Air pollution in latin america
Chile: santiago: highest pollution level in the
According to the World Health Organisation, air pollution is the most serious environmental threat to human health in the Americas. This year’s World Environment Day theme is Air Pollution, and the opportunity to raise awareness about the issue could not come at a better time for Latin America.
Wildfires erupted through most of Mexico only a few weeks ago, burning nearly 849,000 acres in 32 different jurisdictions from January to May, causing severe air pollution. As a result, air quality in Mexico reached unsafe levels in many states, schools were closed, and residents were urged to remain indoors.
At the same time, Chile, on the other end of Latin America, is gearing up for winter, the time of year when air pollution is at its worst due to the widespread use of wood in homes and other buildings for heating and cooking. As a result, cities in central and southern Chile usually have some of the poorest air quality in the Western Hemisphere. Due to high levels of fine particulate matter in the air, ten million Chileans live in areas classified as “saturated.”

The first multicity analysis to estimate the impact of short-term exposures to particulate matter (PM10) and ozone on mortality in nine Latin American cities is described in this paper. The researchers used a similar analytic method to assess mortality from all causes and in various age groups, led by Dr. Isabelle Romieu in Mexico, in collaboration with Dr. Nelson Gouveia in Brazil and Dr. Luis Cifuentes in Chile. They looked at mortality in each city and the area as a whole, as well as two different pollutant models in each city. To delve deeper into the impact of individual cities, they used two meta-analytic statistical techniques.
Air pollution has a high societal cost. Each year, air pollution is estimated to cause 500,000 to 1 million premature deaths worldwide, with costs totaling around 2% of global GDP (GDP). Outdoor air pollution is projected to cost about 1% of national GDP in Colombia, Peru, Guatemala, and El Salvador, according to recent Bank reports. The social costs of all environmental impacts total US$3.8 billion, according to a recent World Bank report of six cities in developing countries, with health impacts accounting for 68 percent. According to recent estimates by the Pan American Health Organization (PAHO), more than 100 million people in Latin American cities are exposed to air pollution levels that surpass prescribed limits. Furthermore, according to the World Health Organization’s Global Burden of Disease Report (2002), outdoor air pollution causes 35,000 premature deaths and 276,000 years of life wasted per year in Latin America (adjusted by disability).

The release of many contaminants into the environment that are directly or indirectly harmful to living beings is referred to as air pollution (Mackenzie 2016). About 91 percent of the world’s population lives in places where air pollution levels meet WHO guidelines (WHO 2018). As a result of growing industrialization and urbanization, air pollution has become a major global concern in many urban societies around the world. Crops, animals, trees, and rivers are all harmed. It also contributes to the ozone layer’s depletion, which protects the earth from the sun’s UV rays.
Nitrogen (N), oxygen (O), carbon dioxide (CO2), sulfur dioxide (SO2), carbon monoxide (CO), ammonia (NH3), nitrogen oxide (NOx), particulate matter (PM), volatile organic compounds (VOC), and other gases make up the bulk of the climate (Karim et al. 2000; Hackstadt et al. 2014). Different forms of contaminants in the air, as well as unfavorable weather conditions, trigger air pollution (Papanastasioua et al. 2015). Various short-lived climate contaminants, particulate matter, and other pollutants are among these pollutants. Short-lived climate pollutants (SLCPs) are pollutants that linger in the environment for a short period of time and trigger climate change. Black carbon (BC), tropospheric ozone (O3), and methane are the main SLCPs (CH4). Mexico City (Mexico) is the largest source of SCLPs in Latin America (UNEP 2015). Hydrofluorocarbons (HFCs) are also responsible for emissions in the air. It’s a common ingredient in refrigeration and insulating foam (Molina et al. 2009). Another pollutant, BC, absorbs sunlight and melts ice and snow, contributing to global warming (Anenberg et al. 2012). LAC is responsible for 12% of the world’s overall BC emissions. In contrast to other greenhouse gases such as CO2, black carbon only stays in the atmosphere for a few days or weeks. As a result, lowering black carbon emissions provides almost immediate benefits.
