How does environmental pollution affect health?

People are still afraid of environmental pollution affecting their health. However, not everyone knows how dangerous it is.

Cardiovascular effects

Air pollution can increase the risk of heart rhythm disorders and even heart attacks. “When small carbon particles enter the lungs, they cause an inflammatory response and release chemicals into the bloodstream, narrowing arteries and causing blood clots, which increases the risk of heart attacks,” said Jon Ayres, professor of environmental and respiratory medicine at the University of Birmingham (UK).

Increased risk of cancer

The World Health Organization's International Agency for Research on Cancer has found a link between air pollution and bladder cancer. Around 10,000 people in the UK are diagnosed with bladder cancer each year, mainly due to exposure to toxins in polluted air.

“Urine is highly concentrated with toxins, and the kidneys and urinary system are affected, including the bladder, which is more exposed to polluted air than other parts of the body,” explains Nick James, professor of clinical oncology at Warwick Medical School.

Effects on the brain

According to Boldsky, pollution can affect the brain, causing cognitive decline and memory loss. According to the results of a study of 20,000 women in Chicago, those who lived in polluted areas had impaired memory and thinking skills compared to those who lived in areas with clean air.

Causes infertility in men

A 2008 study that looked at male fertility in Upper Silesia, the most polluted region in Poland, found that infertility rates were higher there than in other regions. Another study in the Czech Republic found that DNA in young men’s sperm was diluted in the winter, when air pollution from coal-fired heating was higher.

Effects on the lungs

Inhaling polluted air puts a strain on the lungs, making them more susceptible to damage. It can also aggravate symptoms in people with asthma, emphysema, and bronchitis. One study also found that asthma rates were much higher in children living near polluted areas than in other areas.
