Abstract [sv]

Projektets huvudsakliga mål var att studera förekomsten av utvalda ämnen från vattenförvaltningens bevakningslista (amoxicillin, ciprofloxacin, sulfametoxazol, trimetoprim, venlafaxin, desvenlafaxin, azitromycin, klaritromycin, flukonazol, klotrimazol, imazalil, ipkonazol, metkonazol, mikonazol, prokloraz, tebukonazol och tetrakonazol) i sju svenska avrinningsområden påverkade av avloppsreningsverk. Andra organiska miljöföroreningar var också inkluderade, så som läkemedel, personvårdsprodukter, industrikemikalier och PFAS, på grund av deras potentiellt allvarliga effekter vid låga doser i miljön.

De studerade svenska avrinningsområdena visade på en variation av organiska miljöföroreningar på grund av hydrologi och antropogen påverkan (jordbruk, urban, och industriell). Totalt 70 organiska miljöföroreningar detekterades i minst ett prov, med medelkoncentrationer som varierade från ng/L till mg/L i prover från avloppsvatten och från ng/L till μg/L i ytvattenprover. De dominerande substanserna var tramadol, lidokain, metoprolol och koffein på alla provplatser. Koncentrationer uppströms i recipienten var i medel en tiondel av koncentrationerna nedströms i recipienten respektive utgående avloppsvatten. Det visades att höga koncentrationer av organiska miljöföroreningar från avloppsreningsverken introducerades in i den akvatiska miljön.

Ett antal ämnen från vattenförvaltningens bevakningslistadetekterades, bland annat sulfametoxazol, erytromycin, och azitromycin, flukonazol och venlafaxin samt dess metabolit desvenlafaxin. Fler studier behövs för den säsongs- och platsmässiga variationen av organiska miljöföroreningar i den akvatiska miljön.

Abstract [en]

The main aim of the project was to investigate the occurrence of selected EU Water Framework Watch List substances (amoxicillin, ciprofloxacin sulfamethoxazole, trimethoprim, venlafaxine, O-desmethylvenlafaxine, azithromycin, clarithromycin, fluconazole, clotrimazole, imazalil, ipconazole, metconazole, miconazole, procloraz, tebuconazole and tetraconazole) in seven Swedish river catchments impacted by WWTPs. Other OMPs were also included, such as pharmaceuticals, personal care products, industrial chemicals, PFASs, due to potential of their adverse effects at low doses to the environment.

The studied Swedish river catchments showed distribution of OMPs due to hydrology and anthropogenic pressures and impacts (agricultural, urban, and industrial). A total of 70 OMPs were detected in at least one sample, in mean concentrations ranging from ng/L to mg/L in wastewater samples and from ng/L to μg/L in surface water samples. Dominant compounds were tramadol, lidocaine, metoprolol and caffeine in all sampling sites. Upstream recipient samples showed on average ten times lower OMP concentrations compared to recipient samples downstream of the respective WWTP effluents. It was shown that the high concentrations of OMPs in WWTPs are introduced into aquatic environments. Therefore, the effect of treatment performance and process stability in WWTPs should be evaluated in reducing the concentrations of OMPs.

A number of Watch list compounds were detected including sulfamethoxazole, erythromycin and azithromycin, fluconazole and venlafaxine and its metabolite desvenlafaxine. More studies are needed in the seasonal and spatial distribution of OMPs in the aquatic environment.
