“…It is worth mentioning that in large cities, the use of firewood for heating reaches 79 %, while in smaller towns it reaches 98%. In addition, it can be seen that the highest concentration of households that consume firewood belong to a medium-low socioeconomic level (Bustos andFerrada 2017, Reyes et al 2020b)…”

Pollutant residential emissions from wood stoves have significant impacts both on the environment and people's health. The above makes it essential to know the types of volatile organic compounds emitted during combustion and explore their relationship with particulate matter and greenhouse gas emissions. This paper studies and analyzes these emissions using Eucalyptus globulus as fuel varying its moisture levels. Emissions were determined using an adapted commercial stove. The concentration levels of volatile organic compounds and particulate matter increase with the moisture of wood. When analyzing volatile organic compounds, particulate matter, and O 2 with the combustion stages of wood, it is found that their concentrations were higher in the ignition and the reload stage. The concentrations of CO 2 and NO x were higher in the reload stage. Other chemical compounds, such as toluene, xylene, and benzene, were also found within the volatile organic compounds listing, which increased their concentration in the ignition and stable reload stages. However, in the quenching stage, they are not present. Finally, the dispersion of these molecules in the environment is evaluated, obtaining that if the atmospheric conditions are adverse, these molecules remain in the environment in direct contact with the people living in those places.

“…Con respecto al ingreso, se demostró, en ambas estimaciones, que un mayor ingreso de los hogares incrementa probabilidad de consumir leña. Aun cuando el impacto fue bajo, es coherente con los últimos hallazgos para Chile (Bustos y Ferrada, 2017), pero no con la hipótesis de la escalera energética (Akther et al, 2010;Sgarbi et al, 2013), pues a partir de ella se debería esperar que los hogares con más ingresos buscaran sustituir leña por otros combustibles y, en consecuencia, disminuyera la probabilidad de utilizar leña.…”

“…Con relación a la sensibilidad de la demanda de leña frente a una variación del precio del gas, esta fue positiva, confirmándola como producto sustituto. Sin embargo, las estimaciones para precio del kerosene en el consumo de leña no fueron consistentes entre los modelos, situación que también se observa en el apartado precedente y que contradice la evidencia encontrada para Chile (Bustos y Ferrada, 2017).…”

“…Respecto al impacto de los precios de los bienes relacionados, Jaime et al (2020) indican la necesidad de profundizar en este tema en Chile. En un estudio para Osorno, una ciudad de Chile (Bustos y Ferrada, 2017), se concluye que el consumo de leña está explicado positivamente por el ingreso del hogar, el número de personas que lo componen y la edad del jefe de hogar; además, que las características de la vivienda, tales como el número de ventanas y de pisos (en niveles) inciden en forma inversa, así aquellas con 2 o más niveles reducen el uso de leña; finalmente, se señala que el kerosene y la leña se comportan como bienes relacionados.…”

La leña ha sido el dendroenergético más utilizado a escala residencial en regiones del centro y sur de Chile y su alto consumo en zonas urbanas ha afectado gravemente la calidad atmosférica. El objetivo de este trabajo fue analizar cómo factores económicos, sociodemográficos y características de la vivienda inciden en el consumo de leña de hogares en seis regiones del centro sur de Chile. Primero, se estudió el efecto en la probabilidad de consumir leña, mediante estimaciones logit y, luego, sobre la cantidad consumida con modelos Tobit, tanto para el área de estudio como por región. Se observó, a escala global, que aumentos en los ingresos del hogar incrementaron la probabilidad de consumir leña y las cantidades consumidas, siendo más fuerte el efecto en las cantidades. No obstante, el impacto entre regiones es muy distinto. Además, el consumo de leña disminuye frente a un aumento de su precio y aumenta ante el incremento del precio del gas siendo un bien sustituto. Aspectos sociodemográficos y características de la vivienda, como número de personas en el hogar, edad del jefe de hogar y superficie construida, se relacionaron positivamente con el consumo de leña. Los resultados contribuyen a formular políticas públicas regionales, de manera de enfrentar el problema planteado

Outdoor air pollution and biomass smoke exposure are related to the prevalence of chronic obstructive pulmonary disease (COPD). Since Osorno, Chile, is saturated with fine particulate matter (PM2.5), the aim of this work is to determine the prevalence distribution of COPD patients in the Primary Health Care (PHC) system in the city of Osorno, and its relationship with PM2.5. A cross-sectional descriptive study was carried out on COPD patients enrolled in the six PHC centers (PHCCs) of the city to assess the adjusted prevalence (population over 40 years). Gender- and territory-associated odds ratios (ORs) were also determined. In addition, an urban analysis of the distribution of PM2.5 and an exploratory analysis of the spatial behavior of enrolled COPD patients through featured binning were carried out. In 2018, the city of Osorno had 809 enrolled COPD patients in the PHC system (55.1% female), with a 1.3% age-adjusted prevalence (inhabitants over 40 years old), which was 11.7% after underdiagnosis correction. The COPD patients were mainly between 70 and 79 years old (34.3%). The urban area under the administration of the PHCC Rahue Alto (PHCC-RA) had a higher OR (1.98 [1.73–2.26]) compared to the situation of the city. Also, air pollution (PM2.5) was the highest in the PHCC-RA area, which could account for the observed prevalence. The number of COPD patients in this area is the highest in the commune, which increases the risk of complications derived from the disease and air pollution. Thus, territories with the highest COPD prevalence have the largest OR, which could complicate patients’ condition due to the high levels of outdoor air pollution.
