THS exposure is a potential health threat to children, partners of smokers, and workers in environments with current or past smoking, and needs further investigation. In this study, we hypothesized that thirdhand Electronic Nicotine Delivery Systems (ENDS) exposures elicit lung and systemic inflammation due to resuspended particulate matter (PM) and inorganic compounds that remain after active vaping has ceased. To test our hypothesis, we exposed C57BL/6J mice to cotton towels contaminated with ENDS aerosols from unflavored vape fluid (6 mg nicotine in 50/50 propylene glycol/vegetable glycerin) for 1h/day, five days/week, for three weeks. We assessed protein levels in serum and bronchoalveolar lavage fluid (BALF) using a multiplex protein assay. The mean ± sd for PM10 and PM2.5 measurements in exposed mouse cages were 8.3 ± 14.0 and 4.6 ± 7.5 µg/m3, compared to 6.1 ± 11.2 and 3.7 ± 6.6 µg/m3 in control cages respectively. Two compounds, 4-methyl-1, 2-dioxolane and 4-methyl-cyclohexanol, were detected in vape fluid and on ENDS-contaminated towels, but not on control towels. Mice exposed to ENDS-contaminated towels had lower levels of serum Il-7 (P = 0.022, n = 7), and higher levels of Il-13 in the BALF (P = 0.006, n = 7) than those exposed to control towels (n = 6). After adjusting for sex and age, Il-7 and Il-13 levels were still associated with thirdhand vaping exposure (P = 0.010 and P = 0.017, respectively). This study provides further evidence that thirdhand ENDS aerosols can contaminate surfaces, and subsequently influence lung and systemic health upon exposure.","PeriodicalId":73738,"journal":{"name":"Journal of environmental exposure assessment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136067761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to their widespread use, BPs enter into the environment, such as rivers, and hence may accumulate in aquatic organisms. In this study, we investigated the tissue-specific bioaccumulation of BPs in different wild fish species in the North and West Rivers of the Pearl River system, South China, and assessed the human health risks via fish consumption. Firstly, the pretreatment method for 15 BPs in different fish tissues (muscle, liver, bile, plasma, intestine, and stomach) was established, and the target BPs were analyzed using ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The total concentration of BPs in surface water was up to 1,530 ng/L. Bisphenol A (BPA), bisphenol F (BPF), and bisphenol F (BPF) were the dominant ingredients. BPs were widely detected in fish tissues. Among them, BPF had the highest detection efficiency and the concentration in fish muscle and liver tissues were 401 and 6,257 ng/g ww, respectively. BPA and BPAF had the highest detection efficiencies, with concentrations of 434 and 357 ng/g ww in intestine, respectively, and of 14 and 26 ng/g ww in stomach, respectively. BPA had the highest detection efficiency and concentration in fish bile up to 17,160 ng/mL. BPAF had the highest detection efficiency and concentration of 8 ng/g ww in fish plasma. Liver and intestine showed log bioaccumulation factors up to 6.93 L/kg, exhibiting high bioaccumulation ability for BPs into biota. The hazard quotients of human exposure risks of BPA via consumption of fish muscle were in the range of 4.97 × 10-4-8.97 × 10-4, indicating a low health risk of BPA through daily fish consumption.","PeriodicalId":73738,"journal":{"name":"Journal of environmental exposure assessment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135995182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent work suggests these inherent benefits of WBE can serve to support vulnerable communities worldwide, such as migrant populations. The topic of forced migration has gained significant attention in recent decades as conflict and climate change events have increasingly become major drivers of migration around the world. However, information on the health of displaced populations during times of active mobility is lacking due to several logistical and ethical challenges using conventional methods. As environmental, political, and humanitarian conditions continue to evolve, it appears necessary to pursue alternative and adaptable approaches to acquire the health status of such dynamic and vulnerable populations. Here, we propose a call to action to apply WBE in migrant populations to offer inclusive and minimally invasive health assessments in order to: (1) close data gaps in the health information of displaced populations actively traveling along migratory pathways; and (2) promote greater efficacy in deployed interventions. Suggestions to pursue urgent migrant-specific health priorities are proposed, including antimicrobial resistance (AMR), infectious diseases, and malnutrition, along with considerations to promote ethically sound investigation. Overall, these recommendations may serve as a foundation to support subsequent investigation, with the purpose of encouraging global collaboration to offer new insights into the health of migrant and/or forcibly displaced populations.","PeriodicalId":73738,"journal":{"name":"Journal of environmental exposure assessment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty soil samples were collected and analyzed within five cities in the Hexi Corridor in Northwest China. The ranges of ∑24OCPs, ∑DDTs, and ∑HCHs concentrations in the soil samples were 23.1-393 ng/g, 4.96-167 ng/g, and 3.40-97.5 ng/g, respectively. The residual OCPs in soil were dominated by DDTs and HCHs, accounting for 38.7% and 16.1% of ∑24OCPs. Source analysis shows that the HCHs come from historical application and possible recent pesticide use, and DDTs are mainly from early application residues that formed in aerobic environments created by agriculture ploughing, which aerates the soil. The risk assessment showed that the soil in the Hexi Corridor may have a potential risk of residual OCPs, and the carcinogenic risk (CR) was 1.90 × 10-7-6.12 × 10-7 for adults and 5.6 × 10-7-1.8 × 10-6 for children, but the hazardous index (HI) was 0.0093 to 0.2817 for adults and 0.032 to 0.932 for children. Only a few samples showed values higher than the acceptable range for children. Therefore, in this study area, there is a low health risk to local residents. Nevertheless, our results provide a strong rationale for ongoing risk assessment and management and, hopefully, eradication of OCPs in the environment.","PeriodicalId":73738,"journal":{"name":"Journal of environmental exposure assessment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48418329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the large-sized sewersheds may not provide suitable information for monitoring localized outbreaks. After the declaration of a community COVID-19 outbreak in two neighborhoods of Castellón (Spain), SARS-CoV-2 RNA levels were monitored in wastewater samples. Moreover, genomic sequencing was performed. Thirty-three samples were collected in 2020, distributed over three points of the sewage network, two of which were close to the areas where the cases were declared. The third point was located at the inlet of the municipal wastewater treatment plant (WWTP). The samples were analyzed by RT-qPCR, using specific N1 and N2 target regions. The sum of confirmed cases, with the date of symptoms onset within the 3 weeks before each sampling day, was calculated. SARS-CoV-2 RNA was detected on most days in the two sampling points at neighborhood level, and the detection became negative when the number of cases with symptoms onset during the last 21 days in the study areas decreased to 0 or 1 case. The genomic sequencing performed for RNA from wastewater and clinical samples showed the same variant. The detection of SARS-CoV-2 and the subsequent non-detection provided the epidemiologists in charge of controlling the outbreak with useful information to confirm its closure, complementing the clinical and epidemiological data. Our findings illustrate the value of wastewater surveillance for localized outbreaks, especially in situations of low incidence of COVID-19 at the broader community level.","PeriodicalId":73738,"journal":{"name":"Journal of environmental exposure assessment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46724832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have reported on the potential of exposure to arsenic (As) and other metal(loid)s from vaping, but little is known about the speciation of As in the inhaled aerosols, an important determinant of toxicity. Inorganic As (iAs) species AsIII and AsV are generally more hazardous than organic As species. This study aimed to investigate total and speciated As in condensed aerosols of popular commercial e-cig products and to compare them with regulatory exposure limits. High-performance liquid chromatography and inductively-coupled plasma mass spectrometry were used for As measurements of e-cig aerosol condensates. The analysis included samples from three types of e-cig devices: MODs, PODs, and disposable pod (d-POD) devices. iAs species were identified in all 23 analyzed e-cig aerosol condensate samples, with the highest aerosol concentrations measured in MODs. The geometric mean (range) iAs concentration of 2.3 (1.2-5.1) μg/m3 observed in MOD devices in this study exceeded the recommended exposure limit of 2 μg/m3 for 15-min or shorter inhalation exposures set by the United States National Institute for Occupational Safety and Health. These preliminary results suggest that iAs species are present in inhalable aerosols of some MOD products at levels above regulatory limits for iAs inhalation.","PeriodicalId":73738,"journal":{"name":"Journal of environmental exposure assessment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11382129/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67658064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Animals can accumulate and metabolize these novel flame retardants including novel halogenated flame retardants (NHFRs) and organophosphate flame retardants (OPFRs), which is of considerable significance to their internal exposure and final toxicities. In this review, recent studies on the metabolic pathways and kinetics of the two classes of novel flame retardants and the internal exposure and toxicity of their major metabolites are summarized. The results showed that the metabolic pathways of OPFRs were similar among various animals, while the metabolism kinetics (or toxicokinetics) were variable among species. O-dealkylation, hydroxylation and phase II conjunction were the most likely pathways for OPFRs. NHFRs might be metabolized through the pathways of debromination, hydroxylation, dealkylation, and phase II conjunction. We also suggested that di-alkyl phosphates (DAPs) and hydroxylated OPFRs (OH-OPFRs) were the predominant metabolites in the animal body. DAPs, 2,3,4,5-tetrabromobenzoic acid (TBBA) and 2-ethylhexyl tetrabromophthalate (TBMEHP) have relatively higher internal exposure levels in fauna, which might attribute to their high conversion rate and stability in the body. The metabolism of OPFRs and NHFRs in non-human animals may eliminate their acute toxicity but not their chronic toxicities (especially for endocrine-disrupting effects), which suggests attention should also be paid to the major metabolites. Based on the issues mentioned above, we proposed that the metabolic processes in multitrophic organisms, the transfer of major metabolites across the food web, and the co-exposure of the novel flame retardants and their metabolites in fauna are worth studying in the future.","PeriodicalId":73738,"journal":{"name":"Journal of environmental exposure assessment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67658082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
