Mexico: High air pollution in Mexico City

Event

High levels of air pollution (ozone) have been reported in parts of the Mexico City region since October 26 and are expected to remain high throughout the Valle de México until at least Sunday, November 5. Particularly poor air quality has been detected in the Coyoacán, Álvaro Obregón, and Benito Juarez areas.

This pollution could cause headaches and eye, nose, and throat irritation as well as aggravate cardiovascular and respiratory conditions (such as asthma). The government is advising individuals to avoid outdoor activities between 15:00 and 17:00 (local time) when pollution levels tend to peak. Particularly vulnerable groups include children, the elderly, pregnant women, and people with chronic illnesses.

Context

Being in Mexico City during days of “bad” pollution levels, of which there were 212 in 2016, is reportedly the equivalent of smoking 40 cigarettes per day. More than 9000 people are estimated to die prematurely each year in the capital region due to these high pollution levels.

Advice

Individuals present in the Mexico City region are advised to keep abreast of air quality levels and to limit outdoor activities until the situation normalizes.
