30 Oct 08 High metal ion levels in many table wines - new research from Kingston University in Chemistry Central Journal

Conflicting news anyone?

The director of biomedical and pharmaceutical sciences at London’s Kingston University, Declan Naughton, , together with his colleagues Andrea Petróczi, Paul Barker, Theresa Hague and Paul Andrews, did an aggregated study of existing research papers to analyze the levels of metal contamination in wines. Most of the wines affected are the so-called common table wines. They tested red and white wines from 15 countries, and the wines with the highest Target Hazard Quotient (THQ) for metal concentration were from Hungary and Slovakia with a THQ as high as 300. A safe THQ of one is considered safe.

ICP-MS results for intact beverages in the concentration ranges of high (up to 1250 ppb); medium (up to 9 ppb); low (up to 1.5 ppb). a = above working range.

They also analysed apple juices as part of their research.
