Heavy Metals Found in Wine.
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.
