EPA's Integrated Risk Information System (IRIS) risk assessment benzene BMCL of 7.
While it seems premature to make a general recommendation regarding sample sizes for DO-based toxicology studies, 75 animals per group is adequate to obtain reproducible estimates of BMC and BMCL.
Curved black lines represent the model fit, dashed blue lines represent the BMC, and red dot and dash lines indicate the BMCL.
The two companies, with JR East, will establish a maintenance service company in Bangkok to provide BMCL
with support and services.

The REPs calculated using P coefficient, BMC, and BMCL data correlated strongly between themselves (all r-values were > 0.
TCDD], BMCL, and BMC) for 1,2,3,4,6,7,8-HpCDD, the [[beta].
First, for most congeners evaluated, we obtained six REP values, which were derived from the BMC, BMCL, and regression coefficient (P) approach for two end points, thyroid volume and serum [FT.
Using the BMDL or BMCL as the point of departure in the risk assessment of noncarcinogenic compounds rather than the BMD or BMC central estimate is generally characterized as a conservative assumption (in the health-protective sense).
