Urban spotted hyenas ( Crocuta crocuta ) in Ethiopia are a prime example of large carnivores coexisting with little to no conflict people human-dominated landscape, providing valuable waste-removal service. To gain insight how this urban lifestyle persists across generations, we studied hyena group composition at the city waste dump Mekelle, regional capital northern Ethiopia. We found that cub...

Informal electronic waste (e-waste) recycling results in serious environmental pollution of polybrominated diphenyl ethers (PBDEs) and heavy metals. This study explored whether there is an association between PBDEs, heavy metal and key growth- and development-related hormones in children from Guiyu, an e-waste area in southern China. We quantified eight PBDE congeners using gas chromatographic ...

Landfills receiving a mix of waste, including organics, have developed dramatically over the last 3-4 decades; from open dumps to engineered facilities with extensive controls on leachate and gas. The conventional municipal landfill will in most climates produce a highly contaminated leachate and a significant amount of landfill gas. Leachate controls may include bottom liners and leachate coll...

Antidumping reform is critical to a successful completion of the Doha Round of multilateral trade negotiations and US willingness to engage in such reform is key to this effort. This paper assesses prospects for such reform by analyzing US implementation of Uruguay Round antidumping reform commitments. The results strongly suggest that the US has lived up to only the letter but not the spirit o...

The main objective of the study was an assessment of the pollution level of agricultural land located close to dumps of industrial waste remaining after former Zn and Pb ore processing in Poland. The integrated geophysical-geochemical methods were applied for assessment of soil quality with respect to trace element pollution. Additionally, human health risk induced by the contaminated arable so...

Dump engineering is an important part in production processes of open-pit mining. In order to complete the mine production tasks smoothly, it is necessary to make the most of land possessed by the dump in an economical and reasonable way. In the paper, we use the dump of Qidashan iron mine which belongs to Anshan Iron and Steel Group as an engineering background to achieve the aim of improving ...

tailings in the deep ocean and their biological impacts is a signifi cant cause for concern.” The material can smother ecosystems at the disposal site, and if toxic metal ions are released into the water they may end up in the food web. The EU is currently producing new guidelines for best practice in the marine disposal of mining waste. On top of these legally permitted assaults on the oceans,...

Women’s involvement in collective struggles for environmental quality has surged in recent years, as has research focusing on this phenomenon. Consistent with this research, a feminist lens is useful in revealing a model of community struggle that features women’s activities and strategies to expose environmental insult. I use a case study of community protest in Hermosillo, a city in the Mexic...

The need to engineer cover systems for the successful rehabilitation or remediation of a wide variety of solid wastes is increasing. Some common applications include landfills, hazardous waste repositories, or mine tailings dams and waste rock/overburden dumps. The brown coal industry of the Latrobe Valley region of Victoria, Australia, produces significant quantities of coal ash and overburden...
