This paper presents the results of research conducted on some samples with soil and cabbage taken from the vicinity of Olecko town (Suwałki, Gołdapia, Ełk, Giżycko) and containing polycyclic aromatic hydrocarbons (PAHs) with 16 aromatic rings, the research is a continuation of a detailed monitoring of progressing pollution in the Olecko region, the samples were taken in August 2006 from the place situated 10 m from a road, this place was at the same time a cabbage plantation, the highest concentration of PAHs (750 pg/kg s. m.) was found in the sample taken close to the road from Olecko to Suwałki and in the sample with cabbage (313 pg/kg s. m.) taken near the road to Gołdapia. The lowest concentration of PAHs was stated in the samples taken in the vicinity of the road to Giżycko, the results don’t overpass the limits permitted in Poland but, unfortunately, are close to the upper limit of natural concentration defined by scientific literature.

Objectives 1-hydroxypyrene is an important biomarker of exposure to polycyclic aromatic hydrocarbons (PAHs), which appears in the urine of exposed human subjects. In developing countries, where advanced instruments are not available, the importance of this biomarker demands convenient and sensitive methods for determination purposes. This study aimed at developing a methodology to quantify 1-hydroxypyrene (a biomarker of PAHs exposure) based on the UV-visible detector in the reverse phase high pressure liquid chromatography (HPLC). Material and Methods A 20 μl injection of sample was used for manual injection into the HPLC Shimadzu, equipped with the SPD-20 A UV-visible detector, the LC-20AT pump and the DGU-20A5 degasser. The C-18 column was used for the purpose of the analysis. Results The method showed a good linearity (the range: R² = 0.979–0.989), and high detectability up to the nmol level. The average retention was 6.37, with the accuracy of 2%, and the percentage of recovery remained 108%. The overall performance of this method was comparable (in terms of detection sensitivity) and relatively better than previously reported studies using the HPLC system equipped with the UV-detector. Conclusions This method is suitable and reliable for the detection/quantification of the 1-OHP in human urine samples, using the UV-detector, however, it is less sensitive as compared to the results of a florescence detector.

Background: The article presents the results of the determination of polycyclic aromatic hydrocarbons (PAHs) in the fine particles fraction emitted from 3 types of diesel fuels using ultra-high pressure liquid chromatography. Material and Methods: Samples of diesel Eco, Verwa and Bio exhaust combustion fumes were generated at the model station which consisted of a diesel engine from the 2007 Diesel TDI 2.0. Personal Cascade Sioutas Impactor (PCSI) with Teflon filters was used to collect samples of exhaust fume ultrafine particles. PAHs adsorbed on particulate fractions were analyzed by ultra-high pressure liquid chromatography with fluorescence detection (UHPLC/FL). Results: Phenanthrene, fluoranthene, pyrene and chrysene present the highest concentration in the particulate matter emitted by an engine. The total contents of fine particles collected during engine operation on fuels Eco, Verwa and Bio were 134.2 μg/g, 183.8 μg/g and 153.4 μg/g, respectively, which makes 75%, 90% and 83% of the total PAHs, respectively. The highest content of benzo(a)pyrene determined in particles emitted during the combustion of fuels Eco and Bio was 1.5 μg/g and 1 μg/g, respectively. Conclusions: The study of the PAH concentration in the particles of fine fraction below 0.25 μm emitted from different fuels designed for diesel engines indicate that the exhaust gas content of carcinogens, including PAHs deposited on particulates, is still significant, regardless of the fuel. Application of ultrahigh pressure liquid chromatography with fluorescence detection for the analysis of PAHs in the particles emitted in the fine fraction of diesel exhaust allowed to shorten the analysis time from 35 min to 8 min.

Wstęp: W artykule przedstawiono wyniki oznaczania zawartości wielopierścieniowych węglowodorów aromatycznych (WWA) we frakcji cząstek drobnych emitowanych z 3 rodzajów paliw diesla z zastosowaniem ultraszybkiej chromatografii cieczowej. Materiał i metody: Próbki spalin diesla Eco, Verwa i Bio wytwarzano na modelowym stanowisku, które składało się z silnika wysokoprężnego – Diesel 2.0 TDI z 2007 r. Próbki cząstek drobnych spalin pobierano, stosując próbniki Personal Cascade Sioutas Impactor (PCSI, Indywidualny Impaktor Kaskadowy) z filtrami teflonowymi. Analizę WWA osadzonych na cząstkach stałych spalin prowadzono metodą ultraszybkiej chromatografii cieczowej z detekcją fluorescencyjną (ultra-high pressure liquid chromatography with fluorescence detection – UHPLC/FL). Wyniki: Fenantren, fluoranten, piren i chryzen niezależnie od zastosowanego paliwa obecne były w największych stężeniach w przeliczeniu na masę cząstek stałych emitowanych z silnika. Ich sumaryczna zawartość w cząstkach drobnych zbieranych podczas pracy silnika na paliwie Eco, Verwa i Bio wynosiła odpowiednio 134,2 μg/g, 183,8 μg/g i 153,4 μg/g, co stanowi 75%, 90% i 83% całkowitej zawartości WWA. Największą zawartość benzo(a)pirenu oznaczono w cząstkach emitowanych podczas spalania paliwa Eco i Bio, odpowiednio: 1,5 μg/g i 1 μg/g. Wnioski: Wyniki badań zawartości WWA w cząstkach drobnych frakcji poniżej 0,25 μm emitowanych z różnych paliw przeznaczonych dla silników Diesla wskazują, że mimo wymagań Normy Euro 5 zmniejszenia całkowitej emisji cząstek w spalinach zawartość substancji rakotwórczych, w tym WWA osadzonych na cząstkach stałych, wciąż jest znacząca, niezależnie od paliwa. Zastosowanie UHPLC/FL do analizy WWA w cząstkach frakcji drobnej emitowanej w spalinach diesla pozwoliło skrócić czas analizy z 35 min do 8 min. Med. Pr. 2014;65(5):601–608
