10 Effects Of Air Pollution On Human Health – A large study of urban pollution in 650 cities around the world confirms fears that air pollution affects human health in the short term and is directly linked to deaths in the elderly and those who suffer from everyday illnesses.

The study, conducted by an international team of 50 scientists and published in the specialist New England Journal of Medicine, gathered data from cities in 24 countries, including Mexico City, New York City, London and Madrid. The study focused on two types of environmentally suspended particles emitted primarily by vehicle exhaust: PM

The authors of the macro study linked daily increases in these particles to increases in daily mortality from all causes, as well as increases in deaths from respiratory and cardiovascular problems.

Inside Air Vs. Outside Air: Which Could Be Worse?

Facts have proven that air quality affects human health. Living in a pollution-free environment means a better quality of life, but do we really know how air pollution affects us and which parts of our bodies are damaged by each pollution particle?

Air pollution kills approximately seven million people worldwide every year. The growth and concentration of urban populations and the way we consume energy in urban areas, such as through transportation or heating and air-conditioning systems, result in large amounts of emissions that are harmful to health.

The types of air pollution we are exposed to have different effects on our physical and mental health. Many organs and body functions can be damaged, with consequences including:

Urban populations are more susceptible to the effects of air pollution, in which case people who are already sick are particularly susceptible, as are children and the elderly.

Emissions from different modes of transport, burning of fossil fuels, industrial production, forest fires, aerosol use and radiation are some of the major causes of air pollution.

Such emission sources release gases and substances that are toxic to humans, the most harmful of which are: Tropospheric ozone (O

To mitigate the negative health impacts of air pollution, the World Health Organization (WHO) and the Climate and Clean Air Coalition (CCAC), which consists of the United Nations Environment Program (UNEP) and 54 countries and other agencies, launched the Breathe Life Initiative.

The plan “aims to mobilize cities and individuals to protect our health and the planet from the effects of air pollution” and aims to halve air pollution-related deaths by 2030.

Air Pollution By Economy

Action will be local, focusing on improving transport, waste management, indoor air quality, energy supply, industry, food and agriculture. Air pollution affects everything. It is harmful to our health and affects the environment by reducing visibility and blocking sunlight, causing acid rain and harming forests, wildlife and agriculture. Greenhouse gas pollution is the cause of climate change, affecting the entire planet.

The World Health Organization estimates that seven million people die from air pollution every year. A severe smog event in London in 1952 resulted in more than 4, 000 deaths in just a few months. Ground-level ozone causes lung muscles to contract, making breathing difficult. Exposure to high concentrations of ozone can cause sore throats, coughs, lung inflammation and permanent lung damage.

Symptoms caused by short-term exposure usually resolve quickly, but long-term exposure can cause serious illness and disease in multiple body systems. Children, the elderly and people with chronic medical conditions are more susceptible to the effects of air pollution than other groups. Urban populations are also at greater risk due to the high concentration of pollution within cities. Check the current air quality in your area to determine if you should take precautions, such as reducing or avoiding outdoor activities.

Wildlife also experience many of the same negative health effects of air pollution as humans. Respiratory damage is the most common effect on animals, but neurological problems and skin irritation are also common.

Health Effects From Noise

When exposed to air pollution for long periods of time, plant and crop growth is reduced. Ozone pollution damages plants by damaging structures called stomata, which are tiny holes on the backs of leaves that allow plants to “breathe.” Some types of plants can protect themselves by temporarily closing their stomata or producing antioxidants, but other types of plants are particularly sensitive to damage. Between 1980 and 2011, the United States lost $9 billion worth of soybeans and corn due to ozone pollution. When acid rain, lead poisoning, and exposure to nitrogen oxides change the chemistry of the soil, plants are deprived of the nutrients they need to grow and survive. This affects agriculture, forests and grasslands.

Air pollution affects living things in many other ways, such as destroying the habitats, water and food sources that plants and animals rely on to survive.

Burning fossil fuels releases sulfur oxides and nitrogen oxides into the atmosphere. Acid rain forms when sulfur dioxide and nitrogen dioxide mix with water droplets in the atmosphere to form sulfuric acid and nitric acid. Winds can carry these pollutants thousands of miles until they fall to the Earth’s surface as acid rain, which damages the leaves of vegetation, increases the acidity of soil and water, and kills more than 500 people each year. Buildings and other structures are also affected by acid rain, which causes an estimated $5 billion in property damage each year. Acid rain dissolves the mortar between bricks, causes stone foundations to become unstable, and is destroying ancient buildings and statues carved from marble and limestone.

High concentrations of particulate matter pollution from all types of burning reduce the amount of sunlight reaching the surface and even change the appearance of the sky. When less sunlight is available for photosynthesis, forest growth slows and crops become less productive. Haze weather will not only reduce visibility, but also affect the weather and even climate.

The Health Effects Of Global Warming: Developing Countries Are The Most Vulnerable

In 2019, the ozone hole over Antarctica (shown in blue) was the smallest since the hole was discovered. The ozone hole has continued to shrink since the ban on CFCs, but scientists warn that full recovery remains uncertain.

The ozone hole is caused by air pollutants. Chemicals used as refrigerants, such as chlorofluorocarbons (CFCs), contain chlorine atoms. Releasing chlorine atoms into the atmosphere destroys ozone. One chlorine atom can destroy thousands of ozone molecules. The ozone layer blocks harmful ultraviolet C (UVC) and ultraviolet B (UVB) radiation from the sun, protecting us in a similar way to applying sunscreen to your skin to prevent sunburn. The ozone hole increases the amount of ultraviolet radiation that reaches the surface, putting all living things at risk. Exposure to this radiation increases the risk of skin cancer in humans, limits the growth and development of plants, slows the development of fish and amphibians, and reduces the abundance of phytoplankton in marine ecosystems. It can also cause natural and synthetic materials to break down more quickly.

Gaseous ammonia (NH3) from agriculture and nitrogen dioxide (NO2) emitted by cars, trucks and airplanes increase nitrogen levels in the soil. Plants need nitrogen to grow, but too much nitrogen can disrupt the balance of species in an ecosystem by limiting the growth of some plants and promoting the growth of others. This destruction is negatively impacting grasslands and other fragile environments around the world.

This map shows the global ammonia hotspots discovered over 14 years. Warm colors represent an increase in ammonia, while cool colors represent a decrease in ammonia.

Ambient Air Pollution And Alzheimer’s Disease: The Role Of The Composition Of Fine Particles

Greenhouse gas pollution is causing climate change. As a result, ecosystems are changing faster than plants and animals can adapt, and many species are becoming extinct. Marine ecosystems are vulnerable to ocean acidification caused by carbon dioxide released into the atmosphere dissolving in seawater. Ocean acidification makes it difficult for many marine species to grow shells and skeletons.

Melting ice caps, warming oceans and extreme weather conditions are examples of how climate change caused by greenhouse gas pollution threatens Earth’s ecosystems. In many cases, the decline of one or a few species due to air pollution can disrupt the balance of an entire ecosystem. When we think about air quality, it’s natural to think that it’s safer and healthier to stay indoors. But consider indoor air versus outdoor air: Which is likely to be worse?

According to the EPA, there is growing evidence that the air inside our buildings is more polluted than the air outside. The longer you spend indoors, the more susceptible you are to indoor air pollution. Some of these effects appear early, while others take years to appear. Just because you feel healthy now doesn’t mean you won’t experience symptoms in the future.

There are many different air filtration products on the market. The best of them all is the Air Scrubber Plus, which uses technology developed for the U.S. space program. Originally designed to prevent premature aging of plants grown by astronauts during long-duration space missions, it was later discovered that
