“…Using Poisson regression and controlling for confounders, the authors concluded that the mortality increment associated with average PM 2.5 levels of 64 g/m 3 was 4.2%, and 4.3% for PM 10 -2.5 (daily average level of 47.3 g/m 3 ). In a cohort study of more than 504 infants younger than 4 months of age in the south of Santiago, Pino et al 50 analyzed the relationship between obstructive bronchitis and PM 2.5 . 50 The authors found that an increment of 10 g/m 3 of PM 2.5 was related to an increase of 5% (CI 0 -9%) of cases.…”

Temuco is one of the most highly wood-smoke-polluted cities in the world. Its population in 2004 was 340,000 inhabitants with 1587 annual deaths, of which 24% were due to cardiovascular and 11% to respiratory causes. For hospital admissions, cardiovascular diseases represented 6% and respiratory diseases 13%. Emergency room visits for acute respiratory infections represented 28%. The objective of the study presented here was to determine the relationship between air pollution from particulate matter less than or equal to 10 m in aerodynamic diameter (PM 10 ; mostly PM 2.5 , or particulate matter Ͻ2.5 m in aerodynamic diameter) and health effects measured as the daily number of deaths, hospital admissions, and emergency room visits for cardiovascular, respiratory, and acute respiratory infection (ARI) diseases. The Air Pollution Health Effects European Approach (APHEA2) protocol was followed, and a multivariate Poisson regression model was fitted, controlling for trend, seasonality, and confounders for Temuco during 1998 -2006. The results show that PM 10 had a significant association with daily mortality and morbidity, with the elderly (population Ͼ65 yr of age) being the group that presented the greatest risk. The relative risk for respiratory causes, with an increase of 100 g/m 3 of PM 10, was 1.163 with a 95% confidence interval (CI) of 1.057-1.279 for mortality, 1.137 (CI 1.096 -1.178) for hospital admissions, and 1.162 for ARI (CI 1.144 -1.181). There is evidence in Temuco of positive relationships between ambient particulate levels and mortality, hospital admissions, and ARI for cardiovascular and respiratory diseases. These results are consistent with those of comparable studies in other similar cities where wood smoke is the most important air pollution problem.

“…[2][3][4] These high levels pose a serious public health threat. [5][6][7][8][9] Individuals are exposed to air pollution while being outdoors or in various indoor microenvironments. Therefore, measuring air quality in homes, offices, or commercial buildings is very important because individuals spend most of their time indoors.…”

The impact of outdoor and indoor pollution sources on indoor air quality in Santiago, Chile was investigated. Toward this end, 16 homes were sampled in four sessions. Each session included an outdoor site and four homes using different unvented space heaters (electric or central heating, compressed natural gas, liquefied petroleum gas, and kerosene). Average outdoor fine particulate matter (PM 2.5 ) concentrations were very high (55.9 g⅐m Ϫ3 ), and a large fraction of these particles penetrated indoors. PM 2.5 and several PM 2.5 components (including sulfate, elemental carbon, organic carbon, metals, and polycyclic aromatic hydrocarbons) were elevated in homes using kerosene heaters. Nitrogen dioxide (NO 2 ) and ultrafine particles (UFPs) were higher in homes with combustion heaters as compared with those with electric heaters or central heating. A regression model was used to assess the effect of heater use on continuous indoor PM 2.5 concentrations when windows were closed. The model found an impact only for kerosene heaters (45.8 g m Ϫ3 ).

“…It is suggested that this synergistic effect is due to the carbon particles adsorbing SO 2 , which leaches off slowly, perhaps within macrophages, to recruit leucocytes in airways [19,34,35,36]. Epidemiological data addressing the role of air pollutants at usual levels can only suggest that some pollutants (Sulfur dioxide SO 2 suspended particulates) constituted a risk factor for respiratory infections.…”

“…apple juice which might precipitate asthmatic attacks [17]. Hajat et al, Aekplakorn et al and Pino et al studied the effects of fine particulate matter and wheezing illnesses in children and reported stronger effects for Sulfur dioxide (SO2), Nitrogen monoxide (NO) and Nitrogen dioxide (NO2) and concluded that air pollution in the form of fine particulates, mostly from vehicular exhaust might adversely affect infants respiratory health with potential for chronic effects later in life [20,36,37].…”
