Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. Read here more about 40 facts of air pollution.

A physical, biological or chemical alteration to the air present in the atmosphere is referred to as air pollution. Air pollution occurs whenever any harmful gases, dust mites, smoke or smog enters into our atmosphere and makes it difficult for plants, animals, and humans to breathe as the air becomes toxic and contaminated. Air pollution can be caused by primary sources or secondary sources. Primary air pollutants are the ones that are a direct result of the process causing air pollution. A popular example of a primary pollutant is the sulphur dioxide emitted from factories and industries.

Causes, Effects, and Solutions for the Woes of Air Pollution on Human Life

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution is often classed as point source or nonpoint source pollution. In , pollution killed 9 million people worldwide. Major forms of pollution include air pollution , light pollution , litter , noise pollution , plastic pollution , soil contamination , radioactive contamination , thermal pollution , visual pollution , and water pollution. Air pollution has always accompanied civilizations. Pollution started from prehistoric times , when man created the first fires. According to a article in the journal Science, " soot " found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires.

Air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. It has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution. According to the World Health Organization, six major air pollutants include particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Long and short term exposure to air suspended toxicants has a different toxicological impact on human including respiratory and cardiovascular diseases, neuropsychiatric complications, the eyes irritation, skin diseases, and long-term chronic diseases such as cancer. Several reports have revealed the direct association between exposure to the poor air quality and increasing rate of morbidity and mortality mostly due to cardiovascular and respiratory diseases. Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer's and Parkinson's diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight. In this review article, we aimed to discuss toxicology of major air pollutants, sources of emission, and their impact on human health.

Air Pollution: Everything You Need to Know

Atmospheric pollution is not the only type of contamination that is harming living beings on the planet. And according to the European Environment Agency EEA , noise is responsible for 16, premature deaths and more than 72, hospitalisations every year in Europe alone. According to the WHO, noise is harmful when it exceeds 75 decibels dB and feels painful at levels above dB. Drivers honking the horn, groups of workers drilling the road surface, aircraft flying over us in the sky Noise, noise and more noise.

Jump to navigation. Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole. The Clean Air Act authorizes the U. Environmental Protection Agency EPA to protect public health by regulating the emissions of these harmful air pollutants. The NRDC has been a leading authority on this law since it was established in These two are the most prevalent types of air pollution.


Causes of Air Pollution​​ The combustion of fossil fuels emits a large amount of sulphur dioxide. Carbon monoxide released by incomplete combustion of fossil fuels also results in air pollution.


NOISE POLLUTION

The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise. The particulate forms are: PM10 and PM2. Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminum.

One of the biggest problems concerning our daily lives is what we breathe and is it good for our lungs. Our air is filled with dangerous airborne particles that can cause many respiratory diseases. Air pollution can be caused naturally as well as man-made. This is one powerful force that can kill an entire civilization gradually and the worst part is that it affects the entire environment and the surrounding areas around it. Air pollution can be caused naturally by fine particles emitted out of coal and wood and this can pollute the air surrounding you.

Сьюзан, ослепленная темнотой шифровалки, спускалась, не отрывая руки от плеча Стратмора. Даже в полуметре от шефа она не видела очертаний его фигуры. Всякий раз, ступая на очередную ступеньку, она носком туфли первым делом старалась нащупать ее край. К ней снова вернулись страхи, связанные с новой попыткой найти ключ Хейла в Третьем узле.

 Верно.

 Я серьезно. Рано или поздно я отсюда смоюсь. - Я этого не переживу.

    Air pollution occurs when gases, dust particles, fumes (or smoke) or odour are introduced into the atmosphere in a way that makes it harmful to humans, animals and plant. It creates smog and acid rain, causes cancer and respiratory diseases, reduces the ozone layer atmosphere and contributes to global warming.

    One of our era's greatest scourges is air pollution, on account not only of its impact on climate change but also its impact on public and individual health due to increasing morbidity and mortality.
