It is estimated that hundreds of thousands of lung cancer deaths annually worldwide are attributable to PM air pollution. Epidemiological evidence on outdoor air pollution and the risk of other types of cancer, such as bladder cancer or breast cancer, is more limited.
What types of diseases are caused by pollution?
Ambient air pollution accounts for an estimated 4.2 million deaths per year due to stroke, heart disease, lung cancer and chronic respiratory diseases. Around 91% of the world’s population lives in places where air quality levels exceed WHO limits.
Which gas causes cancer?
Radon is a naturally-occurring radioactive gas that can cause lung cancer.
Which of the following pollution can cause cancer in human?
“The results from the reviewed studies point in the same direction: the risk of developing lung cancer is significantly increased in people exposed to air pollution.”
Which diseases are caused by polluted water?
Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year. By 2025, half of the world’s population will be living in water-stressed areas.
Which of the following diseases are caused by lead pollutants?
Adults exposed to lead are at increased risk of developing high blood pressure and kidney damage. Exposure of pregnant women to high levels of lead can cause miscarriage, stillbirth, premature birth and low birth weight and malformations. Lead has no essential role in the human body.
Which disease is aggravated by air pollution?
Air pollution is the cause and aggravating factor of many respiratory diseases like chronic obstructive pulmonary disease (COPD) (11,12), asthma (12,13), and lung cancer (14,15).
Can high radon levels cause cancer?
Being exposed to radon for a long period of time can lead to lung cancer. Radon gas in the air breaks down into tiny radioactive elements (radon progeny) that can lodge in the lining of the lungs, where they can give off radiation. This radiation can damage lung cells and eventually lead to lung cancer.
Why does radon cause cancer?
How does indoor radon gas cause lung cancer? Radon gas gives out radiation. When we breathe it in, the radiation can cause changes to the cells in our lungs and airways. This damage can lead to cancer.
Can gases cause cancer?
Radon is a cancer-causing radioactive gas. You can’t see, smell, or taste radon. But it may be a problem in your home. Studies performed at the University of Iowa have helped show that radon is the second leading cause of lung cancer and the leading environmental cause of cancer deaths in the United States.
