PROBLEM TO BE SOLVED: To provide a sampling device and a sampling method for underwater pollutant suitable as a means for catching pollutant over a long period of time to accurately measure a small amount of various pollutants suspended or dissolved in various environment water or waste water, capable of easily and securely catching a small amount of pollutant in a large amount of water, and recovering it with a high concentration magnification ratio. SOLUTION: This sampling device or this sampling method for underwater pollutant comprises a filtering means for catching suspended substance in a water sample by filtering through a stack of particles comprising different average particle diameters, the larger, the higher they position, and an absorption means in which adsorbent is filled to catch dissolved substance in the water sample by absorption. The filtering and absorption means are connected in series, and a pump is connected with these means to allow the water sample to pass through continuously. COPYRIGHT: (C)2003,JPO
