Klein, Environmental Health Perspectives, September 1999 (v. 107, n. 9) -- Exposure of cells to carcinogenic nickel compounds induces many genes that are commonly expressed in cancer cells but not in normal cells.

LeadBatt.gif (1022 bytes) Picture (30x15, 1.4Kb) "Kids Swallowing Pennies," Environmental Health Perspectives, June 1999 (v. 107, n. 6) -- Children who swallow post-1982 pennies may develop stomach ulcers if the coins become lodged in their digestive tracts. More than 21,000 children visited the emergency room in 1997 after swallowing coins. Pennies minted after 1982 are composed largely of zinc. The chemical reaction between zinc and stomach acid (hydrochloric acid) is similar to that in wet cell batteries and would likely be caustic to the stomach lining. Too much zinc can result in ulcers, anemia, and damage to the kidneys, liver, and bone marrow.
