Sažetak

In order to assess the situation with air pollution by ozone in Colorado region during sunny part of the year (April to September), recently introduced photochemical pollution (PP) indicators have been applied on acquired ozone data, i.e. hourly ozone volume averages. PP indicators show very low values at the majority of stations except for the two located in Denver and Arvada which are located in the centre of the highly populated area covered by this assessment. Some other stations (e.g. National Renewable Ener¬gy Labs) have somewhat high number of excess times during the growth period; total daily turnover of ozone is, however, rather low indicating absence of other photochemical pollutants (e.g. NOx) which, therefore, justify low values of PP indicators. Generally, our assessment method shows very low PP in the assessed area which is central, most populated part of the state of Colorado. (doi: 10.5562/cca2357)
