Ambient air.the major source of increase in the air pollutant concentration in the ambient air are due to rapid industrialization and urbanization along with the automobile emission. Hence, the present study the ambient air quality has been monitored for NOX, SO2, PM10, PM2.5 and indoor microbial pollutants such as bacteria and fungai. Their sources include both anthropogenic and natural sources. This study deals with measurement of ambient air quality in the hospital environment for different

High volume air sampler was used for monitoring, particulate dust sampler and microbial air sampler for bacteria and fungi. The various meterological parameters such as wind speed, wind direction, temperature, humidity, precipitation are considered for the different seasons. The experiment was carried for ambient air quality monitored for for NOX, SO2, PM10, and PM2.5 in μg/ m3 at four different location around the hospital area .location (1) front gate, location (2) entrance, location (3) car parking area, location (4) scooter parking area for the three different seasons like winter, pre-monsoon and monsoon. It was found that all the pollutant concentration was within the standards expect the PM10 which was exceeding the NAAQ standards 136.2 μg/ m3 in winter may be due to more vehicular traffic. The pollutant concentration decreases in monsoon season due to the precipitation, wind speed and humidity. The vehicular count was done for the 24hour the maximum volume was during 9AMto12am and 4M-8PM, the vehicular emission contributes the major source for pollution. The bacterial and fungal samples were collected and characterized to identify and isolate the different species of microorganisms present in the different wards of JSS hospital, the bacterial concentration in CFU/m3 was measured at different wards like General ward, lobby, maternity ward , ICU of JSS Hospital and found more at General ward 135 CFU/m3. And the bacterial and fungal concentration depends on the number of people and hygiene condition in the hospital. Prediction of air pollution dispersion using CALINE4 model for pollutant concentration such as NOx and PM10 with the input corresponding meteorological parameter like temperature, wind speed, wind direction is collected for different season. Results of CALINE4 Model for PM10 concentration was found to be marginally over-predicted than the actual field monitored data during the study period (i.e., from December, 2016 to June, 2017) .NOx prediction from the CALINE4 Model was found to be under-predicted when compared with the field monitored data. This may be due to the presence of atmospheric nitrogen in the ambient air which also contributes to the field monitored NOx concentration. Wastewater.
