Presence, Fate, and Behaviour of Emerging Micropollutants in the New Zealand and Antarctic Coastal Environment
Many chemicals used in everyday personal care products are today amongst the most commonly detected compounds in surface waters throughout the world. Collectively referred to as micropollutants, they include paraben preservatives, organic UV filters, alkylphenols, triclosan, and bisphenol-A. Micropo...

Many chemicals used in everyday personal care products are today amongst the most commonly detected compounds in surface waters throughout the world. Collectively referred to as micropollutants, they include paraben preservatives, organic UV filters, alkylphenols, triclosan, and bisphenol-A. Micropollutants enter the aquatic environment predominantly via wastewater discharges. To date there has been only limited assessments on their presence and impacts in coastal environments. The wastewater treatment plants in Lyttelton, Governors Bay, and Diamond Harbour were found to discharge micropollutants into Whakaraupo Harbour. Similarly, the sewage effluents of the Antarctic research stations Scott Base and McMurdo Station were found to discharge micropollutants into Erebus Bay.
