In the last few years, the rising level of air pollutants, particularly the fine particular matter and to a certain extent, ozone are expected to be linked in creating a risk of developing a mouth cancer. A new research study based on this has been recently published online in the Investigative Medicine Journal. The number of mouth cancers cases and deaths have increased significantly across the globe. Some of the common factors that are increasing the risk of cancer are drinking, smoking, human papilloma virus. In addition to this, in several parts of South East Asia, the continuous chewing of betel quid, which comprises of several other ingredients also results in mouth cancer.
Furthermore, the exposure to emissions and heavy metals from the petrochemicals plants can further lead to the development of the disease, while the air pollution, particularly the PM2.5 is considered as quite harmful to the cardiovascular and respiratory health. In order to discover if the air pollutants are playing a role in the development of the mouth cancer, the team of researchers have gathered and analyzed the data from health, national cancer, insurance, and the air quality.
With this data, the team of researchers have recorded the average levels of air pollutants, including carbon monoxide, sulphur dioxide, nitrogen dioxide, nitrogen monoxide, ozone, and the different sizes of the fine particulate matter, was measured in 2009 at 66 at the air quality monitoring stations in Taiwan. In the same year, it was discovered that the diagnoses of the mouth cancer were linked to the local area reading for the air pollutants.
