Znaczenie konkurencji i konkurencyjności wzrasta wraz z pogłębianiem się procesów internacjonalizacji i globalizacji na świecie. Globalizacja procesów gospodarczych spowodowała znaczną swobodę w przemieszczaniu się kapitału, który szuka najkorzystniejszej lokalizacji, stwarzającej najlepsze możliwości dla długofalowego rozwoju danego przedsięwzięcia. Wskazano na zróżnicowanie regionalne konkurencyjnych obszarów wiejskich w Polsce oraz usytuowanie rolnictwa w warunkach globalizacji procesów gospodarczych.

The importance of competition and competitiveness increases with expansion of internationalization and globalization processes worldwide. Globalization of economic processes resulted in a significant level offreedom in movement of capital that is searching for the best location offering the best opportunities for long-term development of a given project. This paper points at regional differences of competing rural areas in Poland and positioning of agriculture in the environment of economic processes globalization.

A remotely operated model ship has been constructed to provide a mobile platform for measurements in the coastal waters. on board both dissolved oxygen and water temperature microcomputer probes as well as data loggers along with a water pump were deployed. This set-up allowed us to cross the coastal breaking wave zone and trace both oxygen and water temperature with a frequency of 1-15 seconds, as well as to collect samples of subsurface water. The constructed model was successfully used under conditions of high wind speed and during the winter, when measurements in coastal waters are most difficult and dangerous. Data on dissolved oxygen distribution showed enhanced oxygen evasion taking place within the breaking wave paths along the coastal barriers. Results indicate that breaking waves control the dissolved oxygen and other gaseous content in the coastal surface waters as well as their water-to-air fluxes.

Measurements of total gaseous mercury (TGM) were carried out in the Polish coastal zone of the Gulf of Gdańsk from Hel, situated at the end the tip of the Hel Peninsula, to Piaski in the Vistula Pit. The results were recorded in the atmosphere 150 cm above the ground using an automatic analyzer Gardis 1A in March, April and May 1999. The mercury concentration over the coastal zone of the Gulf of Gdańsk did not exceed maximum permissible levels and were at levels similar to those in other maritime regions of the Baltic Sea and the North Sea. The average concentration of mercury was 3.4 ng m-3. Increased TGM concentrations of approximately 8.2 ng m-3 occurred locally near the sewage treatment facility in Sztutowo, on the tip of the Hel Peninsula and in the Tri-Cities near the industrial areas of shipyards and the harbor. No increased concentrations of gaseous mercury were registered in the vicinity of the heat and power plant or the refinery as chimneys release fumes at high altitudes. What is more, the mercury concentrations recorded in the forests of the Vistula Lagoon and the Hel Pit were nine times lower than the average concentration. Laboratory experiments carried out on samples of sea water from three coastal measurement stations proved that mixing in the sea surf zone influences the emission of mercury from the water into the atmosphere. The emission of gaseous mercury from the surface waters of the Gulf of Gdańsk was higher in March when the life processes in the water were still slow and bioaccumulation was very limited.

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
