Summary p-Nitrophenol (PNP),m-nitrophenol (MNP), 2,4-dinitrophenol (DNP) and catechol were tested for their effects on algal population in a soil and on pure cultures of two algae isolated from soil. Both PNP and MNP, even at 0.5 kg ha−1 level were toxic to the soil algae; high doses effected increase in toxicity. Inhibition of algae was relatively more with PNP compared to the other two nitrophenols. Catechol treatment up to 1.0 kg ha−1 led to a significant initial enhancement of algae with a subsequent far less toxic effect. The toxicity of the phenolic compounds towardChlorella vulgaris, a green alga andNostoc linckia, a blue-green alga, decreased in the order: MNP≧PNP〉DNP〉Catechol. However, algicidal or algistatic effect of the test chemicals was fairly more againstC. vulgaris, suggesting that the eukaryotic alga is highly sensitive to such soil pollutants compared to the prokaryotic alga.
