Anion concentration assessment in bulk precipitation samples collected in San José, Costa Rica. Part I

Measurement of SO4-2, NO3-, Cl-, NO2-, Br-, PO4-3, conductivity and pH was performed on bulk precipitation samples collected at six sites in San José City, Costa Rica, from July to November, 2006. 45 % of the samples presented a pH value between 4.0 and 5.6, while only 26 % of them were basic. Two f...

Sumario:Measurement of SO4-2, NO3-, Cl-, NO2-, Br-, PO4-3, conductivity and pH was performed on bulk precipitation samples collected at six sites in San José City, Costa Rica, from July to November, 2006. 45 % of the samples presented a pH value between 4.0 and 5.6, while only 26 % of them were basic. Two factors were found after a principal component analysis was applied to results. Factor 1 indicated a contribution of anthropogenic sources for NO3- and NO2-. Factor 2 indicated a possible contribution of anthropogenic and sea sources for SO4-2 and Cl-.
