Toxicity of the mixture of nanoparticles to algae–bacteria consortia in OECD media

Toxicity trend of 0.1 mg L −1 NPs in consortia: CuO > ZnO > CuO + ZnO. At 0.1 mg L −1 , NP toxic effect was antagonistic and resulted in a higher decrease in bacterial count than algal count. Growth of consortia in a mixture of NPs up to 0.1 mg L −1 is possible.
