Presence of heavy metals in agriculture soils above the permissible limit poses threats to public health. In this study, concentrations of seven metals were determined in agricultural soils from Yuhang county, Zhejiang, China. Multivariate statistical approaches were used to study the variation of metals in soils during summer and winter seasons. Contamination of soils was evaluated on the basi...

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. ...

The aim of the research was to determine patterns distribution metals and their main mineral phases in technogenic bottom sediments St. Petersburg watercourses conditions extreme pollution. objects were Yekaterinofka, Okhta, Krasnen'kaya, Smolenka, Karpovka Chernaya Rechka Rivers. Bottom urbanized rivers are characterized by abnormally high concentrations metalloids (TMM). maximum metal content...

Marchica Lagoon, a Ramsar site on the Mediterranean coast of Morocco, is experiencing impacts watershed pollution, which includes pollutants from domestic, agricultural, industrial, and mining sectors. Restoration actions were undertaken around this lagoon during last decade in order to protect its ecological value develop tourist activity. To conserve biodiversity lagoon, it important assess e...

Background: Land and water pollution by heavy metals is a universal issue. Although the pollution affects all countries, but its range and severity vary hugely. The pollution of the marine environment by heavy metals is a worldwide problem. Marine sediments can be sensitive indicators for monitoring contaminants in aquatic environments. Methods: The concentration of 10 elements (As, Cd, Cr, Cu...

air pollution is today a major problem for modern societies. it has long been recognized as a potentially lethal form of pollution. increasing pollution levels due to rapid urbanization and growth in emission related to vehicular transportation are now caused major concern. the mobilization of heavy metals into the biosphere by human activities has become an important process in the geochemical...

The ecological and children’s Health Risk Assessments (HRA) of Copper (Cu) in aquatic bodies ranging from rivers, mangrove, estuaries, offshore areas were studied using the Cited Cu Data Sediments (CCDITS) 125 randomly selected papers published 1980 to 2022. HRA assessed all CCDITS. Generally, local point sources (8%) lithogenic main controlling factors concentrations. present review revealed t...

Soils are the basic and most important resources of any people. Differences in soil’s physical and chemical properties are related to the spatial distribution of land uses. Most of these human activities generate toxic substances that are transported considerable distances away from source and become accumulated in soils, sediment, water bodies and fisheries. Urban soils are largely affected by...

gabrik in the east of hormozgan province is mangrove habitat and one of the important mangrove protected area. this area is located in oman coasts. this zone because of building jagin dam on gabrick river and existence of sand barrier and exposure of pollution, it is possible to destroy or to be important threats of this planet. base on importance of this sea inhabitation some of sedimentology ...
