Increasing SO2 gas pollution

Increasing SO2 gas pollution is now being detected in Kirkjubæjarklaustur on the south coast of Iceland. Measurements show between 1400 and 3300 microgram per cubic meter. 

Volcanic gases with possible effect human health are released into the atmosphere from the eruption in Holuhrauni. The most abundant gases are water ( H2O), carbon dioxide (CO2) and sulphur dioxide (SO2). Other substances such as hydrogen sulfide (H2S), hydrogen(H2), carbon monoxide (CO),  hydrogen chloride (HCl), hydrogen fluoride (HF) and helium (He) are also released, but in smaller amounts.
