| Popis: | Pollution of the marine environment has been increasing as a result of anthropogenic activities. The preservation of marine ecosystems as well as the safety of harvested seafood are nowadays a global concern. In the present study, levels of pharmaceuticals and personal care products were assessed in different environmental compartments in the near-shore marine environment of False Bay, Cape Town, South Africa. The study revealed the presence of these persistent chemical compounds in different environmental samples from this location. Diclofenac was the most dominant compound detected, with higher concentration than the other pharmaceutical compounds, as well as being present in almost all the samples from the different sites (seawater, 3.70-4.18 ng/L; sediment, 92.08-171.89 ng/g dry wt; marine invertebrates, 67.67-780.26 ng/g dry wt; seaweed, 101.50-309.11 ng/g dry wt). The accumulation of pharmaceuticals and personal care products in the different species of organisms reflects the increasing anthropogenic pressure taking place at the sampling sites along the bay, as a result of population growth, resident lifestyle as well as poorly treated sewage effluent discharge from several associated wastewater-treatment plants. The concentration of these contaminants is in the order marine biota > sediments > seawater. The contaminants pose a low acute and chronic risk to the selected trophic levels. A public awareness campaign is needed to reduce the pollution at the source, as well as wastewater discharge limits need to be more stringent. Environ Toxicol Chem 2021;00:1-21. © 2021 SETAC. |
