dc.description.abstractThe responses of two marine centric diatoms, Skeletonema costatum and Thalassiosira weissflogii, exposed to three bulk chemical wastes were studied in a flow-through laboratory culture system. Five growth and viability factors, consisting of chlorophyll a and adenosine triphosphate (ATP) concentrations, uptake of H14C03-, and ratios of guanosine triphosphate (GTP) to ATP and adenylate energy charge (AEC) were measured to gauge the physiological responses of the diatoms exposed in single species culture to the wastes. In addition, two of the bulk wastes were purged with helium to remove the more volatile components, and the most basic and most acidic of the bulk wastes were neutralized to pH 8 before repeating the exposure series. Finally, two of the wastes were added to a mixed culture system of the two diatoms. The American Cyanamid wastes were more inhibitory to the growth of both species of diatom than was the DuPont waste, while the Puerto Rico effluent caused no reduction in growth or production up to 4000 ppmen_US
