Geo-Mexico looks in some detail at air quality issues in several Mexican cities, focusing on trends in carbon monoxide, ozone and microparticulates (PM10) from 1995-2008. Among other things, it concludes that,
“As a result of aggressive government efforts, the quality of air in Mexico City has improved significantly. Since 1990 the number of hours that air pollution exceeded the city’s quality standard has declined by about two-thirds. Ozone continues to be a problem as do minute particulates under 10 microns (PM10), both of which can have serious health consequences.”

In the two years since 2008, the trend towards improvement of the air quality in Mexico City has continued according to this article which has appeared in numerous newspapers including the online version of The Independent, a UK daily.
That is very good news indeed. Hopefully air quality in all Mexico’s major cities will improve over the coming decade. When last we looked, Monterrey’s air pollution statistics were still headed in the wrong direction.
