Photochemical pollution precursors and ozone in the atmosphere of Cartagena from 1995-1997

摘要

This paper presents the results of two years monitoring photochemical pollution precursors in the atmosphere of Cartagena (Spain). Air quality parameters: Suspended particulate matter (SPM), SO_2, O_3, NO, No_2, methane hydrocarbons (MHC), non-methane hydrocarbons (NMC), and total hydrocarbons (THC), have been measured at five sampling stations. Analysis of variance has shown high spatial and temporal variability on these valuses at different sampling points. Meteorogical parameters from three meteorological towers have been also used to carry out correlation analysis with air quality parameters. A positive correlation beteen solar radiation and ozone, and between ozone and wind speed show the importance of long distance transport for photochemical pollution precursors.
