摘要

Mexico City is a densely populated megacity with average PM10 and PM2.5 levels frequently above those indicated as health-threatening for humans by the World Health Organization. Polycyclic aromatic hydrocarbons (PAH) can be emitted by anthropogenic sources as the result of the incomplete combustion of organic matter and fossil fuels and they represent an important risk for human health under poor air quality conditions. High concentrations of PAHs have been linked with cancer and other respiratory diseases. Particle-bound PAHs (PPAHs) have been previously studied in Mexico City; however, their temporal scales are not fully understood given the short sampling periods (no more than five weeks) during which time they were evaluated.
