Relevance to SWEHSC: 

Environmental Arsenic Exposure, Selenium and Sputum alpha-1 Antitrypsin

Cluster of Efforts: 

Significant decreases in alpha-1-antitrypsin were seen in induced sputum from adult populations exposed to low levels of arsenic in their drinking water (20 ppb).  Decreases in this enzyme have previously been associated with the development of chronic obstructive pulmonary disease and lung cancer.
