Abstract	Maslačak (Taraxacum officinale Weber) rasprostranjena je višegodišnja biljka koja može reagirati na razna onečišćenja pa je zato dobar bioindikator. U ovom radu ispitivan je utjecaj antropogenih zagađivala na maslačak odnosno na sadržaj ukupnih topivih polifenola i askorbinske kiseline, koncentraciju proteina, klorofila i karotenoida te ukupnu antioksidativnu aktivnost. Kod uzoraka prikupljenih na prometnim lokacijama dolazi do smanjenja svih parametara u odnosu na uzorke prikupljene na lokacijama bez djelovanja prometa. Iz dobivenih rezultata možemo zaključiti da antropogena zagađivala negativno djeluju na ukupnu antioksidativnu aktivnost, pa samim time dolazi i do smanjenja sadržaja polifenola i askorbinske kiseline, koncentracije proteina, klorofila i karotenoida. Rezultat metode analize glavnih komponenata primijenjene na spektre dobivene metodom infracrvene spektroskopije s Fourierovom transformacijom (FTIR) ukazao je na razlike između uzoraka prikupljenih na prometnim i neprometnim lokacijama.
Abstract (english)	Dandelion (Taraxacum officinale Weber) is a widespread perennial plant that can react to various contaminants and therefore is a good bioindicator. In this paper, the influence of anthropogenic pollutants on dandelion, including the content of total soluble polyphenols and ascorbic acid, the concentration of proteins, chlorophyll and carotenoids and the total antioxidant activity was investigated. There is a decrease in all parameters in the samples collected at the location with the traffic in comparison to those collected at the location without traffic. From the obtained results we can conclude that anthropogenic pollutants have a negative effect on the overall antioxidant activity, and there is a decrease in the content of polyphenols and ascorbic acid, the concentration of protein, chlorophyll and carotenoids. The result of the principal component analysis method applied to the spectra obtained by the Fourier transform infrared spectroscopy (FTIR) indicated differences between the samples collected at traffic and non-traffic locations.
