Seven air pollutants, SO2, H2S, CO, O3 , NOX, NH3 and PM10, in addition to basic meteorological parameters (wind speed, temperature and relative humidity) were measured in a residential area in Aqaba. Measurement took place during the time interval 31/12/2014 through 31/12/2015. Following ambient measurement, data were analysed to detect correlations between each air pollutant with meteorological parameters. Our findings showed that atmospheric concentrations of H2S, CO, NOX and NH3 positively correlate with relative humidity, but PM10, SO2 and O3 negatively correlate with it. Air temperature is found to enhance the creation of ozone. It is also found that the concentrations of PM10, NH3, NOX and CO increase with both air temperature and wind speed. However, concentrations of SO2 and H2S decrease when air temperature or wind speed increases. High wind speed leads to a higher mixing rate and improved dispersion resulting in lower levels of air pollution.

Abstract


Seven air pollutants, SO2, H2S, CO, O3 , NOX, NH3 and PM10, in addition to basic meteorological parameters (wind speed, temperature and relative humidity) were measured in a residential area in Aqaba. Measurement took place during the time interval 31/12/2014 through 31/12/2015. Following ambient measurement, data were analysed to detect correlations between each air pollutant with meteorological parameters. Our findings showed that atmospheric concentrations of H2S, CO, NOX and NH3 positively correlate with relative humidity, but PM10, SO2 and O3 negatively correlate with it. Air temperature is found to enhance the creation of ozone. It is also found that the concentrations of PM10, NH3, NOX and CO increase with both air temperature and wind speed. However, concentrations of SO2 and H2S decrease when air temperature or wind speed increases. High wind speed leads to a higher mixing rate and improved dispersion resulting in lower levels of air pollution.
