“…In terms of individual ECs, sulfamethoxazole exhibited the highest detection number with 46 data points and a mean detected concentration of 219 ng/L (Figure 1a). Notably, a recent study by Guo et al highlighted sulfamethoxazole as the most frequently detected EC in Chinese surface water, with a detection concentration of 45 ng/L [4]. Moreover, sulfamethoxazole has been detected in WWTP effluent in Germany (22.9~34.9 ng/L) [21], the United States (1640 ng/L) [22], and other countries.…”

“…They mainly consist of PHACs, EDCs, persistent organic pollutants, and microplastics [2,3], among others. Advances in science and monitoring technology have led to increased detection of ECs in aquatic ecosystems such as rivers, lakes, and groundwater [4]. Due to the limited treatment performance of traditional water treatment processes, urban sewage still contains high concentrations of ECs even after treatment, making urban wastewater discharge a significant source of ECs [5][6][7][8].…”

“…Consequently, controlling EC discharge from WWTP effluent is crucial for aquatic ecosystems and human health. While governments prioritize identifying and regulating high-risk ECs [4], specific regulatory guidance is lacking. Variation in EC detection, discharge, risk, and regional characteristics necessitates determining which ECs to regulate and to what extent in WWTP effluent discharge.…”

Effluent discharged from urban wastewater treatment plants (WWTPs) is a major source of emerging contaminants (ECs) requiring effective regulation. To this end, we collected discharge datasets of pharmaceuticals (PHACs) and endocrine-disrupting chemicals (EDCs), representing two primary categories of ECs, from Chinese WWTP effluent from 2012 to 2022 to establish an exposure database. Moreover, high-risk ECs’ long-term water quality criteria (LWQC) were derived using the species sensitivity distribution (SSD) method. A total of 140 ECs (124 PHACs and 16 EDCs) were identified, with concentrations ranging from N.D. (not detected) to 706 μg/L. Most data were concentrated in coastal regions and Gansu, with high ecological risk observed in Gansu, Hebei, Shandong, Guangdong, and Hong Kong. Using the assessment factor (AF) method, 18 high-risk ECs requiring regulation were identified. However, only three of them, namely carbamazepine, ibuprofen, and bisphenol-A, met the derivation requirements of the SSD method. The LWQC for these three ECs were determined as 96.4, 1010, and 288 ng/L, respectively. Exposure data for carbamazepine and bisphenol-A surpassed their derived LWQC, indicating a need for heightened attention to these contaminants. This study elucidates the occurrence and risks of ECs in Chinese WWTPs and provides theoretical and data foundations for EC management in urban sewage facilities.

“…Since freshwater bodies are the destination of many treated and untreated wastewater discharges, most of the studies on the presence of OMPs have been aimed at determining their concentrations in surface streams, lakes and reservoirs, estuaries and, of course, drinking water supply sources. Given the possible migration routes due to point or diffuse contamination and their presence in the biota through trophic chains, their fate and bioaccumulation have also been of interest in many studies, a relevant aspect if we consider the consumption of aquatic species by humans (Alagan et al, 2023;Guo et al, 2023). It must be considered that water contamination by OMPs is not a static phenomenon and the lists and priorities regarding the OMPs to study are affected by some important variables: climate change; demographic changes, substitution of some chemicals with less problematic ones, new evidence on the toxicology and effects of OMPs, and technological development with the emergence of new applications of chemicals (Bunke et al, 2019, Yankui et al, 2019Deere et al, 2021;Hatje et al, 2022).…”

Organic micropollutants (OMPs), also called pollutants of emerging concern in certain circumstances, encompass a large group of chemical substances of natural or anthropogenic origin that, due to their molecular characteristics, present risks to human health. These include, among other chemicals, personal care products, food additives, flame retardants, and pharmaceuticals. In the light of the literature on the subject, the presence of OMPs in the different environmental compartments is addressed: air, water and soil. Results of the determinations, by gas chromatography coupled to mass spectrometry, of the concentrations of a large group of OMPs in the atmospheric particulate matter of the city of Puebla, river water, irrigation water and groundwater from the Nexapa river basin, Puebla and in Colombian soils are presented. In these environmental matrices the concentrations were in the ppb to ppt range.

“…In the realm of water source recycling, the occurrence of trace organic pollutants in wastewater, their intricate interactions during treatment processes, and their consequential impacts on wastewater treatment and fresh water generation represent pivotal challenges [ 5 ]. As we delve into these challenges, it becomes evident that the unregulated release of novel pollutants, commonly referred to as emerging contaminants (ECs), has emerged as a pressing environmental concern [ 6 , 7 , 8 , 9 ].…”

The recalcitrant nature of emerging contaminants (ECs) in aquatic environments necessitates the development of effective strategies for their remediation, given the considerable impacts they pose on both human health and the delicate balance of the ecosystem. Semiconductor-based photocatalytic technology is recognized for its dual benefits in effectively addressing both ECs and energy-related challenges simultaneously. Among the plethora of photocatalysts, black phosphorus (BP) stands as a promising nonmetallic candidate, offering a host of advantages including its tunable direct band gap, broad-spectrum light absorption capabilities, and exceptional charge mobility. Nevertheless, pristine BP frequently underperforms, primarily due to issues related to its limited ambient stability and the rapid recombination of photogenerated electron–hole pairs. To overcome these challenges, substantial research efforts have been devoted to the creation of BP-based photocatalysts in recent years. However, there is a noticeable absence of reviews regarding the advancement of BP-based materials for the degradation of ECs in aqueous solutions. Therefore, to fill this gap, a comprehensive review is undertaken. In this review, we first present an in-depth examination of the fabrication processes for bulk BP and BP nanosheets (BPNS). The review conducts a thorough analysis and comparison of the merits and limitations inherent in each method, thereby delineating the most auspicious avenues for future research. Then, in line with the pathways followed by photogenerated electron–hole pairs at the interface, BP-based photocatalysts are systematically categorized into heterojunctions (Type I, Type II, Z-scheme, and S-scheme) and hybrids, and their photocatalytic performances against various ECs and the corresponding degradation mechanisms are comprehensively summarized. Finally, this review presents personal insights into the prospective avenues for advancing the field of BP-based photocatalysts for ECs remediation.
