Nov 1, 2018 · How air pollution affects our body. Particles with a diameter of 10 microns or less (≤ PM 10) can penetrate and lodge deep inside the lungs, causing irritation, inflammation and damaging the lining of the respiratory tract. Smaller, more health-damaging particles with a diameter of 2.5 microns or less (≤ PM 2.5 – 60 of them make up the ...

Poor air quality is the largest environmental risk to public health in the UK, as long-term exposure to air pollution can cause chronic conditions such as cardiovascular and respiratory diseases as well as lung cancer, leading to reduced life expectancy. This edition of Health matters focuses on the health impacts that air pollution can have across...
Air pollution has a significant effect on public health, and poor air quality is the largest environmental risk to public health in the UK. In 2010, the Environment Audit Committeeconsidered that the cost of health impacts of air pollution was likely to exceed estimates of £8 to 20 billion. Epidemiological studies have shown that long-term exposure...
1. Where pollutants go in the body and what they do
When air pollutants enter the body, they can have effects on various different organs and systems, not just the respiratory system. This includes: 1. the eyes, nose and throat 2. the lungs and respiratory system 3. the heart – heart and blood vessel diseases, including strokes and hardening of the arteries, are one of the main effects of air pollution Emerging evidence suggests that air pollution may also affect the brain and is possibly linked to dementia and cognitive decline. There is also...
2. Impact of air pollution across a person’s lifetime
Air pollution can affect everyone, and air in all areas of the UK contains some proportion of man-made air pollutants. Exposure to air pollution has various different health effects, which come about at every stage of life, from a foetus’ first weeks in the womb all the way through to old age. The health effects of air pollution are complex, and range in severity of impact. In some cases, damage can be gradual and may not become apparent for many years. The 3 main conditions associated with a...
2.1. Early childhood development: pregnancy, the developing foetus and infancy
Pregnancy and early childhood are critical times for the formation and maturation of body systems, and the time during which the most rapid changes take place. Factors that adversely affect human development, including air pollution, can have both immediate and long-lasting effects on a person’s health, and some health impacts may only emerge later in life. As well as potential effects on foetal growth, air pollution exposure is associated with low birth weight and premature birth.
Improving air quality is crucial to reduce the health impacts discussed above and, in turn, help people live longer, healthier lives. A study in 2006 found that reducing PM by 10µg/m3would extend lifespan in the UK by 5 times more than eliminating casualties on the roads, or 3 times more than eliminating passive smoking. Everyone needs to play thei...

Apr 4, 2022 · Almost the entire global population (99%) breathes air that exceeds WHO air quality limits, and threatens their health. A record number of over 6000 cities in 117 countries are now monitoring air quality, but the people living in them are still breathing unhealthy levels of fine particulate matter and nitrogen dioxide, with people in low and middle-income countries suffering the highest exposures.
Air pollution is the presence of one or more contaminants in the atmosphere, such as dust, fumes, gas, mist, odour, smoke or vapor, in quantities and duration that can be injurious to human health. The main pathway of exposure from air pollution is through the respiratory tract. Breathing in these pollutants leads to inflammation, oxidative ...
Air pollution, which kills an estimated 7 million people every year, is the biggest environmental health risk of our time. Airborne pollutants are responsible for about one third of deaths from stroke, chronic respiratory disease, and lung cancer, as well as one quarter of deaths from heart attack. Air pollution is also fundamentally altering our climate, with profound impacts on the health of ...
