Ja. Vanderheever et Ju. Grobbelaar, IN-VIVO CHLOROPHYLL-A FLUORESCENCE OF SELENASTRUM-CAPRICORNUTUM AS A SCREENING BIOASSAY IN TOXICITY STUDIES, Archives of environmental contamination and toxicology, 35(2), 1998, pp. 281-286
A method for the estimation of the effect of specific toxins on phytop
lankton photosynthesis tinder of toxicity) was investigated using in v
ivo chlorophyll a fluorescence. No meaningful results were obtained wi
th the following substances; copper, cadmium, mercury, and gusathion,
within a 4-h exposure period. It can, therefore, be concluded that in
vivo chlorophyll a fluorescence an not a simple bioassay tool, due to
the complexity of its origins, but a complex research tool.
