Abstract:

In this study, a health risk assessment for air emissions from a desalination plant in Saudi Arabia was carried out. Short-term health effects were evaluated for SO2, NO2, CO and PM10. BREEZE AERMOD was used to predict the ground level concentration (GLC) from the plant over an area of 50km by 50kmThe predicted concentrations were compared with the Royal Commission Environmental Regulations (RCER) and the findings indicate that the predicted concentrations were within the acceptable limits except for SO2 where 4-exceedances were recorded. Based on the health risk assessment, the Hazardous Quotient (HQs) for each pollutant were less than one and the HI was also less than one, implying that no adverse health effects on the area were expected. The maximum HQs for SO2, NO2 and CO were recorded at a distance of 2.75 km towards the northeast of the plant, while for PM10, the maximum HQ was towards the northwest at a distance of 1.9 km. The maximum health hazard (HI) was 0.23 at a distance of 2.75 km, with the highest contribution of SO2 reaching 70%. The respiratory system is the most affected organ, with a maximum value of HI reaching 0.22.
