The aim of study was to investigate the concentrations of the ambient air pollutants (i.e PM2.5, CO, CO2) and to examine the health impacts on the residentials living surrounding the power plant in Gaza City-Palestine.The pollutants were monitored several distance surrounding the plant for a period of four months during both summer and winter seasons using a portable laser particle counter and gaseous monitor. A public health questionnaire was also distributed on the residents living around the power plant in order to assess the impact of air pollution on their health status.The results showed that the concentration of particulate matter exceeded the WHO standard where the highest level was 79 ?g/m3 and the lowest level was 49?g/m3. However the concentration of carbon monoxide was lower than the WHO standards where the highest level was 2.18 ppm and lowest level was 0.1 ppm. Moreover, the concentration of carbon dioxide oscillated from 254 ppm to 514 ppm. The health assessment results showed that 50% of the study sample suffered of breathing difficulties.This study concluded that the concentration of particulate matter and carbon dioxide were high, while the level of carbon monoxide was low, furthermore the level of public awareness was good. Meanwhile 40% of population sample visited the hospital because of a disease that infects the respiratory tract
