Abstract: Recent health risk assessment studies have linked high levels of air pollutants to various negative health outcomes. The goal of this study is to quantify the levels of ozone (O3), sulfur dioxide (SO2), nitrogen monoxide (NO), Particulate Matter 10 micrometers or less in diameter (PM10) and nitrogen dioxide (NO2) in 2 Industrial/Residential zones, Jahra and Shuwaikh, and the residential area of Fahaheel, which are residential areas in the state of Kuwait. During the sampling, a total of 219,000 O3, SO2, and NO2 readings were collected from KEPA and analyzed by Openair, which is part of the RStudio Package. There were 100 and 242 O3 readings above the hourly authority limit in Jahra and Shuwaikh, respectively, likely due to traffic emissions. Similar to O3, 53 and 115 NO2 readings exceeded the KEPA standard in Jahra and Shuwaikh, respectively, possibly due to the discharge from vehicles in Shuwaikh. Similarly, roads and restaurants likely increased the level of gas in Jahra. Forty-six readings were above the KEPA limit in Jahra, possibly due to the power plant and water treatment station; therefore, the SO2 values in Shuwaikh were within permissible levels. There were 132 and 169 PM10 values above the guideline in Jahra and Shuwaikh, respectively, because of emissions from highways and dust. In the residential zone, 164 O3 values were above the allowable standard, which could be from highways. Similar to Industrial/Residential areas, traffic may have contributed to the 4,547 irregular readings in Fahaheel. Refineries and sand storm increased the PM10 and SO2 limits, which had 123 and 234 readings above the limit, respectively. According to the correlation analysis, a strong correlation was found between O3 and SO2, and NO2 and PM10, with R values of 0.979 and 0.989, respectively, in the Jahra zone. Moreover, NO2 had an insignificant negative correlation with O3 in Jahra and Fahaheel, with R values of 0.61 and 0.45, but the association was positive in Shuwaikh, with an R value of 0.49. Based on the USEPA, WHO, British Columbia and Australian Department of Environment standards, the irregular records largely occurred in the residential zone for NO2 and SO2. However, the O3 and PM10 levels in the Jahra and Shuwaikh zones were nearly equivalent to the levels in Fahaheel. The findings from the current study will help local environmental authorities further regulate air pollution levels and protect public health.
