Impacto de la contaminación por material particulado sobre las atenciones de urgencias por causas respiratorias en Chillán, Concepción y Los Ángeles

Abstract

Impact of pollution by particulate matter on emergency room admissions for respiratory causes in Chillán, Concepción, and Los Ángeles, Chile Objective: To determine the impact of air pollution on respiratory diseases in the districts of Chillán, Concepción and Los Ángeles, Chile between 2013 and 2017. Material and Methods: Generalized linear models (GLM) were estimated from daily data for emergency room admissions disaggregated by type and age range, concentrations of respirable particulate matter (PM 10) and fine particulate matter (PM 2.5), viral index, meteorological and seasonal variables. Results: A positive association is obtained between the analyzed contaminants and the number of emergency room admissions for respiratory causes, especially acute upper respiratory infection (URI) and acute bronchitis / bronchiolitis in Chillán, acute URI in Concepción, and also, acute URI, Influenza and obstructive bronchial crisis in Los Angeles. Conclusions: The increase in the total number of emergency room admissions is approximately 18,695 per year for every 1 μg / m 3 increase in PM concentrations.

Assessment of Short-Term Effects of Heat Waves and Warm Days on Human Health in Santiago-Chile.

“…In this way, GAM is a powerful tool because it ts timescale trends such as long-term and can be used to estimate the impacts of HW and WD exposure and identify vulnerable areas. In Chile, some of these models have been used, but use is more widespread in the risk assessment of primary contamination (Sanhueza et al 2006); (Mardones et al 2015); (Remaggi S. et al 2019) with scarce evidence in risk assessment of mortality and morbidity by causes or age for HW exposure. Therefore, further research is necessary to estimate the risk of morbi-mortality for exposure to HW and WD.…”

De la protesta a la propuesta: creatividad territorial como dispositivo metacognitivo en una propuesta de educación popular ambiental desde la Región del Biobío, Chile

“…En la misma línea, la campaña "Que tu huella sea positiva" (Ministerio de Medio Ambiente de Chile, 2020) pretendiendo adaptarnos al cambio climático, propone medidas individuales para detener incendios forestales, como manejo de fogatas, y no interpela a la industria forestal sobre disminución de densidades, uso de cortafuegos o planificación por cuenca. También propone medidas para reducir plásticos desechables e incentivar el reciclaje, haciendo caso omiso a las tasas de producción de material particulado de las industrias y los niveles de saturación atmosférica (Remaggi et al, 2019).…”
