Swedish suggested EQSs for WFDRiver Basin Specific Pollutants
In Sweden the regional water authorities are responsible for selecting River Basin Specific Pollutants and for setting EQS for the relevant substances. A report from the Swedish Environmental Protection Agency with suggested EQS for some substances is meant as a support for them in that work. In this document, three tables are translated to English from that report.
The Swedish version of the report (from 2008):
Table 6. SuggestedEQSwater (Inland surface waters) and EQSother surface waters. If EQS wateris missing, separate EQSsediment or EQSbiota are published in table 7.

1 The EQS for metals concern the dissolved part.
2 The EQS for Zink is based on added risk: the value is the added amount beyond the background concentration.
3 The EQS for nonylphenoletoxylates is based on the sum of nonylphenolequivalents (NPTEQ).
Table 7. EQSsedimentand/orEQSbiotaare suggested as complementing EQS for the substances where EQSwater is not sufficiently low to protect sediment living organisms and/or human and/or predators from secondary poisoning.

Table 8. Indicative EQSsediment (EP-EQSsediment) are calculated from the EQSwater based on the distribution between water/sediment.

1 Neutral andalkalineenvironment and acid environment respectively.
2 The EQS for Zink is based on added risk: the value is the added amount beyond the background concentration
3 PNEC is set to 49 mg/kg dw and is based on laboratory studies. Therefore, there are no risk for sediment living organisms under the given EP-EQSsediment.
4 The EQS for nonylphenol etoxylates is based on the sum of nonylphenolequivalents (NPTEQ).
