of countries do not have required standards for sediment pollution estimate. In
such cases, the government authorities use often the recommended values
based on reference concentrations. However, some ICES members (Norway,
Sweden and the Netherlands) regulated the sediment classification, which
may be based on concentration of single contaminant (Table 3).
Country Legislation Notes
Belgium x Data compared against OSPAR BC
Denmark x Locally derived BCs from reference sediment (mainly for metals)
Finland x
France x Data compared against OSPAR BRC and locally derived BCs
Irland x
Canada ? ISQG and PEL approach from field data demonstrating
associations between chemistry and biological effects.
Netherlands yes Two-class system (NEC and MPC) based on equilibrium
partitioning or ecotoxicological data.
Norway yes Five class system. Data compared against local, surface
sediment concentrations.
Germany x
Portugal x Data compared against OSPAR BC.
Spain x Data compared with international (e.g. USEPA) and locally
derived BCs
Sweden yes Five-class system.. BCs derived from cored sediments
UK
(England
and Wales)
x Data compared against OSPAR BRC: locally derived BCs in
preparation

Norwegian and Swedish standards predict five-class sediment classification.
Sediment classification standards in Norway are given in the Table 4.
Contaminant Unit Class 1 Class 2 Class 3 Class 4 Class 5
(good) (moderate) (poor) (bad)
(very bad)
Cooper mg/kg < 35 35 - 150 150 - 700 700 - 1500 > 1500
Zinc mg/kg < 150 150 - 650 650 - 3000 3000- 10000 > 10000
Cadmium mg/kg 10
Chromium mg/kg < 70 70 - 300 300 - 1500 1500 - 5000 > 5000
Nickel mg/kg 1500
Lead mg/kg 1500
Mercury mg/kg 5
Total PAH µg/kg 20000
PCB µg/kg < 5 5-25 25-100 100-300 >300

dry weight
By comparing the defined maximum values of single contaminant in sediment
to be dredged at the Port of Ploce with limit values in Norwegian standards
the implication is as follows:
- cooper, chromium, PAH and PCB meet limit values for the 1 st class
