SARF0011: Review of Environmental Quality Standards (EQSs) for use in assimilative capacity model development

Objectives

1. Develop a conceptual model for finfish aquaculture in Scotland, drawing upon all existing white and grey literature, discussion with regulators and aquaculture facility operators and guidance provided by Power et al. [1]. Use the conceptual model to identify substances that may be discharged from finfish aquaculture, their pathways through the environment and the biological receptors that may be exposed to them (Lead Researcher: Beth Power; Months 1-3.)

2. Review the availability of short-term and long-term EQS for all substances identified in 1. above and critically review the data upon which they are based for their relevance to important conservation features and sub-features. Compare current UK EQS with EQS likely to be developed for the same substances under the WFD (including EQS based on secondary poisoning) (Lead Researcher: Mark Crane.)

3. Fill any gaps for short-term or long-term EQS using either toxicity data or Quantitative Structure Activity Relationships (Lead Researcher: Ian Johnson.)

4. Liaise regularly with the Project Leader for the associated modelling project to ensure that EQS are fit for purpose within assimilative capacity models, and produce a Quality Assured final report (Lead Researcher: Ian Codling.)

Summary

The main aim of this project is to review exisiting EQS for their suitability for use in assimilative capacity models. This is to ensure that these EQS help maintain the integrity and Favourable Conservation Status of habitats and species in marine Special Areas of Conservation. The project is relevant to SARF because EQS will be adopted for a suite of environmental variables relevant to water quality regulation for aquaculture. These EQS will be amongst the input parameters for assimilative capacity models developed in an associated SARF research project. The project results will assist competent authorities when performing Appropriate Assessments of the risk of cumulative impacts on site integrity. This project brings together a consortium of researchers, with expertise in managing water quality impacts at marine sites, derivation of EQS and Ecological Risk Assessment (ERA)
