Heavy Metals Found in Wine
Red, White Wines Carry Dangerous Doses of Toxic Metals

Oct. 29, 2008 -- Red and white wines from most European nations carry potentially dangerous doses of at least seven heavy metals, U.K. researchers find.
A single glass of even the most contaminated wine isn't poisonous. But drinking just one glass of wine a day -- a common habit in Europe and the Americas -- might be very hazardous indeed, calculate biomolecular scientist Declan P. Naughton, PhD, and Andrea Petroczi of Kingston University, London.
Naughton calculated "target hazard quotients" (THQs) for wines from 15 countries in Europe, South America, and the Middle East. The measure was designed by the U.S. Environmental Protection Agency to determine safe levels of frequent, long- term exposure to various chemicals.
A THQ over 1 indicates a health risk. Typical wines, Naughton found, have a THQ ranging from 50 to 200 per glass. Some wines had THQs up to 300. By comparison, THQs that have raised concerns about heavy-metal contamination of seafood typically range between 1 and 5.
"I was surprised at this finding, and would be very interested if regulatory authorities and food-safety people will look at this," Naughton tells WebMD. "The wine industry should look at ways to remove these metals from wine, or to find out where the metals come from and prevent this from happening."
The metal ions that accounted for most of the contamination were vanadium, copper, and manganese. But four other metals with THQs above 1 also were found: zinc, nickel, chromium, and lead.
Some 30 other metal ions were measured in the wines, but THQs could not be calculated because safe daily levels for these metals are not known.
All of these oxidating metal ions pose potential problems. But the manganese contamination particularly worries behavioral neurotoxicologist Bernard Weiss, PhD, professor of environmental medicine at the University of Rochester, N.Y. Weiss was not involved in the Naughton study.
"From the point of view of just one of these metals in wine, manganese, I would be concerned," Weiss tells WebMD. "Any time you see numbers like they have in this study, you begin to scratch your head and wonder about the effects over a long period of ingestion: Not one glass of wine last Tuesday, but a glass a day over a lifetime."
Manganese accumulation in the brain, Weiss notes, has been linked to Parkinson's disease.
Safe Metal Levels in Wines From Italy, Brazil, Argentina
Wines from three of the 15 nations studied had safe levels of heavy metals: Italy, Brazil, and Argentina.
Based on the maximum THQs for wines from each nation, here's the list of the worst offenders:
Hungary
Slovakia
France
Austria
Spain
Germany
Portugal
Greece
Czech Republic
Jordan
Macedonia
Serbia
Hungary and Slovakia had maximum potential THQ values over 350. France, Austria, Spain, Germany, and Portugal -- nations that import large quantities of wine to the U.S. -- had maximum potential THQ values over 100.

The good news is that Beer is Low in Heavy Metals
