Effects of microplastic leachate and a typical plastic additive on the early development of zebrafish embryos and the gut microbiota of adult zebrafish

The abundance and structure of the adult zebrafish intestinal flora were significantly altered by 2,4-DTBP, with the highest level of diversity occurring at low concentrations (0.01 mg/L). The abundance of beneficial bacteria was significantly reduced while the abundance of pathogens increased.
