We actualize the WHC classifications for our substance data pool in accordance with the listings of the German Federal Environmental Agency (UBA “Rigoletto”). In the a.m. mentioned period there were some changes of classification as well as changes of the status (e.g. the confirmation of the classification of Annex 2 VwVwS by the KBwS). In the below we name the classification changes.
