The wind rose analysis has been performed for the town of Radom in Central Poland. It was found that West and South-West wind directions significantly dominate in the wind rose, causing PAHs influx from coal power stations. The analysis of the PAHs accumulation in water, soil and bottom sediments based on the fugacity and partition coefficients model has been performed for Domaniów Lake. The results have been compared with the experimental PAHs concentrations in the lake, in- and out-flowing waters as well as in the dust over the lake.

The titration Omega MicroCal microcalorimeter (ITC) was used to obtain the enthalpy changes accompanying dilution of buffer solutions of lysozyme. Titration calorimetry affords a convenient method for the estimation of enthalpic pairwise solute-solute interaction parameters (hxx}- In this paper the results of determination of the enthalpy of dilution and then evaluated pair interaction coefficients (hxx) of lysozyme in a buffer containing 0.1 M sodium acetate, pH 4.25 at temperatures 288.15, 298.15, and 308.15 K are presented.
