Environmental impact of brine disposal of desalination plants

This study aims to develop an improved LCIA method to be used for the evaluation of ecotoxicity impacts of brine disposal from the seawater desalination process. Oceanic brine disposal has environmental impacts that are evident in many parts of the world, however, quantification assessment studies o...
