The extensive industrial applications of engineered nanoparticles(NPs)have caused concerns regarding their potential impact on human and environmental health. They may affect the bioavailability and ecotoxicity of other coexisting pollutants in the environment. This study was conducted to evaluate the ecotoxicity of persistent organic pollutant, 2, 2 ′, 4, 4′-tetrabromodiphenyl ether(BDE-47) in the presence of multi-walled carbon nanotubes(MWCNTs), Al2O3naoparticles(Al2O3-NPs), and Ti O2naoparticles(Ti O2-N...
