Summary: The study found that gut microbiota plays an important role in the bioaccessibility of heavy metals in different age groups, with significant differences in metal exposure risks between adults and children. The bioaccessibility of heavy metals is primarily influenced by the total concentrations of metals in soils, followed by soil pH and active Fe/Mn oxide.

Summary: The study found that the pollution level and bioaccessibility of toxic metals in road dust increased with decreasing particle size, and heavy metal contamination in winter dust was generally more serious than in summer. Public exposure to dust metals did not pose non-carcinogenic risks, but the risk levels of dust metals at some points in industrial and sensitive areas showed a deteriorating trend.

Summary: The pollution of heavy metals in soils of abandoned industrial sites in southeastern China is significant, posing risks to human health. Cd is the most susceptible to external factors, followed by Zn, Pb, Cr, Ni, and Cu. The bioaccessibility of heavy metals has a correlation with their bioavailability, and a regression model based on soil parameters can predict the bioaccessibility of heavy metals. The total concentration of heavy metals, Fe, soil texture, and pH control the bioaccessibility. The hazard index and carcinogenic risk values are significantly reduced when based on gastrointestinal bioaccessibility. This study provides a theoretical basis for the assessment of human health risks in abandoned industrial sites.

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: The study found that the application of hydroxyapatite, bentonite, and biochar significantly increased the residual fraction of Cd and Pb in soil, reducing their mobility, bioavailability, and bioaccessibility. However, the immobilization efficiency of these three amendments decreased over time.

Summary: This study evaluated the geochemical behaviors and potential environmental risks of heavy metals in smelter contaminated soil using mineral liberation analyzer (MLA) and complementary geochemical tests. The results showed that Cd, Cu, Mn, Pb, and Zn were more bioavailable, bioaccessible, and mobile among the studied metals. The study emphasized the importance of mineralogy analysis and geochemical approaches in understanding the contribution of smelting activities to soil pollution risks.

Summary: Growing concern has been paid to metals in soil-strawberry system, but few attempts have been made to investigate bioaccessible metals in strawberries and assess health risk. The connections between soil parameters and metal transfer in soil-strawberry-human system need further investigation. This study evaluated the accumulation status, migration, and health risk of Cd, Cr, Cu, Ni, Pb, and Zn in the PSS-strawberry-human system in China.

Summary: This study evaluated the bioaccessibility and health risks related to heavy metals and metalloid in airborne dust samples in Zabol, Iran. The results showed high carcinogenic risks associated with inhalation exposure for both children and adults, as well as elevated risks for ingestion and dermal contact pathways, particularly for children. The study highlights the significant health risks posed by toxic elements in airborne particles in Sistan and suggests the need for measures to reduce exposure and protect public health.

Summary: This study investigated the effects and mechanisms of microplastics (MPs) on the sorption-desorption, bioaccessibility, and bioavailability of cadmium (Cd) in paddy soil. The experiments showed that MPs significantly reduced Cd sorption in soil by covering the soil active sites and interrupting formation of CdCO3 and Cd3P2 precipitates. This led to an increase in Cd bioaccessibility and bioavailability in soil. The findings provide new insights into the impacts of MPs on the fate and risk of heavy metals in agricultural soil.

Summary: Heavy metals in urban dust could pose noticeable human health risks, with limited studies focusing on comprehensive health risk assessment incorporating bioaccessibility and source apportionment. Most heavy metals in urban dust were significantly enriched and influenced by human activities. By integrating bioaccessibility adjustments and source apportionment, lower non-carcinogenic and carcinogenic risks of heavy metals were observed, with traffic and industrial emissions and coal combustion dominating the risks. This study highlights the importance of considering bioaccessibility and source apportionment in health risk assessment for heavy metal contamination in urban dust.

Summary: This study evaluated potential practical techniques for chemical immobilization of molybdenum (Mo) contaminated agricultural soils using up to six different amendments from four materials. The results showed that biosolids, water treatment residues, and magnetite were effective in reducing molybdenum extractability and uptake by plants in lightly and moderately contaminated soils.

Summary: This study conducted a multidisciplinary analysis on soil, road dust, and house dust samples from a heavy industrial area in Greece, revealing the widespread presence of anthropogenic Fe-containing particles in all sampling media, which are associated with the bioaccessibility of most analyzed elements. By combining magnetic measurements, SEM/EDS analyses, bioaccessibility measurements, and isotopic analyses, it was found that industrial Pb and Pb related to the past usage of leaded petrol are the primary sources of solubilized Pb in simulated gastric and lung extractions.
