Pollution may be defined simply as the introduction of substances that may contaminate the environment causing it to be unstable, disorderly, harmful or uncomfortable to the ecosystem (Tennessee Department of Environment and Conservation, 2002). Water pollution therefore is the…
Water may be polluted when pollutants come from point or non-point sources. Non-point sources include those sources that are non-discrete or that do not originate from one discrete source. Non-point pollution arises from the cumulative effect of contaminating agents in little quantities over a large area. When nitrogen compounds found in fertilizers, herbicides, pesticides and other agricultural products leach out, it can easily cause pollution. Sheet flow over land used for agriculture may lead to pollution of water as the nutrients that were present in soil runoff in storm water. Point sources of pollution are those sources that come from discrete sources. For example, when a manufacturing company discharges hot water from its cooling system into a river, lake or other water body making the water body to become warm, pollution occurs from a point source.
There are a wide range of agents that may cause water pollution. Some of these pollutants include pathogens, chemicals, and physical changes to the natural characteristics of water. While some minerals naturally occur in water, when their concentration in the water goes beyond the natural limit, the water is considered to be contaminated. Also, when substances that cause oxygen to be depleted in water such as man-made chemicals, grass and leaves, water pollution occurs.
Pathogens or disease causing organisms such as Salmonella, Giardia lamblia, Burkholderia pseudomallei, and Cryptosporidium parvum may get into the water when waster water or sewage is not adequately treated (Tennessee Department of Environment and Conservatio, 2002). Chemical contaminants of water may include detergents, petroleum hydrocarbons, volatile organic compounds (VOCs), products used for disinfection and waste from tree logging operations. Inorganic water pollutants include sulphur dioxide that is ...

These substances change the characteristics of the environment thereby posing a threat to the existence of humans, animals and other organisms. These pollutants can be primary or secondary in nature. Primary pollutants includes those which are directly released into the atmosphere such as from power generating plants while secondary pollutants are those which result from the chemical reactions that occur between the primary pollutants and the other elements present in the atmosphere resulting in their transformation to secondary type pollutants (Air pollutants General Overview).
Pollution Pollution is caused when air, water or soil gets contaminated by discharge of harmful substances. Pollution causes imbalance in the ecosystem by causing harm and discomfort to living organisms. Pollution can be prevented if resources like raw materials, water and energy are utilized in proper way and harmful materials are substituted by materials which are less hazardous (“What is Pollution Prevention”, n.d.).
This caused increased demand for energy that saw the exploitation of oil, coal and natural gas sources at increased rates around the globe. In the UK for instance, Kaiser and Pulsipher (2007) approximate the number of oil and gas installations at 289, two of which are found in deep water.
Water is a chemical compound that is formed by bonds between oxygen and water molecules. Its property as a universal solvent however leads to many dissolves matter in it and this defines its pollution when the dissolved matter is harmful.
Pollution is in a word the neglecting of the environment and each other. It can be seen as disrespect for each others health. The reason that understanding pollution in terms of its implication on health issues is that it can help educate people. And as the saying goes: knowledge is power.

The document on air quality standards tells about the extent to which the policies are made regulated so that there is no or minimum pollution caused by non natural entities.
However, other states have a right to innocent passage in the territorial waters. Disputes arising on the right to innocent passage in territorial waters are many and two such cases, the Corfu Channel case and the Anglo-Norwegian case are evaluated with respect to the regulations in the different articles of International law.
