Sažetak
Airborne particulate matter (PM) is a complex mixture of solid or liquid particles dispersed and transported in atmosphere. The current interest in PM is mainly due to its adverse effect on human health, influence on the environment and its potential role in climate change. PM originates from a variety of natural or anthropogenic sources which affects its composition and chemical properties. Within the project “Biochemical responses of oligotrophic Adriatic surface ecosystems to atmospheric deposition inputs” (BiREADI IP-2018-01-3105), funded by the Croatian Science Foundation, influence of metals originating from the atmosphere and their impact on sea surface ecosystems was investigated. This paper presents the results of analyses of metals in PM10 particle fraction collected during six-months field campaign, from February to July 2019. Samples were collected continuously at a background coastal station of the Division for Marine and Environmental Research, Ruđer Bošković Institute, in the vicinity of the city of Šibenik. PM10 particles were microwave digested with nitric acid and 22 metals were analysed by inductively coupled plasma mass spectrometry (ICPMS). Obtained results were characteristic for sea aerosol but also showed the influence of anthropogenic sources as well as significant input of metals through dust intrusion episode from Sahara and through several open wild fires recorded near the sampling area.
