✦ Synopsis

Two unicellular and two filamentous cyanobacteria (blue-green algae) were exposed under conditions optimal for photoautotrophic growth t o eleven pesticides. Low concentrations (0.01 to 5 ppm) of diuron, atrazine, and paraquat inhibited growth. With MCPA, MCPP, 2,4-D, milstem and ethrel, marked inhibitory effects were achieved only a t concentrations above 100 ppm. Growth was inhibited by glyphosate, DDT, and thiram a t intermediate concentrations. I n some cases, the effective concentration of the pesticide varied considerably with the organism tested.

Li+, C s + , Rb+, and K+ inhibit the clonal growth rate of Hydra littoralis and, depending upon conditions, can be toxic to the animals. These effects are counteracted by increasing the concentration of Na+ in the environment. In contrast to its inhibitory effect, K+, when in the presence of high co
