17 January 2000 00:00 [Source: ICB Americas]The US has signed an international protocol to reduce air emissions of the pollutants that acidify lakes and streams, damage forests and cause smog. The targeted pollutants include nitrogen oxides, sulfur oxides, volatile organic compounds and, in Europe, ammonia.
The agreement, signed by 27 countries thus far, creates the first multinational structure to simultaneously reduce the long-range migration of the various pollutants that, in different combinations, cause acid rain, smog and other air problems.
The accord, which requires ratification by at least 16 countries, is the latest in a series of international protocols to advance scientific understanding and air pollution control throughout the North American and European regions covered by the United Nation's Economic Commission for Europe.
