Evaluation of bulk deposition in protected woodland area in western Poland.
Research on precipitation carried out systematically at the University station at Jeziory in the Wielkopolski National Park (western Poland) allowed the determination of pollutants deposited with precipitation in this forest ecosystem. During 13 years of study, the pH of precipitation was found to persist at a low level (4.33 on average), which resulted a substantial deposition of H(+). Values of acidifying and basic ions deposited in this area were determined and compared with the respective figures obtained at selected EMEP stations studying background pollution, the means for Poland, and areas subjected to considerable human impact. The use of the critical load function made it possible to establish that the S and N deposition for 2002-2005 were below its line.
