What is nutrient pollution?

nutrient pollution is a type of water pollution that occurs when the presence of too many nutrients causes damage to the environment. The most common effect of this type of pollution is the death of fish and other water life. Nutrient pollution is often due to nitrogen or phosphorus release into water. They are not directly toxic to fish, but they cause disturbance of ecological balance in a complex process. The drainage of nitrogen and phosphorus is associated with agricultural practices, which is one of the reasons that agricultural areas are the most common places of nutrient pollution. When stimulating the presence of excess nutrients, these eyelashes can form mats on the water surface. When surface eyelashes die, less oxygen is made in water because the eyelashes under the surface do not get enough sunlight. If there is an oxygen hpoptávka in such a body of water in such a body of water, the oxygen level can drop to the extent that fish and other aquatic animals begin to die. This process is called eutrophication when it occurs naturally and artificial eutrophication, if it is caused by a source of nutrients caused by man.

excess nitrogen and phosphorus that cause nutrient pollution are usually the result of agricultural activity. Nitrogen is used in fertilizers and is present in animal waste from feed operations. Phosphorus is also part of farm fertilizers or treated waste water. Usually these elements, which are necessary throughout their lives, occur only naturally in limited quantities. In the same way, these fertilizers increase crop growth can cause growth or overgrowth of algae associated with cases of nutrient pollution.

One of the important examples of the process is the so -called dead zone, which occurs every year in the Gulf of Mexico. The dead zone is caused by nitrogen transmitted to the Gulf from the Mississippi River. Mississippi releases a large part of land in the Midwest United States, an area known for its agricultural operations and agriculture. In the Gulf of MexicOther nitrogen of eyelashes, which die and exhaust oxygen in the water. Fish and molluscs that cannot escape the zone are killed.

Although it may be difficult to end all cases of nutrient pollution, mastering such cases involves ensuring that too many nutrients do not enter the waterways in the first place. Some ways to achieve this include reduction or better control of the use of nitrogen fertilizers, the use of soaps that do not contain phosphates, and improve water treatment methods.
