Polycyclic aromatic hydrocarbons (PAHs) are broad environmental contaminants which due to their lipophilic profi le tend to be absorbed on particles and fi nally accumulate in marine environments. Analysis of PAHs is conducted in various commodities, such as water, sediment and in organisms, with bivalves possessing a predominant role due to their cumulative for organic contaminants and PAHs profi le. Substantial research has been performed on the effects of PAHs pollution on the bioindicator itself, the marine bivalve, in matters of subcellular, cellular, tissue or organ alterations. Taking into account the persistence of these compounds, their ubiquity and the variety of health effects they may elicit to invertebrates, it is imperative to focus on biomarkers assessment after acute or subchronic exposure to PAHs. Nowadays, a tiered approach in Mussel Watch Programs is followed with chemical analysis of PAHs in mussel tissues being accompanied by detection of effects at subcellular, cellular, tissue, organ or organism level. This combined methodology serves on a number of levels-it measures with precision current PAHs pollution status and it links this pollution to possible health effects on bivalve populations This review aspires to consolidate knowledge on PAHs analysis and the biological effects that they elicit in bivalves. In this context, it is provided an overview on PAHs pollution as monitored with the use of bivalves. Specifi c focus is given on: (1) PAHs analytical methodologies and their performance (2) levels of marine PAHs as measured through bivalves within the last decade; current pollution status and (3) health effects of PAHs on bivalves as shown from fi eld studies and laboratory experiments.
