SOx
Sulphur Oxides
What is it?
Sulphur dioxide (SO2) is found in the atmosphere either in gas or in solid form. It is a sulphur and oxygen containing compound and is the most abundant of the group of compounds called sulphur oxides (SOx).
Where does it come from?
SO2 is emitted by the burning of coal and oil, and by the processing of sulphur-containing mineral ores.
In Ireland, most SO2 pollution comes from the burning of coal and oil to heat homes and produce electricity.

Why is it harmful?
Short-term exposure to SO2 can harm the respiratory system and make breathing difficult. This is especially true for people with asthma, in particular children.
When does it cause the most harm?
High SO2 levels are of most concern during winter months as many households rely on the burning of solid fuels to heat their homes.
Fuel regulations – increased use of natural gas an low-sulphur “smokeless” coal have led to significant reductions in SO2 emissions and related health and environmental effects.
