Air Quality Status in Kinshasa as Determined by Instrumental Neutron Activation Analysis, Atomic Absorption Spectrometry, and Ion-Exchange Chromatography
Three independent analytical techniques: instrumental neutron activation analysis, atomic absorption spectrometry, and ion- exchange chromatography were applied to airborne particulates collected on filters, and to atmospheric acid gases collected in carbonate buffer solutions. Twenty trace elements and seven acid gases and acid aerosols were determined.
Results were compared with those observed elsewhere and showed that air pollution is low in Kinshasa and should not cause anxiety. The main known sources of pollutants are vehicle exhaust and aeolian processes on stripped soils.
