Contaminated land burdens the economy of many countries and must be dealt with.

Researchers have published thousands of documents studying and developing soil and sediment remediation treatments. Amongst the targeted pollutants are the polycyclic aromatic hydrocarbons (PAHs), described as a class of persistent organic compounds, potentially harmful to ecosystems and living organisms.

The present paper reviews and discusses three scientific trends that are leading current PAH-contaminated soil/sediment remediation studies and management.

First, the choice of compounds that are being studied and targeted in the scientific literature is discussed, and we suggest that the classical 16 US-EPA PAH compounds might no longer be sufficient to meet current environmental challenges.

Second, we discuss the choice of experimental material in remediation studies. Using bibliometric measures, we show the lack of PAH remediation trials based on co-contaminated or aged-contaminated material.

Finally, the systematic use of the recently validated bioavailability measurement protocol (ISO/TS 16751) in remediation trials is discussed, and we suggest it should be implemented as a tool to improve remediation processes and management strategies.

受污染的土地使许多国家的经济负担沉重，必须加以处理。

研究人员已经发表了成千上万份研究和开发土壤和沉积物修复方法的文献。在目标污染物中，多环芳烃（PAHs）被描述为一类持久性有机化合物，可能对生态系统和活生物体造成危害。

本文回顾并讨论了三项科学趋势，这些趋势正在引领当前被PAH污染的土壤/沉积物修复研究和管理。

首先，讨论了科学文献中正在研究和靶向的化合物的选择，我们建议经典的16种US-EPA PAH化合物可能不再足以应付当前的环境挑战。

其次，我们讨论了补救研究中实验材料的选择。使用文献计量学的方法，我们表明缺乏基于共同污染或陈旧污染物质的PAH修复试验。

最后，讨论了在补救试验中系统地使用最近验证的生物利用度测量规程（ISO / TS 16751），我们建议应将其作为改善补救程序和管理策略的工具来实施。
