AIR POLLUTION
WORDS BY
Mariam Abdelwahab
Air pollution in general is
due to automobile
emissions is a major
concern in most fast
expanding cities in
developing and developed
countries alike. Vehicle
traffic volume and
associated emissions
obviously depend on a
range of factors such as
population size, fuel
consumption per capital,
the proportion of the
population owning motor
vehicles, annual average
distance traveled, the age
distribution of motor
vehicles, etc.
The degree of air pollution is
particularly problematic in
cities where smallsized
vehicles are the main means
of commuting and
transportation due to
insufficient mass transportation
alternatives. . Here, in Egypt
we suffer from almost all of
these problems. Statistics
proved that between 1996 and
2006, the population of Egypt
has increased from 59 to 73
million with an average annual
growth rate of 2.04% as well
as the number of motor
vehicles in Egypt was 3.4
million in 2003 and reached
5.8 million in 2010.
