Scholarcy highlights

  • Comprehensive monitoring of water pollution is challenging
  • With the increasing amount and types of anthropogenic compounds being released into water, there are rising concerns of undetected toxicity. This is especially true for municipal wastewater effluents that are discharged to surface waters
  • Zebrafish embryos were exposed to organic extracts from the WWTP1 effluent that were reconstituted to represent 1× and 0.5× of the original concentration
  • The expression of several targeted genes were significantly affected by the wastewater treatment plants effluents and some of the downstream receiving waters
  • This integrated approach using zebrafish can supplement analytical chemistry to provide more comprehensive monitoring of discharged effluents and their receiving waters
