Hydrocarbons have an utmost economical importance but may also cause substantial ecological impacts due to accidents or inadequate transportation and use. Currently, freshwater biomonitoring methods lack an indicator that can unequivocally reflect the impacts caused by hydrocarbons while being independent from effects of other stressors. The aim of the present study was to develop a sensitivity ranking for freshwater invertebrates towards hydrocarbon contaminants, which can be used in hydrocarbon-specific bioindicators. We employed the Relative Sensitivity method and developed the sensitivity ranking S based on literature ecotoxicological data supplemented with rapid and mesocosm test results. A first validation of the sensitivity ranking based on an earlier field study has been conducted and revealed the S ranking to be promising for application in sensitivity based indicators. Thus, the first results indicate that the ranking can serve as the core component of future hydrocarbon-specific and sensitivity trait based bioindicators.
碳氢化合物具有极其重要的经济意义，但由于事故或运输及使用不当，也可能造成重大的生态影响。目前，淡水生物监测方法缺乏一种能够明确反映碳氢化合物造成的影响，同时又不受其他压力源影响的指标。本研究的目的是为淡水无脊椎动物对碳氢化合物污染物的敏感性制定一个排名，可用于特定碳氢化合物的生物指标。我们采用了相对敏感性方法，并根据文献中的生态毒理学数据，辅以快速和中宇宙试验结果，制定了敏感性排名S。基于早期的实地研究对敏感性排名进行了首次验证，结果表明S排名有望应用于基于敏感性的指标。因此，初步结果表明，该排名可作为未来特定碳氢化合物和基于敏感性特征的生物指标的核心组成部分。
