To investigate the characteristics and potential sources of heavy metals pollution, surface sediments collected from Bohai Bay, North China, were analyzed for the selected metals (Cd, Cr, Cu, Ni, Pb, and Zn). The Geoaccumulation Index was used to assess the level of heavy metal pollution. Pb isotopic compositions in sediments were also measured to effectively identify the potential Pb sources. ...

heavy metal pollution all around the world has become a major environmental concern and the bioremediation of polluted environments is an increasingly popular strategy due to both its efficiency and safety. in this study, a bacterial strain resistant to heavy metal was isolated from metal contaminated sites. strain mkh2 was removed pb (ii) with 95.06%. this isolate was also resistant to zinc, c...

In recent decades, contaminations with heavy metals ions have adversely affected the environment, food safety, and human health. Heavy metals, leaching to water sources from industrial effluents, can enter into aquatic chains of humans animals a variety anthropogenic sources. metal detection has been an intensive area research today. Both laboratory-based analytical instruments innovative senso...

Trace metal pollution in farmland threatens the health of both crops and humans. Restoring these polluted farmlands safely utilizing them to elevate farmers‘ incomes are extremely needed. Phytoremediation is a promising method for extracting but its popularization limited by low efficiency economic value plants used. Herein, field study was conducted investigate potential using rotation with hy...

this study at first level focused on definitions and descriptions of  some landfills and landfills sites all around the world and  survey on how important they are for regional governments and responsible in duty  as a very important responsibility for locals and their health. at the second level we had a look on heavy metals concentration which are by many definitions as follows: lead, nickel,...

background: groundwater is the most important source of water supply in industries and agricultures; therefore the need to protect this valuable resource against pollution is felt more than ever. in this study, the possible impact of yazd municipal solid waste landfill was investigated on the chemical quality of the area’s groundwater. methods: groundwater samples were collected from three well...
