“…Consequently, elements and organic compounds which exist at or below conventional detection limits in water samples can be analyzed with relative ease on suspended and ^jn situ sediments (3,11,12). Forstner and Salomons (1.3,14) suggest that fluvial sediments can be used to indicate toxic stress in aquatic ecosystems.…”

Suitability of continuous-flow centrifugation for bulk recovery of suspended sediment for biogeochemical purposes is reviewed.Centrifuge recovery characteristics and efficiencies in a variety of rivers and for different regimes are presented.The observed distribution of organochlorine residues amongst water, aquatic plants and suspended sediments demonstrate the necessity for standardized bulk collection protocol for suspended sediment.

The relationships of diatom species to dissolved heavy metals in the streams of the Uintah Basin of Utah were studied through four seasons of 1977-1978 . Niche center gradient analysis, cluster analysis and correlation analysis were performed . Achnanthes minutissima, Cyclotella meneghiniana, Cymbella minuta, Gomphonema parvulum, Navicula secreta var . apiculata, Nitzschia frustulum, Nitzschia frustulum var . perminuta, Nitzschia frustulum var . perpusilla, Nitzschia palea, and Synedra ulna appear to be indicator species of high or low heavy metal concentrations . Several other species also showed meaningful relationships to high or low heavy metal concentrations .

Cadmium is always found in association with zinc. However, zinc is an essential micronutrient in living cells, whereas cadmium has no known useful biological function. In fact, cadmium is ranked among the most hazardous trace elements in the environment and is highly toxic to all components of aquatic communities. Cadmium in soils seems tightly held and is not readily removed by leaching, and consequently, cadmium in freshwaters is mostly connected with human activities.The concentration of Cd in natural waters is usually less than 1 pg . L-' but the values vary greatly among localities; the highest concentrations of cadmium have been observed in areas with acid mine drainage. The important mechanism of toxic action of Cd on algae and cyanobacteria is thought to be the "poisoning" of enzymes, but many other toxic actions are known. A variety of environmental factors are known to modify the toxicity of cadmium. It is very difficult to allow for all of these factors simultaneously to predict the effect that a given amount of a metal will have on a given algal population. Uptake of Cd and other heavy metals to produce an internal concentration than in the external environment appears widespread in algae and cyanobacteria.
