Poor air quality boosts risk of lung cancer, heart failure

European researchers have warned that air pollution, largely from traffic fumes significantly increases risk of developing lung cancer and heart diseases.
An international team of research observed 35 studies with data for thousands of patients in 12 countries, including some European states, the US and China.

The study of 300,000 people over a period of 13 years shows that areas where traffic increased, residents had a higher risk of developing lung cancer and heart failure, according to the paper published in the international medical journal The Lancet.

Some 2095 people from among the total participated number have been diagnosed with lung cancer.

In patients involved in heart failure, the pollution leads the heart muscle to become weak and less good at its job of pumping blood around the body. This condition is regarded as the consequence of a heart attack.

The danger highly threatens those people exposed to high levels of pollution where gases such as carbon monoxide, sulfur dioxide and other gaseous pollutants can get deep into the lungs and, from there, into the bloodstream.

According to the World Health Organization, air pollution in towns and cities kills 1.3 million people globally each year.

While nearly 30,000 people die prematurely each year as a direct result of exposure to air pollution in the UK, poor air quality has been placed among the top 10 causes of mortality in the state.
