INTRODUCCION
Smog is air pollution that reduces visibility. The term "smog"
was first used in the early 1900s to describe a mix of smoke
and fog. The smoke usually came from burning coal. Smog
was common in industrial areas, and remains a familiar sight
in some cities today.
Los Angeles is a city notorious for its smog, a combination of
particle and ozone pollution. The prevalence of these
pollutants result from many factors, including the burning of
fossil fuels, especially by vehicles, ships, planes and
manufacturing, as well as wildfires.
Los Angeles is not the only place with an air pollution
problem. In many European cities, a rise in diesel vehicles
has contributed to high levels of air pollution. Developing
countries like India and China continue to experience high
levels of air pollution as a result of rapid industrial growth and
weak regulation.
CAUSES
Smog is formed by mixing air with
pollutants and exhaust gases resulting
from human activities. The factors
which are responsible for this include
factories, an increasing number of cars.
pollution is caused by things such as
factories, power plants, cars, airplanes,
chemicals, fumes from spray cans, and
methane gas from landfills, but the
ways that humans caused the most air
pollution is by burning fossil fuels.
Effects
it causes serious health problems
ranging from minor irritations,
coughing, and wheezing, to asthma
attacks. Breathing in particle pollution
can also contribute to heart attacks,
strokes, and even premature death.
