The goal of this work was the isolation of PCBs from different environmental matrices by means of solid-phase (SPE) extraction and gas chromatography/mass spectrometry (GC/MS). The analyses include the determination of PCBs in fourteen samples of transformer oils and different kinds of fodders (for poul­try, pigs, and cattle). The recovery rates for different congeners were on the level of 75-85%. The detec­tion limits of five congeners of PCBs were in the range 85 to 130 ug/kg. The RSD was on the level of 2.7 - 4.4%. The Ishikawa diagram was used for evaluation of uncertainty.

As people spend most of the time in closed spaces (flats, workplaces, schools etc.), the indoor air has been researched for many years all over the world. Particulate matter (PM) is one of the most often examined pollutants in the indoor and outdoor air. The following study presents the facts about PM in closed spaces and the most often taken actions. The least known aspects related to the indoor air pollution with PM are demonstrated. The indoor space of various service and office buildings/facilities (not related to production, i.e. offices, shops, beauty parlours, restaurant kitchens, restaurants, pubs etc.) seem to be an unrecognized area in the air pollution studies. Importantly, a great number of people work in such spaces all over the world and thus spend there a large part of their lives.

The distribution of polycyclic aromatic hydrocarbons (PAHs) in plant and organic soil from 14 peatland sites in NE Poland and 7 peatland sites in SE Poland have been investigated. The total PAH concentration in the leaves of Ledum palustre collected from peatlands in NE Poland ranged from 232 ng/g to 1523 ng/g and was higher than the total PAH concentration in pine needles (Pinus sylvestris) taken from those same peatlands (the values ranged from 181 to307 ng/g). A similar trend was observed in the case of plants from the peatlands in SE Poland, except that the overall PAH concentration in the majority of the plant samples was found to be higher than those found in NE Poland. Phenanthrene and fluoranthene had the biggest share in the overall PAH concentration in all the peat and plant samples. The lack of 5- and 6-ringed PAHs in the plant and soil material indicates the lack of any direct emission sources of these compounds in regions adjacent to those examined in the study. Total sum of PAH pollution levels in peats and plants as well as vertical distribution of the concentrations in the soil profile of particular study sites integrates long-range pollution sources. To compare natural and antropogenic PAH input in the pealtlands, we have used parent PAH ratios: ANT/(ANT&PHE); FLT/(FLT&PYR). Our data suggest that PAHs with four and more rings do not allow a simple segregation into combustion or petroleum sources.
