“…Moreover, previous studies provide limited information on secondary risks of MPs/NPs in AD. For instance, MPs/NPs can act as carriers for other contaminants, including heavy metals, persistent chemicals, antibiotics, and, most importantly, antibiotic resistance genes (ARGs) . Antibiotic resistance is one of the most alarming global health challenges.…”

Microplastics (MPs)/nanoplastics (NPs) have been widely detected in wastewater treatment plants (WWTPs). They are captured mainly by sludge and unavoidably move into the anaerobic digestion (AD) process. Recent studies suggested that MPs/NPs could induce oxidative stress to the microbiome in digesters. The thermal hydrolysis process (THP) has been implemented for sludge pretreatment in many full-scale WWTPs. To date, there is limited knowledge about how THP can influence MPs/NPs-induced stress during AD. This study systematically investigated the impact of THP (80 and 160 °C) on AD of sewage sludge exposed to different levels (50–150 μg/L) of polystyrene nanoplastics (PsNPs), one of the most found MPs/NPs in WWTPs. Compared to the control, higher PsNPs levels of 100 and 150 μg/L decreased methane yields by 17.98 and 29.34%, respectively. Moreover, reactive oxygen species (ROS) levels increased by 17.18 and 34.84%. Our results demonstrated that THP counteracted the suppression of methane production imposed by such PsNPs concentrations, with decreased ROS levels. Also, THP reduced antibiotic resistance gene (ARG) propagation that can be encouraged by PsNPs, thus minimizing the ARG transmission risks of digestate biosolids. These findings suggest that THP holds a high promise to further develop as a remediation method for MPs/NPs in WWTPs.

“…MPs could also increase antibiotic resistant bacteria (ARB) growth and augment ARGs abundance (Process II, Figure 6B). MPs promoted the growth of Nitrospira and increased bacterial diversity in aerobic granular sludge system, 161 and favored the survival of bacteria in wastewater. 159 The presence of poly(vinyl alcohol) increased the type and abundance of ARGs in river water, 154 which might be related to the promotion of ARB proliferation.…”

“…For example, SMX adsorbed on PS MPs could disturb the composition of collembolan gut microbiota and induce the generation of sul2 and intI1. 165 However, the inhibition of ARGs transfer was also reported, 161 which could be attributed to the inhibition of ARB growth (Process V, Figure 6B), and ATs adsorption by large-size MPs (the sink of ATs) (Process VI, Figure 6B). The above processes could jointly occur during ARGs transfer in the presence of MPs, and the specific contribution needs to be determined in the specific cases in the future studies.…”

As two major types of pollutants of emerging concerns, microplastics (MPs) and antibiotics (ATs) coexist in aquatic environments, and their interactions are a source of increasing concern. Therefore, this work examines the interaction mechanisms of MPs and ATs, and the effect of MPs on ATs bioavailability and antibiotic resistance genes (ARGs) abundance in aquatic environments. First, the mechanisms for ATs adsorption on MPs are summarized, mainly including hydrophobic, hydrogen-bonding, and electrostatic interactions. But other possible mechanisms, such as halogen bonding, CH/π interaction, cation−π interaction, and negative charge-assisted hydrogen bonds, are newly proposed to explain the observed ATs adsorption. Additionally, environmental factors (such as pH, ionic strength, dissolved organic matters, minerals, and aging conditions) affecting ATs adsorption by MPs are specifically discussed. Moreover, MPs could change the bioaccumulation and toxicity of ATs to aquatic organisms, and the related mechanisms on the joint effect are reviewed and analyzed. Furthermore, MPs can enrich ARGs from the surrounding environment, and the effect of MPs on ARGs abundance is evaluated. Finally, research challenges and perspectives for MPs−ATs interactions and related environmental implications are presented. This review will facilitate a better understanding of the environmental fate and risk of both MPs and ATs.

“…Although WWTPs were found to remove microplastics efficiently, they are still primary sources for microplastics entering terrestrial and aquatic ecosystems (Raju et al, 2018;Zhang and Chen, 2020), especially for sludge (Rolsky et al, 2020;Sun et al, 2019). It should be noted that the residue microplastics also caused changes of ARG propagation in sewage in an aerobic granular sludge system (Dai et al, 2020), the leachate solution (Shi et al, 2020), and the river water receiving treated wastewater (Eckert et al, 2018).…”
