Scholarcy highlights

  • Pharmaceuticals in the aquatic environment have received great attentions from the general and scientific community due to their potential impacts on ecological and human health
  • We investigated the occurrence of twelve acidic pharmaceuticals and herbicides in surface waters of the Yellow River, Hai River and Liao River in north China during the wet and dry seasons and assessed the potential risks to aquatic organisms posed by these acidic compounds
  • Seven acidic compounds were detected in the rivers, including five non-steroidal anti-inflammatory drugs, and two blood lipid regulators
  • The concentrations for acidic pharmaceuticals in the Yellow River and Liao River were in most cases higher in the dry season than in the wet season, but the concentrations of acidic compounds in the Hai River were generally higher in July than in November
  • High concentrations of these detected compounds in the Yellow River, Hai River and Liao River were found more frequently at those sites located in metropolitan areas, lower reaches or river confluences
  • Diclofenac and ibuprofen were found to have medium to high risks in the three rivers based on the calculated risk quotients
