Health benefits from reducing indoor air pollution from household solid fuel use in China--three abatement scenarios.

摘要: Abstract According to the World Health Organization (WHO), indoor air pollution (IAP) from use of solid fuels in households developing world is responsible for more than 1.6 million premature deaths each year, whereof 0.42 occur China alone. We argue that methodology applied by WHO – so-called fuel-based approach underestimates health effects, and suggest an alternative method. Combining exposure–response functions current mortality morbidity rates, we estimate burden disease IAP impacts three abatement scenarios. Using linear functions, find 3.5 [0.8–14.7 95% CI] people die prematurely due year. The central constitutes 47% all China. modest changes cooking rural might have a large impact, reducing annual 0.63 [0.1–3. 2 million. If quality (IAQ) standard set Chinese government (150 μg PM 10 /m 3 ) was met households, 0.9 [0.2–4.8] would be avoided urban areas 2.8 [0.7–12.4] areas. However, this require improvements outdoor addition complete fuel switch clean households. could prevent 0.7 deaths. exposure assessment here probably realistic approach; however, relationships most likely tends overestimate effects. discrepancies between our results estimates also explained “all-cause mortality” which includes important causes death like cardiovascular diseases, conditions known closely associated with particulate pollution, whereas limited respiratory diseases.
