Composition of wastewater is complicated. It is rich in micro- and macroelements, plus many carbon species. During wastewater treatment carbon changes chemical form and creates sewage sludge as a by-product. Sewage sludge is rich in nutrients and organic compounds, and possesses a potential soil-forming value. Hence it can improve soil properties, especially when applied to poor sandy soils or sludge. The last part of carbon changes occur in soil when organic matter is produced across specialized microorganisms. The aim of our current work is to present the main carbon fractions in three environmental matrices: wastewater, sewage sludge, and soil.

Crop models use mathematical equations to simulate the physical and chemical processes that generally control the uptake, translocation, and sorption of xenobiotics in all part of plants. Each compartment is anatomically characterized and described by a series of mathematical equations. Sample preparation, such as liquid extraction methods and solid-phase-based methods are presented. Analysis of xenobiotics are generally carried out by gas chromatography (GC) or liquid chromatography (LC) coupled to different detectors, especially to mass spectrometers (MSs) and hyphenated techniques that have become extremely developed in recent years. As an example the wheat plant, as a model to describe xenobiotic uptake by roots and sorption of xenobiotic in grain, is applied.

A new technique for sample preparation, Solid Phase Microextraction (SPME), is described. Theoretical and practical aspects and the particular possibility of using this technique in environmental analyses are discussed (application for analytical determination in different matrix). This paper will show many advantages as well as faults of SPME.

A study was carried out on the sorption of the sparingly water-soluble pesticide linuron in various types of soil with different levels of organic matter. The sorption isotherms of the pesticide were obtained in bathequilibrium experiments and the data were fit to Freundlich and Dual Reactive Domain Models. In general, the sorption was the highest for the soil with greatest content of soil organic matter. The study also points out the global problem of handling the sewage sludge at wastewater treatment plants. We studied the compost made in Torun's Wastewater Treatment Plant during sludge fermentation. To characterise the compost organic matter UV-Vis and 13C CP/MAS NMR spectroscopy were used. Consequences of the compost use in agriculture are also discussed here. Particular attention is given to the changes in the behaviour of pesticides applied to soil in the presence of compost organic substances. The treatment of soils by the compost from sewage sludge may lead to increased retention or removal of hydrophobic compounds like linuron.

Method for determination of carbendazim residues in fruits, vegetables and cereals was described. The compound was extracted with methanol-hydrochloric acid mixture, and after liquid-liquid partition step with dichloromethane, was determined by high performance liquid chromatography (HPLC) with column switching and ultraviolet (UV) detection. The average recoveries of carbendazim from fortified sample were from 68.7% ± 4.3% to 92.6% ± 4.5%, the coefficients of variation were from 2.9% to 6.3%, and the limits of quantification at λ = 279 nm were from 0.02 mg/kg to 0.2 mg/kg.

The aim of this study was to optimize of a method for determining of compounds which are responsible for the earthy/musty odour in surface water. Among taste and odour contaminants the following compounds are mentioned: (+/-)-geosmin, 2-methylisoborneol, 2,4,6-trichoroanisole, 2-isopropyl-3-methoxypyrazine and 2-isobutyl-3-methoxypyrazine. Some experiments were performed to examine the extraction conditions such as fiber exposure time, temperature of extraction and salt addition. Various SPME fibers such as PDMS, CAR/PDMS and PDMS/DVB coatings were used for the isolation of tested compounds from water samples. As tested, compounds 2-methylisoborneol, 2-isopropyl-3-methoxypyrazine and 2-isobutyl-3-methoxypyrazine were used. After SPME optimization, real surface water samples were examined using the SPME-GC/MS method. Based on preliminary experiments the qualitative and quantitative analyses for the determination of (+/-)-geosmin, 2-methylisoborneol and 2,4,6-trichloroanisole were performed. The regression coefficients for calibration curves for examined compounds are R²≥0.990. This shows that the used method is linear in the examined concentration range (from 20.32 to 168.00 ng/L). one of the reasons for the formation of taste and odour contaminants can be surface water pollution. The changes of water conditions such as temperature, pH and conductivity were examined. And, for the test of periodical changes of geosmin concentration in surface water samples, the experiments were performed in various seasons.

Soils and ground waters have been extensively exposed to pollution by heavy metals from various anthropogenic sources. The presence of these metals in soils poses a significant environmental hazard, and one of most difficult contamination problems to solve. Description of some sorption and migration phenomena involving Pb, Zn, Ni and Cu in the surface layer of soil and sewage sludge compost was the primary objective of this work. A wide range of pH (3.0 - 5.5) of simulated acid rains, used to study the elution of metals from these matrices allowed a qualitative description of these metals' behaviour.

In this paper physical, chemical and toxical properties of the polycyclic aromatic hydrocarbons (PAHs) have been described. Different methods for isolation of these compounds from air, water and soil were presented. Various chromatographic methods such as gas chromatography (GC and CGC/MS), high performance liquid chromatography (HPLC) with UV-Vis, diode array and fluorescence detection, thin-layer chromatography (TLC) and supercritical fluid chromatography (SFC) were applied for PAH determination.

In the current contribution, the application of the Solid Phase Microextraction (SPME) as a modern sample preparation method was discussed. Based on theoretical and practical aspects of the SPME method, a comparison of extraction efficiency of aromatic hydrocarbons (benzene, toluene, ethylbenzene, m,p-xylene (BTEX)) as testing substances was performed. The various SPME coated fibers: commercial (polydimethylsiloxane - PDMS, polyacrylate - PA) and home-made (etoxy-polydimethylsiloxane - PDES, polyurethaneacrylate, fused silica, and fused silica after etching of hydrogen fluoride acid) were compared in these experiments. The extraction efficiency was displayed as the extracted mass for BTEX after extracting of standard solution with various SPME fibers. The most efficient extraction (adsorption on the fiber surface) is for the etoxy-polydimethylsiloxane-coated fibers after drying at 200°C than for other tested fibers. In addition, the possibility of SPME use (with the new PDES fibers) in the food and natural products analysis (wine, candies, herbs) was discussed. Many advantages, as well as disadvantages of the SPME method are described in details.

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.
