“…Two PPCPs were involved in this experiment, namely acetaminophen (Middle East Laboratories Co. Ltd, Iraq) and methylparaben (VWR Chemicals, UK). The properties of the relevant PPCPs are summarized in Table 1 [15]. Stock solutions of each acetaminophen and methylparaben at 500 mg/L were prepared in methanol and stored before use.…”

The study aims to select suitable ornamental plant species that can survive relatively with high concentrations of acetaminophen and methylparaben in constructed wetlands. Alternanthera spp, Asparagus aethiopicus and Chlorophytum comosum are examined to withstand three initial concentrations, 20, 100 and 200 mg/L of acetaminophen and methylparaben. A total of 21 plastic pails with each 3 L capacity consisting of nine pails are used for each pharmaceutical and personal care products (PPCPs) compounds (acetaminophen and methylparaben) for three ornamental plants (Alternanthera spp, Asparagus aethiopicus and Chlorophytum comosum), with three pails as plant controls. The results reveales that both Alternanthera spp and Chlorophytum comosum exhibite a good tolerance for acetaminophen with a reduction in the total chlorophyll content of about 4.4–12.3% and 3.9–31.9% for Alternanthera spp and Chlorophytum comosum, respectively. Moreover, it is evident that high concentrations (100 and 200 mg/L) of methylparaben adversely affects the chlorophyll content of the three involved plant species. These results indicate that ornamental plants play an important role in the phytoremediation of PPCPs and can be considered as an esthetic treatment for hospital wastewater.

“…Constructed wetland (CW) is an extremely mature wastewater treatment technology that removes pollutants from wastewater through microbial metabolism, plant physiological activity, matrix adsorption, sedimentation and filtration (Wu et al 2017 ). Due to low cost, strong decontamination and less secondary pollution, CWs have become a popular wastewater treatment method and are used on a large scale (Mohammed et al 2021 ). However, the use of CWs for sewage treatment may increase CH 4 discharge and lead to “pollution exchange”, so researchers have taken great interest in managing CWs and flooded rice fields to minimize CH 4 emissions (Pangala et al 2010 ).…”

Wetlands are an important carbon sink for greenhouse gases (GHGs), and embedding microbial fuel cell (MFC) into constructed wetland (CW) has become a new technology to control methane (CH4) emission. Rhizosphere anode CW–MFC was constructed by selecting rhizome-type wetland plants with strong hypoxia tolerance, which could provide photosynthetic organics as alternative fuel. Compared with non-planted system, CH4 emission flux and power output from the planted CW–MFC increased by approximately 0.48 ± 0.02 mg/(m2·h) and 1.07 W/m3, respectively. The CH4 emission flux of the CW–MFC operated under open-circuit condition was approximately 0.46 ± 0.02 mg/(m2·h) higher than that under closed-circuit condition. The results indicated that plants contributed to the CH4 emission from the CW–MFC, especially under open-circuit mode conditions. The CH4 emission from the CW–MFC was proportional to external resistance, and it increased by 0.67 ± 0.01 mg/(m2·h) when the external resistance was adjusted from 100 to 1000 Ω. High throughput sequencing further showed that there was a competitive relationship between electrogenic bacteria and methanogens. The flora abundance of electrogenic bacteria was high, while methanogens mainly consisted of Methanothrix, Methanobacterium and Methanolinea. The form and content of element C were analysed from solid phase, liquid phase and gas phase. It was found that a large amount of carbon source (TC = 254.70 mg/L) was consumed mostly through microbial migration and conversion, and carbon storage and GHGs emission accounted for 60.38% and 35.80%, respectively. In conclusion, carbon transformation in the CW–MFC can be properly regulated via competition of microorganisms driven by environmental factors, which provides a new direction and idea for the control of CH4 emission from wetlands.

“…(Mutar et al, 2022a;Muter et al, 2017). Pharmaceutical and personal care products are not completely removed by conventional wastewater treatment processes; therefore, biotechnology treatment needs to be applied to reach minimum concentration when disposal to water surface (Mohammed et al, 2021). Constructed wetlands (CWs) are the biotechnology to remove micropollutants via filtration, sedimentation, adsorption, and plant-bacteria interaction (Priya et al, 2021).…”

Pharmaceutical compounds have been introduced into the aquatic ecosystems in multiple ways and sources, which negatively affects the health of the environment and humans. The river near the hospital sewage disposal is host environment for drug-resistant bacteria (DRB). In this context, the aim of the research was to detect the presence of pharmaceuticals in hospital wastewater, after treatment, at river point followed by isolation of bacteria and test for resistant pharmaceutical compound. Fifteen species of bacteria isolated by angiogenic methods were identified and tested using the well diffusion test to determine the resistance of selected bacteria to ibuprofen by survival assessment. This study showed that the ibuprofen detected by GC-mass was available in all selected points at a concentration of 3 to 120 mg/L. Lecuco. mesen.cremris and Koc.rosea have a high ability to break down the ibuprofen compound. Thus, the bacteria isolated from hospital wastewater can biologically degrade ibuprofen.
