“…Corresponding to 1.86 μg/(year·capita) if the mean outlet MP mass (2.81 μg/m 3 ) is used in equation (3) . The outcome was consistent with the findings of Kirstein et al (2021) [ 30 ] and Dronjak et al (2022) [ 53 ] (27 N/(year·capita)), who employed μFTIR down to respectively 6.6 and 20 μm. However, it was also decidedly lower (∼332 times) than the estimation provided by the μRaman analysis (1533 N/(year·capita)).…”

“…The filter was immersed in 20 mL of ethanol and exposed to 40 kHz ultrasound for 30 min before being rinsed with ethanol repeatedly. After drying in the desiccator, zinc chloride solution (1.8 g/m 3 , GR; Sinopharm Chemical Reagent Co., Ltd., China) was added to remove any impurities . The solution was then ultrasonicated for 5 min and left overnight.…”

To investigate the relation of smoking and microplastic inhalation, we conducted a prospective study combining population-based and experimental work. Bronchoalveolar lavage fluid (BALF) samples from 17 smokers and 15 nonsmokers were collected in Zhuhai City, China. We simulated an active smoking model to explore the contribution of smoking to inhaled microplastics. The characteristics of microplastics in BALF samples and cigarette smoke were determined using laser direct infrared spectroscopy. We compared the differences between smokers and nonsmokers as well as between cigarette smoke and control groups. Microplastics were identified positive in all BALF samples. Smokers had higher concentrations of total microplastics (25.86 particles/ g), polyurethane (11.34 particles/g), and silicone (1.15 particles/ g) than nonsmokers. In the cigarette smoking simulation model, higher concentrations of total microplastics (9.99 particles/L), polyurethane (4.66 particles/L), and silicone (2.78 particles/L) were present in the cigarette smoke than those in the control group. We confirmed and extended the evidence on the presence of microplastics in the lower respiratory tract. These findings also provide new evidence on the relation between cigarette smoking and microplastic inhalation.

“…The results revealed no statistically significant difference between the DWTPs (p = 0.9). In addition, a study conducted on a DWTP in Barcelona, Spain, showed that the sludge samples exhibited a mean abundance of 14,360 n/kg [37]. The research findings on eight DWTPs in the UK were alarming, as the abundance of MPs in the sludge reached an astonishing 86,000 n/g [38].…”

As an emerging contaminant, the presence of microplastics is widespread in the environment. However, current research regarding the removal of microplastics by drinking water treatment plants (DWTPs) remains insufficient. This study aims to investigate microplastics in water and sludge in four DWTPs in Zhengzhou; these DWTPs have different water sources. The results revealed that the abundance of microplastics in raw water ranged from 12.80 ± 0.80 to 25.07 ± 1.67 n/L. Overall, fibers and fragments ranging from 10 to 100 μm constituted the primary components. The proportion of white and transparent microplastics was the highest. Among the ten polymer types detected, polyvinyl chloride, polyphenylene oxide, and polyethylene terephthalate were the predominant ones in raw water; polyethylene terephthalate emerged as the prevalent polymer type in treated drinking water, with both polyethylene terephthalate and polyvinyl chloride being primarily present in sludge. The removal rate of microplastics ranged from 45.8% to 74.5%. Furthermore, the removal rates at the sedimentation tank outlet accounted for more than 50.0% of the total removal rate. The abundance of microplastics in sludge was significantly higher than that in water, indicating a concentrated environment for the persistence of microplastics. The proper disposal of sludge has emerged as one of the challenges requiring our attention.
