CANCER RISKS
FROM ARSENIC
IN DRINKING
WATER
Environmental exposures
 Cancer risks:
 Tobacco smoke
 Radon in homes
 Arsenic
Lifetime risks of dying from cancer due
to environmental exposures
 Tobacco smoke:
 Low exposure = 4/1000
 High exposure = 10/1000
 Radon in homes:
 Average exposure = 3/1000
 High exposure = 20/1000
 Arsenic in drinking water:
 U.S. estimated average = 1/1000
 U.S. water standard = 21/1000
ARSINIC
 Organic form
 Inorganic forms
 More toxic

SKIN CANCER
 First described in 1888 in patients treated
with arsenical mixtures for skin conditions
 Arsenic from water supplies and drugs is
known to cause skin cancer
 Prevalence among highly exposed males
aged >60 reached 25%
Liver cancer
 Liver Cancer
 Angiosarcoma
 Supported by a series of case reports
 Winegrowers in Germany
 Taiwan
Lung Cancer
 Ingestion:
 Water supplies
 Comparable to tobacco smoke and radon
 Inhalation:
 Smelters
Kidney and Bladder
Cancer
 There is a clear relationship
between arsenic water levels and
bladder and kidney cancer
CONCLUSION
 Results from epidemiological studies, showed
persuasive evidence that inorganic arsenic is a
cause of human cancer at several sites.
 There is strong evidence supporting a causal
relationship between ingested arsenic and cancer
of skin, liver, lung cancer.
 There is some evidence from Taiwan supporting a
causal relationship between ingested arsenic and
cancer of kidney and bladder cancer.
Is Arsenic Useful?
 Industry
 Medicine
 Leukemia (Arsenic Trioxide, Trisenox)
 Autoimmune diseases
