Health risks caused by short term exposure to ultrafine particles generated by residential wood combustion: A case study of Temuco, Chile

A work group report on ultrafine particles (American Academy of Allergy, Asthma & Immunology): Why ambient ultrafine and engineered nanoparticles should receive special attention for possible adverse health outcomes in human subjects

“…130 More recently, a case-control study from Chile found that increased outpatient visits due to respiratory illness were significantly correlated with increased levels of UFP generated from residential wood burning. 131 More evidence looking at the association between UFP and allergic diseases came from children's studies. A time-stratified, case-crossover study involving 74 children showed that the largest increase in the relative odds of pediatric asthma visits was associated with the 4-day mean concentration of ambient UFP, but not with accumulation mode PM, black carbon, and sulfur.…”

Sensitivity analysis of biodiesel blends on Benzo[a]pyrene and main emissions using MOVES: A case study in Temuco, Chile

“…Several cities in the south of Chile have presented worse air pollution problems than Santiago, leading Temuco city and reaching the level of being considered non-attainment area for PM 10 for almost 10 years (Faiz et al, 1996;Díaz-Robles et al, 2008a;Sanhueza et al, 2009;Nicolas Schiappacasse Poyanco et al, 2013;Díaz-Robles et al, 2014) and since 2012 for PM 2.5 . The largest contribution of pollutants is due to the use of firewood as a fuel source in domestic heating, creating massive amounts of soot and air toxins.…”

“…Respiratory illnesses, cardiac, and cerebrovascular problems are some of the risks exposed to the populations of urban areas, such as in Santiago, Chile (Leiva et al, 2013;Díaz-Robles et al, 2014;Garcia-Chevesich et al, 2014). Economic development has generated an accelerated increment in industrialization and human activity, being considered one of the most polluted cities on a global level in the 80s (Escobedo et al, 2008).…”

Accuracy and reliability of Chile's National Air Quality Information System for measuring particulate matter: Beta attenuation monitoring issue

“…This site is widely used to develop several official reports as well as scientific studies about the state of the air quality, especially regarding PM concentrations. This information has been used in epidemiological studies (Díaz-Robles et al, 2014;Leiva G et al, 2013;Sanhueza et al, 2009), high pollution events forecasting (Cassmassi, 1999;Díaz-Robles et al, 2008;Perez and Reyes, 2006), studies concerning the relation between the chemical and physical compositions of PM (Morales and Leiva G., 2006;Morata et al, 2007;Toro A. et al, 2014), analyses of spatial and temporal trends (Gramsh et al, 2006;Morales and Leiva G., 2006;Toro A. et al, 2014), assessments of the cost and efficacy of prevention and decontamination measures (Silva and Quiroz, 2003;Toro A. et al, 2014). At a governmental level, the reports regarding the state of the air quality in Chile are noteworthy because the government's main objective is the enforcement of regulations, laws or international treaties signed by Chile.…”
