Waterbase - TCM: QualityBiota
The QualityBiota table contains aggregated data on hazardous substances in biota, measured at Eionet-Water transitional, coastal or marine water monitoring stations, provided by national sources or Marine Conventions. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Quality data with their respective Stations and Pressures data.
