Study of the effects of nanoplastics ingestion in a freshwater fish ( Danio rerio )

Abstract

View related articles View Crossmark dataConclusions: These results suggest that QDs can induce moderate or low oxidative stress. The higher results observed in fish exposed to 10 ppb and 100 ppb of QDs can be due to QDs aggregation occurring at higher QDs concentrations, which can also affect the bioavailability of toxic ions released. Therefore, in this preliminary study, the lower concentrations of QDs seem to be more hazardous to Zebrafish.

Study of the effects of nanoplastics ingestion in a freshwater fish ( Danio rerio )

“…In brief, samples (whole fish) were homogenised in a buffer solution (PBS), centrifuged at 10,000 Â g (15 min at 4 C), transferred to 1.5 mL microtubes and stored at À80 C until further analyses. The tissues were assessed for: superoxide dismutase (SOD) determined following the method described by Sun et al [3], catalase (CAT) measured following Johansson and Borg [4], glutathione S-transferase (GST) was determined according to Habig et al [5], and total antioxidant capacity (TAC) levels were determined as described in Madeira et al [6]. The fish assays were approved by the competent national authorities (DGAV).…”
