The Negative Effects Of Water Pollution - curious

August 12, by The Last Well. Water is a basic human need required for drinking, cooking, and cleaning. It is also heavily used in industry, agriculture, and electricity. While the importance of water is undeniable, many companies and people continue to pollute our oceans, rivers, and lakes with harmful toxins and contaminants. In turn, water pollution has become a major crisis in countries across the globe, affecting millions of people worldwide. Water pollution has many causes, starting with rapid urban development. The Negative Effects Of Water Pollution

The water contamination or hydric is any alteration of its physical-chemical or biological characteristics harmful to the environment and life. It is also called water pollution, and is determined by the presence of pollutants. Pollutants can be chemical, physical or biological, of which chemicals are the most common. These reach the water through discharges, spills, wastes and direct or indirect deposits, causing damage to the organisms that inhabit or consume it. Water pollutants include detergents, oils, petroleum and its derivatives, fertilizers and pesticides, heavy metals, and plastics. The main sources of pollution are large cities, industries, oil activity, mining, agriculture, and traffic by seas and rivers.

To solve the problem of water pollution, the solution is complex and includes carrying out scientific research and public awareness campaigns. In addition, adequate wastewater treatment must be carried out and strict environmental regulations must be established. In Latin America there are serious water pollution problems, which mostly come from untreated urban and industrial effluents and mining. In Mexico, the north of the country is one of the areas with the highest water pollution due mainly to heavy metals. In this area, the sources of contamination are urban, industrial, mining and agricultural effluents. In Colombia, water pollution comes basically from urban effluents and agricultural activity. Argentina is another Latin American country highly affected by water pollution from agricultural and urban activity.

On the other hand, in some provinces, mining causes serious problems of contamination by heavy metals. Most of the rivers in Peru show some degree of contamination by heavy metals. Among the main sources of pollutants in the country are mining-metallurgical, urban, industrial, agricultural activities and the exploitation of hydrocarbons. Pollution from fish farming and copper mining waste affects Chile's water bodies.

In addition, other sources of contamination of Chilean waters are urban and industrial effluents. On the European continent, Spain has serious water pollution problems due to agricultural activity and the discharge of untreated sewage. For Asturias, pollution from mining activity stands out, and high levels of drugs have been detected in the Ebro river.

A water pollutant can be both a foreign substance to the ecosystem in question, as well as its own component. Wager example, phosphorus and nitrogen are very important in nature, but in excess they can cause eutrophication. In short, a pollutant is any substance that alters the properties or composition of water and affects its usefulness for life. These are the soaps and surfactants that reach water bodies through untreated sewage.

The Effects of Water Pollution On Human Health

Detergents are among the most life-threatening pollutants, breaking the surface tension of cell membranes. Additionally, detergents contain other water polluting substances such as antiscale, amines, bleaches, antifoams, colorants, perfumes, bactericides and enzymes. Among the negative effects of detergents are the diffusion of oxygen and the increase in the amount of boron perborate as bleach and phosphates in the water.

Oils and fats have the property of being less dense than water and immiscible with it Ppllution do not dissolve in water.

How You Can Make a Difference

For this reason, once they are discharged into bodies of water, they become serious pollutants. This occurs because they form a superficial film that prevents the diffusion of oxygen, which results in the death by suffocation of many marine organisms. Many household items are made of plastic, such as containers and bags that become waste. Furthermore, plastic in most of its presentations biodegrades very slowly.]
