| dc.description.abstract | Continuous measurement of nitrogen oxides (NO and NOx) and ozone (03) were carried out by Air Pollution Monitoring Mobile Laboratory at a sampling lite located in the Sindh Industrial Trading Estate (SITE) of Karachi. The average concentration of NO was found to be between 7.1 to 69.9 ppb, No,. 17.2 to 83.5 ppb, and 0, from 7.5 to 19.1 ppb. Ambient concentration of NO, NOx. and O3 are strongly inter related and their dispersion condition are also discussed. The results obtained at SITE are compared with the data obtained at other industrial areas of Karachi and with the data generated at an uptown area of Karachi, which shows clear formation of ozone during the day time. It is evident that the formation of ozone is dependent upon the time lag in the photochemical process. | en_US |
