In the present study a toxicity evaluation (Heterocypris incongruens, OstracodToxKit FTM Test) was carried out for ten municipal sewage sludges in relation to polycyclic aromatic hydrocarbon (PAH) contents in these sludges. PAHs content in the sewage sludges was determined by a vigorous extraction method and solid phase extraction with Tenax-TA. The main aim of the evaluation was establishing whether it was possible to determine the negative influence of PAHs in the sewage sludges on H. incongruens mortality and growth inhibition using the Tenax-TA method. H. inconguens showed increased growth inhibition and mortality when exposed to all sewage sludges. Significant relationships were noted between the content of some Tenax-TA PAH fractions and the total organic carbon content, cation exchange capacity and concentration of Ca(2+) ions. The toxicity was proportional to Tenax-TA concentrations and was not governed by the total concentration found in the sewage sludge.
在本研究中，针对十种城市污水污泥，就其中多环芳烃（PAH）含量开展了一项毒性评估（采用Heterocypris incongruens，OstracodToxKit FTM测试）。通过一种强力萃取方法以及用Tenax - TA进行固相萃取来测定污水污泥中的PAHs含量。该评估的主要目的是确定是否有可能使用Tenax - TA方法来判定污水污泥中PAHs对H. incongruens死亡率和生长抑制的负面影响。当暴露于所有污水污泥时，H. inconguens表现出更高的生长抑制和死亡率。在某些Tenax - TA PAH组分的含量与总有机碳含量、阳离子交换容量以及Ca(2+)离子浓度之间发现了显著关系。毒性与Tenax - TA浓度成正比，且不受污水污泥中所发现的总浓度的支配。
