Given the necessity to use a deterministic approach to derive the water, marine and
sediment EQS, the SCHEER does not accept that the Chen et al (2019) reference is
sufficiently reliable to support these quality standards. Using the information in the
dossier, the SCHEER would propose alternative MAC-QSfw of 1.6 mg L-1 and an MACQSsw
of 0.16 mg L-1. Similarly, data from the same Chen et al (2019) study was used to
underpin the AA-QS which SCHEER also found unsatisfactory. Using the information in the
dossier, the SCHEER would propose instead the alternative AA-QSfw of 0.0025 mg L-1 (or
2.5 μg L-1) and AA-QSsw of 0.00025 mg L-1 (or 0.25 μg L-1). Given these new proposed
EQS we request that new benthic organism (sediment) QS by calculated by the
Commission.
The calculated QSbiota,hh,food is 19.6 μg kg-1. It is the opinion of the SCHEER that the
latter is most suitable for determining the QS for human health. Therefore, the SCHEER
suggests a QSwater,hh, food of 7.0 μg L-1. The SCHEER proposes a QSdw, hh=0.54 μg L-1.
This value is below the AA-QSfw of 2.5 μg L-1, and so this would necessarily become the
most sensitive/appropriate QS for freshwater.
