Fresh water algae were subjected to different concentrations (0.03, 0.07, 0.12, 0.25 and 0.5 g x l(-1)) of aqueous extract of reference fuel oil (EPA, USA, API Oil No. 2, 38% aromatic, 1274). Significant decrease in Chlorophyll. (a) was observed as the concentration of fuel oil was increased. The EC50 value of fuel oil after 7 days was 0.29 g x l(-1). Total algal counts and growth rate decreased in response to the studied fuel oil. High diversity values in diatoms were observed in all treated aqueous cultures. High concentrations of fuel oil significantly decreased carbohydrate and protein contents of algal cells.
将淡水藻类暴露于不同浓度（0.03、0.07、0.12、0.25和0.5 g·L⁻¹）的参考燃料油（美国环境保护局，美国石油学会2号油，38%芳烃，1274）水提取物中。随着燃料油浓度的增加，叶绿素（a）含量显著下降。7天后燃料油的半数有效浓度（EC50）值为0.29 g·L⁻¹。所研究的燃料油导致藻类总数和生长速率下降。在所有处理过的水培培养物中，硅藻的多样性值都很高。高浓度的燃料油显著降低了藻类细胞的碳水化合物和蛋白质含量。
