8,3 million tonnes of sulphur dioxide
The eruption at Holuhraun has released 8,3 million tonnes of sulphur dioxide since it started which means 50 - 60 thousand tonnes per day. In comparison, SO2 pollution in the countries of Europe is 14 tthousand onnes per day and 40 thousand per day in the US.
The gas pollution from Holuhraun is the largest since the Lakagígar eruption in 1783 which emitted 100 million tonnes over the period of eight months.
Meterologist Einar Sveinbjörnsson has been studying the pollution from Holuhraun and has pointed out that the gas is harmful and that not all the effects of SO2 on the lungs and the human body are known as yet.
