HC Deb 27 June 1989 vol 155 cc380-1W
Mr. Redmond

To ask the Secretary of State for the Environment what are the most recent figures and those for five and 10 years ago on the levels of acidification in rainfall(a) in Doncaster, (b) the three counties of Yorkshire and Humberside and (c) nationally.

Mrs. Virginia Bottomley

The data requested are provided only for 1988 in the table. Prior to 1986 no data are available for the region and there are insufficient to calculate a representative United Kingdom average. The Doncaster value has been interpolated from nearby rural stations which may not be representative of an urban area.

Annual mean precipitation weighted acidity in rainfall in u eq H+/litre
Data region u eq H+/litre pH
United Kingdom 25 4.6
Yorkshire and Humberside 58 4.2
Doncaster 73 4.1
