International Pilot Study for the determination of Riverine Inputs of Polycyclic Aromatic Hydrocarbons (PAHs) to the Maritime Area on the basis of a harmonised methodology

The objectives of this study are the determination of an annual load of the polycyclic aromatic hydrocarbons (PAHs) for the seven selected rivers and the development of a harmonised methodology for the estimation of these riverine loads into the North Sea and the North-east Atlantic. For this purpose Belgium, Denmark, Germany (lead country), the Netherlands, and Spain contributed to this study with measuring programmes on seven rivers. Detailed results of each participating country are described in the Individual Parts in Annexes 2 to 6.
