Seit 2021 müssen Unternehmen, die Tantal, Wolfram, Zinn und Gold in die Europäische Union (EU) importieren und einen bestimmten Schwellenwert überschreiten, Sorgfaltspflichten umsetzen um zu verhindern, durch ihre Beschaffungspraktiken zu Konflikten und Menschenrechtsverletzungen beizutragen....

Integrated recycling of solid wastes containing heavy metals is a critical environmental challenge. In this study, a green solution to reduce heavy metal leaching from solid waste is demonstrated by combining contaminated soil, industrial sludge and lithium slag in pairs to produce lightweight...

Many studies have found that bioretention systems are very effective in reducing heavy metal content. However, their long-term treatment performance, as well as the heavy metal variations in the systems are rarely explored. This paper reports a field study that the accumulation of chromium (Cr),...

Rehabilitation of disused mine sites through stabilisation and botanical restoration is ecologically important, but metal transfer pathways to colonising wildlife are often less understood and have never been studied in marsupials. The rehabilitated Royal George tin mine tailings and...

Heavy metal mitigation is an ongoing environmental problem in aquatic ecosystems. However, a lack of quantitative analysis and accurate evaluation have led to unguided control and water management strategies. Lake Yangzong is the main freshwater resource for nearly one million people in Yunnan...

Two municipal solid waste incineration fly ashes were selected for washing by deionized water and Na 2 CO 3 solution. Results showed that the benefits of washing were two folds: (1) It reduced the contents of Cl - and SO 4 2- while increased the contents of CaO, SiO 2 , Al 2 O 3 etc.; (2) Heavy...

Water pollution is one of the major global threats brought about by industrial, agricultural, and any other antropogenic activity. Heavy metals represent a large group of water pollutants that can accumulate in the human body, causing cancer and mutagenic diseases. Technologies currently used to...

Heterogeneous peroxymonosulfate (PMS) activation by cobalt-based catalysts has drawn much attention due to the high-performance property of cobalt ions (Co(II/III)) to activate PMS. However, the leaching and residue of Co(II/III) in water is still a hurdle to the long-term development of...

Heavy metal pollution and the potential for co-selection of antibiotic resistance in the environment is growing concern. However, clear associations between specific heavy metals and types of antibiotic resistance in river systems have not been developed. Here we investigated relationships...

This paper provides evidence that the rapid increase in the demand for lithium-ion batteries has reduced the education rates of individuals living in cobalt-rich regions of the Democratic Republic of the Congo (DRC). In contrast with other minerals, I find that children in cobalt-mining villages...

Samsung has been implicitly linked to human rights abuses and wider social downgrading propagated within the Democratic Republic of Congo (DRC). Reports by different studies have shown artisanal cobalt mines (ASM) to exploit child labour and subject workers to perilous conditions. The IT...

This paper provides evidence that the adoption of modern lithium-ion batteries led to a decline in child education in the Democratic Republic of the Congo. In contrast with any other mining activities, I find that the rapid increase in the worldwide demand for cobalt led to a reduction in the...

Klappentext: "An unflinching investigation reveals the human rights abuses behind the Congo's cobalt mining operation-and the moral implications that affect us all. Cobalt Red is the searing, first-ever exposé of the immense toll taken on the people and environment of the Democratic Republic of...

Being rich of crucial minerals might be a leading determinant of local economic development. On the other hand, intensive extraction might prove to negatively affect the health and wealth of people living close to mineral deposits and the surrounding environment. I examine the effects that local...

Les Panama Papers de la République Démocratique du Congo: pourquoi ce pays potentiellement riche est-il si pauvre? Dans 'Cobalt blues', le journaliste Erik Bruyland se plonge dans l'histoire postcoloniale de son pays natal, la République Démocratique du Congo. Le passé colonial belge s'est...

Metallurgy is one of the industry producing the most diverse range of wastes in terms of their composition and level of heavy metals contamination. With the development of economy, the amount of produced wastes increases. It involves with the searching for new methods of waste management. The...

Trans-Nzoia county covers an area 2,469.90 Km2 with a total Population of 818,757 (Male 50%, Female 50%) and a poverty index of 5.2% (KNBS, 2011). The main economic activities in Tran-Nzoia county include horticulture, large and small scale maize farming , wheat farming, Tea, Coffee and fish...

This paper considers the health and environmental burdens and impacts of the extraction and refining of selected metals (copper, rare earth elements and cobalt) and how impacts can be reduced through the transition to a circular, low-carbon economy. Performance in the global industry is...

Sediments in estuary areas are recognized as the ultimate reservoirs for numerous contaminants, e.g., toxic metals. Multivariate analyses by chemometric evaluation were performed to classify metal ions (Cu, Zn, As, Cr, Pb, Ni and Cd) in superficial sediments from Lingdingyang Bay and to...

Concentrations of lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), zinc (Zn) and manganese (Mn) were measured in various organs (such as in liver and muscle) from 9 species of freshwater economic fishes which were collected from northeast area of Guangdong Province. The concentration of...

Hazardous heavy metal pollution of soils is one of the most important environmental problems throughout the world. In fact, heavy metals have a significant toxicity for humans, animals, plant and microorganisms. Our results indicate that enzymatic activities are a great utility for understanding...

Contamination by heavy metals is on rise and is threatening our environment and lives. A seemingly insignificant concentration of metals, can in turn be a potential threat to the well being of flora and fauna in the long run. Animals are a good tool to biomonitor the concentration of heavy...

The contents, speciation, source factors and potential ecological risks of the selected metals (Cr, Ni, Cu, Pb, Zn, Cd and As) were analyzed in surface sediments from Daya Bay (DYB). The results show that, with the exception of Pb, metal concentrations have decreased at all sites over the past...

More than 20 soil samples were collected from tea gardens of specialized tea towns in Guangdong, including Fenglang Town and Fengshun Town in Meizhou City, Changshan Town in Lianjiang City, Fenghuang Town in Chaozhou City. Content of 6 types of heavy metal (Cr, Cu, Pb, As, Cd, Hg) in tea garden...

The technology of in situ immobilization with amendments is an important measure that remediates the soil contaminated by heavy metal, and selecting economical and effective modifier is the key. The effects and mechanism of steel slag, the silicon-rich alkaline by-product which can remediate...

The invertebrates constitute important indicators in the appreciation of the soil. A first step in this respect is constituted by the analysis of the heavy metals in the corn fields in the Axente Sever and Copsa Micaƒ Area. Methods of researching: collecting the samples in the soil by using the...
