Sažetak
Anthropogenic climate change is altering ecological and human systems globally, including national parks that conserve unique but vulnerable ecosystems and biodiversity. Yet the magnitude and spatial patterns of climate change across national parks are generally unknown. The National Park (NP) Brijuni in Croatia encompasses 14 islands and islets covering an area of 33.9 km2 in the northern Adriatic Sea, representing a unique microenvironment with a specific biodiversity, natural, cultural and historical features. Due to its location, NP Brijuni is in direct threat of potentially strong air pollution from regional and long-range sources from continental Europe. However, the atmospheric pollution impacts to the area of the NP Brijuni have been unknown. This work presents the first insight into the air pollution sources, its seasonal variabilities as well as atmospheric deposition impacts to the area of NP Brijuni. The sampling campaign at NP Brijuni was conducted from June to November 2020 and included on-line measurements of black carbon (BC) concentrations and collection of particulate matter (PM10), wet and total deposition samples. The results of BC concentrations and its source apportionment and dataset comprising dominant ions (NO3-, SO42-, Cl-, Na+, K+, Ca2+, Mg2+, NH4+) and organic matter (organic carbon and water soluble organic carbon) in PM10 and deposition samples were statistically analysed and discussed considering different seasons, meteorological conditions and specific air-mass inputs in order to better understand the extent of the changing environment as a main prerequisites for air quality management, planning and implementation of appropriate environmental protection measures in the NP Brijuni. Acknowledgment: This work has been supported by National Park Brijuni under the „Insight into the variability and composition of atmospheric deposition in the area of Brijuni National Park“ project, and by and Croatian Science Foundation under the IP-2018-01-3105 BiREADI project.
