Background: Japan -- and 1,500 researchers and experts on environmental pollution representing 40 countries, are in Tokyo this week for the fourth International Clean Air Congress.
Japan has also adopted strict measures to control automobile exhaust emission of nitrogenous oxides. Research and development efforts are aimed at bringing the level down to 0.25 grams per kilometre. According to Japanese authorities on the subject, the most important problem facing them is how best to control nitrogenous oxides, as pollution through sulphurous oxides has been kept in check.
SYNOPSIS: The five-day conference, sponsored by the International Union of Air Pollution Prevention Association, began on Monday (16 May). Intensive discussions will be conducted throughout the week in six separate sessions. The topics for debate include -- medical and biological effects from pollution, meteorology and diffusion of pollutants, and air pollution and control technology. Delegates will also visit factories and research institutes in and around Tokyo.
The host country for this year's congress has been waging a campaign against pollution for some time. Japan spent an estimated 40 million U.S. dollars last year on pollution control technology. And not without reason. The industrial suburbs of Tokyo are badly affected by air pollution, but with the introduction of techniques which reduce the amount of sulphur in industrial effluent, the amount of toxins in the air has been declining.
