They found that the wine with the highest arsenic level contained 68.4 ppb. The overall mean concentration for all wines tested was 12.5 ppb. The wines named in the suit contained a mean of 25.6 ppb compared to 7.42 ppb for the randomly purchased wines. They found that cheaper wines generally contained higher levels.
