“…A probable exposure time of 1 day is not practical in many cases because of inadequate catches or other limitations. However, if we consider the fast mineralization rates of phytoplankton [184,185] as well as of zooplankton [190][191][192], with a phosphorus release of >-70% within 1 day, and moreover assume mean sinking velocities of >-1 to 4 m/day in the epilimnetic layer of a lake, it is likely that a large portion of the dead cells have already lost most of their phosphorus before they reach a trap set at the lower boundary of the epilimnion. Thus only the more refractory components (partly nitrogen, organic carbon) will be collected in the hypolimnetic layers and affected by bacterial breakdown.…”

“…It is obvious that extractions according to WASHED this type of scheme cannot be expected to be both completely selective and accomplish a quantitative extraction. Other extraction schemes are less complex and exclude the separation of individual condensed phosphates and nucleic acids (Golterman, 1960;Krause, 1964b).…”

“…In field studies, however, the use of chromatographic methods is limited (e.g. Krause, 1964a). Cell phosphorus composition assayed by the extraction technique shows that in general both live and dead plankton components may contain more than l/3 of the phosphorus extractable by cold TCA (Golterman, 1960;Overbeck, 1963;Krause, 1964a;UlCn, 1978b).…”
