Article Abstract
Currently, micro- and nanoplastics are the most concerning pollutants, which have been confirmed to exist in every stage of drinking water treatment process. Micro- and nanoplastics in drinking water have large specific surface areas, which could adsorb inorganic matter, organic matter, and microorganisms, thereby increasing their risk to human health. The adsorption and agglomeration behavior of micro- and nanoplastics on typical pollutants is called the "colloid pump effect." Focused on the micro- and nanoplastics in drinking water, the occurrence, colloid pump effect, and toxic effect on the human body and the effect of colloid pumps on the removal of micro- and nanoplastics were summarized and described. The results revealed that micro- and nanoplastics existed widely in source water, treated water, pipe network water, and tap water. The colloid pump effect of micro- and nanoplastics promoted their agglomeration with inorganic matter, organic matter, and microorganisms, which not only intensified the toxic effect of micro- and nanoplastics but also affected the removal effect. There were different viewpoints on the effect of coagulation and sedimentation on the removal of micro- and nanoplastics, and the removal effect of sand filters was limited. The advanced treatment was an efficient process to remove micro- and nanoplastics with a particle size smaller than 5 μm. The removal rate of micro- and nanoplastics could be effectively improved by exploring the mechanism of the colloid pump effect and its initiation conditions. Finally, from the perspective of the drinking water treatment process and colloid pump effect, the control of micro- and nanoplastics in drinking water was prospected in order to provide reference for reducing the occurrence and toxicity of micro- and nanoplastics in drinking water, ensuring drinking water quality safety and human health.

Several micro- and nanoplastic particle (MNP) traits, like polymer type, size, and shape, have been shown to influence MNP toxicity. However, the direction and strength of these moderating effects are often unclear, and generalizations from single studies are challenging to establish. Meta-analyses increase generalizability and derive more accurate and precise effect size estimates by combining measurements from published studies.

Detection of micro- and nanoplastic particles at extremely low concentrations in complex matrices is a critical goal in environmental science and regulatory frameworks. Surface-enhanced Raman spectroscopy (SERS) offers unique advantages for detecting molecular species in such mixtures, relying solely on their characteristic fingerprints. However, its application for plastic particles has been constrained due to weak analyte-substrate interactions.

Modeling membrane interactions with arbitrarily shaped colloidal particles, such as environmental micro- and nanoplastics, at the cell scale remains particularly challenging, owing to the complexity of particle geometries and the need to resolve fully coupled translational and rotational dynamics. Here, we present a force-based computational framework capable of capturing dynamic interactions between deformable lipid vesicles and rigid particles of irregular shapes. Both vesicle and particle surfaces are represented using triangulated meshes, and Langevin dynamics resolves membrane deformation alongside rigid-body particle motion.

Microplastics are defined as plastic particles no larger than 5 mm, while nanoplastics are even smaller particles with dimensions less than 1000 nm. With mounting evidence of their widespread presence in human tissues and diverse ecosystems, these micro- and nanoplastics (MNPs) have collectively emerged as ubiquitous environmental contaminants. They can enter the human body through ingestion, inhalation, or dermal absorption.

The oral cavity, the gateway to the digestive system, represents a critical entrance for micro- and nanoplastics (MNPs) to enter the human body. Few studies have assessed the long-term accumulation of MNPs in the oral cavity and their potential harm to resident cells. This study investigated the presence of MNPs in human dental calculus and evaluated the cytotoxic and inflammatory effects of polyethylene (PE) on human gingival fibroblasts (HGFs).
