Scholarcy highlights

  • Pharmaceutical and personal care products are used extensively worldwide and their residues are frequently reported in aquatic environments
  • Antiepileptic, antimicrobial and preservative compounds were analyzed in surface water and sediment from the Kaveri, Vellar and Tamiraparani rivers, and in the Pichavaram mangrove in India by gas chromatographymass spectrometry
  • Because carbamazepine is used only in human drugs, this may reflect the relative contributions of human excretions/sewage in these rivers
  • The mean triclosan level in the Tamiraparani River was an order of magnitude greater than in the other water systems, and the concentrations at two of the sites reported here are, to our best knowledge, among the highest detected in surface waters
  • We conclude that industrial releases are likely major contributors of triclosan into this river system
  • This is the first study on antiepileptic, antimicrobial and preservatives in rivers and mangroves from India
