“…In some areas the coals have undergone a geologic process called epigenetic mineralization resulting in extraordinarily high concentrations of arsenic (100-9,000 ppm) within the coal (6-9)-much higher than the arsenic levels in coal in the United States and other countries (about 10 ppm) (7)(8)(9). Arsenic concentrations in certain coal deposits even reach 35,000 ppm, a truly astounding level (9).…”

“…Occupational exposure to arsenic through inhalation of arsenic dust and environmental exposure through arsenic-contaminated drinking water have been extensively documented and are primary routes of exposure with typical patterns of toxic lesions, including cancer (1)(2)(3)(4)(5). Arsenicals can also be emitted to the air by coal combustion (1)(2)(3), and some coals are unusually high in arsenic because of geologic factors (6)(7)(8)(9). However, little is known about the health effect from domestic use of arsenic-containing coal.…”

Arsenic is an environmental hazard and the reduction of drinking water arsenic levels is under consideration. People are exposed to arsenic not only through drinking water but also through arsenic-contaminated air and food. Here we report the health effects of arsenic exposure from burning high arsenic-containing coal in Guizhou, China. Coal in this region has undergone mineralization and thus produces high concentrations of arsenic. Coal is burned inside the home in open pits for daily cooking and crop drying, producing a high concentration of arsenic in indoor air. Arsenic in the air coats and permeates food being dried producing high concentrations in food; however, arsenic concentrations in the drinking water are in the normal range. The estimated sources of total arsenic exposure in this area are from arsenic-contaminated food (50-80%), air (10-20%), water (1-5%), and direct contact in coal-mining workers (1%). At least 3,000 patients with arsenic poisoning were found in the Southwest Prefecture of Guizhou, and approximately 200,000 people are at risk for such overexposures. Skin lesions are common, including keratosis of the hands and feet, pigmentation on the trunk, skin ulceration, and skin cancers. Toxicities to internal organs, including lung dysfunction, neuropathy, and nephrotoxicity, are clinically evident. The prevalence of hepatomegaly was 20%, and cirrhosis, ascites, and liver cancer are the most serious outcomes of arsenic poisoning. The Chinese government and international organizations are attempting to improve the house conditions and the coal source, and thereby protect human health in this area.

“…The health and environmental threats posed by inorganic toxic elements in coal are the potential release of these elements from coal to the environment during coal combustion and their potential hazard in groundwater if they are leached from coalmining waste, or from fly ash at disposal sites. Such hazards are of great public concern (Diehl et al 2012;Miller 2011;Schweinfurth 2003;Swaine & Goodarzi 1995; US EPA 2000; US Public Law 1990; Vejahati et al 2010;Zheng et al 1999). Nonetheless, the potential hazard of the inorganic toxic elements to the groundwater is beyond the scope of this study.…”

“…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). The combustion process associated with boiling can lead to ultrafine particles to the atmospheres (Varshney et al 2016).…”

The characteristics of elements in fine particulate matter (PM 2:5 ) emitted during indoor coal combustion in Xuanwei were investigated. Lead (Pb) emissions were high among the trace elements at all sampling locations. The average Pb concentrations in ''Laibin'' samples were $ 1.5 time higher than ''non-Laibin'' samples and were statistically significantly difference (paired t test). Concentration ratios normalized to total suspended particles for the elements were also characterized and compared between the two types of locations. Element ratio (Se/S) values were different with another study, suggesting possible different composition characteristics of the samples in Xuanwei compared with other regions in China. These findings provide information about concentrations of elements in different types of coal samples emission during household coal combustion. There is a need to address the health effects of environmentally relevant doses of elements in fine particulate matter, considering life-long exposure of people in indoor dwellings.
