Environmental contamination characteristics of heavy metals from abandoned lead–zinc mine tailings in China

open access: yesFrontiers in Earth Science, 2023
China holds large-scale lead–zinc mineral resources; however, mining activities often cause severe contamination by heavy metals. This study systemically assessed contamination by eight heavy metals (Cu, Zn, Cd, Pb, Cr, Hg, Ni, and As) in mine tailings ...

Waste and Waste Management

open access: yesAnnual Review of Anthropology, 2015
Discard studies have demonstrated that waste is more than just a symptom of an all-too-human demand for meaning or a merely technical problem for sanitary engineers and public health officials. The afterlife of waste materials and processes of waste management reveal the centrality of transient and discarded things for questions of materiality and ...
