Abstract: Four species of intertidal algae, two Rhodophyta and two Phaeophyta were collected from around the sewage outfall at Point Pinos, Pacific Grove, California. The algal samples were analyzed for relative pigment content through the use of comparative spectophotometry and thin layer chromatography. The brown algae directly reflected sewage distribution and concenctrations (established in other studies), by morphological damage and by a reduction in pigment content. The red algae showed various degrees of increased pigment content in the more polluted areas. Possible answers to the increase in pigments are briefily discussed. Mention is made of the possibility of using inter-and/or-subtidal brown algal pigment content as an indicator of sewage distribution near an outfall. Some pertinent morphological and ecological observations of algae in the heavily polluted areas are noted.
