This work aims to test the feasibility of a Fontinalis antipyretica devitalized moss clone to uptake and accumulate polycyclic aromatic hydrocarbons (PAHs) from surface waters. To assess the capability of the devitalized clone to accumulate PAHs, in the laboratory, moss was placed in water and spiked with increasing concentrations of 16 PAHs, and under field conditions, the moss was transplanted to 22 sites of Galicia (Spain) rivers. In general, PAH concentrations in water samples were lower than the maximum allowable concentrations from Directive 2013/39/EU, so the sampling sites did not show water PAH contamination. The exponential accumulation kinetic in the laboratory trial highlights a good capability of the devitalized moss clone to accumulate total PAHs. In field experiments, the hydrogeological conditions and the low emission sources caused low concentrations of PAHs in the water system and, consequently, in the transplants, although an enrichment can be observed for several PAHs. Overall, the devitalized clone of F. antipyretica can uptake and accumulate PAHs in water and may be useful in bioremediation strategies.
本研究旨在测试失活的凤尾藓克隆体从地表水中摄取和积累多环芳烃（PAHs）的可行性。为了评估失活克隆体积累 PAHs 的能力，在实验室中，将苔藓置于水中并加入不同浓度的 16 种 PAHs，在野外条件下，将苔藓移植到加利西亚（西班牙）的 22 个河流地点。一般来说，水样中的 PAH 浓度低于 2013/39/EU 指令允许的最大浓度，因此采样点未显示水 PAH 污染。实验室试验中的指数积累动力学突出了失活苔藓克隆体积累总 PAHs 的良好能力。在野外实验中，水文地质条件和低排放源导致水中系统和移植体中的 PAHs 浓度较低，尽管可以观察到几种 PAHs 的富集。总体而言，凤尾藓的失活克隆体可以从水中摄取和积累 PAHs，可能对生物修复策略有用。
