The toxicological characterization of sediments is an essential task to monitor the quality aquatic environments. Many hazardous pollutants may accumulate in and pose a risk community. present study provides attempt integrate diagnostic whole mixture assessment workflow based on slightly modified Danio rerio embryo acute toxicity test with chemical characterization. embryos were directly exposed sieved sediment (≤ 63 μm) for 96 h. Sediment samples collected from three polluted sites (Kramfors, Sundsvall Örnsköldsvik) Gulf Bothnia (Sweden) which are characterized by long history pulp paper industry impact. Effect data supported analyses 237 organic 30 trace elements. results show that malformations neurotoxic compounds main drivers differentiation effects analyses, respectively. Specific spinal cord delayed hatching observed only Kramfors while light hyperactivity was seen after exposure Sundsvall. Our experiments demonstrate specific profiles lead effect patterns embryos. In fact, behavioral endpoints could help detect neurotoxins, observation body seems be potential tool identification site-specific as polychlorinated biphenyl (PCBs), brominated flame retardants (BFRs) several pesticides. Overall, suitability fast screening samples.
