dc.description.abstract | Exponentially growing cultures of Thalassiosira pseudonana were
exposed to different concentrations of benzene, naphthalene and decane.
The acute effects of algal growth were different for increasing concentrations
of the three compounds. Benzene either did not affect cell division
or it completely blocked it. Naphthalene reduced the growth rate
gradually. Increasing concentrations of decane caused a prolonged lag
phase. After the lag phase the growth rates were similar to those of the
control.
The acute effects on 14^C-uptake followed a similar pattern for the
three components. There was a rise in the uptake with low concentrations
of hydrocarbons, followed by a sharp fall in the uptake with rising
concentrations. The concentrations giving 50% reduction in 14^C-uptake
were: 40 mg/l benzene, 2 mg/l naphthalene and 0.016 mg/l decane.
There was a linear relationship between the concentrations of hydrocarbon
giving a 50% reduction in 14^C-uptake and the solubility of the
hydrocarbon. | en |
