“…The results of this study confirm that the ability of plants used in CW to absorb PAHs is highly depending on the PAHs concentration in the media in which the plants grow and also retention time [35,36]. For examples, the total concentration of 16 PAHs varied between 32 and 42 µg/kg d.m , and the accumulation of USEPA categorized 16 PAHs, which were examined in different parts of Glyceria maxima plants, and observed that PAHs in root, leaves, and stems were 85, 143, and 92 µg/kg d.m , respectively [36]. According to Sieciechowicz et al [37], they found that the average content of 15 PAHs in the soil did not exceeded 700 µg/kg d.m , while the range in the leaves was 112-118 µg/kg d.m , which was found, on average, to be twice as high as that in stems, at 49-59 µg/kg d.m , and roots, at 65-69 µg/kg d.m .…”

“…Plants may metabolize hydrocarbons in the common metabolic destinies, as well as reactive products that may accumulate in tissues, e.g., roots. Predestination is possible if hydrocarbons are available in roots and migrate across the stem [36,38,39].…”

This study aimed to evaluate the capability of horizontal subsurface flow constructed wetlands (HSFCWs) in treating contaminated wastewater with a high concentration of polycyclic aromatic hydrocarbons (PAHs) (Phenanthrene, Pyrene, and Benzo[a]Pyrene), using two plants, namely Phragmites and Vetiver. The investigated parameters were (1) PAHs uptake by the plants, (2) PAHs removal efficiencies, (3) accumulated PAHs in the soil of CWs, (4) shoot/root concentration factor, (5) translocation factor, and (6) PAHs correlation to lipid contains in the plants. During the treatment period, the results showed that the highest concentration of Phenanthrene in the shoot and the root systems of Phragmites, was 229.3 and 192 μg/g; Pyrene was 69.1 and 59.2 µg/g; and Benzo[a]Pyrene 25.1 and 20.2 µg/g, respectively. Meanwhile, in the Vetiver shoot and root systems were Phenanthrene 87.5 and 64.1 µg/g; Pyrene 63.2 and 42.1 µg/g; and Benzo[a]Pyrene 21.3 and 27.3 µg/g, respectively. The removal rates of Phenanthrene, Pyrene, and Benzo[a]Pyrene (PAHs compounds) by the CW planted with Phragmites were found to be 83%, 71%, and 81%, respectively, while the removal rates by CW planted with Vetiver were found to be 67%, 66%, and 73%, respectively. Moreover, the removal rates by unplanted CW were found to be 62%, 58%, and 55%, respectively. The results indicated that the HSFCW planted with Phragmites has an effective pathway to remove high concentrations of PAHs.

“…In particular, most of the persistent organic pollutants (POPs) are toxic, or even mutagenesis, carcinogenesis and teratogenesis. Once the pollutants enter into the groundwater system, they will even affect the natural environment and ecosystems, as well transport to the food chain through drinking water and plant accumulation, eventually endanger the public health (Raza et al 2017;Warężak et al 2016).…”

Due to the coal resource depletion, complicated geological conditions, and policy adjustment of China coal mine industry, a large number of coal mines have been closed and abandoned. The rebound of groundwater level will cause flooding of goaf and roadways after mine closure. The hydrogeological conditions change significantly as well. The pollutants will leach out, transform and transport which lead to pollution and increase risk to the groundwater system in the mining area. This research investigated closed coal mining area in Xuzhou, Zibo, Fengfeng, Kaili, Yangquan, Doulishan, Huaibei, Jiaozuo, Jingxing, Mile, etc., to present typical cases for analyzing the featured pollutants in mine water. Eight groundwater pollution pathways were summarized in closed coal mines, including pollution infiltration from surface mining fissures; submerged water infiltration pollution; leaching pollution of surface solid waste; cross strata pollution from the diversion fissure zone in the mining roof; cross strata pollution through the mining fissures in the mining floor; cross strata pollution through the water-conducting wells; cross strata pollution of faults or collapse columns; water overflow from goaf. Three typical cases on cross strata pollution in the closed/abandoned coal mine were analyzed emphatically. Aiming at the prevention and control of groundwater pollution risk in coal mine, the technical ideas of reducing quantity and pollutant of mine water, channel blocking, extraction control, purification and utilization are put forward. Based on this idea, the main pollution prevention and control technologies are recommended, and the countermeasures for the environmental protection of groundwater in closed mine are proposed.
