Abstract [sv]

Målet med projektet var att identifiera akvatiska punktkällor för flamskyddsmedel (FRs) till den svenska miljön. Detta gjordes genom att mäta halter i olika typer av vattenflöden och beräkna dagliga flöden av FRs med hjälp av vattenmassaflöden. De verksamheter som undersöktes inkluderade avloppsreningsverk (n = 5), avfallsanläggningar (n = 4), flygplatser (n = 5), industrier (n = 2), dagvatten från stads/industriområden (n = 6) samt lantbruk (n = 2). Vatten- (n = 42) och partikelprover (n = 42) samlades in under februari-april 2018 och analyserades för totalt 62 olika FRs från tre olika ämnesklasser: halogenerade FRs (HFRs), organofosfater (OPFRs) och polybromerade difenyletrar (PBDEs).

Totalt detekterades 34 olika FRs i minst ett prov. Flest antal olika FRs hittades i provet från en avfallsanläggning (Högbytorp; n = 23), följt av Skavsta flygplats (n = 17), Ärna flygplats (n = 16) och Ryaverket avloppsreningsverk (n = 16). I genomsnitt hittades flest flamskyddsmedel vid avfallsanläggningar (n = 15 ± 5), följt av avloppsreningsverk (n = 13 ± 3), dagvatten (n = 11 ± 2), flygplatser (n = 9 ± 6) och industri (n = 5 ± 1). TDCIPP var det FR som detekterades i flest antal prover (78 % av alla prover), följt av BDE66 (68 %), TEHP (57 %), TCIPP (57 %) och TBOEP (57 %).

Den totala halten FRs i proverna varierade mellan <MQL och 130 000 ng L-1. Den högsta totala koncentrationen hittades i proverna från Skavsta (130 000 ng L-1), Vivsta (11 000 ng L-1), Högbytorp (6 900 ng L-1) och Henriksdal (4 300-6 600 ng L-1). Generellt bidrog OPFRs mest till de totala koncentrationerna med i genomsnitt 76 %, jämfört med halogenerade FRs (7 %) och PBDEs (6 %).

De beräknade flödena av FRs varierade mellan <MQL och 1.8 kg dag-1. Fyra provtagningsplatser hade betydligt högre flöden än övriga platser. Tre av dessa fyra var avloppsreningsverk (Henriksdal: 1.2 - 1.8 kg dag-1; Ryaverket: 0.67 kg dag-1; Skebäcksverket: 0.18 kg dag-1), vilket tyder på att avloppsreningsverk kan vara viktiga spridningsvägar av FRs till den svenska vattenmiljön. Med tanke på studiens screeningkaraktär så bör samtliga rapporterade koncentrationer och flöden tolkas med försiktighet.

Abstract [en]

The aim of this study was to identify aquatic point sources of flame retardants (FRs) to the Swedish environment. This was done by measuring FR levels in different types of water flows and by estimating daily fluxes of FRs using water flow data. The sampled sites included wastewater treatment plants (WWTPs, n = 5), waste treatment facilities (WTFs, n = 4), airports (n = 5), industries (n = 2), storm water from urban/industrial areas (n = 6), and agriculture (n = 2). Water (n = 42) and particulate (n = 42) samples were collected during February-April 2018 and analyzed for in total 62 target FRs from three different classes: halogenated FRs (HFRs), organophosphorus FRs (OPFRs) and polybrominated diphenyl ethers (PBDEs).

In total, 34 different FRs were detected in at least one sample. The highest number of FRs were detected in a sample from a WTF (Högbytorp, n = 23), followed by Skavsta airport (n = 17), Ärna airport (n = 16), and Ryaverket WWTP (n = 16). The highest average number of detected FRs (± standard deviation) were found for WTFs (n = 15 ± 5), followed by WWTPs (n = 13 ± 3), storm water (n = 11 ± 2), airport (n = 9 ± 6), and industry (n = 5 ± 1). The most frequently detected FR was TDCIPP (78% of all samples), followed by BDE66 (68%), TEHP (57%), TCIPP (57%), and TBOEP (57%).

Total bulk FR concentrations ranged between <MQL to 130 000 ng L-1. The highest total bulk concentrations were found in the samples from Skavsta airport (130 000 ng L-1), Vivsta …. (11 000 ng L-1), Högbytorp WTF (6 900 ng L-1) and Henriksdal WWTP (4 300-6 600ng L-1). In general, OPFRs contributed the most to the total concentrations with on average 76% of the total bulk concentration followed by HFRs (7%), and PBDEs (6%).

FR fluxes ranged between <MQL and 1.8 kg day-1. Four sites showed considerably higher total fluxes than the other sites. Out of those, three sites were WWTPs (Henriksdal: 1.2-1.8 kg day-1; Ryaverket: 0.67 kg day-1; Skebäcksverket: 0.18 kg day-1), indicating WWTPs as important pathways of FRs to the Swedish environment. Considering the screening design of this study, all reported concentrations and fluxes should be interpreted with care.
