Volcano In Iceland

How can I tell if there’s gas pollution on site?

Gas pollution is not visible and cannot be detected by scent. Gas can disperse from the smoke cloud and pollution can increase rapidly in an area. Gas pollution is strongest close to the area and can lurk in valleys and dells where it is particularly dangerous. People must always turn downwind. This means that people must have the wind in their back when walking towards the eruption site and go against the wind when walking back. Gas pollution is not visible and does not necessarily follow the visible gas cloud in the area. If you experience the slightest symptoms of health problems, you should immediately leave the area with the wind against you. Gas pollution can be odorless and it is, therefore, difficult avoid it.
