Introduction Air pollution is one of the forms of pollution that affect the environment negatively. Air pollution results from chemical emissions from companies and human actions that pose health risks to individuals as well as to the environment. Furthermore, air pollution may destruct the ozone layer leading to global warming. Though pollution is virtually everywhere, the paper focuses on Houston, one of the major cities is the US that have unacceptable levels of pollutants that pose health risks to the lives of people, plants, and animals. It addresses the sources of pollution in general besides identifying a major air pollutant in Houston. Further, the paper will present the various bodies put in place to fight air pollution in Houston. Sources of Air Pollution In Houston, various sources of pollutants cause negative effects to the environment and human beings. Sources of these emissions include toxic pollutants, which are emitted to the environment from chemical manufacturing facilities that surpass 400 in number in Houston (Donaldson et al., 2004, p. 3). Two among the four largest refinery companies in the US include the port of Houston and the Petroleum Complex both of which are located along the Houston Ship Channel in Houston. Other companies that contribute to these emissions include dry cleaners, printing processes, coating process, restaurants, gas stations, gasoline fueled lawn maintenance equipment, and charcoal barbecues amongst others. Other important sources of these pollutants are tailpipe emissions that come from trucks, buses, and cars. These emissions are spread to the air. Often, they are inhaled by human beings unknowingly. Other particles from emissions diffuse into the air. These emissions from these companies have negative implications to the ozone layer in the higher atmosphere. When this layer is impaired by the particles, it becomes a health hazard causing global warming, which increases temperatures on the earth surface. Air Pollutants In Houston, various air pollutants cause environmental pollution. These air pollutants include “fine particular matter, 1-3 butadiene, the Ozone, asbestos, chromium VI, diesel particle matter, nine hazardous air pollutants, chlorine and hexamethylene diisocyanate, ethylene dibromide, acrolein, benzene, acrylonitrile, acrolein and formaldehyde” (Donaldson et al., 2004, p. 3) amongst others. The Ozone air pollutant has high effects on the environment as well as on the health of the people, as revealed next. The Ozone The Ozone is one of the air pollutants that have raised a lot of concern in Houston for a number of years. The Ozone is a form of gas that usually reacts under the influence of light. Ozone is a two-fold substance implying that it has two layers: one in the high atmosphere and the other one at the ground level that is mostly considered as a pollutant. This air pollutant continues to affect the health of people in the city of Houston. Measures have been put in place to ensure that the prevalence of ozone gas is minimized. Therefore, the danger inherent in this air pollutant has triggered relevant stakeholders to come up with ways of reducing its levels in the environment (Lezon, 2012, p. 2). The most dangerous areas are Brazoria and Galveston in Houston. What compelled the issuance of this alert were the atmospher
