Additional information
To assess the acute toxicity of tripropylamine to aquatic invertebrates a study was performed with Daphnia magna in accordance with German Standard Guideline DIN 38412, L11 and following nominal test concentrations: 0, 58, 100, 180, 320, 580 mg/L. The highest concentration was also tested as neutralised solution. The mobility of the invertebrates was investigated after 3, 6, 24 and 48 hours. After an exposure time of 48 h an EC50 of 99 mg/L was determined (non-neutralised solution) (BASF AG, 1990, Rep. no. 01/89/1742). The neutralisation of the highest test item concentration (580 mg/L) led to a reduced toxicity.
Based on this result, propylamine is considered acutely harmful to aquatic organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
