Abstract Background and purpose:The rapid urbanization and industrialization in many parts of the world have led to the accumulation of heavy metals in the terrestrial environment and pose a serious threat to human health. In this study, a broad assessment was conducted to estimate the levels of heavy metals in groundwater in Sistan and Baluchestan via geographic information system (GIS), Iran,...

The study evaluates associated health risks of heavy metals in the soil to inhabitants of two mining areas of Nigeria. For so doing, it collects and analyses nine homogenous soil samples for their lead, copper, cadmium, zinc, and chromium levels, using AAS. The samples are then used to calculate health risks to adults and children. For adult population in Agbaja community, the calculated hazard...

Background: Reprocessing of sewage sludge to agricultural land is preferred to disposal through landfill or incineration due to its potentially beneficial effects on soil fertility from organic matter and plant nutrients, such as N and P, present in the sludge. Therefore, this study was conducted to investigate the impact of sewage sludge and chemical fertilizers on Pb and Cd accumulation in ...

investigations of lake umbozero, the second largest and the deepest lake of the murmansk region, were carried out to detect and define biogeochemical patterns of distribution of the chalcophile elements (hg, cd, pb, as) in water, sediments and organs and tissues of whitefishes. lake umbozero is affected by emissions and effluents from mining and metallurgical enterprises of the murmansk region,...

background: neptunia oleracea or ‘water mimosa’ has a phytoremediation ability which is rarely being assessed. this plant also can be eaten as raw or cooked and but brought such concern on its safety for human consumption. the objective of this study was to assess the phytoremediation ability of water mimosa and its safety for human consumption. methods: water mimosa was treated with pb, cu and...

introduction   heavy metal contamination has disastrous effects on plant productivity and threatens human and animal health. among metals, cadmium (cd) is commonly released into the environment from industrial processes. cd is known to cause cellular damage in plants by producing oxidative stress via the over-production of reactive oxygen species (ros). to combat oxidative damage, plants have d...
