Arsenic Just as Risky Ingested as Inhaled.

摘要

Lung cancer is the leading cause of death associated with arsenic exposures, exceeding mortality from bladder cancer, kidney cancer, and cardiovascular disease. Inhaled arsenic was linked to lung cancer in miners as early as 1879, and in 1980 the International Agency for Research on Cancer (IARC) determined there was sufficient evidence to identify inhaled inorganic arsenic as a human lung carcinogen. In 2004, the IARC listed arsenic in drinking water as a cause of lung cancer, making arsenic the first substance established to cause human cancer through two unrelated pathways of exposure.
