Abstract
M.Sc. (Botany)
Eight sampling points were selected on the Jukskei River so that
the impact of inflows from various localities on the quality of
the river water could be determined. Samples were taken every two
weeks from the 4th April 1983 to 19th March 1984. The
temperature, conductivity, dissolved oxygen and pH of the water
were determined on site. Determinations of total phosphorus (as
p-po1-), nitrate (NO), chloride (C11 and chlorophyll a were
done. After filtration the water of each sample was inoculated
with Euglena gracilis and incubated for four days under
controlled conditions after which the Euglena chlorophyll-content, primary productivity and biological growth potential
were measured...
