“…In the general population, primary route of PAHs and metals exposure involves inhaling ambient air pollution, consuming contaminated food, and encountering dermal contact (McCormick et al, 2022;Xiao et al, 2021). At present, PAHs and metals pollution have become serious environmental problems (Han and Currell, 2017;Hashem et al, 2021), and epidemiological evidence has generally supported that exposed to them was related to adverse respiratory outcome. Among 1,000 individuals aged 22-25 years old from Sweden, researchers found that ∑OH-phenanthrene and ∑OHuorene were negatively associated with forced expiratory volume in 1 second (FEV 1 ), forced vital capacity (FVC), as well as 1-hydroxypyrene (1-OHP) with FEV 1 /FVC (Alhamdow et al, 2021).…”

Background: Polycyclic aromatic hydrocarbons (PAHs) and metals were associated with decreased lung function, but co-exposure effects and underlying mechanism remained unknown. Methods: Among 1,123 adults from National Health and Nutrition Examination Survey 2011-2012, 10 urinary PAHs, 11 urinary metals, and peripheral white blood cell (WBC) count were determined, and 5 lung function indices were measured. Least absolute shrinkage and selection operator, Bayesian kernel machine regression (BKMR), and quantile-based g-computation (qgcomp) were used to estimate co-exposure effects on lung function. Meditation analyses were used to explore mediating role of WBC. Results: These models demonstrated that PAHs and metals were significantly associated with lung function. BKMR models showed that comparing to all chemicals fixed at median level, FEV1/FVC, PEF, and FEF25-75% decreased by 1.31% (95% CI: 0.72%, 1.91%), 231.62 (43.45, 419.78) mL/s, and 131.64 (37.54, 225.74) mL/s respectively, when all chemicals were at 75th percentile. In the qgcomp, each quartile increase in mixture was associated with 104.35 (95% CI: 40.67, 168.02) mL, 1.16% (2.11%, 22.40%), 294.90 (78.37, 511.43) mL/s, 168.44 (41.66, 295.22) mL/s decrease in the FEV1, FEV1/FVC, PEF, and FEF25-75%, respectively. The 2-OHPh, 3-OHFlu, and Cd were leading contributors to the above associations. WBC mediated 8.22%-23.90% of association between PAHs and lung function. Conclusions: Co-exposure of PAHs and metals leads to lung function impairment, and WBC could partially mediate the relationship. Our findings clarify co-exposure effects of environmental mixtures on respiratory health and underlying mechanism, and suggest that focusing on highly prioritized toxicants would effectively attenuate the adverse effects.

“…Heavy metals persist long after they enter the ecosystem and are difficult to remove. The release of heavy-metal-rich industrial wastes can seriously contaminate soil, water, and air [ 11 ]. Importantly, studies have shown that metal dust is an environmental risk factor for a variety of allergic diseases (asthma, contact dermatitis, and hypersensitivity pneumonitis) [ 12 , 13 , 14 ].…”

Immunoglobulin E (IgE) is a type of immunoglobulin, and elevated serum total IgE is often present in allergic diseases. Exposure to environmental heavy metals has been markedly linked to allergic diseases, leading to elevated total IgE levels. However, studies concerning the effects of multiple metal exposures on total IgE levels are limited. Therefore, the current study seeks to explore the correlation between heavy-metal co-exposure and total IgE levels based on the National Health and Nutrition Examination Survey (NHANES, 2005–2006). Participants possessed complete data on total IgE levels, 11 urinary metal concentrations and other covariates. The correlations between 11 metals and total IgE levels were analyzed using multiple linear regression, and total IgE levels were a continuous variable. Total IgE levels exceeding 150 kU/L were considered sensitized. Binary logistic regression analyses were employed to assess the correlation between metal exposure and the occurrence of an allergic state. Then, the association between co-exposure to the 11 metals and total IgE levels or the occurrence of sensitization status was further analyzed by Bayesian kernel machine regression (BKMR), a multi-contaminant model. There were 1429 adults with complete data included. Based on the median concentration, molybdenum (Mo) had the highest concentration (46.60 μg/L), followed by cesium (Cs), barium (Ba), lead (Pb), and mercury (Hg). And the median (interquartile range) for total IgE levels was 43.7 (17.3, 126.0) kU/L. Multiple linear regression results showed that Pb was significantly and positively associated with total IgE levels (β = 0.165; 95% CI: 0.046, 0.284). Binary logistic regression showed a significant positive correlation between urinary Pb (OR: 1.258; 95% CI: 1.052, 1.510) and tungsten (W) (OR: 1.251; 95% CI: 1.082, 1.447). Importantly, the BKMR model found a positive correlation between combined-metal exposure and total IgE levels and the occurrence of sensitization status. The mixed heavy-metal exposure was associated with increased total IgE levels, and this association may be driven primarily by the exposure of Pb and W. This study provides new insights into the relationship between heavy-metal exposure and allergic diseases. More research is needed to confirm these findings.
