![]() ![]() Globally, people facing increasing risks of respiratory diseases due to smoke and dust in both occupational and industrial sectors. CO, CO 2, NO and NO 2, VOCs, O 3 and aerosol particles are the most important urban air pollutants in terms of emissions and impact on the environment and human health as well. Currently road traffic was the most used mode of transport, where a high amount of money is spent to improve air quality deterioration results from pollution and environmental effects of transport sector emissions. Urban atmospheric pollution has a well-known impact on acute and chronic respiratory disease and adverse health effects on cardiovascular system. Whereas some effects may be related to short-term exposure, others had to be related to long-term exposure. Outdoor air pollution contributed to various adverse health effects. It was concluded that high volume of traffic, transport consumption of fossil fuels and shortage of adequate public transport system was responsible for the high CO 2 level in the environment. CO 2 emissions from road traffic worldwide will increase by 92% between 19, where direct energy consumption and CO 2 emissions are increasing faster for urban than for rural households. Reports indicated that the on-road vehicle emissions constitute the major source of atmospheric CO 2 in urban areas. Worth mentioning that the international agreeable guideline of the ambient CO 2 is 350 ppm. Further research showed that the 270 Giga tons of anthropogenic carbon emissions over the past 200 years would have increased CO 2 concentrations from 280 to 380 ppm. Moreover, this increase in atmospheric CO 2 was attributed to the world’s expanding use of fossil fuels and is believed to be the main cause of global warming which affects negatively many physical, biological, and human systems. Introduction Recent investigations indicate that CO 2 concentrations in the atmosphere have risen from pre-industrial levels of 280 ppm to present levels of ~380 p.m. The findings of this research emphasize importance of taking action to reduce traffic emissions levels in Gaza City, in order to decrease health impacts that the public is exposed to.ġ. ![]() The public health questionnaire results showed that 63% of study population complain from cough and nasal congestion during walking at the streets and 91.8% of sample thought that traffic emission was the main source of air pollution in Gaza city. The research results revealed that the CO 2 levels at the study locations fluctuating between 291-608 ppm, moreover it was noticed that the CO 2 concentrations in the majority of the monitored sites were higher than the agreeable international level of CO 2 which is 350 ppm. A questionnaire was distributed randomly to pedestrians and drivers at Gaza city to evaluate traffic emissions and their health impacts. Levels of CO 2, humidity and temperature were monitored at the selected intersections during morning peak (7:00-8:30 am), off peak traffic hours (10:30 am – 1:30 pm) and afternoon peak (3:00 – 4:30 pm) by using Kanomax meter and multi-meter. The aim of this study was to determine the levels of Carbon Dioxide (CO 2) emissions from the motor vehicles and to investigate the correlations between CO 2 trends and the associated health impacts. Traffic emission is a major source of air pollution in most urban areas and it effects on public health. ![]()
