New Delhi, July 10 (IANS) A study has shown that air pollution might increase the risk of meningioma, a normally noncancerous brain tumour, in addition to having an impact on the heart and lungs.
The lining of the brain and spinal cord is where a common kind of brain tumour develops. According to research published in the journal Neurology, there is a connection between air pollution and meningioma, but there is not proof that the two are caused by the same thing.
The study examined a number of air contaminants, including those that are frequently associated with transportation, like nitrogen dioxide and ultrafine particles, which are particularly prevalent in metropolitan areas.
The researchers discovered that the risk of meningioma was higher for those who were exposed to more air pollution.
According to Ulla Hvidtfeldt, a doctorate student at the Danish Cancer Institute in Copenhagen, “a number of air pollution types have been demonstrated to have detrimental effects on health, and ultrafine particles are small enough to cross the blood-brain barrier and may directly affect brain tissue.”
A study in Denmark suggests long-term exposure to traffic pollution may contribute to the development of meningioma, a brain tumor, despite no strong links between pollutants and more aggressive brain tumors.
