Effects of air pollution on human health and practical measures for prevention in Iran

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. Smog can irritate the eyes and throat and also damage the lungs—especially of people who work or exercise outside, children, and senior citizens.

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.

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

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. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These impediments influence strongly the process of photosynthesis which rate declines sharply.

Air Pollution: Causes, Effects and Solution

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.

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.

Она принялась нажимать кнопки безжизненной панели, затем, опустившись на колени, в отчаянии заколотила в дверь и тут же замерла. За дверью послышалось какое-то жужжание, словно кабина была на месте. Она снова начала нажимать кнопки и снова услышала за дверью этот же звук.

What is Air Pollution?

Сьюзан от изумления застыла с открытым ртом. Она посмотрела на часы, потом на Стратмора. - Все еще не взломан.

Нужно выключить ТРАНСТЕКСТ и бежать. Она посмотрела на светящиеся мониторы Стратмора, бросилась к его письменному столу и начала нажимать на клавиши. Отключить ТРАНСТЕКСТТеперь это нетрудная задача, поскольку она находится возле командного терминала.

На поиски вируса нужно время, которого нет ни у нее, ни у коммандера. Но, вглядываясь в строки программы и думая, какую ошибку она могла допустить, Сьюзан чувствовала, что тут что-то не. Она запускала Следопыта месяц назад, и никаких проблем не возникло. Могли сбой произойти внезапно, сам по .

    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.
