Polycyclic aromatic hydrocarbons (PAHs) are one of the most common groups pollutants that have toxic and carcinogenic effects. Black alder trees (Alnus glutinosa L.) been used to remediate contaminated soils from industrial heavy metals; however, their usefulness for PAH remediation is unclear. In this study, we examined response seedlings four half-sib families (genetic sharing same mother but different fathers) exposure PAHs-phenanthrene, pyrene, naphthalene, fluoranthene-each at three concentrations. Plant growth parameters were evaluated, concentration secondary metabolites antioxidant activity measured. The results morphological showed in general, higher concentrations had a more negative effect on tree vitality than lower (shoot reduction by up 76%). Each family also exhibited distinct responses total phenol content (TPC) when exposed varying pollutants, with reductions TPC ranging 4 52% across genetic lineages. Enzyme varied between families, concentrations; example, while phenanthrene generally increased glutathione S-transferase (GST) 13-99-1K 38-61-7K it unexpectedly decreased GST levels 23% 29% 26-133-6K 41-65-7K respectively, emphasizing nuanced divergent enzymatic observed study. Further metabolite analysis revealed variations way PAHs impact defense mechanism groups-prioritizing either or non-enzymatic systems. To sum up, analyzing effects alders can prove advantageous identifying efficient black phytoremediation purposes.

The purpose of this paper is to determine the level polycyclic aromatic hydrocarbons (PAHs) from medicinal plants and infusions prepared using them, as well assess transfer these contaminants infusions. separation compounds was achieved microwave extraction for dried liquid–liquid in case extracts were cleaned solid-phase extraction, analysed gas chromatography coupled with mass spectrometry (GC-MS). Exposure PAHs through tea infusion consumption evaluated by calculating estimated daily intake (EDI, ng/kg.bw/day) Margin (MOE). average total content varied 277.22 ± 12.78 2466.46 203.45 µg/kg dry plants, benzo[b]fluoranthene (BbF) benzo[a]pyrene (BaP) present all samples. In herbal infusions, PAH between 612.55 46.12 ng/L 2292.2 140.24 ng/L. observation statistically checked a two-sample paired test. analysis revealed that could be split into those which significantly larger than difference not significant. rates ∑16PAHs 7.25 32.86%. MOE values confirmed consumer exposure via very low safe health.
