Biomarker responses in the clam Ruditapes philippinarum and contamination levels in sediments from seaward and landward sites in the Lagoon of Venice

- Clams were monthly collected in both a seaward site and a landward site.
- Various biomarkers were measured at cellular, tissue and organism level.
- Concentrations of persistent organic pollutants were measured in surface sediments.
- Contamination levels of sediments were similar between the two sampling sites.
- Influence of abiotic factors cannot be excluded in influencing biomarkers.
