Survival, behavior, and reproduction of Hydra viridis was studied in animals treated with the polychlorinated biphenyl mixture (PCB), Aroclor 1254. PCB was administered as a component of the culture medium (artificial pond water) in concentrations varying from 0.2 mg/l to 100.0 mg/l PCB. Reagent grade acetone was employed as a carrier for the PCB due to its low solubility in water. Control animals were maintained in a 250.0 mg/l acetone culture medium. Aroclor 1254 was lethally toxic to H. viridis with concentrations of 20.0 mg/l producing 100% mortality after a 24 hour exposure. Sublethal PCB concentrations as low as 2.0 mg/l caused lethargic behavior and decreased feeding. Reproduction was suppressed in concentrations as low as 0.2 mg/l, and morphological abnormalities occurred at PCB levels of 2.0 mg/l or greater.
