Resumen:

Monterrey, the capital of the state of Nuevo Leon, is the most important industrial city in northeastern Mexico. Air quality presents a serious problem in Monterrey. The present study focuses on one aspect of air pollution, the chemical composition of rainwater. The chemical composition of the rainwater varies from region to region, due to the influence of different sources. If the source is influenced by anthropogenic activities, rainwater chemistry will reflect anthropogenic activities contributing gases like SOx and NOx and basic gases like NH3. The sampling period was from June to September 2006. The station is located on the roof of the Chemistry Department at the University of Nuevo Leon, an area in the north of Monterrey where most of pollution is generated. Samples of wet, dry and bulk rainwater were collected and analyzed for PH, ion concentrations (SO42-, NO3-, Cl- Ca2+, Na+, K+) and conductivity. The results show that the average pH is higher than 6. The conductivity and ionic concentrations decreased throughout the course of rainy season. The results of this research will be use to evaluate atmospheric deposition, evaluate air quality and to develop strategies to implement preventive measures and control of the atmospheric emissions in this State. The present work represents the first study of rainwater chemical composition in the Northeast of Mexico. © 2007 by the Air & Waste Management Association.
