First measurements of carbon tetrachloride and tetrachloroethene in the atmosphere of Athens, Greece

Levels of carbon tetrachloride and tetrachloroethene were determined for the first time in Athens in the summer of 2000. The mean CCl4 and C2Cl4 concentrations were 0.060 and 0.18 ppb, respectively. CCl4 did not exhibit significant variation throughout the measurement period or with wind direction. C2Cl4 under strong eastern winds had less than half the concentrations observed during other meteorological conditions. No diurnal variation was observed for either compound.
