Toxicological assessment of binary mixtures and individually of chemical compounds used in reverse osmosis desalination on Artemia franciscana nauplii

ABSTRACT The Reverse Osmosis desalination has become a technological option to guarantee an adequate drinking water supply in zones with water scarcity. Nevertheless, the process is accompanied by potential adverse impacts on the coastal ecosystem, mainly due to chemical discharges. Taking into acco...
