Public
consultation on the SCCP/SCHER/SCENIHR preliminary report on the
"Use of the Threshold of Toxicological Concern (TTC) Approach
for the Safety Assessment of Chemical Substances"

assessment tool that is based on the principle of establishing a
human exposure threshold value for chemicals, below which there
is a very low probability of adverse effects to human health.
According to this approach, a safe level of exposure can be
identified for many chemicals based on their chemical structure
and the known toxicity of chemicals which share similar
structural characteristics.
