Svifryksmengun

Svifryk hefur heilsuspillandi įhrif, veldur sjónmengun og er, eins og önnur mengun, slęm fyrir umhverfiš. Almenn višmiš um loftgęši vegna svifryksmengunar og rįšleggingar um višbrögš viš svifryksmengun, meira .

Reiknilķkan

Unniš er aš gerš lķkans af styrk svifryksmengunar, meš ašstoš styrkja frį Vegageršinni og Orkuveitu Reykjavķkur.  Meira ...

Pollution in Bejing Umferš

Umferš er ein helsta uppspretta svifryks, bęši vegna śtblįsturs bifreiša og uppspęningar į malbiki.  Vešurfarsžęttir eins og vindhraši og śrkoma hafa einnig veruleg įhrif į styrk svifryksmengunar.

Unniš er aš lķkangerš sem tekur tillit til žessara žįtta ķ samvinnu viš Vegageršina og Reykjavķkurborg.

New year's fireworks in Iceland Įramót

Um hver įramót skjótum viš Ķslendingar upp ~600 tonnum af flugeldum.  Svifryksmengunin samhliša žessu er oft alveg ótrśleg - sem sést kannski best į žvķ aš skyggniš veršur stundum nįnast ekkert.  Ķ grein (Opnast ķ nżjum glugga / Opens in a new window) sem birtist ķ Nįttśrufręšingnum er fjallaš nįnar um svifryksmengun um įramót ķ Reykjavķk.

Sandstormar

Sandstormar verša žegar žurrt er ķ vešri, en sterkur vindur varir ķ nokkurn tķma.  Algengt er aš į Höfušborgarsvęšinu męlist aukinn styrkur PM10 mengunar vegna sandroks frį Mżrdalssandi og nįgrenni ķ sterkum austanįttum. Einnig eru dęmi um sandfok noršan Dyngjujökuls (annaš dęmi september 2009), og mörg fleiri.

Skrįning sandstorma - vinsamlegast skrįiš sandstorma.

Particulate matter pollution

Particulate matter pollution has bad health influences, decreases visibility and, as other pollution, has a bad effect on the environment. 

Modeling

Modeling efforts are in progress, made possible by grants from the Icelandi Road Authority and OR.  More on modeling.

Traffic

Traffic is the main source of PM-pollution in Iceland (windblown dust and sea salt can be significant contributions at times).  Efforts are underway to model the effects of weather and other factors on the PM-pollution variations.

New year's Eve

Every New year's Eve Icelanders put on a great fireworks-show; with almost every houshold participating.  The PM-pollution reaches incredible values, 3-4 times the maximum values during the whole year, and 30 - 40 fold the normal peak concentration.

Dust plumes

The fine sediments deposited by glacier erosion and rivers are a prime source for wind blown dust. If the winds are fairly strong, and the weather is dry, increased PM10 pollution is measured in Reykjavik due to glacier till from the south coast.
