Lots of Particulate Matter in the east on 2010-06-30

Considerable PM10 was in the east (the ash fallout zone) yesterday, 30 June 2010. At Hvolsvöllur the 24-hour mean was ~340 micro-g/m3, at Vik it was 169 and Heimaland 152 (always micro-g/m3).

Some of this seems to have blown in over the Reykajvik area. Stations around the greater Reykajvik area measured increased levels of PM10 from about 16:00.

Even better air quality in the ash zone, except at Vik on 2010-06-29

Very low levels of PM₁₀ at Heimaland and Hvolsvöllur on 29 June 2010. Still a little high at Vik (70 micro-g/m³; health limit 50 micro-g/m³).

Much better air quality in the ash fallout zone on 2010-06-28

The 24-hour average was just over the health limit at Vík, but just below at Hvolsvöllur and Heimaland.

There is a peak in the concentration at Vík just after midnight, and then lower levels. Small peak around 4 at Hvolsvöllur.

Advise for wildfires and PM10 pollution

Couple of web-pages, unfortunately only in Icelandic so far, about the health risks associated with different levels of PM10 pollution, and how to not start wildfires by accidents :-)

Still quite a bit of particulate matter, especially at Heimaland (246 micro-g/m3) and Hvolsvöllur (152 micro-g/m3), but also at Vík (100 micro-g/m3).
