DOIAbstract
Bivalves are worldwide sentinels of anthropogenic pollution. The inclusion of biomarker responses in chemical monitoring is a recommended practise that has to overcome some difficulties. One of them is the time frame between sample collection and sample processing in order to ensure the preservation of enzymatic activities. In the presentstudy, threebivalve species ofcommercial interest (mussel, Mytilus galloprovincialis, razor shell, Solen marginatus, and cockle, Cerastoderma edule) were processed within<2h after being retrieved from their natural habitat, and 24h after being transported in air under cold conditions (6–8°C) to laboratory facilities. The enzymatic activities were compared in the three species submitted to both conditions reve...
