Resumen o descripción

The BC and PM2.5 concentrations in Guadalajara, Mexico were measured in 2008 using a two–wavelength

Aethalometer!and a Partisol sampler, respectively. The aerosols were collected within two sites of the local!Network

Monitoring Stations, Centro in downtown!and Miravalle in the south. BC was measured from January to December

and PM2.5 from January to August. The 24–h PM2.5 mean concentrations were 73 and 90μg!m"3 at Centro! and

Miravalle,respectively. Mexican air quality 24–h!standard (65μg!m–3) was exceeded by 79% of the PM2.5 samples. The

BC study period was divided into three seasons: two dry seasons (DS1 and DS2) and one rainy season (RS). The hourly

BC median concentrations at Centro!and Miravalle were 1.3–8.7 and 1.5–13.8μgm"3 in DS1 while 1.4–3.3 and 1.9–6.4

μg!m–3 in RS, and 1.4–7.0μg!m"3 in DS2. When the 24–h mean BC concentration is compared to the mass

concentration on PM2.5, it shows that BC comprises less than10% of!the fine particles measured at!the same period.

Considering the meteorological parameters wind speed and wind direction, data analysis indicates that the BC

concentration is mainly influenced by local sources at Centro, but by regional and/or long–range transport and local

sources at Miravalle site. The strong correlation between BC and carbon monoxide concentrations confirmed that

these two species at the two sites have common sources.
