Fifteen polycyclic aromatic hydrocarbons (PAHs) were measured in the spider webs prepared in the laboratory and exposed to indoor air pollution in a defined period of time. We have selected homes differing in location (rural area vs. city), type of room (living room, kitchen, basement), inhabitant's habits (smoking cigarettes vs. non-smoking) and type of heating/cooking devices used (natural gas, liquefied gas, coal- and wood-fuelled heating). Webs from two species, from Agelenidae and Pholcidae families, were prepared and used for monitoring of PAHs. PAHs were characterised based on concentration, profile distribution, source apportionment by cluster analysis and diagnostic ratios. The concentrations of sum of 15 PAHs (mu g g(-1) dry weight) varied from 1.7 (bedroom in detached house in rural area) to 67.9 mu g g(-1) (room with heavy smokers in detached house in the city), and were dominated by 3-ring (6.89-57.1%) and 2-ring compounds (5.05-48.3%). The result of cluster analysis (CA) suggested two distinct groups of PAHs. The dominant PAH source was found to be mixed petrogenic and pyrogenic consisting of a mixture of cooking, smoking, heating and neighbouring traffic activities. (C) 2018 Elsevier Ltd.
