This study provides data on the spatial variability of VOCs, PAHs, and EOX
compounds present in the marine inter-tidal sediments at Santander Bay, Nor
th Spain. The studied area is an estuarine of hi,oh ecological value with a
relevant socio-economic influence over the region. A sampling strategy was
developed taking into consideration the characterisation of the Bay, resul

of the nature and extent of the present organic pollution in the sediments
, in order to determine influence of sources and its optimum management.
