Summary: This study estimated the bioaccessible concentration of different inorganics in soil samples from a firing range using two in vitro tests and discussed various options for incorporating bioaccessibility in HHRA for cleanup goal estimation. Results showed that despite differences in reagents and procedures, the two methods yielded similar results, with SBET method providing slightly higher values. The role of soil particle size distribution in calculating cleanup goals considering bioaccessibility was also discussed.

Summary: This study evaluated the bioaccumulation of chromium and nickel in rice grown in serpentine-derived paddy soils in the Philippines. Results showed that both metals were mainly accumulated in the roots of rice plants, with low health risks for male and female Filipino adults. Further studies are needed to understand the dynamics of heavy metal bioavailability in other crops and to ensure consumer safety in serpentine areas.

Summary: This review provides an overview of the current understanding of the risk assessment of plastic-associated residual additives in the marine environment, taking into account weathering and bioavailability. Organic and metal additive compounds have been found in leachates from plastics, and residual additives have been identified in weathered plastic particles collected from beaches and shorelines. However, studies on the uptake and bioaccumulation of plastic-associated chemicals are inconclusive, and there is a lack of research on hazard and risk assessments.

Summary: The study showed that soil bacterial communities in karst areas under different land use conditions exhibit differences in structure, potential functions, microbial interactions, and correlations with environmental variables, which enhances our understanding of how land use impacts microbial interactions and community assembly processes.

Summary: Organic contaminants released from military activities can be classified into infrastructure and base operations, training exercises and armed conflicts, containing potentially toxic compounds, energetic compounds, chemical warfare agents and military chemical compounds. Bioremediation and phytoremediation are considered eco-friendly and low-cost technologies for remediation.

Summary: In this study, PDMS vials were introduced as a sorption sink to improve the performance of physiologically based extraction test (PBET) for measuring the bioaccessibility of hydrophobic organic contaminants (HOCs) in soils. The results showed a significant correlation between in vitro and in vivo data, indicating the proposed method can accurately predict PCB bioavailability in soils. PDMS vials demonstrated high sorption capacity, reusability, and applicability to soils with a wide range of contamination levels.

Summary: This study evaluated the phytotoxicity to wheat root elongation in different soils across China and examined the biogeochemical processes of added Cr(VI). The results showed that soil properties, such as pH, organic matter, clay, cation exchange capacity, and amorphous Fe oxides, affected the toxicity of Cr. Wheat root elongation was found to be more sensitive to extracted Cr(VI) than Cr(III) after 105 days of incubation. A kinetic model indicated that pH, clay, and amorphous Fe/Al oxides played key roles in the aging and reduction processes of Cr(VI), while organic matter and cation exchange capacity greatly affected the aging process of Cr(III).

Summary: This study investigates the impact of high-carbohydrate, low-fat, low-protein and low-carbohydrate, high-fat, high-protein diets on bioavailable metals and gut microbes. The results reveal a diet-specific relationship between metal content and microbial reproduction. Furthermore, replacing the former diet with the latter leads to increased bioavailability of iron and chromium, as well as changes in beneficial and harmful microbial populations, and an increased risk of obesity, inflammation, septicemia, and cancer.

Summary: We collected 14 rice samples from Cd contaminated areas and determined the Cd relative bioavailability (RBA) in rice using in vivo mouse bioassay. Cd-RBA in rice correlated positively with calcium and amylose content but negatively with the concentrations of sulfur, phosphorus, phytic acid, and crude protein. Based on the total and bioavailable Cd concentrations in rice, weekly dietary Cd intake for adults was estimated. This study demonstrates the possibility of predicting Cd-RBA based on rice compositions and provides valuable suggestions for health risk assessment.

Summary: Understanding the transport of metal(loids) from soil to humans is crucial for human health risk assessment. Extensive studies have been conducted to assess human exposure to potentially toxic elements (PTEs) by studying their bioaccessibility and identifying influencing factors. This review focuses on in vitro methods used to determine the bioaccessibility of specific PTEs under different conditions. The findings provide insights on integrating relative bioavailability (RBA) in risk assessment and highlight the uncertainties and recommendations for using bioaccessibility data.

Summary: This article investigates the negative implications of untreated hospital waste and explores the proper methods for handling these waste. Conventional treatment methods can only remove a portion of the contaminants, while advanced treatment methods can efficiently remove contaminants. Additionally, the article introduces the environmental impacts of biomedical waste and the steps for proper handling to minimize health risks. This article is significant for efficient hospital waste management, especially during the COVID-19 pandemic when waste generation from hospitals globally has increased significantly.

Summary: This review examines the distribution and phytotoxicity of micro/nanoplastics in the soil environment, as well as the mechanisms of root uptake and mode of action. It finds that the partitioning of micro/nanoplastics to different soil matrices can affect their bioavailability to plants, and that uptake occurs through cellular endocytosis and aquaporin channels. The shape of the polymers also influences their uptake, and their bioaccumulation induces oxidative stress and alters gene expressions and metabolic pathways in plants.

Summary: Community/industrial wastewater is a major source of anthropogenic chemicals and its treatment is a challenging task for many countries. Emerging contaminants are widely present in the environment and have health effects on non-target organisms. Monitoring of these contaminants is crucial for understanding their status in aquatic environments.

Summary: Despite decades of research, population models in chemical risk assessment have limited practical utility. A novel application of Endogenous Lifecycle Models (ELM) offers cost-effective benefits, capturing endogenous lifecycle processes and estimating chemical impacts on avian lifecycles. ELMs prioritize general understanding over precision, integrating naturally with adverse outcome pathway framework for midtier risk assessment.
