Analytical procedures for PAH and PCB determination in water samples - error sources
PublicationW pracy przedstawiono poszczególne etapy procedury analitycznej wykorzystywanej do oznaczania analitów z grupy WWA i PCB w próbkach wody. Pokazano jakie problemy występują podczas oznaczania wyżej wymienionych analitów i jaki mogą mieć wpływ na końcowy wynik analizy.

Sources of errors associated with the determination of PAH and PCB analytes in water samples
PublicationW pracy przedstawiono problemy związane z oznaczaniem analitów z grupy WWA i PCB w próbkach wody. Zidentyfikowano źródła błędów. Szczególną uwagę zwrócono na:- proces adsorpcji analitów na ściankach szklanych naczyń używanych w trakcie obróbki i przechowywania próbek,- wpływ etapu odparowywania nadmiaru rozpuszczalnika z ekstraktów na odzysk analitów,- wpływ materiału, z którego jest wykonana kolumienka ekstrakcyjna (szkła, polietylenu)...

Monitoring of organic pollutants in coastal waters of the Gulf of Gdańsk, Southern Baltic.
PublicationPrzedstawiono zmiany zawartości zanieczyszczeń organicznych (np. VOC, PAH, PCB, chlorofenoli) w wodach Zatoki Gdańskiej na przestrzeni 5-ciu lat. Zawartość VOX i VOC zmieniała się od kilku ngdm-3 do kilkuset ngdm-3, podczas gdy zawartość chlorofenoli fenoksykwasów była na poziomie kilku ngdm-3. W większości próbek nie wykryto PCB.

Organic Pollution in Surface Waters from the Fuglebekken Basin in Svalbard, Norwegian Arctic
PublicationThe Fuglebekken basin is situated in the southern part of the island of Spitsbergen (Norwegian Arctic), on the Hornsund fjord (Wedel Jarlsberg Land). Surface water was collected from 24 tributaries (B1-B24) and from the main stream water in the Fuglebekken basin (25) between 10 July 2009 and 30 July 2009. The present investigation reveals the results of the analysis of these samples for their PAH and PCB content. Twelve of 16 PAHs...

Contamination of Runoff Water at Gdańsk Airport (Poland) by Polycyclic Aromatic Hydrocarbons (PAHs) and Polychlorinated Biphenyls (PCBs)
PublicationAirport runoff can contain high concentrations of various pollutants, in particular polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), the environmental levels of which have to be monitored. Airport runoff water samples, collected at the Gdańsk-Rębiechowo Airport from 2008 to 2009, were analysed for PAHs and PCBs by gas chromatography. The aromatic fractions were separated by liquid-liquid extraction...

Polychlorinated biphenyls (PCBs) in bottom sediments: Identification of sources
PublicationPolychlorinated biphenyls (PCBs) can enter the environment from various sources. They are synthetic chemicals and as such are present in the environment mainly as mixtures containing various amounts of PCB congeners. It is therefore difficult to pinpoint the source of PCB emissions into the environment and the pathways along which they migrate there. The situation is different where locating the emission sources of polycyclic aromatic...

Removal of persistant organic pollutants from landfill leachates treated in three constructed wetland systems
PublicationThe objective of the study was assessment of occurrence and removal of two groups of persistent organic pollutants: polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in landfill leachate (LL) treated in three constructed wetland systems (CWs) of different construction and flow regime. Two subsurface flow systems (SSF) were analyzed: one with horizontal flow and the second one consisting of two vertical...

Polychlorinated Biphenyls (PCBs) and Polycyclic Aromatic Hydrocarbons (PAHs): Sediments and Water Analysis
PublicationUnfavorable side effects of different forms of anthropogenic activities can be found anywhere in the world. One of the basic characteristics of pollutants entering marine and ocean waters is their spread and movement in the global ocean. A portion of the substances entering the marine environment is rapidly degraded by chemical processes occurring in the air, sediments, and water, thereby losing their toxic properties. The biggest...

Impact of pollution derived from ship wrecks on the marine environment on the basis of s/s ''Stuttgart'' (Polish coast, Europe)
PublicationW 1943 roku niemiecki statek szpitalny, s/s Stuttgart (Lazaretschiff ''C'') został zatopiony w pobliżu portu w Gdyni. Doprowadziło to do zanieczyszczenia dna morskiego paliwem. Podczas badań przeprowadzonych w 2009 r. pobranych zostało 11 próbek osadów powierzchniowych i wody morskiej oraz 4 rdzenie. Próbki poddano analizie na zawartość zanieczyszczeń priorytetowych należących do grupy wielopierścieniowych węglowodorów aromatycznych...
