This is because a decline in coal burning in the Northern Hemisphere has reduced emissions of sulphur dioxide aerosols.

For 89 years its giant plant has blanketed the capital with smoke and sulphur dioxide.

They are also better equipped to remove sulphur dioxide and other noxious gases.

Power stations burn coal at a higher temperature and produce less sulphur dioxide but also significantly less soot.

J. Ausubel and P. Waggoner, 2009 As America got richer in the the 20th century, emissions of sulphur dioxide rose.

They work in the same way as America's sulphur-dioxide trading scheme and Europe's emissions-trading scheme for carbon.

Some sulphur dioxide is. liberated when coal, heavy oil and gas burn, because they all contain sulphur compounds.

The government has set a modest goal of cutting sulphur dioxide discharges by 10 per cent to less than 23m tons by 2010.

The government has set targets to cut chemical oxygen demand and emissions of sulphur dioxide by 10% between 2006 to 2010.
