The aims of this study were: (i) to investigate the toxicity of N-heterocyclic polyaromatic hydrocarbons (NPAHs) quinoline, acridine, phenazine, and 1,10-phenanthroline to the soil invertebrates Eisenia fetida, Enchytraeus crypticus, Folsomia candida, and Caenorhabditis elegans, (ii) to compare the toxicity of four NPAHs and the species sensitivity, and (iii) to discuss possible risks of these compounds in soils. Different toxicities were found for the tested NPAHs which might be partially explained by their structure and properties. Effect concentrations expressed as soil pore-water concentrations were related to log K(ow), which indicated narcosis as the most probable mode of toxic action. The species sensitivity decreased in the rank: springtails >enchytraeids=earthworms> nematodes. Predicted no-effect concentration (PNEC) values were calculated for all tested species giving values from 0.5 to 6.8 mg/kg. It is unlikely that there is a risk for soil organisms in natural soils where lower NPAHs concentrations are expected.
（i）研究 N-杂环多环芳烃（NPAHs）喹啉、吖啶、吩嗪和 1,10-菲咯啉对土壤无脊椎动物赤子爱胜蚓、真涡虫、大型溞和秀丽隐杆线虫的毒性，（ii）比较四种 NPAHs 的毒性和物种敏感性，（iii）讨论这些化合物在土壤中可能存在的风险。测试的 NPAHs 表现出不同的毒性，这可能部分可以用它们的结构和性质来解释。以土壤孔隙水浓度表示的效应浓度与 log K（ow）相关，表明麻醉是最可能的毒作用模式。物种敏感性按跳虫＞真涡虫=蚯蚓＞线虫的顺序降低。对所有测试物种的预测无效应浓度（PNEC）值进行了计算，得出的数值从 0.5 到 6.8mg/kg。在预期 NPAHs 浓度较低的自然土壤中，土壤生物不太可能面临风险。
