Summary: Lead exposure remains a major concern for professions involving firearms, especially with the increasing number of women in these roles. Personal air sampling during a training course showed that despite low external lead exposures, there was a significant increase in systemic exposure for cadets. Additional measures are needed to reduce lead exposure, particularly for instructors.

Summary: This study investigated the association of heavy metals such as lead, cadmium, and mercury with pterygium. The results suggest that environmental exposures to lead and mercury may be related to the development of pterygium in Korean general adults.

Summary: This study found that exposure to various estrogenic endocrine disruptors (EDs) can cause behavioral alterations in zebrafish during the embryonic period, including three previously unknown bisphenol substitutes. However, there is currently no consensus on the effects of these substances. Although these behavioral changes are unrelated to the specificity or structure of substances that regulate brain aromatase (aroB), the behavioral effects of estrogenic EDs should not be neglected in the context of environmental safety.

Summary: This study found that developmental exposure to common contaminants led to sex-specific and tissue-specific differences in DNA hydroxymethylation in mice. Female mice showed differences in blood hydroxymethylation, while male mice showed differences in both blood and cortex hydroxymethylation. These findings suggest potential biomarkers of exposure or long-term health effects.

Summary: Elevated blood cadmium and lead exposures are positively associated with higher red blood cell distribution width (RDW), especially in women and individuals with low-to-normal mean corpuscular volume (MCV). The associations may suggest hemolytic or erythropoietic mechanisms by which exposure increases mortality risk.

Summary: This study aimed to evaluate the effects of five toxic metals and polychlorinated biphenyls (PCBs) on DNA methylation in umbilical cord blood. The results showed that levels of lead (Pb) and antimony (Sb) were positively correlated with DNA methylation content. This suggests that global DNA methylation may be a promising biomarker for prenatal exposure to Pb and Sb.

Summary: During intensive manual microelectronic soldering activities, very low levels of lead emissions to air and surfaces were observed, especially in terms of lead released during soldering operations.

Summary: The study found that methamphetamine can easily move from contaminated materials in a home into the air, providing an exposure pathway and a mechanism for transfer throughout the property. The inhalation exposure pathway has the potential to result in significant intake of methamphetamine, adding to dermal absorption and ingestion exposure routes.

Summary: The study shows that during wildfire smoke events, residents in wealthy areas are more concerned about air quality and health protection, while those in lower-income neighborhoods exhibit less awareness of health protection and spend less time at home, with more neutral emotional responses. The reliance on self-protection in current policies to mitigate smoke health risks may not be effective and could lead to unequal benefits.

Summary: This passage discusses the paradigm shift in human chronotoxicity of xenobiotics, emphasizing the impact of synchronization between environmental insults and biological clocks on physiological response and disease phenotypes. Synchronization is defined as the totality of elements that appear during the same time period within a system, and desynchronized interfaces may lead to adverse health effects.

Summary: Pharmaceutical compounds, along with pesticides, heavy metals, and personal care products, are emerging contaminants that pose a major concern for aquatic ecosystems. The presence of pharmaceuticals can affect both freshwater organisms and human health through non-target effects and contamination of drinking water sources. This study explored the molecular and phenotypic alterations of commonly found pharmaceuticals in aquatic environments in daphnids, finding changes in enzyme activities and metabolic perturbations. Chronic exposure to low concentrations of pharmaceuticals resulted in significant alterations in metabolic and physiological endpoints.

Summary: We conducted a Mixture Risk Assessment (MRA) case study to evaluate the dietary exposure to various food contaminants and its impact on cognitive abilities. Lead, methylmercury, inorganic arsenic (iAs), fluoride, non-dioxin-like polychlorinated biphenyls (NDL-PCBs), and polybrominated diphenyl ethers (PBDEs) were found to contribute to IQ loss. The assessment was performed for different age groups in nine European countries, with all populations exceeding tolerable levels. Uncertainties were identified in terms of co-exposure, assessment group membership, reference values, and exposure data, which requires probabilistic modeling for an overall uncertainty estimate and can be utilized for future MRA improvement for cognitive decline.

Summary: This study analyzed the thermoluminescence (TL) glow curves of the polymer pencil lead graphite (PPLG) to determine the physical parameters of defects and the lifetime of TL process. Different methods were used to fit TL glow peaks of PPLG samples with varying diameters, and the results were compared to discuss implications about possible deconvolution of glow curves.

Summary: The study found that there is isotopic heterogeneity in lead white within individual paintings, while pure pigment from 16th-century Venetian lead white is isotopically homogeneous. The evolution from pure pigment to artwork is associated with an increase in the heterogeneity of lead isotope ratios.
