The discharge of textile wastewater (TWW) into the environment releases multiple toxic substances that pose a significant threat to aquatic life. Most studies evaluating treatment efficiency focus on removal parameters, such as chemical oxygen demand (COD), total organic carbon (TOC), dissolved (DOC), biochemical (BOD), and colour. One processes has presented high efficiencies in TWW is use biochar (BC) an adsorbing material. BC shown ability remove complex from water since it able decrease content COD, TOC, DOC. However, toxicity treated effluents not been widely studied. In this regard, essential only treatments removing matter but also their reduce WW toxicity. This research evaluates acute real with Pinus patula by using Daphnia pulex sentinel species. For purpose, D. individuals were exposed BC-treated for 48 h, mortality defined absence movement limbs antennas. It was found although P. 120 min eliminated 72.8% initial DOC under optimal conditions (pH 3 13.5 g/L dose), effluent remained toxic, inducing 85.7% 71.4% rates 100% (v/v) 50% dilutions. Despite increase survival rate due protective effect achieved constituents contained reconstituted samples, these findings emphasize necessity conducting before considering after having treated.
