Carcinogenicity
Administrative data
Description of key information
The substance benzol forerunnings (coal) contains > 0.1% Benzene and can also contain > 0.1% 1,3 -butadiene. Benzene and 1,3 -butadiene are known carcinogens.
Long term carcinogenicity studies on benzene have confirmed that benzene is a carcinogen producing different types of tumours in animals (including lymphomas and leukemia). Epidimiologiocal studies on Benzene also found evidence for a causal relationship between benzene exposure and leukaemia. Due to the significant presence of benzene in benzol forerunnings (coal) the substance as a whole also has to be considered as a carcinogen.
1,3-butadiene has produced several type of tumors in animal studies. In addition epidimiological research has consistently found that exposure to 1,3-butadiene can result in increased cancer occurence. Therefore any substance containing >0.1% 1,3-butadiene has to be considered as a carcinogen.
Key value for chemical safety assessment
Justification for classification or non-classification
CAS 65996 -88 -5 has a harmonised classification as H350 (carc. 1B).
The carcinogenicity classification is in addition also supported by the presence of benzene and 1,3 butadiene, known cat 1A carcinogens in quantities in excess of 0.1%. Both of those substances also have a harmonised classification as carcinogen.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
