Tim Keenan,

Thanks for sharing this info with us. I do wonder if something is missing
from that chart on exposure to those chemicals. For instance the list gives
the volumes in ratio form but where are the absolute exposure times? Could
you supply that data? Also do you know if any of the mentioned chemicals
have any build up effects in the system over time as opposed to an absolute
exposure for so and so time?

Thanks
