Scholarcy highlights

  • The prevention of water bodies deterioration is an urgent issue nowadays
  • Regarding data reported in this paper for water samples, the unsatisfactory QCs recoveries only affected to ciprofloxacin and norfloxacin, and those values must be taken as semi-quantitative
  • This study shows that wastewater treatment plants discharges into the Mijares River are contributing to environmental concentrations that may contribute to the enrichment of resistance genes in aquatic bacterial communities
  • A comprehensive investigation has been made on the occurrence and risks of pharmaceuticals in the Mijares River
  • The impact of wastewater effluents was evidenced by a notable increase of pharmaceutical concentrations as well as in the number of compounds detected in the samples collected downstream of WWTP
  • The effect of the WWTP was observed even for small populations located along the river
  • The compounds most frequently found were acetaminophen, gabapentin, venlafaxine, valsartan, ciprofloxacin and diclofenac
