Summary: This study analyzed whole blood concentrations of 12 elements in the Canadian population using biobank samples from the Canadian Health Measures Survey. Most elements had concentrations below the method reporting limit, with only bismuth and lithium detected in the Canadian population. The results provide important information for characterizing exposure and assessing potential health risks.

Summary: Analyzing whole blood samples from a population-based study in Norway, the study investigated the concentrations of 28 trace elements in the general population of the Nord-Trondelag region. Findings suggested low exposure to toxic trace elements in the region, with differences in concentrations related to geographical locations and individual lifestyle factors.

Summary: This study describes the changes in urinary extracellular vesicles associated with decreased renal function in children. Proteomic analysis identified differentially expressed proteins in the urine extracellular vesicles of patients with congenital renal hypoplasia, reflecting the decreased renal function. A prototype ELISA system was also developed to quantify the expression of molecules representing this signature, which could detect early stages of decreased renal function.

Summary: Researchers studied the alteration of urinary extracellular vesicles (uEVs) to reveal characteristics associated with decreased renal function during childhood. By analyzing differentially expressed proteins in uEVs, they identified expression signatures related to congenital reduced nephrons. The prototype ELISA system showed potential in early detection of renal function decline, providing a non-invasive method for diagnosing kidney diseases.

Summary: The study found that the main accumulation organs of trace elements in commercially important fish along the southeast coast of India are different, and the concentration of toxic trace elements in the edible portion is lower than the international legislation limits.

Summary: Previous studies have shown that haemodialysis patients have an increased risk of trace element imbalances. In this study, both serum and whole blood concentrations of a wide panel of trace elements in haemodialysis patients were determined and compared with those of a control group. The results indicate that chronic haemodialysis may affect intra- and extracellular blood compartments differently, leading to significant trace element imbalances.

Summary: The study analyzed trace elements in surface sediment samples collected in 2014 to assess the pollution level and changes in the Wadden Sea. Cluster analysis and principal component analysis revealed three distinct sub-catchments, and discriminant analysis confirmed the classification. The study also demonstrated the representative nature of the sampling strategy for sediment characterization.

Summary: Honey is highly valued for its beneficial properties, but it is also susceptible to counterfeiting. Analytical methods are being developed to verify its origin and authenticity using trace- and ultra-trace elements. Lanthanides have been found to be particularly useful for tracing the link between honey and the soil it originates from. The study used ICP-MS and ICP-OES analysis to investigate the traceability of 17 different honey chains, and found that while the soil fingerprint remains unchanged, there is slight fractionation of heavier lanthanides from flowers to honey.

Summary: The interest in determining the chemical composition of textile products has increased due to toxicological issues and environmental concerns. This study analyzed the levels of twenty trace elements in clothing items commercialized in Spain and evaluated the potential health implication of dermal exposure in early life. Aluminum, zinc, and titanium showed the highest concentrations, while chromium was found in high levels in black polyester. Dermal exposure to titanium was associated with a hazard quotient higher than the threshold value, indicating potential risks for pregnant women and newborns.

Summary: Bottlenose dolphins in coastal and estuarine ecosystems are exposed to multiple stressors and can bioaccumulate contaminants. This study used a lipidomics approach and trace element analysis to characterize the lipid composition and correlations with trace elements in bottlenose dolphin blubber. The results provide insights into the physiological functions and risks that anthropogenic activities pose to coastal organisms.

Summary: The study revealed variations in major and trace element levels in Jordanian honey, with local honey showing higher levels of strontium and total REEs, while imported honey had very low levels of toxic elements, indicating higher safety. Discrimination between imported and local honey would require analysis of a large number of samples (>100) and use of advanced statistical models.

Summary: This study investigated the baseline biological exposure of the Nunavik population to rare earth elements and other chemicals before potential mining development. While most rare earth elements were not detected in the samples, elements like arsenic, antimony, chromium, and cobalt were detected in 100% of the samples, with concentrations higher than the general Canadian population in some cases.
