Studies on the Distribution of Antibiotics in Water, Suspended Solid, Bottom Mud in Semi-enclosed Sea and Its Accumulation in Plankton

摘要

In this study, 1) persistent concentration of antibiotics in seawater,sedimentation particles and mud, 2) degradation characteristic ofantibiotics in seawater under UV irradiation, and 3) accumulation ofantibiotics in plankton cultivated in a medium containing antibioticswere investigated. 0.03-4.9ppb levels of antibiotics (oxytetracyclineand ampicillin) were observed in the seawater, 0.15-3Opgilg dry mudlevels were also observed in the bottom mud. Antibiotics stimulatedplankton growth, and were accumulated into plankton.
