Arctic ecosystems face significant threats from chemicals of global concern. Persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) have been consistently detected in the Arctic through decades of monitoring. POPs are known to bioaccumulate in food webs, and both POPs an ...

We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petr ...

Global food trade expansion has enriched diets worldwide but also heightened concerns about contaminant spread. Per- and polyfluoroalkyl substances (PFAS) can persist in the environment for decades, yet their risks through food trade remain unclear. The global median estimated daily intake (EDI) ...

Substituted diphenylamine antioxidants (SDPAs) and synthetic phenolic antioxidants (SPAs), widely used in rubber and consumer products, pose growing environmental concerns. This study evaluated the occurrence and release of 43 SDPAs and 4 SPAs in raw leachate and treated effluent from 18 municipal landfills across China. Results showed 17 SDPAs and 1 SPA ...

Synthetic antioxidants (SAs), a group of emerging contaminants, have attracted great attention recently due to their widespread environmental occurrence and potential toxicity. Yet, there is a knowledge gap regarding their occurrence and associated infant exposure in baby wipes, one of the most frequently used baby products. Here, we analyzed SAs-includin ...

Recent data indicate that urban air harbors a complex mixture of industrial chemicals, pesticides, and combustion by-products, many of which may act as endocrine-disrupting chemicals (EDCs). By interfering with the endocrine system, EDCs can affect human health. Hence, there is an urgent need to ...

Air pollution is closely associated with increased lung cancer incidence and mortality. Because many semi-volatile industrial chemicals, pesticides and combustion by-products are endocrine-disrupting or genotoxic, their mixtures in outdoor urban air, even at trace levels, could have cumulative ef ...

To explore the use of molecular docking as a high throughput in silico screening tool for identifying chemicals of environmental health concern, we conducted a case study to assess endocrine disruption effects due to targeting of nuclear receptors (NRs) by chemicals with backbone structures like bisphenols, but with varied functional groups. The molecular ...

Organophosphate esters (OPEs) have emerged as a global environmental and health concern due to their persistent, bioaccumulative, and toxic (PBT) properties. Recently, their precursors-organophosphite antioxidants (OPAs)-and transformation products, which may exhibit greater persistence and toxicity, have gained attention as critical contributors to OPE-r ...

Sulfur autotrophic denitrification (SAD) offers a sustainable solution for nitrogen removal in low carbon to nitrogen ratio (C/N) municipal wastewater, yet its efficiency and startup time pose significant challenges. To overcome these, we developed iron-sulfur-modified carriers (FeS@MC) and integrated them into an in-situ sequencing batch reactor (S-Fe-SB ...

Bisphenol A (BPA) is a common endocrine disruptor widely found in commercial products. Despite negative human health effects, its usage is not fully banned worldwide with ongoing human exposure from sources including dust, aerosol particles, and surfaces. Although attention has been paid to the a ...
