Abstract

Since 2004, continuous measurements of hydrogen sulphide (H2S), ammonia (NH3), and mercaptan (R−SH) levels in air have been monitored in the area of the Central wastewater treatment plant Zagreb (CUPOVZ). At two measuring sites within the CUPOVZ area, Biology-north and Biology-south, for a month in every season in 2017, twenty-four hour samples of H₂S, NH₃, and R−SH were collected. Measured concentrations of gaseous pollutants showed statistically significant seasonal variations (p < 0.05) at both measuring stations. For the overall period, high positive correlations were found between all pollutants and temperature, and negative with pressure.
