There have been some recent stories regarding benzene (a toxic chemical) found in soft drinks as well as other fruit drinks that contain ascorbic acid and benzoate preservatives. I was doing some research last night and found these links of interest. Hope that they work for those who would like further information. If they don't work, I could give some key words or try posting them separately.
