Article about particulate matter pollution during New-year’s Eve in the next issue of Náttúrufræðingurinn

In the next volume of Náttúrufræðingurinn there will be an article by me, and co-authors Þorsteinn Jóhannsson, Sigurður B. Finnsson and Anna R. Böðvarsdóttir about PM10 pollution during New-year’s Eve celebrations in Reykjavík.


Abstract.
The airborne particulate matter pollution (PM10) around New-years Eve in Reykjavik, Iceland, reaches values that are many times greater (up to 2374 µg/m3, 30 min value) than the typical daily peak values (~100 µg/m3, 30 min value).
Strong winds (and precipitation) are efficient in reducing the peak concentration, and changes in the wind direction, even for relatively calm winds, can complicate the time series.
Although the  concentration reaches high values, these pollution events are of short duration.
