Since 2001, the Oceanographic Centre of Murcia (Spanish Institute of Oceanography, IEO) started to include selected biomarkers within the chemical pollution monitoring activities conducted along the Iberian Mediterranean coast. The main objectives of this biomonitoring programme are: (1) the determination of spatial distribution and temporal trends of chemical pollution in coastal and reference areas; (2) to seek evidence of detrimental biological effects and assess them over time. Sediment samples, feral fish (Mullus barbatus) and wild mussels (Mytilus galloprovincialis) are analysed yearly for selected pollutants (trace metals, organochlorinated compounds and polycyclic aromatic hydrocarbons) and selected biomarkers are measured in fish and/or mussels (EROD activity, metallothionein content, micronuclei frequency, genotoxic damages, acetylcholinesterase, stress on stress and lysosomal membrane stability). An integrated chemical-biological effect assessment approach is being conducted ...
