Description of key information
A study shows that bromotrifluoromethane in concentration of 1 ppbv (for 18 to 45 days) causes various effects on plants. The effects differ from the results obtained with other halone. BTFM has to be considered dangerous to vegetation as it interacts with vital metabolic pathways of plants.
Key value for chemical safety assessment
Additional information
A study shows that bromotrifluoromethane in concentration of 1 ppbv (for 18 to 45 days) causes various effects on plants. The effects differ from the results obtained with other halones. The present study shows that halones, although regarded as beneficial in protecting human ressources from fire, have to be considered dangerous to vegetation as they interact with vital metabolic pathways of plants. When concentrations build up due to fire fighting or leaks, damages have to be expected. Moreover, although plants did not die under the prolonged fumigation conditions of the experiment, it has to be expected that an environment with multiple pollution will give rise to multiple stress syndromes and the exhaustion of defence reactions.
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.
