The concentrations of ∑₁₆ priority polycyclic aromatic hydrocarbons (PAHs) for soils, roots, and above-ground parts of reed (Phragmites australis Cav.) were determined on different monitoring plots located near the city of Kamensk-Shakhtinsky, southern Russia, where historically received industrial sewage and sludge. The total PAHs concentration in monitoring soil plots was significantly higher than those in the background site which situated at the distance of 2 km from the contamination source. Accordingly, the maximum accumulation was found for phenanthrene and chrysene among the 16 priority PAHs in most of the plant samples collected in the impact zone. The effects of PAHs’ pollution on changes of Phragmites australis Cav. cellular and subcellular organelles in the studied monitoring sites were also determined using optical and electron microscopy, respectively. The obtained data showed that increasing of PAHs contamination negatively affected the ultrastructural changes of the studied plants. Phragmites australis Cav. showed a high level of adaptation to the effect of stressors by using tissue and cell levels. In general, the detected alterations under the PAHs effect were possibly connected to changes in biochemical and histochemical parameters as a response for reactive oxygen species and as a protective response against oxidative stress. The obtained results introduce innovative findings of cellular and subcellular changes in plants exposed to ∑₁₆ priority PAHs as very persistent and toxic contaminants.

在俄罗斯南部Kamensk-Shakhtinsky市附近的不同监测点上确定了芦苇（Phragmites australis Cav。）的土壤，根和地上部分的∑ ₁₆优先多环芳烃（PAHs）浓度。收到工业污水和污泥。监测土壤样地中总的PAHs浓度显着高于背景工地，距污染源2 km。因此，在影响区收集的大多数植物样品中，在16种优先PAH中发现了菲和菲的最大积累。多环芳烃的污染对芦苇变化的影响腔 还分别使用光学和电子显微镜确定了所研究监测部位的细胞和亚细胞器。获得的数据表明，PAHs污染的增加会对所研究植物的超微结构变化产生负面影响。芦苇的Cav。通过使用组织和细胞水平显示出对应激源作用的高度适应。通常，在多环芳烃作用下检测到的变化可能与生化和组织化学参数的变化有关，作为对活性氧的响应和对氧化应激的保护性响应。获得的结果介绍了暴露于∑ _16的植物细胞和亚细胞变化的创新发现 优先考虑PAHs是非常持久和有毒的污染物。
