ACID RAIN

Acid Rain
  • In the 1980s, the UK was described by Scandinavian countries as ‘the dirty old man of Europe’ due to high emissions ofsulphurdioxidefromindustrial sources causingtransboundaryacid rainMost of the UK sulphur dioxide comes frompower stationsand other industries whilst the largest source of nitrogen oxides isroad transport and power stations. The UK experiences typical impacts from acid rain. In 1995, the United Nations Economic Commission for Europe (UNECE) Forest Survey revealed that 42% of UKtreeswere healthy, 45% were slightly defoliated and 13% were damaged. Both coniferous and broadleaf trees showed the same degree of damage. Freshwater acidificationis a serious problem in susceptible parts of the UK.

  • The main pollutants affecting materials are sulphur dioxide and sulphates, nitrogen oxides and nitrates, chlorides, carbon dioxide and ozone. The effects of paniculate matter, especially from diesel vehicle emissions is of increasing significance. The materials most sensitive to pollutants are calcareous building stones and ferrous metals. Manifestations of damage include losses of mass, changes in porosity, discolouration and embrittlement.

  • As for government intervention this is up for debate. Charities like English Heritage and National Trust are the main organisations which actively conserve and preserve historical buildings and monuments - these are funded by donations from patrons and e.g.  the Lottery Fund.
  • · environment through funding English Heritage
  • · nominating places in the UK for World Heritage Site status
  • · protecting buildings of special architectural or historic interest by giving them listed status, which prevents them being demolished, extended or altered without permission
  • · protecting nationally important sites and monuments of archaeological or historic interest by giving them scheduled status, which protects them from being changed without permission
the government of u k has issued several acts to combat pollution
