Benzene in soft drinks
Benzene in soft drinks is of potential concern due to the carcinogenic nature of the benzene molecule. This contamination is a public health concern and has caused significant outcry among environmental and health advocates. Benzene levels are regulated in drinking water nationally and internationally, and in bottled water in the United States, but only informally in soft drinks. The benzene results from decarboxylation of the preservative benzoic acid in the presence of ascorbic acid (vitamin C) and metal ions (iron and copper) that act as catalysts, especially under heat and light.
From the American Chemical Society in 1993 – Benzene production from decarboxylation of benzoic acid in the presence of ascorbic acid and a transition-metal catalyst
From 2008 Belgian study – Benzene formation from Sodium/Potassium Benzoate and Citric Acid is worsened by plastic bottle packaging
