title: Sources, health effects and control strategies of indoor fine particulate matter (PM2.5): A review.
abstract: Indoor air quality is directly influenced by indoor PM2.5. Short-term and long-term exposure of PM2.5in the micro environment would severely detriment the health of both humans and animals. The researches both at home and abroad dating from 2000 were analyzed and summarized mainly in the following 3 sections: source apportionment, health effects and control methods. Health effects were illustrated in both epidemiology and toxicology. The epidemiology was explicated in morbidity and mortality, the toxicology was illuminated in inflammatory reaction, oxidative stress, genotoxicity, mutagenicity and carcinogenicity. Control methods were showed in two aspects (sources and means of transmission), of which each was resolved by corresponding control strategy. Abundant investigations indicated that comprehensive control strategies were needed for sources decrement and health burden mitigation of indoor PM2.5. Based on the increasingly wide research of indoor PM2.5, the concept of indoors was essentially expanded, and on the basis of the summary of all the aspects mentioned above, both the scope and depth of indoor PM2.5research were found insufficiently. Meantime, the potential direction of development in indoor PM2.5research were projected, in hope of contributing to further relevant study of engineers in ambient environment and building environment.
