摘要
Effects of light and temperature, the most important variables in natural environments, on the toxicity of Assam crude oil extract were examined. Illumination of oil extract increased the degree of inhibition of growth, photosynthesis, and respiration of Anabaena doliolum. Higher light intensities were more effective in inhibiting the test organism. This may result from the formation of highly toxic photooxidation products. The toxicity of oil extract also showed an increase with increase in temperature, even though it might be envisioned that elevated temperature would facilitate the loss of highly toxic volatile fractions. It is possible, therefore, that the toxic effects of petroleum might be more severe in tropical than in temperate climates.
