    Återanvändning av textil via utvalda online marknadsplatser och appar: Undersökning avseende åren 2016 och 20172019Report (Other academic)
    Abstract [sv]

    SMED har på uppdrag av Naturvårdsverket undersökt mängden textilier som förmedlades för återanvändning via online marknadsplatser och appar från utvalda företag. Undersökningen omfattar uppgifter från sex företag som tydligt är aktiva på den svenska marknaden. Ingen uppräkning har gjorts för företag som valt att inte lämna uppgifter (bortfall). Den totala mängden textilier som förmedlas mellan konsumenter i Sverige via online marknadsplatser och appar bedöms därför vara större.

    De sex företag som ingick i undersökningen förmedlade totalt 970 ton kläder och hemtextil för återanvändning år 2016. Motsvarande siffra för 2017 är 1 300 ton, vilket motsvarar en ökning med 32 procent. År 2017 dominerades de förmedlade textilierna av damkläder (46 procent), följt av barnkläder (31 procent) och herrkläder (15 procent). Endast mindre mängder hemtextil förmedlades.

    Den totala mängden textil som 2017 förmedlades för återanvändning via de sex företagen i undersökningen motsvarade 0,13 kilogram per person i Sverige. Det motsvarar runt en procent av nettoimporten av nya textilier till den svenska marknaden. År 2016 motsvarade den totala mängden textil som förmedlas för återanvändning via de sex företagen i undersökningen bara runt tre procent av den totala mängden begagnade textilier som återanvändes via välgörenhetsorganisationer men 12 procent av mängden begagnade textilier som återanvändes i Sverige via välgörenhetsorganisationer.

    POPs, PFAS and metals in ringed seals (Pusa hispida botnica) from the Baltic 1978-20152019Report (Other academic)
    Abstract [en]

    Twenty two pooled samples from 69 juvenile ringed seals collected between 1974 and 2015 were analyzed for PCB (22 congeners), pesticides, PFAS, metals and selenium. Most seals were bycaught in fishing gear.

     

    All CB congeners were above the detection limits. CB-138 and -153 accounted for ca 50% of ∑PCB. CB-180 and -101 stood for ca 10 % each. ∑PCB decreased over the study period with approximately -4.6% annually and since 2000 the mean concentrations (i.e. in pooled samples) were below 9 mg/kg in these juvenile seals, which is the lowest suggested threshold for onset of physiological effects in experimental marine mammal studies.

    sDDT decreased with a rate of ca -8.9% yearly. The proportion of p,p’DDE increased over time as p,p’DDT decreased. Chlordanes and nonachlor also decreased over time (-4.6%). Trans-nonachlor was the most predominating compound. Finally, mirex decreased over time at a rate of approximately -2.3% annually.

     

    Nine PBDE congeners were analyzed in blubber. The predominating BDE was BDE-47 (ca 70%) followed by BDE-99 and BDE-100. Most BDE congeners peaked during the 1990s.

     

    Eleven perfluorinated substances were analysed. PFHxA and PFHpA were below detection limits in all but three samples not included in the statistical analyses. All but FOSA showed increasing trends over the study period, with increasing rates of +5-9% annually. However, if only looking at the last 15 years the concentrations appear stable (i.e. not increasing or decreasing). FOSA showed decreasing rates over the full period as well as the last 15 years. PFOS was observed in the highest concentrations (range 9.4-400 ng/g ww) and was the predominant PFAS. PFNA was the predominant PFCA followed by PFDA and PFUnDA.

     

    Arsenic (As), cadmium (Cd), cobalt (Co), copper (Cu), (Cr), mercury (Hg), manganese (Mn), nickel (Ni), selenium (Se) and zinc (Zn) were analysed in seal liver. Cr was below detection limit in all samples but one, which was at detection limit. Ni was below detection limit in all samples. Only Co showed slight decreasing concentrations, the concentrations of the other metals were stable over time. However, concentrations of Pb were very low, and after 2000 below detection limit (<0.03 mg/kg ww), indicating decreasing concentrations. The relationship Hg vs Se on a molar basis showed no trend over time. Generally, the ratio was slightly below 1, but in five samples it did exceeded 1 (mean ratio was 0.9).

    Det svenska nationella miljöövervakningsprogrammet för miljögifter i marin biota (fram till 2017 års data) - Temporal- och spatial variation2018Report (Other academic)
    Abstract [en]

    The report summarises the monitoring activities within the National Swedish Contaminant Programme in marine biota. In this report, we present time series and maps of most contaminants in various species but we only comment results that shows large differences compared to the previous year. Results show that herring from Holmöarna had elevated concentrations during the last two years of the time series for approximately half of the analysed metals, most chlorinated pesticides, polychlorinated biphenyls (PCBs) and brominated flame retardants (BFRs). The last two years’ Herring is on average one year older than the previous years’, heavier and the last years’ fat percentage is ca. 2 % higher compared to the year before. These differences in biological variables may have had an influence on the elevated contaminant concentrations. Also, herring from Väderöarna shows increasing concentrations for several chlorinated pesticides, PCBs, dioxins, and BFRs during the ten most recent years. A reason for this might be that the included fish were older during the seven most recent years, although their size was similar or smaller than previous years. Additionally, the fat percentage of the tissue has also decreased over time and might influence the results.

    This year’s report is also the first to show PFAS concentrations in Cod, Perch and Eelpout where Perch has the highest concentrations of most PFASs within the Baltic Proper sampling sites.

    This report is also the first report within the Swedish National Monitoring Programme of Contaminants in marine biota presenting environmental contaminant data in eggs of Common tern and Eurasian oystercatcher. In general, many of the compounds could be detected in Common tern and Eurasian oystercatcher.

    Concentrations of several of the contaminants are similar in the two species, but there are exceptions among each contaminant class and even opposing time trends for some contaminants. There are clear differences in contaminant concentrations between species for PCDD/Fs and BFRs; for most PCDD/Fs, concentrations are higher in Eurasian oystercatcher compared to Common tern, while for the BFRs concentrations are higher in Common tern, with the exception of HBCDD.

    Sammanfattning av aktiviteter utförda inom det Biogeografiska uppföljningssystemet för vedlevande evertebrater 2012-2018 och framtida planer inom systemet.2019Report (Other academic)
    Abstract [en]

    This report summaries the monitoring during 2012-2018 of 14 wood living invertebrates listed in the EU Habitats Directive (12 coleptera, Osmoderma eremita and one Pseudoscorpiones). The status of species and habitats in the directive should be reported to EU every six years. Next reporting will be in 2019.

    The monitoring is part of the so called “biogeographic monitoring system” and aims, among other things, to generate the information needed to make these reports. It was started in 2010 with the development of monitoring plans for the included species. During the years 2012 to 2018, methods have been tested and monitoring of the species' populations and habitats have been carried out.

    Eleven of the fourteen species are covered by so-called action plans for threatened species. Inventory and monitoring play a significant role in the action plans for the species, which is why large benefits can be obtained by coordination between the programs for the action plans and the biogeographic monitoring for these species.
