Does Acid Rain happen in Gladstone?
No. Acid rain is formed when there are both moisture and a high concentration of either sulphur dioxide or nitrogen dioxide in the atmosphere. Concentrations of at least 0.2 parts per million (PPM) nitrogen dioxide or 0.1 to 2.0 PPM sulphur dioxide are required to form acid rain. CHAG monitoring results typically show concentrations of nitrogen dioxide or sulphur dioxide at up to 0.03 PPM in Brisbane and 0.02 PPM in Gladstone. Gladstone’s maximum concentrations of sulphur dioxide and nitrogen dioxide are therefore about a 10th of the minimum concentrations required to form acid rain.
