Fish plasma concentrations (FPC) were predicted by the Fish
Plasma Model described by Valenti et al. (2012), using the following
equations:
log PBlood:Water ¼ 0:73 log D7:5 0:88 ð1Þ
FPC ¼ ½Water concentration;lg L1 PBlood:water ð2Þ
In the original model, Eq. (1) includes the log KOW instead of the
log D7.5. However, prior research has shown that water pH affects
the ionization, bioavailability, and toxicity of SSRIs (Valenti et al.,
2012). Therefore, logD (3.32 at pH 7.5) was calculated following
the method developed by Scherrer and Howard (1977) and substituted
for the log KOW value in Eq. (1).
