The aims of this study were to determine in-vehicle carbon monoxide (CO) levels in major commuting modes in the Metropolitan Area of Mexico City (MAMC) and to identify the main factors affecting the variation in these CO concentrations. CO concentrations were measured inside public and private transport vehicles during the winter of 1991 in Mexico City. Measurements were taken along several com...

Alkyl and multifunctional nitrates (RONO2, 6ANs) have been observed to be a significant fraction of NOy in a number of different chemical regimes. Their formation is an important free radical chain termination step ending production of ozone and possibly affecting formation of secondary organic aerosol. 6ANs also represent a potentially large, unmeasured contribution to OH reactivity and are a ...

A brief description is given of the origins and evolution of seismic design codes and practices in Mexico. The Mexico City Building Code is more deeply examined since, for many years, it has been a reference document in Mexico for the drafting of most of the Mexican codes, which, by law, are of municipal competence. Problems related to the implementation of building codes in Mexico are discusse...

BACKGROUND Controlled exposures of animals and humans to particulate matter (PM) or ozone air pollution cause an increase in plasma levels of endothelin-1, a potent vasoconstrictor that regulates pulmonary arterial pressure. OBJECTIVES The primary objective of this field study was to determine whether Mexico City children, who are chronically exposed to levels of PM and O(3) that exceed the U...

OBJECTIVE To compare the incidence of type 2 diabetes between low-income Mexican-Americans residing in San Antonio, Texas, and low-income residents in Mexico City, Mexico. RESEARCH DESIGN AND METHODS Using data from the San Antonio Heart Study and the Mexico City Diabetes Study, we compared the incidence of type 2 diabetes in 35- to 64-year-old low-income Mexican-American residents of San Ant...

An extensive set of measurements was made in and around Mexico City as part of the MILAGRO (Megacity Initiative: Local and Global Research Observations) experiments in March 2006. Simulations with the Model for Ozone and Related Chemical Tracers, version 4 (MOZART4), a global chemical transport model, have been used to provide a regional context for these observations and assist in their interp...
