“…Novel or enhanced treatment strategies are urgently needed to address TWCs in stormwater. Green infrastructure such as bioretention cells can remove contaminants and reduce aquatic toxicity through both abiotic and biotic processes. − Following initial abiotic sorption to soil, mulch, or amendments such as biochar, − contaminants could be biologically transformed, thereby restoring sorption capacity. Nevertheless, studies on biotransformation in bioretention are often limited to bacteria or plants, with a paucity on fungi.…”

There is increasing concern about tire wear compounds (TWCs) in surface water and stormwater as evidence grows on their toxicity and widespread detection in the environment. Because TWCs are prevalent in stormwater, there is a need to understand fate and treatment options including biotransformation in green infrastructure (e.g., bioretention). Particularly, fungal biotransformation is not well-studied in a stormwater context despite the known ability of certain fungi to remove recalcitrant contaminants. Here, we report the first study on fungal biotransformation of the TWCs acetanilide and hexamethoxymethylmelamine (HMMM). We found that the model white rot fungus, Trametes versicolor, removed 81.9% and 69.6% of acetanilide and HMMM, respectively, with no significant sorption to biomass. The bicyclic amine 1,3-diphenylguanidine was not removed. Additionally, we identified novel TWC metabolites using semi-untargeted metabolomics via high-resolution mass spectrometry. Key metabolites include multiple isomers of HMMM biotransformation products, melamine as a possible “dead-end” product of HMMM (verified with an authentic standard), and a glutamine-conjugated product of acetanilide. These metabolites have implications for environmental toxicity and treatment. Our discovery of the first fungal glutamine-conjugated product highlights the need to investigate amino acid conjugation as an important pathway in biotransformation of contaminants, with implications in other fields including natural products discovery.

“…In addition to wastewater, reclamation and reuse of stormwater is considered as an important strategy in urban areas to reduce freshwater demand (Tao et al, 2017;Mark and Henriette, 2021). The stormwater characteristics (types of pollutants and their concentrations) vary depending on the types of landscapes/impervious surfaces in which rainwater flows (Song et al, 2019;Biswal et al, 2022). Rainfall characteristics such as rainfall intensity, duration and antecedent dry periods also affect the stormwater quality (Poudyal et al, 2021).…”

“…Kayhanian et al (2012) also reported that heavy metals are highly concentrated in smaller particles, e.g., in highway stormwater sediment, the concentration of Zn was 1,189 µg/g in sediments with size ranging from 25-38 µm, but a lower concentration of Zn (259 µg/g) was observed in larger size sediments (850-2000 µm). The typical level of TSS, TN and TP in stormwater ranges from 11-430 mg/L, 0.3-2.74 mg/L and 0.16-3.52 mg/L, respectively (Biswal et al, 2022). Heavy metals (Zn, Cu, and Pb) are detected between 2 and 730 µg/L, while organics (e.g., PAHs and PCBs (polychlorinated biphenyls) and microbial pollutants (e.g., fecal coliform) are usually found in very low levels (mainly ng/L) up to 10 4 CFU/ 100 ml, respectively (Biswal et al, 2022).…”

In recent years, increasing attention has been given for reclamation and reuse of water (wastewater and stormwater) in the context of augmenting water supplies. Constructed wetland (CW) systems make use of natural substrates, plants, and microbes for decontamination of wastewater and stormwater. These nature-based water treatment systems are cost-effective and sustainable. This review critically analyzes the recent advances on the application of CW systems for removal of total suspended solids (TSS), various chemical (nutrients including total nitrogen and total phosphorus, heavy metals, and organics) and microbial pollutants (Escherichia coli, enterococci, fecal coliforms, etc.) in wastewater and stormwater. Furthermore, the influence of key factors including CW configurations, substrates, vegetation, ambient temperature/seasonal changes, oxygen levels and hydraulic retention time on the performance of CW systems are discussed. Insights into various pollutant removal mechanisms, microbial diversity and modeling (kinetics, hydrological and mechanistic) are provided. CW systems show good performance for removal of diverse pollutants from wastewater and stormwater. The pollutant removal mechanisms include physical (sedimentation and filtration), chemical (sorption, complexation and precipitation) and biological (biodegradation, microbial transformation and microbial/plant assimilation) processes. The dominant microbial communities enriched in CW systems include nitrifiers, denitrifiers and organic biodegraders. The key knowledge gaps in the development of multifunctional CW systems are highlighted. We believe that this critical review would help urban planners, environmental engineers and managers with implementation of innovative strategies for wastewater and stormwater reclamation and reuse to alleviate water stress in urban areas and to contribute to environmental sustainability. Moreover, this review would help to optimize the performance of CW systems as well as to develop regulatory guidelines for installation, operation and maintenance of CW systems.

“…However, until now, no one has investigated the potential of palm kernel shell biochar (PKSB) for the removal of PAHs. Thus far, few scientific research studies are reported in the literature on the usage of PKSB for the adsorption of fluoride [30], heavy metals [31,32], crystal violet [33], and phenol [34] regarding efficient removal performance [35]. The positive outcomes of PKSB for different applications encourage investigating its potential for the removal of PAHs from PW.…”

Water pollution due to the discharge of untreated industrial effluents is a serious environmental and public health issue. The presence of organic pollutants such as polycyclic aromatic hydrocarbons (PAHs) causes worldwide concern because of their mutagenic and carcinogenic effects on aquatic life, human beings, and the environment. PAHs are pervasive atmospheric compounds that cause nervous system damage, mental retardation, cancer, and renal kidney diseases. This research presents the first usage of palm kernel shell biochar (PKSB) (obtained from agricultural waste) for PAH removal from industrial wastewater (oil and gas wastewater/produced water). A batch scale study was conducted for the remediation of PAHs and chemical oxygen demand (COD) from produced water. The influence of operating parameters such as biochar dosage, pH, and contact time was optimized and validated using a response surface methodology (RSM). Under optimized conditions, i.e., biochar dosage 2.99 g L−1, pH 4.0, and contact time 208.89 min, 93.16% of PAHs and 97.84% of COD were predicted. However, under optimized conditions of independent variables, 95.34% of PAH and 98.21% of COD removal was obtained in the laboratory. The experimental data were fitted to the empirical second-order model of a suitable degree for the maximum removal of PAHs and COD by the biochar. ANOVA analysis showed a high coefficient of determination value (R2 = 0.97) and a reasonable second-order regression prediction. Additionally, the study also showed a comparative analysis of PKSB with previously used agricultural waste biochar for PAH and COD removal. The PKSB showed significantly higher removal efficiency than other types of biochar. The study also provides analysis on the reusability of PKSB for up to four cycles using two different methods. The methods reflected a significantly good performance for PAH and COD removal for up to two cycles. Hence, the study demonstrated a successful application of PKSB as a potential sustainable adsorbent for the removal of micro-pollutants from produced water.
