8.1 Fine particulate matter (PM2.5) concentration (μg/m3)

8.1 Svifryksmengun (PM2.5)

Fine particulate matter (PM2.5) concentration shall be calculated as the total mass of collected particles that are 2,5 μm or less in diameter (numerator) divided by the volume of air sampled in standard cubic metres (μg/m3) (denominator). The result shall be expressed as the concentration of PM2.5 in micrograms per standard cubic metre (μg/m3). Data source: Environmental and Public Health Office of Hafnarfjörður, Garðabær and Kópavogur.

Styrkur fíns svifryks (PM2.5) skal reiknaður sem heildarmassi safnaðra agna sem eru 2,5 μm eða minna í þvermál (teljari) deilt með því magni lofts sem sýni er tekið í venjulegum rúmmetrum (μg/m3) (nefnari). Niðurstaðan skal sett fram sem styrkur PM2,5 í míkrógrömmum á rúmmetra (μg/m3). Gagnaveitur: Heilbrigðiseftirlit Hafnafjarðar, Garðabæjar og Kópavogs.
