- Title
Effects of Crude Oil and Aromatic Hydrocarbons on the Photosynthesis of the Diatom Nitzschia palea.
- Authors
Kusk, Kresten Ole
- Abstract
The rate of light saturated photosynthesis of Nitzschia palea was reduced by crude oil, naphthalene and benzene A decrease in the rate of photosynthesis at weak irradiance was also found with crude oil and naphthalene and high concentrations of benzene On a mg/1 basis naphthalene decreased photosynthesis to a greater extent than did crude oil and crude oil to a greater extent than did benzene, A linear proportionality was found between the decrease in light saturated photosynthesis and the concentrations of aromatic hydrocarbons. The effects on photosynthesis were generally reversible, but a concentration of 700 mg benzene/1 stopped photosynthesis completely and irreversibly.
