Polyamide 6 microplastics as carriers led to changes in the fate of bisphenol A and dibutyl phthalate in drinking water distribution systems: The role of adsorption and interfacial partitioning
AI summary Read the abstract
Researchers investigated how polyamide 6 microplastics influence the behavior of bisphenol A and dibutyl phthalate, two common plastic additives, in drinking water distribution systems. They found that the microplastics acted as carriers that changed how these chemical contaminants adsorbed onto pipe surfaces and distributed through the water system. The study suggests that the presence of microplastics in drinking water infrastructure may alter the fate and concentration of co-occurring chemical pollutants.
Microplastics (MPs) co-exist with plastic additives and other emerging pollutants in the drinking water distribution systems (DWDSs). Due to their strong adsorption capacity, MPs may influence the occurrence of additives in DWDSs. The article investigated the occurrence of typical additives bisphenol A (BPA) and dibutyl phthalate (DBP) in DWDSs under the influence of polyamide 6 (PA6) MPs and further discussed the partitioning of BPA/DBP on PA6s, filling a research gap regarding the impact of adsorption between contaminants on their occurrence within DWDSs. In this study, adsorption experiments of BPA/DBP with PA6s and pipe scales were conducted and their interaction mechanisms were investigated. Competitive adsorption experiments of BPA/DBP were also carried out with site energy distribution theory (SEDT) calculations. The results demonstrated that PA6s might contribute to the accumulation of BPA/DBP on pipe scales. The adsorption efficiencies of BPA/DBP with both PA6s and pipe scales were 26.47 and 2.61 times higher than those with only pipe scales. It was noteworthy that BPA had a synergistic effect on the adsorption of DBP on PA6s, resulting in a 26.47 % increase in DBP adsorption. The article provides valuable insights for the compounding effect of different types of additives in water quality monitoring and evaluation.

Microplastics in drinking water distribution systems: Occurrence, environmental behavior, and human health concerns
AI summary Read the abstract
This review examines how microplastics move through drinking water distribution systems, from treatment plants all the way to household taps. Despite treatment efforts, microplastics persist in the water supply, with plastic pipes and fittings themselves contributing additional contamination. The tiny particles also serve as carriers for harmful bacteria and other pollutants, compounding the health risks of microplastic-contaminated drinking water.
Microplastics as potential bisphenol carriers: role of adsorbents, adsorbates, and environmental factors
AI summary Read the abstract
Laboratory experiments showed that four common microplastic types — polystyrene, polypropylene, polyamide, and PVC — all readily adsorb bisphenols (BPA, BPB, BPF, BPS), with polyamide showing the highest capacity. Adsorption was strongly influenced by polymer surface chemistry, bisphenol hydrophobicity, temperature, and salinity. Because bisphenols are potent endocrine disruptors, microplastics acting as their environmental carriers could amplify human and wildlife exposure through contaminated seafood and drinking water.
