Scope

Persistent pollutant concentrations in fish feed describes the relative level of pollutants (compared with the business as usual) that can be achieved via changing the raw material and processes of producing fish feed.

Definition

Data

Pollutant concentrations in fish feed can be further reduced from current levels. The estimate of 0-100 % with a gradual decrease in probability density is based on author judgement. It reflects rather a theoretical range of improvement than a realistic estimate.
