EMISSIONS AND AMBIENT AIR-QUALITY TRENDS, CALCUTTA CITY - 1973-1993

Traffic emissions in Calcutta have increased sharply and the resulting impact is threatening human health and damaging buildings such as the Victoria Memorial Hall in Calcutta. Ambient concentrations have been monitored around this building and a model has been developed which de scribes concentration and deposition patterns as function of traffic e missions and abatement measures. Planting a green belt is the most eff ective counter measure to abate the impact of local emissions on Victo ria Memorial Hall.
