摘要

Rwanda is a landlocked republic in Equatorial Africa. The capital Kigali (1°57'S, 30°04'E) can be mentioned as a typical African city due to its rising population and the rising rate of motorization. Different pollutants produced e.g. by a high-usage rate of mopeds or open fireplaces burning woods for cooking and household chores could be detected. Climatological parameters as well as air pollutants were measured within the urban area. Additionally highly frequented spatial and temporal mobile measurements of particulate matters were taken during the dry spells of 2008 and 2009 regarding different conditions. These values indicated an UHI, which tended to rise from 1971 till 2009. Also a temporary phenomenon for the air pollution indicators is visible during clear and calm weather situations, e.g. the distinctive relief caused an accumulation within small valleys called "Marais" in the night time. Unfortunately, these are the favorite places of living and agriculture. So there is no infrequence in values of PM_(10) > 1.000 μg m~(-3). The origin of the different airborne particles was verified by using a scanning electron microscope (SEM) and it could be mentioned that most particles were from the combustion of biomass fuels and traffic.
