The basic form of pollution is characterized by a microscopic size and solid state and it is called particulates or particulate matter. Unfortunately, these forms undergo a variety of transformations, which consequently can sometimes be easily modified and even cause an increase in their toxicity. This work was devoted to join the composition of various materials being residues after different combustion processes with the distribution of elements and molecules within studied surfaces. The content of chosen elements was determined using ICP-MS and ICP-OES methods. Elemental and/or molecular distribution was studied using surface sensitive techniques, SEM-EDS and ToF-SIMS. The obtained results revealed that the composition and morphology of particles are strongly influenced by the type of material and combustion conditions.
A one-year record of airborne microorganisms content in the region of the seaside resort in Sopot and in a few locations along the coastline of the Gulf of Gdansk are presented. The air samples were collected by means of filtration method using an apparatus produced by Sartorius. In addition, several investigations were performed to compare the results of three sampling methods: sedimentation method according to Polish Regulation [1], filtration, and impaction. The total number of mesophilic, psychrophilic bacteria and fungi concentrations in air were determined. Between January and December 1998 the number of mesophilic bacteria in air varied from a few to 308 CFU/m3 (CFU-Colony Forming Units), while the number of psychrophilic bacteria varied from 1 to 190 CFU/m3. The respective fungi content varied from 5 to 1100 CFU/m3. The monthly and seasonal geometrical mean values were calculated showing that the maximum seasonal occurrence of studied groups of microorganisms were observed at different times
