含油污泥及其污染水体中多环芳烃及其急性生物毒性测定
Determination of polycyclic aromatic hydrocarbons and acute biotoxicty for petroleum sludge and contaminated fresh water
摘要
Abstract
In order to control the contamination of petroleum sludge,the contents,origin and calculated total toxic equivalent (TEQ) of polycyclic aromatic hydrocarbons (PAHs) in five different petroleum sludge were experimentally studied.The acute biotoxicity of different organic extractions were determined through Vibrio riseheri.The PAHs contents and acute biotoxicity of water samples contaminated by petroleum sludge were also detected.The results showed that the PAHs concentration in different petroleum sludge ranged between 496.10 to 4 233.25 μg · g-1 and the TEQ of PAHs ranged between 8.41 μg · g-1 to 231.56 μg · g-1.The n-hexane was found to be the most suitable organic solvent for testing the acute biotoxicity of petroleum sludge.The PAHs contents ranged from 9.68 to 385.16 ng · mL-1 in polluted water samples,and the contents of BaP did not exceed the standard value except for the sample polluted by an oil tank-cleaning sludge.However,acute biotoxicity of polluted water samples were very high.The highest light inhibition rate 87.46％,was much more than the light inhibition rate of 100 mg · mL-1 Zn2+.关键词
