Abstract
For aquatic ecosystems, a specific assay to measure the toxicity caused by a suspected harmful compound inplants has been developed (OECD Guideline 221), targeting biometric endpoints in Lemna sp. To provide amore in-depth evaluation, other physiological and biochemical traits can be investigated with additional plantmaterial besides that used for biometric determination. ETPT measures in real time and in a nondestructive wayplant growth and the physiological state of the photosynthetic apparatus, providing a large number of indicesassociated with toxicity endpoints linked to plant biometrics, physiology, and biochemistry.| File | Dimensione | Formato | |
