Assessment of Four Commonly Employed in Vitro Arsenic Bioaccessibility Assays for Predicting in Vivo Relative Arsenic Bioavailability in Contaminated Soils

Environmental Science & Technology (2009)

Albert L. Juhasz John Weber Euan Smith Ravi Naidu Matthew Rees

Currently, a number of in vitro methods are in use worldwide to assess arsenic (As) bioaccessibility in soils. However, a dearth of research has been undertaken to compare the efficacy of the in vitro methods for estimating in vivo relative As bioavailability. In this study, As bioaccessibility in contaminated soils (n = 12) was assessed using four in vitro assays (SBRC, IVG, PBET, DIN). In vitro results were compared to in vivo relative As bioavailability data (swine assay) to ascertain which methodologies best correlate with in vivo data. Arsenic bioaccessibility in contaminated soils varied depending on the in vitro method employed. For the SBRC and IVG methods, As bioaccessibility generally decreased when gastric-phase values were compared to the intestinal phase. In contrast, extending the PBET and DIN assays from the gastric to the intestinal phase resulted in an increase in As bioaccessibility for some soils tested. Comparison of in vitro and in vivo results demonstrated that the in vitro assay encompassing the SBRC gastric phase provided the best prediction of in vivo relative As bioavailability (R2 = 0.75, Pearson correlation = 0.87). However, relative As bioavailability could also be predicted using gastric or intestinal phases of IVG, PBET, and DIN assays but with varying degrees of confidence (R2 = 0.53−0.67, Pearson correlation = 0.73−0.82).

Independent Data Validation of an in Vitro Method for the Prediction of the Relative Bioavailability of Arsenic in Contaminated Soils

Environmental Science & Technology (2015)

Karen D. Bradham Clay Nelson Albert L. Juhasz Euan Smith Kirk G. Scheckel

In vitro bioaccessibility (IVBA) assays estimate arsenic (As) relative bioavailability (RBA) in contaminated soils to improve accuracy in human exposure assessments. Previous studies correlating soil As IVBA with RBA have been limited by the use of few soil types and sources of As, and the predictive value of As IVBA has not been validated using an independent set of As-contaminated soils. In this study, a robust linear model was developed to predict As RBA in mice using IVBA, and the predictive capability of the model was independently validated using a unique set of As-contaminated soils. Forty As-contaminated soils varying in soil type and contaminant source were included in this study, with 31 soils used for initial model development and nine soils used for independent model validation. The initial model reliably predicted As RBA values in the independent data set, with a mean As RBA prediction error of 5.4%. Following validation, 40 soils were used for final model development, resulting in a linear model with the equation RBA = 0.65 × IVBA + 7.8 and an R2 of 0.81. The in vivo–in vitro correlation and independent data validation presented provide critical verification necessary for regulatory acceptance in human health risk assessment.

Arsenic Relative Bioavailability in Contaminated Soils: Comparison of Animal Models, Dosing Schemes, and Biological End Points

Environmental Science & Technology (2015)

Jie Li Chao Li Hongjie Sun Albert L. Juhasz Jun Luo

Different animals and biomarkers have been used to measure the relative bioavailability of arsenic (As-RBA) in contaminated soils. However, there is a lack of As-RBA comparison based on different animals (i.e., swine and mouse) and biomarkers [area under blood As concentration curve (AUC) after a single gavaged dose vs steady-state As urinary excretion (SSUE) and As accumulation in liver or kidney after multiple doses via diet]. In this study, As-RBA in 12 As-contaminated soils with known As-RBA via swine blood AUC model were measured by mouse blood AUC, SSUE, and liver and kidney analyses. As-RBA ranges for the four mouse assays were 2.8–61%, 3.6–64%, 3.9–74%, and 3.4–61%. Compared to swine blood AUC assay (7.0–81%), though well correlated (R2 = 0.83), the mouse blood AUC assay yielded lower values (2.8–61%). Similarly, strong correlations of As-RBA were observed between mouse blood AUC and mouse SSUE (R2 = 0.86) and between urine, liver, and kidney (R2 = 0.75–0.89), suggesting As-RBA was congruent among different animals and end points. Different animals and biomarkers had little impact on the outcome of in vivo assays to validate in vitro assays. On the basis of its simplicity, mouse liver or kidney assay following repeated doses of soil-amended diet is recommended for future As-RBA studies.

Emerging contaminants antibiotic resistance genes and microplastics in the environment: Introduction to 21 review articles published in CREST during 2018–2022

Critical Reviews in Environmental Science and Technology (2022)

Lili Niu Weiping Liu Albert L. Juhasz Jun Chen Q. Lena

Antibiotic resistance genes (ARGs) and microplastics are two classes of emerging contaminants that are of significant concern worldwide. Due to the potential adverse effects associated with their exposures, these contaminants have been extensively investigated during the past decades. Here, based on 21 review articles published in Critical Reviews in Environmental Science and Technology (CREST) during 2018–2022, current knowledge on ARGs and microplastics are summarized. Topics cover their analysis, occurrence, transfer, transformation, and ecological and human health risks in aquatic, terrestrial and atmospheric environments. Further, strategies to remove ARG-related contaminants from wastewater, manure, and sludge are discussed. Limitations and challenges in investigating their transport, fate, risks and removal techniques are highlighted for future research. In addition, we emphasize the importance of the One Health perspective to study ARGs and microplastics to better manage their environmental behaviors and associated risks.

Isolation and Identification of Pyrene MineralizingMycobacteriumspp. from Contaminated and Uncontaminated Sources

Applied and Environmental Soil Science (2011)

Christopher W. M. Lease Richard Bentham Sharyn Gaskin Albert L. Juhasz

Mycobacterium isolates obtained from PAH-contaminated and uncontaminated matrices were evaluated for their ability to degrade three-, four- and five-ring PAHs. PAH enrichment studies were prepared using pyrene and inocula obtained from manufacturing gas plant (MGP) soil, uncontaminated agricultural soil, and faeces from Macropus fuliginosus (Western Grey Kangaroo). Three pyrene-degrading microorganisms isolated from the corresponding enrichment cultures had broad substrate ranges, however, isolates could be differentiated based on surfactant, phenol, hydrocarbon and PAH utilisation. 16S rRNA analysis identified all three isolates as Mycobacterium sp. The Mycobacterium spp. could rapidly degrade phenanthrene and pyrene, however, no strain had the capacity to utilise fluorene or benzo[ a ]pyrene. When pyrene mineralisation experiments were performed, 70–79% of added 14 C was evolved as 14 CO 2 after 10 days. The present study demonstrates that PAH degrading microorganisms may be isolated from a diverse range of environmental matrices. The present study demonstrates that prior exposure to PAHs was not a prerequisite for PAH catabolic activity for two of these Mycobacterium isolates.
