On March 6, environmental pollution in Medellín, Colombia, triggered the highest alert levels. For three days, industrial production and driving restrictions (locally known as pico y placa) have been tightened. According to specialists consulted by the local newspaper El Tiempo, meteorological conditions are expected to make the situation “most critical” in two weeks.
In light of situations like this, air quality monitoring and control have taken on greater importance in Colombia. This is especially critical given that one in eight deaths worldwide is caused by air pollution, according to figures from the World Health Organization (WHO). In Colombia, 10,527 deaths and 67.8 million cases of related symptoms and illnesses occurred in 2015, as reported in 2017 by the National Planning Department following a study on the health costs of environmental degradation.
