Two assessment criteria are used to assess the status of metal concentrations: the
BACs were developed within the Oslo and Paris Commission framework with scientific advice from the International Council for the Exploration of the Sea. Mean concentrations significantly below the BAC are said to be near background.
ECs are used in the absence of any satisfactory criteria for assessing the ecological significance of metal concentrations. ECs are the maximum acceptable concentrations in food for the protection of public health.
BACs and ECs are available for the following metals
BAC | EC | ||||
mussels | oysters | fish | fish and bivalves | crustaceans | |
Cadmium | 960 | 3000 | 26 | 1000 | 500 |
Copper | 6000 | 6000 | |||

Two assessment criteria are used to assess the status of PAH concentrations: the
The assessment criteria were developed within the Oslo and Paris Commission framework with scientific advice from the International Council for the Exploration of the Sea. Mean concentrations significantly below the BAC are said to be near background. Concentrations below the EAC should not cause any chronic effects on marine organisms.
BACs and EACs are available for the following PAHs

Two assessment criteria are used to assess the status of chlorobiphenyl concentrations: the
The assessment criteria were developed within the Oslo and Paris Commission framework with scientific advice from the International Council for the Exploration of the Sea. Mean concentrations significantly below the BAC are said to be near background. Concentrations below the EAC should not cause any chronic effects on marine organisms.

Two assessment criteria are used to assess the status of organo-bromine concentrations: the
BACs were developed within the Oslo and Paris Commission framework with scientific advice from the International Council for the Exploration of the Sea. Mean concentrations significantly below the BAC are said to be near background.
FEQGs were developed under the Canadian Environmental Protection Act, 1999. Concentrations below the FEQG should not cause any chronic effects on marine organisms.
The BACs and FEQGs are currently being used on a trial basis following deliberations at OSPAR MIME 2017 and 2018.
BACs and FEQGs are available for the following organo-bromines
BAC | FEQG | ||
