Arsenic speciation in the urine and hair of individuals exposed to airborne arsenic through coal-burning in Guizhou, PR China

Elements in Fine Particulate Matter (PM $$_{2.5}$$ 2.5 ) from Indoor Air During Household Stoves Coal Combustion at Xuanwei, China

“…The above concentration ratios suggest samples from ''Laibin'' could have different emission characteristics of hazardous airborne trace elements (Cr, Pb and Cd in this situation) in fine particulate matter to the atmosphere than the ''non-Laibin'' samples. Airborne contaminants could cause symptoms such as pulmonary dysfunction, cardiovascular dysfunction and cancer (Liu et al 2012;Shraim et al 2003). Household coal combustion has been identified to cause endemic arsenosis in southwest Guizhou at China in previous studies (Wei et al 2012;Zheng et al 1999).…”

Application of Organometallic Speciation in Clinical Studies

“…This has made the Guizhou Province one of the most serious arsenicosis-affected areas in China, where symptoms of arsenicosis, such as changes of skin pigmentation, hyperkeratosis of the hands and feet, skin cancer, and liver damage can easily be identified [77,78]. To investigate the extent of exposure to As through coal-burning, urine and hair samples were collected from voluntary subjects, at least 11 of them showing symptoms of arsenicosis [79]. Total As concentrations in the samples were measured by FI-ICP-MS. Further, As speciation was conducted by HPLC-ICP-MS. A RP C18 column operated at a temperature of 50 C was used for As species separation.…”

Arsenic in Natural Environments

“…Arsenic speciation and mineralogy also varies with different deposits. Pyrite is the major arsenic-bearing mineral in many coals (Welch et al, 2000), 592, including the bituminous deposits of the US Appalachians and Illinois Basin (Huggins and Huffman, 1996;Huggins et al, 1997;Kolker, 2000;Goldhaber, Lee and Hatch, 2003), samples from the Gunnedah Basin, New South Wales, Australia (Ward et al, 1999), many European coals (Yudovich and Ketris, 2005), 152, and high-arsenic Chinese coals (Shraim et al, 2003), 41. Unlike ore deposits, arsenopyrite is uncommon in at least US deposits (Huggins and Huffman, 1996), 47.…”
