“…The average concentrations in the blank filters were the following (μg·m −3 ): 0.007 ± 0.004 Cd; and 0.026 ± 0.016 Pb. The detection limits were the following (μg·m −3 ): 0.010 Cd and 0.039 Pb, this is consistent with the metal detection limits in previous studies [ 52 , 53 ]. According to the river sediment tests, the average recovery rates of heavy metals ranged from 86.24% to 115.97%, the metal recovery rate meets the requirements [ 54 , 55 , 56 ].…”

PM2.5 can deposit and partially dissolve in the pulmonary region. In order to be consistent with the reality of the pulmonary region and avoid overestimating the inhalation human health risk, the bioaccessibility of PM2.5 heavy metals and the deposition fraction (DF) urgently needs to be considered. This paper simulates the bioaccessibility of PM2.5 heavy metals in acidic intracellular and neutral extracellular deposition environments by simulating lung fluid. The multipath particle dosimetry model was used to simulate DF of PM2.5. According to the exposure assessment method of the U.S. Environmental Protection Agency, the inhalation exposure dose threshold was calculated, and the human health risk with different inhalation exposure doses was compared. The bioaccessibility of heavy metals is 12.1–36.2%. The total DF of PM2.5 in adults was higher than that in children, and children were higher than adults in the pulmonary region, and gradually decreased with age. The inhalation exposure dose threshold is 0.04–14.2 mg·kg−1·day−1 for the non-carcinogenic exposure dose and 0.007–0.043 mg·kg−1·day−1 for the carcinogenic exposure dose. Cd and Pb in PM2.5 in the study area have a non-carcinogenic risk to human health (hazard index < 1), and Cd has no or a potential carcinogenic risk to human health. A revised inhalation health risk assessment may avoid overestimation.

“…41 Elevated levels of Mn, V, and Co in indoor air might be derived from the natural dust suspension of motor vehicles. 42 A previous study found higher concentrations of atmospheric fine particles (PM2.5) bound to Mn, V, and Co near major thoroughfares. 42 Thus, the strong pairwise correlation of Mn–V–Co found in maternal hair may result from traffic emission sources, and endogenous deposition may also contribute to both the weak correlation and reproducibility of these metal(loid)s in the three hair segments, which was in line with the characteristic distribution of Mn and V in the paired household dust samples.…”

However, the absence of a significant positive correlation between paired maternal hair and household dust samples indicated that dust particle exposure was not directly related to the accumulation of metal(loid)s in hair.…”

“…Our data suggested that increased sh consumption might be benecial for enhancing Se levels and removing Sb. Seafood has been conrmed to be rich in Se, 42 and seafood consumption has been found to be related to urine Se levels in pregnant women. 41,54 More data are needed to explore the relationship between sh consumption and Se-Sb metabolism, since Sb is an understudied metalloid, and its associations with spontaneous abortion, 55 GDM, 55,56 and lower birth weights 57,58 have been observed in previous studies, suggesting a negative effect on maternal health and fetal growth.…”

“…It could be attributed to the interaction with air pollution. In highly urbanized regions, the environmental concentration of Arsenic (As), cadmium (Cd), lead (Pb), and black carbon (BC) is high (56). PM2.5 is the mass of particles per cubic meter in the air, with a size (diameter) generally <2.5 micrometers (µm), and is well-known as delicate particulate matter (2.5 micrometers is one 400th of a millimeter) (57).…”

Background: The association between dietary selenium (Se) intake and osteoporosis-related fractures remains inconsistent. We aimed to examine the dose relationship between Se intake and incident fracture among Chinese adults.Methods: The dietary data were retrieved from the China Health and Nutrition Survey conducted between 1991 and 2011, and 17,150 participants aged above 20 were included. A 3-day, 24-h recall of food intake was performed to assess cumulative average dietary Se intake. The fracture was based on self-report in each survey between 1997 and 2011. The association between Se intake and fracture was tested by Cox regression, and the non-linear association was examined by restricted cubic splines (RCS).Results: There were 976 fracture cases during a mean of 10.2 years follow-up. In a fully adjusted Cox model, across the quartiles of Se intake, the hazard ratios (HRs) for fracture were 1.07 (95% CI .86–1.33), 1 (reference), 1.25 (95% CI 1.02–1.53), and 1.33 (95% CI 1.07–1.65). RCS showed a parabolic association (P non-linear = 0.037) between Se and fracture for men as well as a U-shape dose-response (P non-linear = 0.04) between Se and fracture for subjects living in highly urbanized areas.Conclusion: In conclusion, there is a non-linear association between selenium intake and fracture, with higher intake associated with increased risk. The shape of the association varies by gender and urbanization level.
