Toxic effects by cadium on growth and phosphate uptake by P-deficient algae

The project is a continuation of research performed by Niels Nyholm under a sabbatical leave in 1982 to the states.
Inhibition of the ecologically relevant parameter phosphate uptake may perhaps be more sensitive than inhibition of growth, and as there is no direct relation between the growth of algae and their uptake of nutrients, phosphate
uptake must be studied in short term spiking experiments Perturbations of natural communities as a result of toxic
exposure could potentially take place with no detection possible in normal growth tests, if nutrient uptake was
inhibited at a more sensitive level than seem equally sensitive, if selected mathematically consistent and
distinguishing organism response from system (reactor) response.
