'n Studie van die akkumulering en afbraak van sekere fosfo - organiese pestisiede deur Euglena Gracilis

M.Sc. (Zoology) / Axenic cultures of Euglena gracilis in different basal medium concentrations, to simulate eutrophic conditions, were exposed to different concentrations of Monocrotophos and Dichlorvos to determine the effect of the pesticides on the growth reaction. The effect of the pesticides on the chlorophyll a content of test organisms exposed to equivalent toxicities of pesticides was determined. The amount of pesticide accumulated and me tabolised was determined by the choline esterase method and by gaschromatography. More pesticide was found to be accumulated and metabolised by organisms in the lower concentration of basal medium.
