1. Input of selected human pharmaceutical metabolites into the Norwegian aquatic environment
Although we did not detect any ATV metabolites in surface water, interestingly we did detect the presence of the main and active metabolite of the statin prodrug simvastatin (SV); simvastatin hydroxy carboxylic acid (SVA) in four of the surface water and sediments collected from Oslofjord.The surface water samples collected contained SVA at concentrations > LODand up to 66 ng L-1, whilst two sediment samples contained low ng g-1 (dw) concentrations of SVA also. No efﬂuent concentrations of SVA were determined; however, we have previously reported the occurrence of SV at low ng L-1 in VEAS WwTW efﬂuent suggesting from these preliminary data that efﬂuent concentrations of SVA would indeed be higher.
