water and air pollution

By Edited Nov 13, 2013 0 0

Many businesses, in an effect to foster and encourage ethical behavior to their employees, often write down a code of ethics. This written guide or outline, details acceptable and ethical behavior as defined by the company. It may also include other policies and perhaps punishments too.

Water pollution takes on many forms. When the addition of materials renders water unusable, it is considered polluted. Examples of water pollution include point source and nonpoint source. An oil spill coming from the tanker is an example of point source pollution. The spill takes place at the source. Point source pollution is easier to monitor and regulate that nonpoint source. Agricultural runoff, resulting from fertilizers, pesticides, insecticides and other chemicals that are carried off the fields into rivers and lakes by rain, is an example of nonpoint source pollution. Other causes of water pollution include sewage. Often cities and municipalities are the largest contributors of this type of water pollution. The city of Milwaukee serves as a horrendous example of sewage pollution. Every time their water treatment plants take on too much water due to heavy and prolonged rain, the city officials simply discharge huge volumes of untreated human sewage directly into Lake Michigan. Other causes of water pollution include radioactive substances and heat. Heat is often overlooked as a cause of water pollution that destroys aquatic life due to the sudden change in water temperature. This can occur when a discharge of cooling water by certain factories and power plants takes place. It is smart to find somewhere else to dispose of this chemical filled water that could be toxic for humans.

There are two causes of air pollution, natural and human. Natural causes would include volcanoes, forest fires, wind erosion, pollen dispersal, and naturally occurring radioactivity. Human causes of air pollution can easily be narrowed to two main sources. Fuel combustion that takes place within a stationary setting such as industrial, commercial and residential heating and cooling and coal burning power plants. And the second source being transportation, predominately automobiles that run on combustible engines. When automobile exhaust and the burning of high sulfur industrial fuels combine with atmospheric moisture, the result can lead to another form of pollution. Although it is pretty hard to cure natural pollution, it is possible to minimize human pollution.

Acid rain, a form of precipitation that contains high levels of sulfuric or nitric acids can contaminate ground water, damage aquatic life and lead to erosion. Besides the human cause of acid rain, nature, through volcanic gases and forest fires also is a significant cause of acid rain.

With pollution comes waste and waste disposal is an ever widening concern. Land fills are one way to deal with the waste. Incinerators are another method but leave behind toxic ash that still has to be dealt with.

The Equal Employment Opportunity Commission was created with the ability to investigate employment discrimination complaints and has the power to sue companies that practice it. Within this role, enacted by Congress, it serves to deter work force discrimination. If you are a cause of human pollution, think about the changes that you make to make the air quality better to live in.
