The purpose of this paper is to provide a summary of data on PAH content in soils in Poland, published in literature over the last 20 years. This paper presents a preliminary assessment of soil contamination by PAHs for different land use patterns. A review of available literature highlights the need to continue research on PAH contamination levels in environmental media in Poland, including surface soil. Results of such research would be important in order to better define exposure estimates in the general population and to examine the relationship between levels of PAHs in thc environment and thc subsequent development of health effects.

The PAHs content in four groups of meat products industrially and traditionally smoked was determined. Methodology applied for the study included fat’s extraction, PAHs isolation using GPC and consequently qualitative-quantitative compound’s determination by HPLC-FLD/DAD. Mostly traditional method of smoking affected the higher total PAHs contamination. For all products smoked using both methods it was proved that internal parts had a significantly lower total PAHs contamination as well as each individual PAH content than exteriors of the same products. Irrespectively of smoking method applied, benso[a]pyrene’s content was much lower than maximum tolerable limit of 5 μg·kg-1, which was set for smoked meat products in Commision Regulation (EC) No. 208/2005

In addition to the positive effects on the physical, chemical and biological soil properties of the application of sewage sludge into the soil, there is often an increase of both organic and inorganic pollutants in the soil. One of the most popular organic xenobiotics frequently present in sewage sludge are polycyclic aromatic hydrocarbons. The aim of this study is to determine possibilities for forecasting the content of individual PAHs in the soil on the basis of their content in sewage sludge. Two types of sewage sludge with different PAH contents, both in terms of quantity and quality, were examined. The different types of sludge were introduced into the soil in the following doses: 30, 75, 150, 300 and 600 t/ha. The results obtained showed a clear differentiation in the behaviour of individual PAHs in relation to the dose applied and the type of sewage sludge.

According to the Commission Recommendation 20005/108/EC further analyses of 15 genotoxic PAHs (listed by The Scientific Committee on Food) in food are necessary. The objective of this research was to study contamination of canned smoked fish products in oil by these 15 PAHs. The material investigated were canned smoked sprats in oil available in Warsaw agglomeration. Both oils from canned food and sprats itself were analysed. Among all products under investigation it was shown that oils derived from canned smoked sprats had statistically significant higher total content of PAHs than sprats from this canned fish product

Polycyclic aromatic hydrocarbons (PAHs) result from the incomplete combustion of natural or synthetic organic materials. The working environment at a coke plant can negatively affect the employed workers who were exposed to coke oven emissions containing PAHs, which formed and released into the environment by the process of pyrolysis of coke. This study aims to analyze the relationship between the exposure of PAHs and the risk of genetic damages such as chromosomal alteration (CA), micronucleus (MN), and DNA damage (PCR-RFLP) in peripheral blood lymphocytes of 27 coke oven workers and equal number of control subjects. The exposed subjects and controls were divided into two groups based on their age (group I<35 years and group II ≥35 years). The exposed subjects were further classified into two groups based on the exposure period (<12 years and ≥12 years). The frequencies of CA and MN in exposed subjects are relatively high with respect to controls. The XRCC1 399 Arg/gln polymorphism showed a substantial smaller difference in allele frequencies between exposed and control subjects. Based on present data, it was concluded that coke oven workers under risk should be monitored for adverse effects of the any long-term exposure.

One of the problems in an HPLC laboratory is the preservation of samples and extracts prior to analysis without any changes. It has been found that degradation processes cannot be eliminated entirely, but they can be slowed down considerably. Photodegradation kinetics of fluorene, anthracene and benzo(a)pyrene were studied in various organic solvents. Solvents known as good media to store PAHs for a long time were selected with respect to avoid degradation. In the case of fluorene, 9-fluorenone and 9-hydroxyfluorene were detected as main photoproducts. Formation of anthraquinone and 1,8-dihydroxyanthraquinone during the degradation of anthracene was observed. Benzo(a)pyrene-4,5-dihydrodiol and one of the isomers of hydroxy-BaP-dione as products of benzo(a)pyrene photodegradation have been identified.

Bitumens are produced and commonly used in paving, roofing and flooring operations, as well as corrosion-protective materials in Polish industry. During these processes bitumens, heated to the temperature range from 140°C to 200°C, emit multicomponent mixtures of toxic substances into the workplace air. Assessment of workers’ exposure to polycyclic aromatic hydrocarbons (PAHs) during road paving and production of roofing papers, asphalt-rubber blend and lute was the aim of this study. The results indicated that PAHs were detected in the breathing zone of all workers. Especially dangerous to human health was the process of roofing paper production. Exposure factors for PAHs (benzo [a] pyrene, benzo [a] anthracene, anthracene, dibenzo [a, h,] antracene, benzo [b] fluoranthene, benzo [k] fluoranthene, indeno [1,2,3-c, d] pyrene, chrysene, benzo [g, h, i] perylene) went up to 20.88 μg/m3.

The capacity of anthracene uptake by plants of two varieties of pea: Kwestor and Sześciotygodniowy, from soil and its effect on growth and development of the plants were determined in a model experiment. The anthracene levels applied were 0.1 and 0.3 g/kg of soil and its concentrations in the soil and the plants were determined with the absorption and emission spectrophotometry. After harvest, anthracene was present in all pea plant organs with its greatest amount in the roots. Depending on plant variety, age and the applied concentration of anthracene, changes in the stem and root length, biomass, and dry matter as well as the course of the proper leaf and nodule formation, were observed during the vegetation period.

Changes in cellular fatty acid composition during naphthalene degradation, at the concentrations of 0.5 g l⁻¹ or 1.0 g l⁻¹, by Pseudomonas sp. JS150 were investigated. In response to naphthalene exposure an increase in saturated/unsaturated ratio was observed. Additionally, the dynamic changes involved alterations in the contents of hydroxy, cyclopropane and branched fatty acids. Among the classes of fatty acids tested the most noticeable changes in the abundance of cyclopropane fatty acids were observed. Since day 4 of incubation these fatty acids were not dectected in bacterial cells growing on naphthalene. In contrast, markedly increased in the percentage of hydroxy fatty acids over time was observed. However, the proportions of saturated straight-chain and branched fatty acids did not change such significantly.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, and some are potent carcinogens in rodents. Carcinogenic PAHs are activated in the cells to metabolites that react with DNA to form covalent adducts. For most PAHs the reactive, electrophilic species which bind to DNA, are bay-region diol-epoxides. Application of 32-postlabeling to PAH-DNA adducts analysis revealed that for some PAHs the adduct profiles generated in model systems are more complex and include adducts which are more polar than those formed by classic bay-region diol-epoxides. This minireview summaries the information gained on typical representatives of polar PAH-DNA adducts. Formation of triol-epoxide-DNA adducts was proposed for chrysene and a non-alterant PAH, benzo[b]fluoranthene (B[b]F). 5-OH-B[b]F, the precursor of B[b]F triol-epoxide, was found to be a potent tumor initiator in mouse skin. For planar PAHs such as dibenzanthracenes the possibility of bis-diol epoxide-DNA adducts formation was suggested. The most comprehensive data were obtained for dibenz[a,j]anthracene (DB[a,j]A). This hydrocarbon when applied to SENCAR mouse skin forms up to 23 species of adducts, most of which are polar. Among these polar adducts seven were identified as derived from DB[a,j]A-3,4-10,11-bis-diol. Analysis of tumor-initiating activity showed, however, that this proximate metabolite was inactive in this respect. In contrast, an excellent correlation was observed between levels of less polar DNA adducts (i.e. those derived from bay-region diol-epoxides) and skin tumor initiating activity of DB[a,j]A. Thus, while triol-epoxides seems to be involved in tumor initiating activity of the parent compound, non alterant B[b]F, the significance of bis-diol epoxide-DNA adducts, at least those derived from DB[a,j]A, is minor.

A method for the preparation and application of aryl chemically bonded phases designed for SPE/HPLC determination of polycyclic aromatic hydrocarbons (PAHs) in environmental samples is described. New adsorbents have been characterised by different physicochemical techniques (porosimetry, CHN and chromatographic analysis). The sorption properties of prepared packings were investigated by the determination of sorption isotherms (so-called breakthrough curves). A comparison of the recovery rates (R) of selected PAHs for new packings and for conventional material C8 has been performed.

This paper presents the results of analysis of samples of river water and bottom sediments for PAH and PCB content using previously developed analytical procedures. Conclusions are drawn as to the form and main places of occurrence of the above analytes in the various elements of the river ecosystem (water phase, suspension, bottom sediments). The dependencies which were found between the PAH and PCB concentration in these three phases of the ecosystem suggest that: · PAHs are almost entirely adsorbed on the suspension and their transport in river water occurs mainly with the suspended matter. · PCBs are adsorbed to a lesser degree on the particles of suspended matter, which means that their transport in the river takes place both with the aqueous phase and with the suspended matter. · PAHs accumulate in bottom sediments to a much greater extent than PCBs.

Polycyclic aromatic hydrocarbons (PAHs) are more dangerous xenobiotics, very carcinogenic for animals and humans. They are found in air, water, sediments, and plant and animal tissues. most PAHs in the environment are derived during incomplete combustion of organic substances at temperatures lower than 700o C. total emission of all PAHs is very difficult to estimate but the global emission of benzo[a]pyrene is estimated at about 8600 tons/year. Most PAHs are lipophilic compounds that can be bioaccumulated to high levels. Microbial biodegradation and sunlight decomposition are the main mechanisms for PAH removal from sediments and water. In the present paper the authors will try to determine concentrations of 16 PAHs from the US EPA list in river water and drinking water of the ód area to be compared with bibliographic data obtained by other chromatographic methods.

TLC, GC and HPLC methods were employed to determine the concentrations of 16 PAHs in the surface level of soils subjected to a differentiated level of anthropopressure from the Poznan municipal area. PAH pollution was confirmed, primarily local pollution of soils at car and bus wash sites and fuel pumping stations and garden sites located in communal garden plots situated on previously recultivated areas. Research on such a broad scale was undertaken for the first time as well as a discussion in consideration of legal norms in force in Poland and worldwide. A low PAH level in the soils of the Poznan municipal area is confirmed by their biodegradation combined with the surface soil layer.
