|Abstract||Environmental monitoring programs for water quality control is one of the most important issues in marine aquaculture. Commonly used monitoring systems usually record only pollutant concentrations at a specific point in time by collecting spot or bottle samples. Passive sampling, widely used to monitor air pollutants, has been gaining acceptance for monitoring organic contaminants in water. Contrary to grab sampling, passive sampling is less sensitive to accidental extreme variations of the organic pollutant concentration in natural waters and is suited to the determination of time-weighted average concentrations of the pollutants. Passive sampling is based on free flow of analyte molecules from the sampled medium to a collecting medium (liquid or solid) as a result of a difference in chemical potentials. Over the past 10 years passive sampling devices have been developed that accumulate organic micropollutants and allow detection at ambient sub ng/l concentrations. This work deals on the use of passive sampling devices for screening fish farming contaminants in seawater. A validation study of passive sampling devices as effective tools in environmental monitoring programs for fish farm cage systems is addressed by determining the capability to detect trace levels of organic contaminants and sampling rates. Two different configurations of polar organic chemical integrative samplers (POCIS) available (i.e. pharmaceuticals and pesticides) were tested in the present study for sampling of polar organic contaminants including pesticides, biocides and antibiotics. Liquid and gas chromatography coupled with mass spectra (MS) detection is used for the determination of the target compounds. Results from the deployed POCIS and a discussion of the laboratory calibration study will be presented. Finally, the application of passive and active sampling methods in a field study was conducted by monitoring of organic contaminants concentrations in two different fish farms situated in Northwestern Greece near the city of Igoumenitsa.|
