37 Procent av totalamängden partiklar [%] Procent av totalmängden partiklar enligt SS-EN 481 standarden alveolisk torakal inhalerbar Aerodynamisk partikeldiameter [mm] Grimm Seminar 46

38 Förklaringar Inhalerbar fraktion: Den mängd partiklar, av totalmängden partiklar i luften, som inandas genom näsa och mun. Torakal fraktion: Den del av de inhalerbara partiklarna som passerar struphuvudet. Respirabel fraktion: Den del av de inhalerbara partiklarna som når längst ner i luftvägarna till alveolerna i lungorna Grimm Seminar 47

39 Definitioner, AFS 2011:18 ( ) Benämnning Luftförorening Hygieniskt gränsvärde Förklaring Ämne eller blandning av ämnen i luft som över en viss halt kan medföra ohälsa Högsta godtagbara genomsnittshalt av en luftförorening i inandningsluften beräknat som ett tidsvägt medelvärde. Ett hygieniskt gränsvärde är antingen ett nivågränsvärde eller ett takgränsvärde. Nivågränsvärde Hygieniskt gränsvärde för exponering under en arbetsdag, normalt 8 timmar. Takgränsvärde Hygieniskt gränsvärde för exponering under en referensperiod av 15 minuter. För ammoniak, monoisocyanater och diisocyanater gäller referensperioden 5 minuter. Korttidsvärde Ett rekommenderat högsta värde för exponering beräknat som ett tidsvägt medelvärde under en referensperiod av 15 minuter. Korttidsvärden är rekommenderade värden som tjänar som riktlinjer i skyddsarbetet och används vid bedömning av exponeringsförhållanden Grimm Seminar 48

40 Gränsvärdeslistan, AFS 2011:18 Typ av Luftförorening Enhet Gaser, ångor mg/m 3 ; ppm (ml/m 3, cm 3 /m 3 ) Damm, rök, dimma, aerosol mg/m 3 Enzymer glycinenheter/m 3 Fibrer fibrer/cm 3 Radon Bq/m Grimm Seminar 49

41 Gränsvärden, några exempel AFS 2011:18 Ämne Damm, organiskt - inhalerbart damm - respirabelt damm År Nivågränsvärde (mg/m 3 ) Damm och dimma, organiskt -totaldamm Damm, bomull (råbomull) - totaldamm ,5 Damm, grafit -totaldamm Damm, härdplast - totaldamm Damm, kol inkl. kimrök - totaldamm Damm, mjöl - inhalerbart damm Grimm Seminar

42 Rökpartiklar, exv. svetsning Rökpartiklar, från till exempel svetsning, är i regel av storleksordningen < 1 μm, vilket innebär att dessa till största delen består av respirabla partiklar. Det innebär att alla rökpartiklar kan betraktas som respirabla. Därför behöver man inte använda provtagare med föravskiljare vid provtagning då enbart rök föreligger Grimm Seminar 51

43 Metallrök vid exv. svetsning Metallrök bildas i regel genom kondensation och eventuell oxidation av metallånga. Vanligtvis utför svetsaren även slipning eller slaggning varför även det luftburna dammet i en svetsares andningszon kan bestå av en hög andel ickerespirabelt damm Grimm Seminar 52
