“…FSM is considered an insignificant aspect of environmental sanitation, and discharging FS in water bodies, lagoons, and the environment is regularly considered the normal and proper way of dealing with FS. At the same time, through the utilization of sludge in the reclamation of agricultural land or fertilizer contaminants, their metabolites and transformation products [ 98 ] are circulating in the environment [ 73 , 99 – 102 ]. These substances are toxic; hence, the possibility of causing harm to humans or the environment is rising.…”

Illicit drug abuse and addiction are universal issues requiring international cooperation and interdisciplinary and multisectoral solutions. These addictive substances are utilized for recreational purposes worldwide, including in sub-Saharan Africa. On the other hand, conventional wastewater treatment facilities such as waste stabilization ponds lack the design to remove the most recent classes of pollutants such as illicit drug abuse. As a result, effluents from these treatment schemes contaminate the entire ecosystem. Public health officials are concerned about detecting these pollutants at alarming levels in some countries, with potential undesirable effects on aquatic species and increased health hazards through exposure to contaminated waters or recycling treated or untreated effluents in agriculture. Contaminants including illicit substances enter the environment by human excreta following illegal intake, spills, or through direct dumping, such as from clandestine laboratories, when their manufacturer does not follow accepted production processes. These substances, like other pharmaceuticals, have biological activity and range from pseudopersistent to highly persistent compounds; hence, they persist in the environment while causing harm to the ecosystem. The presence of powerful pharmacological agents such as cocaine, morphine, and amphetamine in water as complex combinations can impair aquatic organisms and human health. These compounds can harm human beings and ecosystem health apart from their low environmental levels. Therefore, this article examines the presence and levels of illicit substances in ecological compartments such as wastewater, surface and ground waters in sub-Saharan Africa, and their latent impact on the ecosystem. The information on the occurrences of illicit drugs and their metabolic products in the sub-Saharan Africa environment and their contribution to pharmaceutical load is missing. In this case, it is important to research further the presence, levels, distribution, and environmental risks of exposure to human beings and the entire ecosystem.

“…In 1992, Kim and Gee published a work in "Water Environmental Research" prospecting the relevant rule of biotechnology for the treatment of hazardous wastes (Kim & Gee, 1992). Approximately 30 years later, we know that bacteria can support the sustainable implementation of a circular economy by increasing the performances of wastewater treatments for water reuse (Choudri, Al-Awadhi, Charabi, & Al-Nasiri, 2020); controlling GHG emissions by the capture and/or sequestration of CO 2 or reducing its global pressures in the atmosphere (Koh & Shaw, 2018); producing hydrogen, biomethane and different forms of bioenergy (Sheehan et al, 2018); and introducing other amazing solutions with promising applications for global sustainability (Chang, DiGiovanni, & Mei, 2019).…”

“…However, majority of parts of the world are facing worst water shortage, and it has been reported that one in every five persons has no access to safe drinking water (WHO, 2015). According to previous reports, fresh water reservoirs will lose completely in near future due to rapid increase in population, urbanization and industrialization, climate change, water pollution, global warming, and loss of renewable water reservoirs (Choudri et al, 2020;Kumar & Chopra, 2018;Li et al, 2014;Naz et al, 2016;Rehman et al, 2021). Moreover, industrial consumption of fresh water for various processing steps releases huge amount of untreated wastewater into aquatic bodies affecting both flora and fauna as well as diminishing clean water reservoirs which is an alarming situation (Ali et al, 2021;Al-Najar et al, 2022;Cabral-Pinto et al, 2020;Kurwadkar et al, 2020;Rehman et al, 2012;Sehar et al, 2020Sehar et al, , 2021Zhu et al, 2017).…”

The current study was aimed to designed laboratory scale constructed wetland (CW) for the treatment of domestic wastewater under temperature range (18-38 C) and hydraulic retention times (24 and 48 h). Besides, the soil of vegetative unit of CW was assessed using conventional culturing techniques, and 13 different bacterial species (Escherichia coli, Micrococcus, Pseudomonas, Proteus, Klebsiella, Streptococcus, Alcaligenes, Salmonella, Bacillus, Enterobacter, Staphylococcus, Shigella and Corynebacterium spp.) were determined. The pathogenic microbial load was high in influent samples, but after treatment, about 73.1-99.7% and 43.5-86.7% reduction in CFU/ml and MPN/100 ml index, respectively, were observed. Moreover, the organic loads in terms of COD, TDS, TSS, and turbidity were high in all influent samples, but after treatment, average percentage removal in different physico-chemical parameters was observed during overall treatment operations, that is, COD (59.7-65.6%), TDS (59.6-76.8%), TSS (64.9-76.7%), and turbidity (72.7-91.6%), while pH of the effluent samples was observed in the prescribed limits. It was concluded that laboratory scale CW using natural flora Paspalidium flavidum and bacterial species was efficient in the reduction of different pollution indicators and hence a best option to be modified on pilot-scale for wastewater treatment in the rural regions of Peshawar. Practitioner Points• Role of retention times on performance of CW were studied.• The commonly existing vegetation was utilized to treat domestic waste water.• Both vegetations and HRT are key ingredients in obtaining high treatment efficiency.
