Mountaintop removal mining destroys forest ecosystems and clogs streams with often toxic mining waste. And according to a new study, it also increases a person’s risk of lung cancer.

The study, published this week in the journal Environmental Science and Technology, looks at the carcinogenic potential of the particulate matter that enters the air during mountaintop removal mining, a form of surface mining that blasts the tops of mountains away so that underground coal reserves can be accessed. The study found “new evidence” that breathing in this particulate matter over an extended period of time can lead to lung cancer, confirming previous research that has found increased cases of lung cancer in communities that live near coal mining operations in Appalachia. That research noted that smoking rates in these communities are likely also contributing to the lung cancer risk, making exposure to mining operations only one of the variables involved, but this week’s research confirms, for the first time, that dust from mining operations can drive up a person’s risk of lung cancer.

“It’s a risk factor, with other risk factors, that increases the risks of getting lung cancer,” study co-author and West Virginia University cancer researcher Yon Rojanasakul told the Charleston Gazette. “That’s what the results show.”

The researchers exposed lung cells to dust from mountaintop removal operations over a three-month period. They found that the dust had “cell-transforming and tumor-promoting effects” — it led to certain changes in the cells that promoted lung cancer development.

“As more than 60,000 cancer cases has been estimated to correlate with MTM [mountaintop removal] activities in West Virginia, this finding on the cancer promoting effect of [particulate matter] and related epidemiological data are crucial to raise public health awareness to reduce cancer risk,” the study’s authors write.

Environmentalists and some Appalachian residents have fought against mountaintop removal, which is considered to be the most destructive way to extract coal, for years. According to anti-mountaintop removal group Appalachian Voices, the practice has destroyed more than 500 mountains so far in central and southern Appalachia. Blowing up the tops of these mountains obliterates temperate forest ecosystems that are among the most biologically diverse in the world.
