Calling for synergized strategies to monitor and mitigate urban air and noise pollution in low and middle-income countries
Long-term exposure to PM2.5 and cardiorespiratory mortality
Long-term exposure to the fine particulate matter (PM2.5) is a risk factor for cardiorespiratory mortality. However, little is known about its distribution and health impact in large cities in low-middle-income countries where population exposure has increased during the last decades. This ecological study evaluated the association between PM2.5 concentration and adult cardiorespiratory mortality at the intraurban census sector (CS) level of Colo…
The International Global Atmospheric Chemistry project comments on the revised WHO air quality guidelines
In September 2021, the World Health Organization (WHO) announced updated global air quality guidelines providing health-based targets for six key air pollutants [1]. The annual targets for pollutant concentrations were reduced fourfold for nitrogen dioxide (NO2) to 10 μg m−3 and by 50% and 25% respectively for the mass concentration of particles smaller than and equal to 2.5 μm (PM2.5) and 10 μm (PM10) to 5 μg m−3 and 15 μg m−3. New targets were …
Photochemical sensitivity to emissions and local meteorology in Bogotá, Santiago, and São Paulo
This study delves into the photochemical atmospheric changes reported globally during the pandemic by analyzing the change in emissions from mobile sources and the contribution of local meteorology to ozone (O3) and particle formation in Bogotá (Colombia), Santiago (Chile), and São Paulo (Brazil). The impact of mobility reductions (50%–80%) produced by the early coronavirus-imposed lockdown was assessed through high-resolution vehicular emission …
Short-Term Effects of Air Pollution on Respiratory and Circulatory Morbidity in Colombia 2011–2014
Few studies have been conducted on the effect of air pollution on morbidity in Latin America. This study analyzed the effects of air pollution on respiratory and circulatory morbidity in four major cities in Colombia. An ecological time-series analysis was conducted with pollution data from air quality monitoring networks and information on emergency department visits between 2011 and 2014. Daily 24-h averages were calculated for NO2, PM 10 , PM …
