Phenalen-1-one (perinaphthenone) was isolated and characterized from the water soluble fraction of a No. 2 fuel oil. Phenalen-1-one had two very different effects on the growth of microalgae. With blue-green algae there was an abrupt toxicity, independent of wavelength, at 5 ppM. With two green algae toxicity was strongly wavelength dependent. In white light (Daylight fluorescent) 250 ppB was lethal; with this same lamp screened by a sharp-cut yellow filter (530 nm), growth rate was not affected until the concentration reached 10 ppM. The growth inhibition of a diatom by phenalen-1-one was also wavelength dependent, but the concentration required was some twentyfold that for green algae.
