What Are the Causes of Environmental Pollution?



Environmental pollution is the introduction of contaminants into the environment that makes the environment unhealthy for habitation and on the extreme, can harm the ecosystem. The causes of pollution depend on the type of pollution under view.

Air pollution This is the release of polluting chemicals and particulates into the atmosphere. These pollutants makes it unhealthy to breathe in such air. Common air pollutants are sulfur dioxide, chlorofluorocarbons (CFC), carbon monoxide, and nitrogen oxides produced by industry and motor vehicles. When hydrocarbons and nitrogen oxides react to sunlight, smog and photochemical ozone are formed when nitrogen oxides and hydrocarbons react to sunlight.

Water pollution When waste products and potential contaminants are released into river drainage systems and other water bodies making the water unfit or compromising the quality of the water for use by man or habitation of water fauna and flora, we have water pollution.

Soil Contamination occurs when chemicals are released by spill or underground leakage. Among The most significant soil contaminants are hydrocarbons, heavy metals, herbicides, pesticides and chlorinated hydrocarbons.

Radioactive contamination, resulting from 20th century activities in atomic physics, such as nuclear power generation and nuclear weapons research, manufacture and deployment.

Noise pollution, which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.

Light pollution, includes light trespass, over-illumination and astronomical interference.

Visual pollution, which can refer to the presence of overhead power lines, motorway billboards, scarred landforms , open storage of trash or municipal solid waste.

Thermal pollution, is a temperature change in natural water bodies caused by human influence, such as use of water as coolant in a power plant.

Lesser-Known Effects of Pollution



Pollution is the introduction of elements into any environment that upset the equilibrium of the environment and cause instability, discord or harm.

Pollution can take many different forms: air pollution, water pollution, soil contamination, radioactive contamination, noise, light, visual, and thermal pollution are a few of the well-known forms of pollution.

The main effects of pollution have been well documented and debated. Higher incidences of respiratory and cardiovascular ailments caused by air pollutants have become ubiquitous and alarming. A very high number of deaths in developing countries are due to the consumption of contaminated water. Hearing loss, high blood pressure, sleep disturbances, cancer, and birth defects are some other effects of different forms of pollution.
Over and above these "usual" effects of pollution, some lesser-known effects have also started emerging. For example, a recent study links air pollution to low IQ in children. Researchers have established that mothers who breathe in air with higher pollution levels during their pregnancy are likely to bear children with lower IQs. The implication of this study seems to be that while toxins pollute the environment as a whole, they also pollute our bodies and make us mentally slower. Chemicals, preservatives, and additives that go into packaged food, and pesticides that go into natural food, all qualify as pollutants.

Another study claims that air pollution appears to cause genetic changes that make infants more prone to asthma in later life. The researchers believe that air pollution induces changes in gene expression without changing the structure of the gene itself. While there has long been a link between pollution and the higher incidence of asthma, the effect on a gene is definite cause for concern.

Types of Environmental Pollution



Pollution is the result of progression and development that is occurring on a regular basis. With the growth of technology more and more development is taking place in order to improve the quality of human life. This series is certainly giving high level of comfort and a rich lifestyle to all humans but is sadly diminishing the worth of human health; the need to have a good and healthy environment is ignored.

Many new inventions and introductions are causing a danger to human life as they are done artificially. This artificial and unsystematic way of generating high level of comforts is producing components that are inevitable to human life. Be it any thing including the basic needs of life like clothing and even food is now being produced synthetically. Just one insight into the depth of ecology will make us realize that the increasing need of the present day lifestyle is eventually creating an imbalance in the ecology.

Here are some of the most common types of environmental pollution that are gradually bringing people to a morbid stage:

Noise Pollution

Any kind of noise that is unpleasant to human ears is considered as noise pollution. Loud and hard sounds coming from factories, machinery, automobiles, trains, fire crackers, and explosives are also contributing to noise pollution. It is also caused by some natural calamities like harsh winds and volcanic eruptions. Both natural and artificial factors contributing to noise or sound pollution have their impact on human health. This kind causes irritation, hearing issues, and headache. However these are not major issues but extremely unpleasant sounds can be very harmful as they can cause an increase in the cholesterol, constrict arteries, an increase in the flow of adrenaline, and also forces the heart to function at a faster pace. All these can be life threatening as these factors can lead to heart attacks and strokes.

Water Pollution

Any kind of harmful components or contaminants entering the water bodies like river, oceans, lakes, ponds, and streams cause water pollution. Many human activities like washing cleaning, and dumping waste significantly contribute to water pollution. The soaps and detergents used these days are also made of harmful chemicals and synthetic materials that produce more contaminants in water. Furthermore, dumping waste like cans, bottles, and plastic materials also pose danger. It not only destroys marine life but is also hazardous to human life. This kind of polluted water is not safe for drinking, agriculture or even industrial use.

Air Pollution

Air pollution is caused by discharge of harmful substances in the air. One of the key contributing factors is automotive pollution. With the growing technology, the number of vehicles on road is dramatically increasing which is eventually giving a pushing up the level of air pollution. Apart from this, industries indulged into thermal power plant, cement, steel, mines, petro-chemicals, and steel also generate harmful substances that are released into the atmosphere. This kind of pollution has caused harm to the protective ozone layer in the atmosphere. This layer protects the earth from the harmful effects of ultra-violet rays but thinning of this layer is causing a danger to human life.

Radioactive Pollution

Radioactive pollution is a rare kind but is detrimental. It is caused by accidents in the nuclear power plant, improper disposal of nuclear waste, and operations of uranium mining. Radioactive pollution causes cancer, various kinds of birth defects, and many other serious health issues.

Soil Pollution

Soil pollution, also known as land pollution, is defined as the contamination of soil. These days many artificial substances and synthetic pesticides are used for agriculture. Such substances release contaminants that create an imbalance in the soil and also prevent natural growth of the plants cultivated on polluted land. Key factors contributing to soil pollution are sewage pills, hazardous waste, non-sustainable agriculture practice, use of inorganic pesticides, deforestation, strip mining, and certain human activities like dumping and littering.
