File Name: air water and noise pollution .zip
Pollution is the process of making land, water, air or other parts of the environment dirty and not safe or suitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn't need to be tangible. Things as simple as light, sound and temperature can be considered pollutants when introduced artificially into an environment. Toxic pollution affects more than million people worldwide, according to Pure Earth , a non-profit environmental organization.
Pollution Facts & Types of Pollution
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. Cities have become the epicentre of a type of pollution, acoustics, which, although its invisibility and the fact that coronavirus crisis reduced it until almost yearn it, is severely damaging to human beings.
So much so that the European Environment Agency estimates that noise is responsible for 72, hospital admissions and 16, premature deaths every year in Europe alone. Not only does it hurt humans, it is bad for animals, too. According to the National Park Service NPS in the United States, noise pollution has an enormous environmental impact and does serious damage to wildlife.
Experts say noise pollution can interfere with breeding cycles and rearing and is even hastening the extinction of some species. Not all sound is considered noise pollution. To be precise, noise becomes harmful when it exceeds 75 decibels dB and is painful above dB.
As a consequence, it is recommended noise levels be kept below 65 dB during the day and indicates that restful sleep is impossible with nighttime ambient noise levels in excess of 30 dB. There are many sources of noise pollution, but here are some of the main ones:. Traffic noise accounts for most polluting noise in cities.
For example, a car horn produces 90 dB and a bus produces dB. There are fewer aircraft flying over cities than there are cars on the roads, but the impact is greater: a single aircraft produces dB. Building and car park construction and road and pavement resurfacing works are very noisy. For example, a pneumatic drill produces dB.
Bars, restaurants and terraces that spill outside when the weather is good can produce more than dB. This includes noise from pubs and clubs. Noise made by animals can go unnoticed, but a howling or barking dog, for example, can produce around dB. The world's noisiest cities. As well as damaging our hearing by causing — tinnitus or deafness —, constant loud noise can damage human health in many ways, particularly in the very young and the very old.
Here are some of the main ones:. Respiratory agitation, racing pulse, high blood pressure, headaches and, in case of extremely loud, constant noise, gastritis, colitis and even heart attacks.
Noise can cause attacks of stress, fatigue, depression, anxiety and hysteria in both humans and animals.
Noise above 45 dB stops you from falling asleep or sleeping properly. Remember that according to the World Health Organization it should be no more than 30 dB. Loud noise can have latent effects on our behaviour, causing aggressive behaviour and irritability. Noise may affect people's ability to focus, which can lead to low performance over time. It is also bad for the memory, making it hard to study. Interestingly, our ears need more than 16 hours' rest to make up for two hours of exposure to dB.
International bodies like the WHO agree that awareness of noise pollution is essential to beat this invisible enemy. For example: avoid very noisy leisure activities, opt for alternatives means of transport such as bicycles or electric vehicles over taking the car, do your housework at recommended times, insulate homes with noise-absorbing materials, etc.
Educating the younger generation is also an essential aspect of environmental education. Governments can also take measures to ensure correct noise management and reduce noise pollution. For example: protecting certain areas — parts of the countryside, areas of natural interest, city parks , etc. Skip to main content. Share in Twitter. Share in Facebook.

Air traffic noise There are fewer aircraft flying over cities than there are cars on the roads, but the impact is greater: a single aircraft produces dB. Construction sites Building and car park construction and road and pavement resurfacing works are very noisy. Catering and night life Bars, restaurants and terraces that spill outside when the weather is good can produce more than dB. Animals Noise made by animals can go unnoticed, but a howling or barking dog, for example, can produce around dB.
You hear about pollution all the time. It could be the smog in your city or the trash covering your beach. There are lots of them. In simple terms, pollution is the introduction of harmful chemicals into some areas of the environment. This could be the toxic gases released from the burning of fossil fuels , or it could be the ash created by a natural volcano eruption. As you can see, pollution can have natural causes or be caused by humans.
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 World Health Organization, sound levels less than 70 dB are not damaging to living organisms, regardless of how long or consistent the exposure is. Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardous. If you work for 8 hours daily in close proximity to a busy road or highway, you are very likely exposed to traffic noise pollution around 85dB. Whether we realize we are subjected to it or not, noise pollution can be hazardous to our health in various ways. Our oceans are no longer quiet.
This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution.
As the world becomes more urbanized, the use of machine-technology increases, and levels of development become higher and more complex, human exposure to noise increases. One authority estimates that the average noise level in the American city is increasing by 1 dB annually. Despite the importance and great scale of the problem, geographers generally have ignored the field of noise pollution research, perhaps because specialized equipment is necessary to accumulate the data required for analysis.
Noise pollution , unwanted or excessive sound that can have deleterious effects on human health, wildlife, and environmental quality. Noise pollution is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities. Sound waves are vibrations of air molecules carried from a noise source to the ear.

Как это удобно. Вспомнив всю услышанную от шефа ложь, она похолодела и посмотрела на него, в глазах ее мелькнуло подозрение. - Это вы убили Танкадо. Стратмор вздрогнул и замотал головой: - Конечно. Убивать Танкадо не было необходимости. Честно говоря, я бы предпочел, чтобы он остался жив.
- Стратмор сказал, что у них все в порядке. - Он солгал. Бринкерхофф не знал, что на это ответить. - Ты утверждаешь, что Стратмор намеренно запустил в ТРАНСТЕКСТ вирус. - Нет! - отрезала .
Human Diseases Caused by Noise Pollution
Своей гладкой окружной формой она напоминала дельфина-косатку, застывшего от холода в схваченном морозом море. Это был ТРАНСТЕКСТ, компьютер, равного которому не было в мире, - шифровальная машина, засекреченная агентством. Подобно айсбергу машина скрывала девяносто процентов своей массы и мощи под поверхностью. Ее секрет был спрятан в керамических шахтах, уходивших на шесть этажей вниз; ее похожий на ракету корпус окружал лабиринт подвесных лесов и кабелей, из-под которых слышалось шипение фреоновой системы охлаждения. Генераторы внизу производили постоянный низкочастотный гул, что делало акустику в шифровалке какой-то загробной, присущей миру призраков. ТРАНСТЕКСТ, подобно всем великим технологическим достижениям, появился на свет в силу необходимости. В 1980-е годы АНБ стало свидетелем революции в сфере телекоммуникаций, которой было суждено навсегда изменить весь мир разведывательной деятельности, - имеется в виду широкая доступность Интернета, а если говорить конкретнее - появление электронной почты.
Она отвалилась вместе с содранной кожей. Чип, который он должен был припаять, упал ему на голову. - Проклятие. Телефон звонил не переставая. Джабба решил не обращать на него внимания. - Мидж, - беззвучно выдавил он, - черт тебя дери. В шифровалке все в порядке! - Телефон не унимался.
В его голове смешались мысли о кольце, о самолете Лирджет-60, который ждал его в ангаре, и, разумеется, о Сьюзан. В тот момент, когда он поравнялся с сиденьем, на котором сидела девушка, и подумал, что именно ей скажет, автобус проехал под уличным фонарем, на мгновение осветившим лицо обладателя трехцветной шевелюры. Беккер смотрел на него, охваченный ужасом. Под густым слоем краски он увидел не гладкие девичьи щеки, а густую щетину. Это был молодой человек.
