In this book chapter, the sources of heavy metals in the environment, pathways, ecological fate and footprints, eco-toxicological effects, regulatory frameworks, treatment technologies, valorization options and recovery in light of the future perspectives are explicitly discussed. The possible resources ...
Heavy metals (HMs) are considered crucial toxicants of the environment as they are very toxic, tenacious, easy to accumulate, and nondegradable in nature. HM pollution include some natural sources such as breakdown of rocks possessing metals, eruption of volcanoes and certain human activities like...
Heavy metals are not readily degraded in the environment, and those that enter a water body can remain there for some time. They are usually found in low concentrations in aquatic systems5, and high concentrations of heavy metals in sediments can indicate anthropogenic rather than natural sources...
Heavy metal sources in the environment can originate from natural and anthropogenic activities. Their main natural enrichment in soils stems from parent-material weathering. However, in coastal areas, precipitation of sea spray may enrich soil with B. In contrast, the main anthropogenic sources of ...
Mining has been carried out upstream of Miyun Reservoir, Beijing, for several decades, and has caused metal emissions to the environment, threatening human health. We conducted a soil survey to assess metal contamination in this area and to determine distribution of heavy metals in the particle ...

An atmospheric chemical transport model was adapted to simulate the concentration and deposition of heavy metals (arsenic, cadmium, chromium, copper, lead, nickel, selenium, vanadium, and zinc) in the United Kingdom. The model showed that wet deposition was the most important process for the tran...

Background: Cadmium is a heavy metal found naturally in the environment that has been associated with negative health outcomes. The present study examines levels of blood cadmium (BCd), urinary cadmium (UCd), and the main sources of cadmium exposure among Canadians aged 20 to 79. Data and met...
