Toxicity of metal mixtures to two Antarctic marine microalgae
Progress Code: completed Statement: Data were collected in an Australian laboratory (CSIRO Land and Water, Centre for Environmental Contaminants Research, Lucas Heights, 2234, NSW) during January 2017 – April 2018. The tests used microalgal strains that had been previously collected from the Souther...
