Pollutant concentrtion in fog-water at Kopisty (1999 – 2004)
Fišák, Jaroslav ; Chaloupecký, Pavel ; Fottová, D.
In this contribution, results of our studies devoted to analyses of fog water samples collected at the meteorological observatory over the period of 1999 - 2004 are summarized. The study deals with the parameters: conductivity, acidity and following selected ions: NH4+, Na+, Ca2+, Mg2+, K+, F-, Cl-, NO3- and SO42-. Overall, the total concentration of selected ions was remarkably decreasing during the period 2000 - 2004. Specifically, we found out an increase in the cation fraction for NH4+ and Ca2+, and a decrease in the anion NO3- fraction in the mean annual sample.
