Evolution of anthropogenic aerosols in the coastal town of Salina Cruz, Mexico: Part II Particulate phase chemistry

Popis výsledku v původním jazyce

An analysis of atmospheric gases and particles during periods of land and sea breezes in a coastal city in southwest Mexico indicates limited removal of total particle mass by deposition during periods when the air resides over the ocean. The average PM2.5 mass concentrations for land and sea breeze samples were 25 and 26 ug/m3, respectively. The average sum of the ion concentrations (NH4, SO4, NO3, Na, Cl) were 10 and 11.8 ug/m3 for the samples taken during land and sea breeze periods. The average total carbon concentrations were 6.0 and 5.3 ug/m3 for land and sea breeze periods. The mass of sulfate in particles of ocean origin, 3.3 ug/m3, is marginally higher than those originating from the land, 2.0 ug/m3, presumably as a result of the conversion ofSO2 recirculated from the city. The fraction of sulfate, nitrate and ammonium ions in rainwater samples is almost a factor of two higher than the fraction measured on filtered air samples.
