The paper presents the results of a study on the effects of meteorological conditions on the total hydrocarbon concentrations (THC) in the atmosphere where THC denotes the sum of methane and non-methane hydrocarbons. The testing area was contained within the limits of the Gdańsk Refinery located in the eastern part of Gdańsk in the coastal zone of the southern Baltic Sea (Fig. l).The experimen-tal data were collected by the Automatic Air Monitoring System of Gdańsk Refinery, and meteorological parameters were measured at Gdańsk-Świbno synoptic station in a period of 351 days. The data were evaluated with the aim of revealing spatial differen-tiation in THC concentrations in summer and winter (warm and cold seasons) and over the year, as well as to determine the frequency of the average daily concen-tration classes at particular measurement points under specific meteorological con-ditions. Meteorological situations influenc-ing THC concentrations were defined and statistical analysis yielded a quality class-ification of the atmosphere around the Gdańsk Refinery.
