    Abstract:
    A study of 4 comparable communities in central & northeastern Bombay (2 each) among randomly matched 349 subjects in 1988-9, along with ambient sulfur dioxide (SO2), Nitrogen dioxide (NO2) & suspended particulate matter (SPM) air monitoring was carried out. The levels in winter were higher particularly for SO2 in Parel (upto 584 micrograms) in Maravali; Deonar showed lower pollution. There were inter-area differences for housing, income, residential history but age-sex differences were small; these were reduced by matching. Clinical respiratory symptoms were higher in Parel & Maravali (cough 12% and 11.2%, dyspnoea 17% & 13.3% respectively). Cardiac problems are commoner in Parel (11.0%). Smoker had cough more often but not dyspnoea. Maravali had a high prevalence for headache and eye irritation (9.5%). Those using kerosene suffered more than those using gas (22.2% as compared to 9.2%) Lung functions (FVC, FEVI) were lowest in Parel for males and in Maravali for females. Expiratory flow rates were lower at Dadar and then at Maravali. Despite lower SO2 pollution, Maravali residents suffered equally as in Parel. This may be due to added effect of diesel exhausts (NO2, SPM) or other unmeasured chemicals.
