dc.description.abstract |
Higher levels of NO2 are a danger to human health especially for children. A seven day study was carried to find out the
ambient concentrations of NO2in 27 schools of Lahore with the help of passive samplers. In each school three sites were
selected, viz: laboratory, corridor and outdoors. After 7 days exposure the tubes were subjected to spectrophotometric
analysis. Results showed that the maximum values measured in laboratory, outdoor and corridors were 376µg/m3 ,
222µg/m3 and 77µg/m3 . Minimum values for laboratory, outdoor and corridors were 10µg/m3 , 20µg/m3 and 8µg/m3 .
Factors affecting these values were laboratory activities and proximity to main roads. These values were significantly
higher than the standard values defined by EPA. Therefore children in schools were at risk of developing health
complications. |
