Detailed explanation-1: -Among the worst hazards of that air pollution for its 21 million inhabitants is PM 2.5, inhalable fine particulate matter. People exposed to PM 2.5 can suffer from coughing, shortness of breath, bronchitis, respiratory infections and heart problems.
Detailed explanation-2: -Located in the crater of an extinct volcano, Mexico City is about 2, 240 metres above sea level. The lower atmospheric oxygen levels at this altitude cause incomplete fuel combustion in engines and higher emissions of carbon monoxide and other compounds. Intense sunlight turns these into higher than normal smog levels.
