Sulfate, nitrate and chloride in PM10 in the city of San José, Costa Rica: 2004-2006

The analysis of PM10 levels in two sites of the city of San José (Catedral Metropolitana and Junta de Educación), in a period of 2.5 years (April 2004-October 2006), reported a median of 39 ± 8 and 27 ± 8 ¿g m-3, respectively. In addition, SO42-, NO3- and Cl- levels were measured in both areas, wher...
