TL;DR: Quantitative cytological and fatty acid composition was determined for the diatom Cyclotella meneghiniana Kütz to elucidate changes that may occur with respect to daily photoperiod.

TL;DR: It is suggested that the daily photoperiodic variation in lipid content of phytoplankton may be an important consideration in evaluating effects of lipohilic toxicants.

TL;DR: Changes in the relative volume of polyphosphate in all three organisms suggest that Plectonema and Scenedesmus have higher phosphate nutrient requirements than Cyclotella, and the ecological implications of metal sequestering by polyph phosphate are discussed.

TL;DR: Results suggest that at sublethal doses, lipophilic toxicants exert effects that are biphasic, that is, immediately measurable effects are observed in the cells that include increases in storage products and changes in membranous organelles.

TL;DR: It is suggested that factorial design experiments approximate the natural environment more closely, as environmental factors that may change the availability of metals may also change the physiological state of the cells, which may also either amplify or mitigate the metal effects.
