available data for 1,2,4-trimethylbenzene indicate the acute aquatic
toxicity ranges from 2.356 mg/L (96hr EC50 for Algae - QSAR) to 7.72
mg/L (96hr LC50 for fish - measured) and the log Kow is 3.63 (i.e. <
4.0). The substance does not meet the criteria for ready
biodegradability but degrades rapidly and is therefore considered not to
be persistent in the environment.
the harmonization of Annex 1 of Directive 67/548/EEC,
1,2,4-trimethylbenzene has been classified as N R51-53 which has been
transferred to a classification of Aquatic Chronic 2 hazard to the
environment and the hazard statement 'Toxic to aquatic life with long
lasting effects' under the GHS.
