Summary: The study investigated the concentration and partition of organic phosphorus flame retardants (OPFRs) in the Haihe Basin of China, revealing the widespread environmental contamination of oligomeric OPFRs. The results suggested that the emissions from manufacturing plants and airport operation were two important sources of OPFRs in the region.

Summary: The study investigated the distribution of organophosphorus flame retardants (OPFRs) in indoor dust, air, and ornamental plants in Dalian, China, and found that ornamental plants can be used as biosamplers for certain OPFRs in indoor air. A predictive model was developed to assess the partitioning coefficients of OPFRs between indoor air and plants, using lipid content in leaf cuticle for improved accuracy and reliability. The results suggest that indoor ornamental plants have the potential to be used as biosamplers of OPFRs in indoor environments due to their convenience and low cost.

Summary: This systematic review investigates the relationship between exposure concentrations of organophosphate esters (OPEs) in outdoor air and health risks, as well as correlations between OPE compounds in emission sources. The review identified 46 relevant studies and found that TCIPP, TMPP, TiBP, TPHP, and TCEP had the highest concentrations of OPEs overall. Principal component analysis revealed that F1 and F2 accounted for 49.81% of the cumulative contribution. The EDI values showed that TCEP, TCIPP, and TMPP posed the highest non-carcinogenic risks, and TCEP and TMPP had the highest carcinogenic risk values.

Summary: The study found significant differences in PFR and plasticizer concentrations among different insect taxa, with higher PFR concentrations in the larvae of litchi stinkbugs and grasshoppers, and higher concentrations in the adults of butterflies, moths, and dragonflies. Negative linear correlations were observed between the ratios of PFR and plasticizer concentrations in adult to larva and log KOW in the four studied insect taxa. Additionally, the contaminant concentrations in dragonfly ecdysis were significantly higher than in dragonfly larvae, indicating ecdysis as an important pathway for removing PFRs and plasticizers.

Summary: This study evaluated the removal efficiency of OPFRs and investigated the exposure risk in tap water in Hangzhou. The results showed a decline in OPFRs concentrations after treatment, and the exposure doses were much lower than the reference dose. However, residual levels and potential risks of OPFRs in the watershed should still be a concern.

Summary: As brominated flame retardants (BFRs) have been gradually banned and replaced by organophosphorus flame retardants (OPFRs), this study investigated the relationship between triphenyl phosphate (TPP) and glioma. The study utilized bioinformatics analysis and databases to identify TPP-related genes, gene expression data, and pathways. The analysis revealed the potential association of TPP with glioma and its impact on patients' prognosis.

Summary: Organophosphorus flame retardants (OPFRs), which are widely used, have been found in humans and the environment. This study used human biomonitoring (HBM) data to estimate the contribution of dietary intake to the total exposure of OPFRs. The estimated dietary intake ranged from 0.02 to 0.2 mu g/kg bw/d for TCEP, 0.05 to 0.17 mu g/kg bw/d for TCIPP, and 0.03 to 0.18 mu g/kg bw/d for TDCIPP. The estimated dietary intake of TDCIPP contributes 11-173% to the estimated daily intake (EDI), while the estimated dietary intake of TCIPP exceeds 100% in most calculations.

Summary: The presence of earthworms significantly enhances the microbial remediation of TBOEP-contaminated soil by promoting the removal rate of TBOEP and enriching TBOEP-degrading bacteria in the soil. The earthworms also stimulate soil peroxidase activity and increase dissolved organic matter content, facilitating the oxidative degradation of TBOEP and promoting the growth of degrading bacteria.

Through a case-control study based on the Shenzhen Aging-related Disorder Cohort, it was found that specific m-OPFRs metabolites in urine samples were positively associated with lower cognitive function. Additionally, a nonlinear dose-response relationship between urinary BDCIPP concentration and cognitive decline was observed.

Summary: The present study investigates the toxicity and metabolism of organophosphorus flame retardants (OPFRs) on earthworms. The findings indicate that exposure to tris(2-butoxyethyl) phosphate (TBOEP) inhibits acetyl-cholinesterase activity, alters calcium-dependent pathways, and affects weight gain, reproduction, and neurotoxicity in E. fetida. E. fetida shows the ability to accumulate TBOEP and promotes its metabolism through cytochrome P450 and glutathione detoxification pathways. These results provide important data for the assessment of environmental risk and removal of OPFRs in soil.

Summary: This study investigated the tissue-specific accumulation of organophosphorus flame retardants (PFRs) and plasticizers in black-spotted frogs and bullfrogs. Differences in pollutant concentrations among different tissues were found, with liver tissues showing significantly higher concentrations. Male frogs exhibited higher metabolic potentials for these chemicals, while no obvious correlations were found between OLR and log K-OW. Different parental transfer patterns were observed in frogs using different tissues as parental tissues, and liver tissues had similar parental transfer mechanisms with muscle tissues.

Summary: The study investigated the occurrence of thirteen OPFRs in breast milk samples collected from Beijing mothers in 2018, revealing China as one of the most affected regions by OPFRs. Personal characteristics of mothers were found to impact the levels of certain OPFRs in breast milk, with most nursing infants' daily OPFR intake not raising significant health concerns. However, two OPFRs, TPhP and EHDPP, were noted to have higher estimated daily intakes than corresponding reference doses, potentially posing health risks.

Summary: The destruction of PFAS is crucial for remediating contaminated matrices, but relying solely on DE or DRE to determine their destruction may not fully mineralize PFAS and could result in the release of remaining fluorocarbon portions. The formation of products of incomplete combustion (PICs), including greenhouse gases and potentially hazardous substances, further highlights the need for additional characterization.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
