It was co-authored by a marine biologist and a retired English teacher. The outcome of such health risk assessments can either be a maximum tolerable intake (exposure) level, or other guidance to indicate the level of health concern (such as the Margin of Exposure), including advice on risk management measures to prevent and control contamination, and on the analytical methods and monitoring and control activities. The world of plants is so amazing in that plants can be used for so many things and in so many ways.

While levels are generally low, higher concentrations are found in potato sprouts and bitter-tasting peel and green parts, as well as in green tomatoes. Here is just one answer to this question.
