The effects on human health resulting from the January to April 1998 haze-related air pollution episode in Brunei Darussalam were analysed for five groups of diseases of the respiratory system. The analysis concentrated on the statistical estimation of dose-response functions which related the number of cases of respiratory diseases to the level of quality of ambient environment as measured by the pollutants standards index (PSI) and other environmental variables. The total number of cases of the five groups of diseases was shown to be significantly related to PSI and temperature. Societal costs were also estimated. The results showed that societal costs were significantly related to PSI, temperature and relative humidity. Societal costs increased with higher PSI and relative humidity but decreased with increasing temperature.
