Patterns and predictors of personal exposure to indoor air pollution from biomass combustion among women and children in rural China
Indoor air pollution (IAP) from domestic biomass combustion is an important health risk factor, yet direct measurements of personal IAP exposure are scarce. We measured 24‐h integrated gravimetric exposure to particles

We measured 24‐h integrated gravimetric exposure to particles <2.5 μm in aerodynamic diameter (particulate matter, PM2.5) in 280 adult women and 240 children in rural Yunnan, China. We also measured indoor PM2.5 concentrations in a random sample of 44 kitchens. The geometric mean winter PM2.5 exposure among adult women was twice that of summer exposure [117 μg/m3 (95% CI: 107, 128) vs. 55 μg/m3 (95% CI: 49, 62)]. Children’s geometric mean exposure in summer was 53 μg/m3 (95% CI: 46, 61). Indoor PM2.5 concentrations were moderately correlated with women’s personal exposure (r = 0.58), but not for children. Ventilation during cooking, cookstove maintenance, and kitchen structure were significant predictors of personal PM2.5 exposure among women primarily cooking with biomass. These findings can be used to develop exposure assessment models for future epidemiologic research and inform interventions and policies aimed at reducing IAP exposure.
Practical Implications
Our results suggest that reducing overall PM pollution exposure in this population may be best achieved by reducing winter exposure. Behavioral interventions such as increasing ventilation during cooking or encouraging stove cleaning and maintenance may help achieve these reductions.</description><identifier>ISSN: 0905-6947</identifier><identifier>EISSN: 1600-0668</identifier><identifier>DOI: 10.1111/j.1600-0668.2011.00730.x</identifier><identifier>PMID: 21692855</identifier><language>eng</language><publisher>Oxford, UK: Blackwell Publishing Ltd</publisher><subject>Adult ; Aged ; Aged, 80 and over ; Air Pollution, Indoor - analysis ; Air Pollution, Indoor - legislation & jurisprudence ; Air Pollution, Indoor - prevention & control ; Biomass ; Child ; Child, Preschool ; China ; Cities ; Cooking - instrumentation ; Cooking - methods ; Environmental Monitoring ; Female ; Household air pollution ; Household energy ; Housing ; Humans ; Indoor air pollution ; Middle Aged ; Models, Biological ; Particulate matter ; Particulate Matter - analysis ; Personal exposure assessment ; Risk Assessment - methods ; Risk Assessment - trends ; Rural Health ; Rural Population ; Seasons ; Solid fuels ; Ventilation - instrumentation ; Ventilation - methods</subject><ispartof>Indoor air, 2011-12, Vol.21 (6), p.479-488</ispartof><rights>2011 John Wiley & Sons A/S</rights><rights>2011 John Wiley & Sons A/S.</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c4340-88db92b66e2622aa0c1b5b217476f64c7e81c280e7a4b080b93fbdd0ed78ed103</citedby></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fj.1600-0668.2011.00730.x$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fj.1600-0668.2011.00730.x$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,780,784,1417,27924,27925,45574,45575</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/21692855$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Baumgartner, J.</creatorcontrib><creatorcontrib>Schauer, J.
