Assessment of recent sediment influence in an urban polluted subantarctic coastal ecosystem. Beagle Channel (Southern Argentina) (original) (raw)

Baseline information about the environmental status of Ushuaia and Golondrina bays was assessed through analysis of surface and bottom seawater, sediment samples, and benthic nutrient fluxes. Results revealed significant nutrient pollution influenced by urban effluents, with sediment sampling showing high levels of ammonium and phosphate that surpass off-shore sources. The study highlights the urgent need for improved municipal wastewater management to mitigate chronic pollution in the coastal ecosystems.
