Water and wastewater treatment plants (WWTPs) receive various types of microplastics (MPs), with fibers fragments being dominant shapes. Here we investigated the removal behavior transformation MPs (polypropylene polyethylene terephthalate fragments) in simulated water units, including activated sludge process, coagulation, sand filtration, advanced oxidation/disinfection. Sand filtration demonstrated highest average efficiency removing (98 %), followed by process (61 %) coagulation (55 which was associated their physicochemical properties (shape, size, density, surface functional groups, etc). In polymer type had a greater impact on than particle shape, while shape played more important role. When subjected to long-term operation backwashing filters, approximately 15 % initially filtered broke through media, nearly no escaping. UV-based oxidation chlorination induced leaching dissolved organic matters different molecular characteristics from fragment MPs, resulting varying levels cytotoxicity bacterial toxicity. Our study provides information for predicting fate mitigating impacts WWTPs.

Strategies for the quantification and characterization of nanoplastics in AOPs research

Chemical Engineering Journal, Год журнала: 2024, Номер 493, С. 152490 - 152490

Опубликована: Май 22, 2024

There is a growing interest in developing new targeted degradation technologies for the removal of micro- and nanoplastics (NPs) water, corresponding to increased public concerns regarding their potential negative impacts on urban water systems, consequently human life quality. Recently, Advanced Oxidation Processes (AOPs) have been proposed as promising treatment alternatives effective NPs water. However, selection appropriate analytical methods monitoring these oxidation tests remains challenge. Herein, feasibility different characterization strategies evolution upon was systematically studied using polystyrene (PS) particle sizes (D0 = 140, 252, 460, 909 nm) model plastic pollutants. To quantify Total Organic Carbon (TOC), Chemical Oxygen Demand (COD) turbidity measurements were assessed. Moreover, correlated size PS concentration by response surface. Among techniques employed characterize solid particles, transmission electronic microscopy (TEM) used evaluate morphology size. Alternatively, viability Dynamic Light Scattering (DLS), Nanoparticle Tracking Analysis (NTA) Atomic Force Microscopy (AFM) determine discussed. surface modifications explored Fourier-Transform Infrared Spectroscopy (FTIR). As proof concept, photo-Fenton investigated at ambient conditions fully characterized mentioned techniques.

Microplastic Transportation in a Typical Drinking Water Supply: From Raw Water to Household Water

Water, Год журнала: 2024, Номер 16(11), С. 1567 - 1567

Опубликована: Май 30, 2024

Microplastics in drinking water have attracted increasing global concerns due to their potential adverse impacts on human health. However, there needs be more knowledge of the occurrence and distribution microplastics systems from sources household tap water. Herein, laser direct infrared spectroscopy is used investigate a typical plant with different sources. Microplastic information further understand microplastic fates during supply, including abundance, size, shape, polymer type. Overall, abundance treated ranges 12.00 25.33 particles/L, higher than those raw (RW; 2.33–17.33 particles/L) (HW; 8.00–19.67 particles/L), which shows that are not removed RW. The main polymers these polyethylene terephthalate, polyvinyl chloride, polyethylene, polypropylene. At same time, shapes fragments fibers. Small-sized 20–100 μm account for up 76.74% 79.30% dry wet seasons, respectively. Additionally, detected RW rivers reservoirs lakes, season season. As expected, ecological risk all waters I level, lowest level. Most importantly, annual intake an adult via 5063–18,301 microplastics, less reported previous studies. These results provide valuable data supply HW promote authorities update treatment technologies future remove efficiently.

Insights into Anthropogenic Micro- and Nanoplastic Accumulation in Drinking Water Sources and Their Potential Effects on Human Health

Polymers, Год журнала: 2023, Номер 15(11), С. 2425 - 2425

Опубликована: Май 23, 2023

Anthropogenic microplastics (MPs) and nanoplastics (NPs) are ubiquitous pollutants found in aquatic, food, soil air environments. Recently, drinking water for human consumption has been considered a significant pathway ingestion of such plastic pollutants. Most the analytical methods developed detection identification MPs have established particles with sizes > 10 μm, but new approaches required to identify NPs below 1 μm. This review aims evaluate most recent information on release sources intended consumption, specifically tap commercial bottled water. The potential effects health dermal exposure, inhalation, these were examined. Emerging technologies used remove and/or from their advantages limitations also assessed. main findings showed that μm completely removed treatment plants (DWTPs). smallest NP identified using pyrolysis–gas chromatography–mass spectrometry (Pyr-GC/MS) had diameter 58 nm. Contamination MPs/NPs can occur during distribution consumers, as well when opening closing screw caps or recycled glass bottles In conclusion, this comprehensive study emphasizes importance unified approach detect water, raising awareness regulators, policymakers public about impact pollutants, which pose risk.
