First evaluation of microplastics in shellfish Venus verrucosa L. (Bivalvia: Veneridae) in the Adriatic sea
AI summary Read the abstract
Researchers conducted the first evaluation of microplastic contamination in the bivalve Venus verrucosa collected from three sites along the Croatian Adriatic coast, finding microplastics at all locations. The study provides baseline data for microplastic accumulation in a commercially harvested shellfish species from the Adriatic Sea.
Mikroplastika je kao novi zagađivač pronađena u svim morskim staništima. Glavni ekološki rizik koji predstavlja je njezina biodostupnost pogotovo u školjkašima koji su zbog sesilnog načina života i hranjenja filtracijom morske vode izloženi česticama mikroplastike iz vodenog stupca. U ovom radu je ispitivano zagađenje mikroplastikom kod populacija komercijalno važne vrste školjkaša Venus verrucosa s tri lokacije duž hrvatske obale Jadrana (Limski, Šibenski i Malostonski zaljev). Analiza uzoraka prikupljenih u 2018. godini je uključivala broj, oblik i veličinu čestica mikroplastike kod 36 jedinki. Ukupni broj mikroplastike (MP) je varirao ovisno o tipu mikroplastike od 0,02 MP/g do 1,96 MP/g. Veličinski raspon mikroplastike se kretao od 0,18 µm do 211 µm s najmanjom brojnošću u Šibenskom zaljevu. Zabilježeni najučestaliji oblici mikroplastike su bili filamenti i fragmenti. Najviše zastupljena boja mikroplastike bila je prozirna (86%), a najmanje ružičasta (0,67%). Istraživanje je uključilo i analizu podataka o izlovu vrste V. verrucosa za razdoblje od 2008. do 2019. godine gdje se pokazalo da se najviše izlovljava priručnim alatima u Istarskoj županiji te je jedna od tri najeksploatiranije vrste školjkaša iz divljih populacija u Republici Hrvatskoj.

Assessment of microplastic particles ingested by Mytilus galloprovincialis along the Adriatic coast
AI summary Read the abstract
Researchers sampled 176 Mytilus galloprovincialis mussels from six stations across the Adriatic Sea as part of the INTERREG IT-HR MARLESS project, digesting tissue with acid and extracting microplastics via saturated sodium chloride filtration. Microplastics were detected at all sampled locations, with shape, size, and color characterization revealing widespread contamination across the study region.
Evaluation of human exposure to microplastics and nanoplastics related to the consumption of the striped venus clam Chamelea gallina caught in the Central Adriatic Sea (PLASTICVONG project)
AI summary Read the abstract
Researchers quantified microplastic and nanoplastic contamination in striped venus clams from Italian coastal waters and estimated consumer exposure through shellfish consumption. Both microplastics and nanoplastics were found in clam tissues, with exposure levels dependent on harvesting location and consumption frequency.
