air pollution detailed

1. Where does air pollution come from .
-How much pollution we breathe depends on many factors, such as access to clean
energy for cooking and heating, time of day and weather and also air pollution can
travel long distances, sometimes on all continents with international weather.
-Air pollution is very dangerous to very creature surviving, it is believed that it
comes from five main human resourcewhich includes Agriculture, Household,
Industry, Transport and Waste and other sources.
-These resources emit out a number of substances which includes carbon
monoxide, carbon dioxide, nitrogen dioxide, nitrogen oxide, ground-level ozone,
particulate matter, sulfur dioxide, hydrocarbons and all of this are very dangerous
to human health.
Agriculture
-There are two major pollutants in agriculture: livestock, methane and ammonia,
and burning agricultural waste. Methane causes asthma and other respiratory
diseases. Methane is also more energy efficient than carbondioxide, 34 times more
energy than 100 years.
-Around twenty-four percent of the world's greenhouse gas emissions come from
agriculture, forestry and other land activities.
Household
-The main sourceof air pollution in homes is the burning of internal fossil fuels,
timber and other biomass-based fuels for cooking, heating and lighting homes.
About 3.8 million premature deaths yearly are caused by indoor air pollution, the
vast majority of them in developing countries.
Industry
-In some many various countries in the world, energy productionproves to be the
leading on air pollution. Coal burning power plants are a major contributor, while
diesel generators are a growing concern in off-grid areas. Industrial processesand
the use of solvents in the chemical and mining industries also pollute the air.
Transport

2. -The global transport sector requires a quarter of energy-related carbondioxide
emissions and this percentage is increasing. Traffic emissions are connected to
about 400,000 premature deaths. Nearly half of all traffic-related air pollution
deaths are caused by diesel emissions, while those living close to big highways are
up to 12 percent more likely to be diagnosed with dementia.
Waste
-Open waste burning and organic waste in landfills produce harmful dioxins,
furans, methane, and black carbon into the atmosphere.Overally, about 40 percent
of waste is openly burned. The problem is mainly in urbanizing regions and
developing countries. Open burning of agricultural and municipal waste is
practiced in 166 out of 193 countries.
Other sources
-Volcanoes, high winds and other natural processes are causing problems. Sand
and duststorms are a concern. Dust mites can travel thousands of miles behind
these massive winds, which can also cause catastrophic damage, causing chronic
respiratory problems.
Is air pollution mainly a localproblem or can it travel long distances
-Air pollution affects areas near its source, but because it can be carried over long
distances, air pollution in one place can also affect long distances. For example,
pollutants that become highly active (PM2.5) and ozone (O3) can travel over
hundreds or even thousands of miles, leading to local and continental impacts. Air
pollution poses a problem for law enforcement and law enforcement because
countries or regions, with little control of air pollution coming from outside their
borders
-Although there is long -term air pollution and local air pollution, the source of
distance is an important factor for local air pollution. Pain sources such as nitrogen
dioxide (NO2) and sulfur dioxide (SO2), have the closest concentration levels to
the source (transportation, energy productionand industry). In one city, the area is
the largest and most likely to producepollution, while other parts of the same city
may be cleaner.
-Atmospheric conditions, suchas wind, affect the spread of pollutants and can
vary. Strong winds allow long-distance transport, and stagnant conditions can lead

3. to pollutants. Large cities in subtropicaland tropical regions, which have very
gentle winds and hours of sunshine, experience serious pollution episodes.
Mountains around cities, inland sea breezes and other local weather conditions can
influence the spread of pollutants and influence the formation of secondary
pollution.
What is the impact of air pollution on human health?
-Air pollutants that are very concerned about human health are good parts. It has a
diameter of 2.5 micrometers or less, also known as PM2.5. These beautiful parts
are not visible to the human eye and are 40 times smaller than the width of a
person’s hair. It can do a lot of damage to the body. These parts are small enough
to penetrate our lungs, where they cause lung muscle pain and can enter the
bloodstream, affecting the bodyas well as the heart and brain. The WHO estimates
that every year PM2.5 causes 7 million premature deaths.
-Air pollution causes serious illnesses and chronic diseases. There are realistic
links between long-term airborne infections and the high risk of heart disease,
brain, chronic lung disease (COPD), lung cancer and upper airway cancer, adverse
effects of pregnancy (i.e. a small number of newborns, prematurely) to give birth
and lose weight (newborns weigh five pounds), diabetes and cataracts
-Some of the immediate health effects of air pollution include irritation of the eyes,
nose and throat, shortness of breath, coughing and an increase in the frequency of
normal conditions, such as asthma and chest pain. Age, past and other factors that
can cause illness and feel contaminated, all of which can affect a person's behavior.
-Air polluting gases can also be very dangerous. Carbonmonoxide (CO), restricts
the transfer of oxygen to the tissues and can be fatal in very high concentrations.
Sulfur dioxide (SO2) is a potent lung irritant that affects the health of people with
pre-existing respiratory diseases (asthma and COPD), especially those who live
and work near sources of SO2. Nitrogen oxides (NOx) are linked to a series of
impacts, ranging from respiratory irritation to the development of asthma and
increased mortality.
