In this regard, based on the existing information of the scientific literature and laboratory experiments that aim, in particular, aquatic bioassays of acute and chronic toxicity on fish, algae, crustaceans and bacteria were established the ecotoxicological criteria. Moreover, the environmental risk induced by the active substances was quantified. The acute toxicity bioassays led to the acute lethal concentration establishment (LC50 - if bioassays were conducted on fish), acute mean inhibitory concentration (CE50- if bioassays were conducted on bacteria) and immobilization (CE50 - if bioassays were performed on crustaceans and algae). Also, chronic toxicity bioassay led to the maximum permissible concentration setting in water - MATC (fish and shellfish) and chronic no observed effect concentration values - NOEC.en-USPharmaceuticalsAssessmentEcological riskAquatic organismsProject
