Marine Environmental Assessment Group data for organic contaminants, metals, biological effects and water chemistry collected for the Clean Seas Environment Monitoring Programme (CSEMP). Sediment and biota samples are analysed for organic contaminants (PAHs, PCBs and PBDEs) and trace metals. Biological effects are also measured in biota. Nutrients are measured in water samples. This layer shows the assessments from the UK Marine Environment Monitoring and Assessment National (MERMAN) database for reporting .comet assay in mussels, which shows cellular-level marker of exposure to genotoxic contaminants. Higher values equate to more damage / exposure to the contaminants.
All data is submitted to the UK Merman database.
