Air Pollution levels measured in Egypt

EEAA/EIMP operates presently about 40 Measurement sites for air pollution in Egypt. Measurements
have occasionally recorded air pollution levels
exceeding the Air Quality Limit values as given by
Environmental Law no. 4 for Egypt. Cairo area also during the Autumn 1999 experienced
several air pollution episodes with air pollution
levels reaching very high concentrations due
different sources and adverse weather conditions

The air pollution problem in Egypt
The main air pollution problem in Egypt is the level of suspended particles.Particles in ambient air are measured as.
♦ Total suspended particles (TSP),
♦ Particles less than 10 micrometer in diameter (PM10),
♦ Black smoke (BS, soot) and
♦ Dust fall.
The measured concentrations often ranged from 6 to 8 times the Air Quality Environmental Law no. 4 for Egypt. It should be noted that the natural background level of dust in the atmosphere
higher than the Air Quality Limit level, due to the dry climate, windy conditions with re- uspended dust and large surrounding dessert areas. exceed AQL levels in urban areas and
close to industrial sources. The levels of NO2 seldom exceeded the AQL sources for pollution in urban areas.
