Air Pollution and Acid Rains
A major problem with air pollution is that it does not obey national boundaries. The planet’s wind cycles and currents can carry pollution hundreds of miles away from its original source. So Britain is a large contributor to air pollution in Sweden and creates more for Norway than Norway does itself. The pollutants1 of the USA end up on the eastern coast of Canada.
Acid rain emerged as a concern in the 1960s with observations of dying lakes and forest damage in Northern Europe, the United States and Canada. It was one of the first environmental issues to demonstrate how the chief pollutants – oxides of sulphur and nitrogen – can be carried hundreds of miles by winds before being washed out of the atmosphere in rain, snow and fog.
As evidence grew of the links between air pollution and environmental damage, legislation to curb2 emissions was put in place. The 1979 Geneva Convention on Long-Range Transboundary Air Pollution set targets for reduction of sulphur and nitrogen emissions in Europe that have largely been achieved. The 1970 and 1990 Clean Air Acts have led to similar improvements in the USA.
Many nations have adopted air quality standards to safeguard the public against the most common pollutants. These include sulphur dioxide3, carbon monoxide, suspended particulate matter4, ground-level ozone, nitrogen dioxide and lead – all of which are tied directly or indirectly to the combustion5 of fossil fuels. Substantial investments in pollution control have lowered the levels of these pollutants in many cities of some developed countries. But poor air quality is still a major concern throughout the industrialised world.
Meanwhile, urban air pollution has worsened in most large cities in the developing world, a situation driven by population growth, industrialisation arid increased vehicle use. Despite pollution control effects, air quality has approached the dangerous levels, recorded in London in the 1950s, in such megacities as Delhi, Jakarta and Mexico City.
In some parts of Asia, such as Southeast China, Northeast India, Thailand and the Republic of Korea, and in the Pacific region acid rain is now emerging as а major problem. In the Asia region the use of sulphur-containing coal and oil is very high. In 1990 34 million metric tonnes of sulphur dioxide were emitted there, which is over 40 per cent more, than in North America. The effects are already being felt in the agriculture. In India wheat growing near a power plant suffered a 49-per cent reduction in yield. Other ecosystems are also beginning to suffer. Pines and oaks in acid rain-affected areas of the Republic of Korea showed significant declines in growth rates since 1970.
