Abstract: - Today’s environmental issues are systematic in nature and cannot be tackled in isolation from man-made activities and impacts. The change in land use and land cover resulting from urbanization has aggravated air quality in urban centers of the country. One of the main sources of air pollution is the use of automobiles in human populated regions resulting in an excess of carbon, sulfur and nitrogen compounds. The emission of greenhouse gases in the form of carbon dioxide from 1990 to 2005 showed an increase of 97.4%. The main source of this increment were vehicular and industrial emissions due to which Pakistan is facing glacier melt in northern areas, earthquakes, flooding and lack of fresh water availability. The authors analyze the effects of vehicular emission on human health; this study is focused on the commercial and industrial areas of Karachi where the flow of heavy traffic and heavy vehicular exhaust emissions are common. The sampled areas are Port Qasim, University Road, Korangi and Mosmiyat. The purpose of this study is to evaluate perceptions of health factors due to air borne pollution in 4 different localities in Karachi. The results showed predominance of headache which is due to an excessive quantity of carbon monoxide and air borne dust in the survey areas as slight exposure of Carbon monoxide affiliated with headache, the second highest complain from respondents is the Eye Irritation, the exposure of NO2 has acute health effects which include eye irritation, cough and asthma. Based on the above study, recommendations are made to reduce GHG and other pollutants.
