Description
Summary:A 20 hour laboratory study to determine the influence of various aluminium concentrations, in natural boglake water, on the sodium influx and haemolymph sodium concentration of adult waterbugs. Results are figured. A 50 per cent decrease in sodium influx was measured at elevated aluminium concentrations, and significantly increased haemolymph sodium concentrations observed. It is concluded that elevated aluminium concentrations in acidified waters causes a depression of the sodium influx, although short term exposure was not harmful to the haemolymph sodium concentration.
