In relation to EM human health effects, most scientific information obtained
from cellular and animal studies provides the foundation for assessing potential risks
to humans. Studies in humans provide direct information regarding health effects
and help validate animal studies. Epidemiological studies are more likely to provide
information regarding the nature of the effect rather than provide detailed exposure response or dose-response information. When extrapolating data from animals to
develop exposure limits for humans, adjustments are usually needed to account for
several potential limitations in the process
