Abstract
Eight primary criteria air contaminants were measured continuously for the year 2010 to evaluate ambient air quality in Al Jahra, which is one of the oldest and busiest cities in the state of Kuwait. The state of the art instrumentation was used to record the pollutants concentration to ppb levels maintaining quality control and quality assurance. Hourly base data for Non-Methane Hydrocarons (NM-HC), CH4, CO, CO2, O3, SO2, NO2 and Particulate Matter (PM10) were analyzed for year 2010. Meteorological parameters contributing to air pollution, such as (temperature, solar intensity, wind speed and direction) have also been considered. The effect of winter and summer seasonal changes on pollutant concentration levels were analyzed to identify the most probable sources for the application of the futuristic mitigation methods for pollution abatement. The obtained results consistently suggest that the foregoing pollutant concentration levels are higher in winter than summer due to poor dispersion and shallow inversion layer with the exception of O3, CO2 and PM10. However, all of the pollutant concentrations are below the allowable standards limits except for NM-HC.
Highlights
Air is one of the major components of the environment that has been abused by human reckless behavior due to renaissance and prosperity as part of urbanization causing what is known today as air pollution
According to World Health Organization (WHO) 1 of 6 people lives in polluted urban area, which is more than 1.1 billion people [1]
The ambient air quality data for two extreme seasons as hourly average concentrations and meteorological conditions were recorded utilizing monitoring stations fixed by Kuwait-Environment Public Authority (KU-EPA) at selected sites throughout the state of Kuwait
Summary
Air is one of the major components of the environment that has been abused by human reckless behavior due to renaissance and prosperity as part of urbanization causing what is known today as air pollution. There evaluations for the data were calculated to obtain annual hourly averages and annual 1-h maxima for each year for each pollutant as well as metrological parameter This way, the impacts of the seasonal variation (winter, spring, summer and autumn) of these pollutants and metrological parameters on the air quality of these urban areas in different seasons have been masked. The air quality data in Kuwait were collected using a fixed AQMS operated by KU-EPA, which measures continuously each 5 minutes the concentration level of various pollutants. This monitoring station is located above the main polyclinic in the middle of the residential area. The sampling site is selected on the basis of availability of power, security and elevated position
