The file sediment_regional_assessment_metals.html contains regional assessments of metal concentrations in sediment from the 2020 assessment of the UK's Clean Seas Environment Monitoring Programme (CSEMP). The data underpinning this assessment can be found in the files sediment_data.csv and sediment_regional_data.csv.

This is one of a series of regional assessments of contaminants in sediment. The series consists of regional assessments for metals, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). These are described in the resources:
