Abstract
This paper presents the results of the analysis of organic chemicals in different urban dusts. The aim of the research is preliminary evaluation of the presence of organic contaminants in household dust, attic dust and street sediment. Celje area has been chosen as a pilot study site due to availability of sampling materials from previous sampling campaigns. Samples have been tested to the presence of 120 organic Compounds. Attic dust contains 98 different organic Compounds or 82 % of all measured. Terpenoids, alkylbenzenes and different Polycyclic Aromatic Hydrocarbons (PAH's), as well as plasticizers, halogenated Compounds (among them also PCB's) and pesticides (DDT and degradation products) can be found there. It also contains all of the in this study analysed US-EPA priority pollutants. Street dust contained 70 different organic chemicals (58 %), among them 14 priority pollutants. Traces of aliphatic organic Compounds, PAH's, aldehydes and ketones, esters, and plasticizers are found there. House dust contains lowest number of organic Compounds. Among 45 detected (38 % of total measured), 8 are priority pollutants. Aliphatic Compounds, alkylbenzenes, aldehides, ketones, acids and PAH's can be found there. Current number of analysed samples, as well as only qualitative evaluations were made does not allow making any solid Interpretation of obtained results in regarding to the potential sources of chemicals or potential environmental hazards. This study can thus be used only as a guideline for future studies of organic chemicals in urban dusts.

Celje area is well known for its environmental contamination
This article presents the results of the chemical analyses of urban dusts in the Celje area by the means of gas chromatography / mass spectrometry
Sample in this study was collected in September 2001 in a building constructed in the beginning of 20 century, as a part of the other project, which aim was to evaluate the extent of toxic metal contamination in Celje area (Žibret, 2002; Šajn, 2005)
Summary
Celje area is well known for its environmental contamination. In the past studies main focus has been put on the evaluation of toxic metals contamination in soil due to past smelting and ironworking activities (Fran~i{kovi~-Bilinski et al, 2006; Le{tan et al, 2003; Lobnik et al, 1989; Šajn, 2005; Zupan et al, 2000; Žibret, 2002, 2008; Žibret & Šajn, 2008). Few researches have been done regarding the evaluation of organic pollutant contamination in the area, and even existing studies are focused mainly on the presence of very limited list of organic pollutants in drinking water. This article presents the results of the chemical analyses of urban dusts in the Celje area by the means of gas chromatography / mass spectrometry.
