%X The increase in the urban population and the high
concentration of many anthropogenic
activities in certain regions of the world lead to atmospheric disturbances.
The excess concentration of several chemical elements leads to air pollution.
In order to identify the types of air pollutants, a study was carried out in
the city of Lom¨¦, the capital of Togo. The objective of this study is to achieve a better knowledge of the types of air pollutants
in the city of Lom¨¦. The identification of the various atmospheric
pollutants linked to the sources of pollution was made using micro-sensors. The
standardized method was used to access target gas concentration levels. The
average concentrations of NO2 gaseous pollutants at landfills are on
average 0.333 ¦Ìg/m3; 0.403 mg/m3 at the industrial level,
at the transport level they are on average 0.434 mg/m3 for the
morning and 0.457 mg/m3 for the evening. Concentrations of carbon
dioxide (CO2) are higher in industrial areas than in others sources of pollution. The average concentration measured at this level is 1632.79 mg/m3.
In terms of road transport, in the mornings the average concentration is
1493.23 mg/m3, in the evening the
average concentration is 1354.09 mg/m
