There is a body of evidence that ultrafine particles (UFP, those with diameters ≤ 100 nm) might have significant impacts on health. Accordingly, identifying sources of UFP is essential to develop abatement policies. This study focuses on urban Europe, and aims at identifying sources and quantifying their contributions to particle number size distribution (PNSD) using receptor modelling (Positive Matrix

There is increasing concern over the environmental risks associated with deepwater petroleum exploration activities. The integration of environmental risk assessment and oil spill modeling can help to understand and quantitatively characterize the potential risks from subsea blowouts in specific regions. This study integrates a novel deepwater oil spill model (DWOSM) and an extended stochastic modeling

Inhalable microorganisms in airborne fine particulate matter (PM2.5), including bacteria and phage, are major carriers of antibiotic resistance genes (ARGs) with strong ecological linkages and potential health implications for urban populations. A full-spectrum study on ARG carriers and phage-bacterium linkages will shed light on the environmental processes of antibiotic resistance from airborne dissemination

Per- and poly-fluoroalkyl substances (PFAS) are chemicals of concern—they are ubiquitous, persistent, with known and suspected health impacts. Well studied, primary sources of exposure to PFAS are drinking water and food. The presence of PFAS in human tissue of general populations suggests other important exposure sources/pathways. House dust measurements suggest widespread presence of PFAS in residences

A recent correspondence (Öberg, 2024) about our manuscript, Tampons as a source of exposure to metal(loid)s (Shearston et al., 2024), highlights the importance of data for complete risk assessment and public health communication when data gaps exist. Our study, which measured the concentration of 16 metals in tampons, detected the toxic metals lead (Pb), arsenic (As), and cadmium (Cd). Our study was

BackgroundPrenatal per- and polyfluoroalkyl substance (PFAS) exposures are associated with adverse offspring health outcomes, yet the underlying pathological mechanisms are unclear. Cord blood metabolomics can identify potentially important pathways associated with prenatal PFAS exposures, providing mechanistic insights that may help explain the long-term health effects. MethodsThe study included 590

We appreciate Dr. Canu for the helpful comments on our recent review paper “Indoor air quality in sub microenvironments: Pollutant characteristics, adverse health impacts, and population inequality”. We have carefully considered each point that Dr. Canu raised and will take this opportunity to clarify the references in this review for a better understanding of our study.

The functional endophytic bacterial community can effectively degrade polycyclic aromatic hydrocarbons (PAHs), thereby reducing their accumulation in vegetables grown on contaminated sites. However, the biological mechanisms underlying this reduction remain unclear. In this study, we analyzed the efficacy of different colonization methods of the functional endophytic bacterial community m5 in reducing

Studies on air pollution and outcomes of in vitro fertilization (IVF) have focused on couples undergoing autologous IVF, in which it is challenging to disentangle maternal and paternal exposures during gametogenesis. We sought to evaluate the independent associations between air pollution exposure during oogenesis and spermatogenesis on fertilization and embryo quality in non-identified donor oocyte

Per- and polyfluoroalkyl substances (PFAS) are fluorinated chemicals linked to adverse pregnancy and birth outcomes. However, the underlying mechanisms, specifically their effects on maternal inflammatory processes, are not well characterized.

Perfluoroalkyl substances (PFAS) are persisting chemicals with endocrine disruptive and carcinogenic properties. Previous studies involving cohorts with high PFAS exposure have not shown an increased risk of breast cancer. Research on PFAS and breast cancer according to hormone receptor status is limited. This study aims to investigate the association between PFAS exposure and hormone receptor-positive

In a recent paper published in Environmental International, Wang et al. conducted a review of subway indoor air quality and its potential effects on human health (subway users and workers), with the aim of providing stakeholders with state-of-the-art research findings (Wang et al., 2024). While this topic is undoubtedly of great importance, it is essential that such a review be based on a rigorous

The association between greenness exposure and semen quality and the underlying mechanism are unclear.

Monomethylmercury (MMHg) is a potent neurotoxin that poses a threat to human health. MMHg cycles in all spheres of the Earth but the sources and fate of atmospheric MMHg are unclear. Here, we develop a global model for atmospheric MMHg, which integrates the presently available data and indicates the limitations of the current study. Constrained by the observations in the atmosphere, the global atmospheric

Estimating the fraction absorbed (Fabs) of orally ingested chemicals in the human gastrointestinal tract is pivotal for assessing chemical concentrations in the systemic circulation and informing potential toxicological impacts, especially in the era of “new approach methods” targeting chemical screening and prioritization. Here, we present an input-parsimonious and computationally efficient approach

Exposure to perfluoroalkyl substances (PFAS) are reported to have numerous negative health effects and children are especially vulnerable. The aim of this study was to investigate whether maternal and infant PFAS burden have any impact on prenatal and postnatal growth, liver and lipid parameters in infants at age six months. Data on diet and growth parameters, as well as blood samples were collected

The high cadmium (Cd)-accumulating rice line Lu527-8 (H8) has already been proven to exhibit elevated Cd concentration and translocation over the normal rice line Lu527-4 (N4). H8 and N4 are sister lines that diverged from the same parents, while the molecular mechanisms underlying the genotypic differences in Cd enrichment between the two rice lines remains unclear. Here an in-depth exploration was

The nano zero-valent iron (nZVI) activated persulfate (PS) is recognized as a promising approach to degrade 2,2′,4,4′-tetrabromodiphenyl ether (BDE-47), which is ubiquitous in the soil at electronic waste sites. However, all the reported studies were performed in liquids, gaps in the real behaviour and microbial contribution to the degradation of BDE-47 in soil media need to be urgently filled. The

Over the last decades, great concern has been raised about possible adverse effects to human health due to exposures to radiofrequency electromagnetic fields (RF-EMF, 100 kHz – 300 GHz) emitted by wireless communication technologies. In 2011 the International Agency for Research on Cancer classified RF-EMF as possibly carcinogenic to humans, highlighting that the evidence was weak and far from conclusive

California’s diverse geography and meteorological conditions necessitate models capturing fine-grained patterns of air pollution distribution. This study presents the development of high-resolution (100 m) daily land use regression (LUR) models spanning 1989–2021 for nitrogen dioxide (NO2), fine particulate matter (PM2.5), and ozone (O3) across California. These machine learning LUR algorithms integrated
