present study aimed to determine the concentration of heavy metals like cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni), and lead (Pb) in dust around the cement factory. Methods: A total of 22 dust samples were collected from areas around the cement factory...

Bacteriophages active against specific Bacteroides host strains were shown to be suitable for detection of human faecal pollution. However, the practical application of this finding is limited because some specific host strains were restricted to certain geographic regions. In this study, novel Bacteroides host strains were isolated that discriminate human and animal faecal pollution in Switzer...

The production and use of chemicals is an important source of economic welfare in Ghana. However, many chemicals also enter the environment and chemical pollution remains a major environmental issue in Ghana. In Ghana, mining and agriculture remain the major contributors to chemical pollution. For mining; mercury, cyanide and arsenic are normally the reported cases of contamination. Studies hav...

Through the years, mining and beneficiation processes produces large amounts of As-rich mine wastes laid up in huge tailings and open-air impoundments (Barroca Grande and Rio tailings) that are the main source of pollution in the surrounding area once they are exposed to the weathering conditions leading to the formation of AMD and consequently to the contamination of the surrounding environmen...

an increase in heavy metal pollution in the soils of arak due to industrialization and urbanization has become an environmental problem. the region hosts several industrial facilities which are the main source for hazardous wastes which include electric, metal, automotive supply industry, food, machinery, and chemicals. soil samples were collected from these industrial areas in the central and ...

As a result of the continuous urbanization and industrialization in China over the last few decades, heavy metals have been continuously emitted into urban environments and now pose serious threats to human health. In the present study, an extensive urban near-surface dust survey was conducted in Changchun, China, to evaluate the current status of heavy metal contamination in urban dust and to ...
