{As an aside, in recalling our lecture in class given by Dr. Gordon on respiratory toxicology, bearing in mind that beryllium is such a highly toxic material, should it's exposure levels be changed to an one hour time frame as opposed to theeight hour exposure limit enforced presently? I only bring this up due to Dr. Grodon's mention of the debate presently going I in California about changing the threshold limit values of ozone from it's present eight hour time frame to a one hour time frame. Although, the ozone has peak levels during the day and lower levels during the night and early morning prior to rush hour.}
