| dc.description.abstract | As part of a screening study to develop a plan for ambient air pollution monitoring in Zambia, 20 SO2 and 10 NO2 passive samplers were placed inside Lusaka, Ndola and around industries in the Copperbelt area. The passive samplers were installed in field to measure ground level concentrations as a result of emissions from traffic and industry. SO2 is particularly a problem in the Copperbelt area, due to the high industrial activity that characterises this area. The World Health Organisation’s (WHO) air quality guideline for SO2 is exceeded in Luanshya, Mufulira and Nkana, downwind from the smelters. While in Luanshya and Mufulira these concentrations can have a serious impact on both vegetation and the populations leaving downwind from the smelters, in Nkana the population is less often exposed to extremely high SO2 concentrations, since the townships are not located on the prevalent downwind direction from the industry. The measured NO2 concentrations are well below the WHO air quality guideline and do not represent presently a motive of concern. | |
