Heavy metals - Lead (median values)
This API, published by the Hellenic Centre for Marine Research (HCMR), provides a web map service (WMS) layer showing median concentration values of lead, a heavy metal, in the marine environment around Greece. It is part of the EMODnet shared data layers infrastructure and offers geospatial access to monitoring or modelled data on marine contamination. The service is freely accessible without authentication and is intended for use in environmental assessment, marine pollution monitoring, and research on heavy metal distribution in coastal and offshore waters at the national level.Heavy metals - Lead (median values)
