Exposure to microplastics (MPs) has emerged as a potential threat to chronic respiratory health. However, the association between MPs exposure and allergic rhinitis (AR) in children remains unclear. We evaluated the association between MP exposure and the prevalence of AR in children. We measured 11 types of MPs in bronchoalveolar lavage fluid (BALF) collected from 207 children aged 1–16 years using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) in 2023. Logistic regression models were employed to evaluate the association between MP concentration and prevalence of AR. Polyamide 66 (PA66), polyethylene (PE), polyvinyl chloride (PVC), and polystyrene (PS) were the predominant types detected, with median concentrations of 2.33, 0.45, 0.38, and 0.08 μg/mL in BALF, respectively. Higher concentrations of PA66 were associated with an increased prevalence of AR in all children, with odds ratios (ORs) of 3.00 (95% CI: 1.23, 7.34) after adjusting for potential confounders, indicating a statistically significant association (α < 0.05). Higher concentrations of total MP exposure (Poverall = 0.012, Pnonlinear = 0.310) and PA66 exposure (Poverall = 0.012, Pnonlinear = 0.951) were significantly associated with the prevalence of AR in children aged ≤6 years but not in those aged >6 years. Our findings suggest that exposure to MPs, particularly PA66, may be associated with a higher risk of AR in younger children. Further large-scale, community-based pediatric cohort studies are needed to elucidate the underlying mechanisms.

Few large-scale studies have systematically examined the effects of maternal exposure to fine particulate matter (PM2.5) on live birth in women undergoing in vitro fertilization (IVF). This study aimed to investigate the associations between ambient PM2.5 exposure and live birth in women treated with IVF, and determine critical periods, key failure events, and vulnerable populations affected by such exposure. We included 58,637 patients from six reproductive centers in China between 2016 and 2021. We defined six exposure windows and adopted logistic regression with random-effect models to investigate the associations between PM2.5 exposure and live birth. We further categorized live birth failure as implantation failure, biochemical pregnancy loss, and miscarriage, to determine at which stage PM2.5 exposure caused the live birth failure. Subgroup analyses were conducted by female age, ovarian response, embryo quality, and transplantation protocol. For each 10 μg/m3 increase in PM2.5 concentration during follicle growth phase, preantral-antral follicle phase, and antral-mature follicle phase, the odds ratios for live birth were 0.966 [95% confidence interval (CI): 0.938, 0.995], 0.967 (0.939, 0.996), and 0.978 (0.958, 0.998), respectively. PM2.5 during these stages was significantly associated only with an increased likelihood of implantation failure, highlighting adverse impact of ambient PM2.5 on early pregnancy outcome. In addition, we observed relatively stronger associations in women with poor ovarian response, compromised embryo quality, and those undergoing fresh or double embryo transfers. This large-scale population-based study demonstrated the detrimental effects of high PM2.5 exposure for IVF women, shedding light on clinical and public health practices.

The commercial application of metal–organic frameworks (MOFs) in gas separation, catalysis, sensing, energy conversion, and storage inevitably leads to the release of MOFs into the environment, posing a great threat to the eco-environment. The toxic risk assessment of MOFs is necessary to achieve their sustainable applications. Reproducible and accurate measurement in toxicity assays is the first step in the risk evaluation of MOFs. However, a broad range of artifacts may occur in previous toxicity tests of MOFs due to diverse interferences. Therefore, control experiments are needed to discriminate such interferences and to revise the experimental protocol for the reduction and elimination of the artifacts. Herein, we present a review of the artifacts and control experiments in toxicity assays of MOFs in terms of MOF preparation, toxicity test, labeling and tracking, and co-exposure test. We also discuss the differences in the results of the toxicity test with and without a control experiment to illustrate the impact of the control experiment on the conclusion. We highlight the importance of a control experiment to reduce false negative or false positive results and to guarantee accurate toxicity data in the toxicity study of MOFs, which could advance the ecological risk assessment of MOFs as well as the safe-to-sustainable design of MOFs in tackling various challenges of future applications.

Microplastics (MPs) have become major contaminants in freshwater ecosystems. While numerous studies have characterized MPs in reservoirs, a comprehensive synthesis focusing on in-reservoir variations and dam-related influences is still lacking. This study investigates the spatial distribution of MPs in reservoir water and sediment based on data synthesized from 34 peer-reviewed studies covering 36 reservoirs across diverse climatic and hydrological regions worldwide, with a focus on the trapping effects of dams. Using a combination of generalized linear mixed models (GLMM) and generalized additive mixed models (GAMM), the study analyzed MP abundance patterns in relation to distance to the dam and identified key environmental and anthropogenic factors influencing their distribution. The results show that MPs tend to accumulate near dams, suggesting a trapping effect, while upstream MP concentrations decline with increasing distance. Vertical stratification patterns were observed in both water and sediment, indicating different transport mechanisms. Additionally, exposure to MPs significantly affected benthic organisms, particularly in terms of growth and reproduction, with effects intensifying over longer exposure durations. These findings highlight the need for improved monitoring and management strategies in reservoirs to mitigate MP pollution and its ecological consequences.

Emerging flame retardant (EFR) pollutants are ubiquitous in marine environment due to their extensive applications, and capacity for persistence and long-range atmospheric transport. The accurate analysis of EFRs in marine matrices remains challenging due to the inherently low sensitivity and selectivity in complex matrices, matrix-induced signal suppression, limited analytical throughput, and the lack of robust non-target screening protocols. This review provides an integration of recent methodological breakthroughs, encompassing sensitive instrumental approaches and innovative extraction and purification techniques for EFR detection in marine multi-matrix. The environmental occurrence and process of EFRs highlight that the roles of particle-mediated transport, plastic debris leaching, and photochemical degradation co-govern the fate of EFRs in marine environments. Furthermore, the review critically examines the ecological risks of EFRs, focusing on their bioaccumulation-driven toxicity, trophic magnification in marine food webs, and the potential for ecosystem destabilization. Mechanistic insights into photochemical transformation pathways are summarized, highlighting the formation of persistent and more toxic products that raise risks of chronic exposure and ecological disruption in marine environment. It provides a scientific foundation for regulatory agencies to assess marine environmental risks and implement targeted mitigation strategies. Future research should focus on quantifying the ecological impacts of EFRs to support a more effective monitoring and management framework.
