No key experimental study was established. Therefore, a QSAR value was generated using the standard method in the TGD (2003). This resulted in a BCF of 243 which is similar to that reported in a CITI study conducted in 1977.
No key study has been established. Data is
reported by MITI ( Chemicals Inspection and Testing Institute;
Biodegradation and Bioaccumulation Data of Existing Chemicals Based on
the CSCL Japan. Japan Chemical Industry Ecology - Toxicology and
Information Center. ISBN 4-89074-101-1 (1992) ) using a bioconcentration
test method, however the report is not available for review. A QSAR
calculation has been performed which indicates that 1,2,4
-trimethylbenzene will not meet the definitive criteria (Part C - PBT
assessment) for B (BCF >2000 l/kg) or vB ( BCF>5000 l/kg).
