2.2 Comparing Exposure Doses to Health Guidelines
Evaluating Noncancer Effects
Although health assessors evaluate all adverse health effects, the method
of evaluation for cancer-related health effects differs from the methods
used to evaluate noncancer health effects. When evaluating noncancer health
effects, health assessors use the following health guidelines.
The health assessor compares the exposure dose (the amount of the chemical
that people are actually contacting) to the minimal risk level (or another
guideline). If the exposure dose is higher than the health guideline,
the exposure is further evaluated. If the exposure dose is lower than
the health guideline, noncancer effects are unlikely to occur, but if
the chemical could cause cancer, the health assessor will evaluate the
chemical further.
