Sažetak
In our society plastic is one of the go to materials and it has a major commercial, industrial, medicinal and municipal applications. Plastic production has increased dramatically from the 1950s, and following this plastic waste has accumulated in the environment at an increasing rate. There it is subjected to wind and river-driven transport, ultimately reaching the marine environment. Data on amounts of plastic litter in the Mediterranean is generally limited and shows great variations. All sources report high amounts of plastics, in both floating and beach litter, as well as in litter on the sea floor. Major concerns have been raised about microplastics and its impact on marine organisms. Due to its small size, microplastics may be ingested by the fauna, with uncertain consequences for the health of the organism. The objectives of this study were to (i) assess the presence of plastics in marine litter, (ii) identify presence of microplastics in the water column (iii) examine the bioaccumulation of microplastics, via a proxy - common pandora (Pagellus erythrinus), a popular food fish in Mediterranean countries. A frequented beach was surveyed in April, June and November 2014, following the methodology suggested through the Marine Framework Directive. Marine litter was classified into 8 main categories: plastic, rubber, cloth, paper, wood, metal, glass and other. Major contribution was from cigarette buds and filters, plastic pieces 2.5 cm > < 50cm, polystyrene pieces 0 - 2.5 cm and other plastic/polystyrene items. The presence of microplastics in the water column was investigated on a transect across the northern Adriatic. Ingestion of microplastics was investigated on common pandora by stomach con-tent analysis. This is the first investigation of this kind in the north-eastern Adriatic Sea, and the collected data justify a growing concern about microplastics and its impact on the marine environment.
