GUISE

The application of bioassays in the resolution of environmental problems; past, present and futureconclusion is that some bioassays have more severe problems than others, but a concern with all of them is that responses observed in particular systems may not be relevant in general. The possibility of developing a general theoretical infrastructure for bioassays that addresses this problem is considered.

Functional bioassays utilizing zooplankton: a comparison heavy metals. It was also commonly characterized by a hormesis response. The reproduction bioassay showed the lowest variability, illustrated a reduced range of response, and was sensitive to nutrients and heavy metals. In one study, the respiration bioassay was sensitive only to PCBs.

The paper reviews the techniques being used, and those currently under development for, the water pollution control authorities in the UK. Practical examples of applications are provided and the future value of bioassays is discussed.

招待

Zimbabwean Communities in Britaingrowth stimulation of the phytoplankton after enrichment with phosphate, however, only revealed phosphate limitation from the beginning of March and bioassays may therefore be regarded as a less sensitive method.

BILE

The scientific basis of bioassays than corrected after it occurs, the predictive value of such tests is crucial. A modest base of evidence shows that, in some cases, extrapolations from bioassays on one species to another species are reasonably accurate and, in other cases, misleading. Extrapolations from laboratory bioassays to re
