| Popis: | Mjereno je 12 policikličkih aromatskih ugljikovodika u uzorcima lebdećih čestica uzorkovanim u središnjem dijelu Zenice svaki treći ili četvrti dan tijekom cijele godine. Koncentracije su posebno visoke zimi, kada su uz stalnu industrijsku emisiju prisutne i emisije iz kućnih ložišta, a zbog klimatskih i orografskih uvjeta češće dolazi do temperaturne inverzije. Profili, tj. omjeri policikličkih aromatskih ugljikovodika prema benzo-a-pirenu ne variraju mnogo u ovisnosti o godišnjem dobu osim fluorantena i pirena. Srednje godišnje vrijednosti mjerenih policikličkih aromatskih ugljikovodika su više (omjer zimskih i ljetnih koncentracija niži) u odnosu na područja gdje ne postoji stalan izvor njihovih emisija. Twelve polycyclic aromatic hydrocarbons were measured in samples of airborne particles collected in the town of Zenica in the Republic of Bosnia and Herzegovina every third or fourth day throughout the year. The concentrations were especially high in winter when in addition to permanent industrial emissions those from individual heating systems were also present and when owing to climatic and orographical circumstances temperature inversions occurred more frequently. The profiles of polycyclic aromatic hydrocarbons i.e. their ratios to benzo-a-pyrene did not demonstrate great seasonal variations with the exception of fluoranthene and pyrene. The mean annual concentrations (winter to summer concentration ratios) were higher than in the areas where there was no permanent source of emissions. |
