Health Effects Associated with Inhalation of Airborne Arsenic Arising from Mining Operations

摘要: Arsenic in dust and aerosol generated by mining, mineral processing metallurgical extraction industries, is a serious threat to human populations throughout the world. Major sources of contamination include smelting operations, coal combustion, hard rock as well their associated waste products, including fly ash, mine wastes tailings. The number uncontained arsenic-rich sites world growing concern, people at risk exposure. Inhalation exposures arsenic-bearing dusts aerosol, both occupational environmental settings, have been definitively linked increased systemic uptake, carcinogenic non-carcinogenic health outcomes. It therefore becoming increasingly important identify sensitive sub-populations exposure, better understand modes action for pulmonary arsenic toxicity carcinogenesis. In this paper we explore contribution smelting, mining products atmospheric arsenic. We also report on current understanding effects inhaled arsenic, citing results from various toxicological, biomedical epidemiological studies. This review particularly aimed
