Pesticides and biocides - Hexachlorobenzene (median values)
This API provides access to a geospatial data layer showing median concentration values of hexachlorobenzene, a persistent pesticide and biocide compound, in Greek marine or coastal waters. It is published by the Hellenic Centre for Marine Research (HCMR) and served via a WMS interface as part of the EMODnet shared data layers. The dataset supports environmental monitoring and assessment of chemical contamination levels, offering researchers and public authorities a standardized way to visualize and analyze pesticide residue data at a national scale within Greece.”}Pesticides and biocides - Hexachlorobenzene (median values)
