Substances under the Chemical Substances Control Law

Priority Assessment Chemical Substances (PACSs)

Priority Assessment Chemical Substances are substances for which it is not clear whether the substance has a risk of long-term toxicity 
for humans or flora and fauna in the human living environment, which are found to remain in the environment in considerable amounts 
or are expected to remain in such a situation, and which are found to be likely to damage humans or to damage flora and fauna 
in the human living environment; they were therefore given public notice pursuant to the Chemical Substances Control Law as chemical substances 
that are found to require priority assessment of the likelihood of the chemical substances having the above risks. 

* In case of Registration No. with some MITI numbers, one MITI number is shown on the list.
