The Atmosphere and Air Pollution: Mexico City

William Williams         Page 1                           The Atmosphere and Air Pollution: Mexico metropolis The cash dispenser of the mankind consists of four main layers of various gases that bound the earth. The main components of the atmosphere are nitrogen, oxygen, argon, carbon dioxide, neon and atomic number 2 respectively (Earths Atmosphere).         The inward layer is the troposphere, which extends ab forth sevener miles out from the earths surface. This layer contains the elements to maintenance life and is where weather occurs. The stratosphere extends from nigh seven to thirty-one miles out and contains ozone that acts as a guard from ultraviolet radiation. The mesosphere extends from thirty-one miles to about fifty-six miles out. The thermosphere extends to outer seat (Kaufman and Frantz, 2000, p. 249). Primary pollutants are those released directly into the atmosphere. In Mexico urban center many of the immemorial pollutants are carbon monoxide, siemens oxides, nitrogen compounds and particulate matter (Urban Air Pollution in Mexico City). A primary coil pollutant in the air may pit with another primary pollutant or atmospheric compound to chassis a collateral pollutant such as when nitrogen oxides react with oxygen at high temperatures to form ground train ozone. This phenomenon occurs in Mexico City (Chemical of the Week-Ozone). The major contributing source to topical anesthetic and regional air contamination is a phenomenon called Thermal Inversion, which occurs in the troposphere.

Smog is the facial expression used to describe a cloud of air pollution trapped by thermal eversion (Sources of Air Pollution). The Mexican Government recognizes the...
