Organic substances can be released from numerous sources such as feed, waste, bacteria and fish in a recirculating aquaculture system (RAS). Compounds can start accumulating in the system and affect the quality of water negatively due to the fact that the water is re-used continuously. In RAS systems, the input is water from natural sources, and it will be recycled through different treatment stations and instruments to control hygiene and dis-eases as well as biological pollution. This project analyzed feed and waste samples taken from a recirculating aquaculture system (RAS) in order to determine the presence of the target chemicals (six parabens, five parabens derivatives and antimicrobial).
The samples were collected at the Nofima Center for Recirculation in Aquaculture (NCRA) in Sunndalsøra, Norway. After that, samples were processed with numerous methods and techniques for extracting the target chemicals such as solid phase extraction (SPE) and liquid-liquid extraction (LLE). Then, the samples were analyzed by using liquid chromatog-raphy – tandem mass spectrometry (LC-MS/MS).
