Should this be discussed with regard to our Shanghai study or with regard to our understanding of the NCI work. Regardless, I would like to speak with you regarding the API Benzene Task Force efforts. My schedule is not great this week or early next week, but I would like to try to connect with you one way or the other sometime soon.

The NCI in their latest publication have used this and it surprised me as I would think that it would only reflect the last portion of the exposure and that ttma and SPMA would be better indicators. I know Peter quite well so I have Emailed him asking for more information and will share the response received; he will also be publishing his paper as part of the meeting proceedings. Thought you would want to be aware of this and maybe we can discuss this more fully in a future TC meeting. Michael Michael G.
