An innovative experimental device to assess the behavior of a chemical under controlled environmental parameters

Abstract (ID 2017-381) Knowledge of the behavior of HNS (Hazardous and Noxious Substances) spilled into the aquatic environment is essential to define appropriate response actions; e.g. deployment of efficient equipment and activation of appropriate procedures. As a first approach, the Standard European Behaviour Classification (SEBC) may be used to acquire global knowledge of the short-term behavior of the chemical spilled, taking into account its basic physical and chemical properties (density, solubility and vapor pressure). However, the SEBC presents several limitations. Indeed, the competition between mass transfer processes (evaporation, dissolution, etc.) is not considered when the behavior of the chemical is theoretically determined from its physical chemical properties alone. Moreover, these measurements are made in standardized conditions (e.g. temperature of 20°C, freshwater) while, depending on its nature, the behavior of a chemical can greatly vary with temperature (e.g. palm oil may be solid...
