    Comparison of indoor and outdoor air quality in latino communities in Peru, Chile, and USA
    (International Society of Indoor Air Quality and Climate, 2015) Champion, Wyatt M.; Barraza Saavedra, Francisco Javier; Jorquera, Héctor; Montoya, Lupita D.
    The air quality inside and outside the homes of three Latino communities (rural Peru, urban Chile and suburban USA) was compared in this study. Filter samples were collected and analysed for fine mass (PM2.5) and elemental and organic carbon (ECOC). An optical particle sensor was used in lieu of filter samples for PM2.5 mass in Peru. Results indicated that rural Peruvian homes burning dung for heating and cooking had the highest average level of PM2.5 indoors (140 μg/m3) and relatively clean outdoor air. Urban Chilean homes had a lower average indoor PM2.5 concentration (22 μg/m3), while suburban USA homes showed elevated concentrations of PM2.5 indoors (7.0 μg/m3) compared to outdoors, but lower indoor levels than the other two communities studied.

    Urban air pollution
    (Springer Cham, 2019) Jorquera, Héctor; Montoya, Lupita D.; Rojas, Néstor Y.
    Air pollution is currently the most serious environmental risk worldwide. Air pollution is the result of different driving forces (demography, economic growth, consumption patterns, energy options, cultural traditions, etc.) constrained by climate conditions, urban shapes and development patterns, distance to industrial or mining activities, air quality regulations and plans, etc. Air quality has been improving in some of the largest cities in Latin America, yet in most of them ambient air quality standards are not attained. In Brazil, Chile, Ecuador, and Mexico, the most polluted city is not the country’s capital, emphasizing the relevance of sustainable local governance. In countries that report air quality just for their capital cities, most of their pollution levels are above the respective national ambient air quality standards. There is less information for mid-sized cities, and the available results are mixed. We present case studies from several countries that show serious air quality exposure for millions of inhabitants, especially the low-income segment. We discuss environmental justice, urban governance, and citizen participation in decision-making processes, sustainable urban transport options, and gender issues throughout those case studies.
