“…Once again, we found that the concentrations of all metals were higher among households using coal for heating than among those using central heating (Supplementary Table 1). Susaya et al (2010) investigated the elemental concentrations of particles emitted during charcoal combustion and found that Cd, Pb, and Zn were most prevalent. However, the concentrations of Co, Pb, and Zn were higher during the non-heating season compared to the heating season in our study, suggesting that these metals may come from sources other than heating.…”

The study aimed to investigate the metal compositions in indoor PM2.5 and the potential health risks they pose to residents of an urban area in China. A total of 41 and 54 households were surveyed in February and September 2013, respectively. The results showed that the indoor concentrations of metals varied depending on the types of cooking fuels used. All measured concentrations of metals were highest among households using coal for cooking. In the majority of households, non-carcinogenic risks were posed by the use of coal. The carcinogenic risks posed by chromium (VI) and arsenic were generally higher among households using coal for cooking than among those using gas or electricity. The multivariate linear regression model suggested a potential adverse effect from arsenic and cadmium on birth weight and gestational weeks. This study also found that cooking fuel was the most significant factor that contributed to the differences in concentrations of metals in indoor PM2.5 and highlighted the importance of using clean energy for cooking and heating.

“…Hg, detected only in the snack-street boiling samples, had an average concentration of 17.9 ng m −3 , which exceeded the WHO guideline (5-10 ng m −3 ) as well. Exposure to these trace metals is a health concern (Pandey et al, 2009;Susaya et al, 2010;Sharp and Turner, 2013). More specifically, they can cause lung and heart diseases and DNA damage.…”

“…Oil compositions can affect the cooking temperature at which they are decomposed and released as smoke fumes (Torkmahalleh et al, 2012). Barbeque charcoal combustion was reported to emit the highest amounts of trace metals in comparison with the other examined sources (Pandey et al, 2009;See and Balasubramanian, 2008;Susaya et al, 2010;Taner et al, 2013). Even though the advanced technologies for household activities and the use of cleaner fuels (e.g., electricity and natural gas) could reduce indoor PM 2.5 level (Oanh et al, 1999;Pekey et al, 2010;See and Atmospheric Research 166 (2015) [83][84][85][86][87][88][89][90][91] Balasubramanian, 2008), cooking is always one of the major sources for indoor PM 2.5 .…”

“…Due to their toxic characters, trace metals are an important component of PM (Senlin et al 2008). Some airborne trace metals may derive from natural crustal source, but the majority results from anthropogenic activities (Okuda et al 2008) with main sources including (Fang et al 2010;Susaya et al 2010) vehicle emissions (primary source for chromium, lead cadmium, and barium), industrial and construction processes (responsible for manganese, aluminum, and silicon), oil (responsible for nickel) and coal combustions (chromium), and metal industry (metal specific). In indoor environments, the abundance of the trace elements results from infiltration of outdoor emissions (Habil et al 2013;Hassan 2012) and from various indoor sources which include different wall paints and indoor equipment and utensils (Chattopadhyay et al 2003;Kebede et al 2013;Paoletti et al 2006;Taner et al 2013).…”

Hospitals are considered as a special and important type of indoor public place where air quality has significant impacts on potential health outcomes. Information on indoor air quality of these environments, concerning exposures to partic-ulate matter (PM) and related toxicity, is limited though. This work aims to evaluate risks associated with inhalation exposure to ten toxic metals and chlorine (As, Ni, Cr, Cd, Pb, Mn, Se, Ba, Al, Si, and Cl) in coarse (PM2.5-10) and fine (PM2.5) particles in a Portuguese hospital in comparison with studies representative of other countries. Samples were collected during 1 month in one urban hospital; elemental PM characterization was determined by proton-induced X-ray emission. Noncarcinogenic and carcinogenic risks were assessed according to the methodology provided by the United States Environmental Protection Agency (USEPA; Region III Risk-Based Concentration Table) for three different age categories of hospital personnel (adults, >20, and <65 years) and patients (considering nine different age groups, i.e., children of 1-3 years to seniors of >65 years). The estimated noncarcinogenic risks due to occupational inhalation exposure to PM2.5-bound metals ranged from 5.88×10−6 for Se (adults, 55-64 years) to 9.35×10 −1 for As (adults, 20-24 years) with total noncarcinogenic risks (sum of all metals) above the safe level for all three age categories. As and Cl (the latter due to its high abundances) were the most important contributors (approximately 90 %) to noncarcinogenic risks. For PM2.5-10, noncarcinogenic risks of all metals were acceptable to all age groups. Concerning carcinogenic risks, for Ni and Pb, they were negligible (<1×10 −6 ) in both PM fractions for all age groups of hospital personnel; potential risks were observed for As and Cr with values in PM2.5 exceeding (up to 62 and 5 times, respectively) USEPA guideline across all age groups; for PM2.5-10, increased excess risks of As and Cr were observed particularly for long-term exposures (adults, 55-64 years). Total carcinogenic risks highly (up to 67 times) exceeded the recommended level for all age groups, thus clearly showing that occupational exposure to metals in fine particles pose significant risks. If the extensive working hours of hospital medical staff were considered, the respective noncarcinogenic and carcinogenic risks were increased, the latter for PM2.5 exceeding the USEPA cumulative guideline of 10 . For adult patients, the estimated noncarcinogenic and carcinogenic risks were approximately three times higher than for personnel, with particular concerns observed for children and adolescents.
