Summary: This study aimed to evaluate commonly used internal standards (ISs) in inductively coupled plasma-mass spectrometry (ICP-MS) and develop a protocol for evaluation. The results showed that In-115 was the most consistent IS, but it is necessary to screen soils prior to analysis to avoid interference from naturally occurring concentrations.

Summary: Impaired levels of trace elements such as selenium, zinc, copper, iron, manganese, and iodine can negatively impact the thyroid endocrine system by affecting oxidative stress and antioxidant defense. There is a limited number of studies that directly correlate trace element supplementation with the prevention or slowing down of thyroid diseases and the improvement of the antioxidant profile. However, some studies have shown that supplementation with zinc and selenium can reduce lipid peroxidation levels and improve antioxidant activity in thyroid diseases like hypothyroidism and autoimmune thyroiditis. This systematic review provides an overview of the current knowledge on the relationship between trace elements and thyroid diseases in terms of oxidoreductive homeostasis.

Summary: Heavy metals pose a serious risk to the normal functioning of living organisms. This study analyzed the concentrations of essential and toxic trace elements in the hair of horses in central Poland, as well as the interaction between these elements in the feed and hair. The results showed significant relationships between the concentrations of elements in the hair and oats, highlighting the importance of assessing essential heavy metals for monitoring exposure and the health of horses.

Summary: The study revealed that nickel in hairdressing cosmetics may have carcinogenic effects on hairdressers, negatively impacting their quality of life, unlike other trace elements tested such as lead, mercury, cadmium, and arsenic. Further research with tumor markers assessment is recommended to confirm the carcinogenic effect of nickel.

Summary: This study aims to understand the geochemical differences of soils in mangrove forests with different degrees of development in two semi-arid regions in Venezuela. The results showed that the soil in dwarf mangroves has limited capability to accumulate organic matter, while the soil dominated by fully developed mangroves has higher organic carbon content. Additionally, the soil in dwarf mangroves has higher concentrations of trace elements related to the chalcophile group, and the difference in soil chemistry between Rhizophora mangle and Avicennia germinans becomes significant in fully developed mangroves.

Summary: Non-ferrous metal mining is a significant source of toxic metal release to the environment, posing a threat to ecosystems and biota. This study analyzed bird feathers to assess the exposure of birds inhabiting non-ferrous metal mining sites to mercury, lead, and other trace elements. The results indicated contamination by mercury and lead in the feathers of birds in the mining areas, even after mining activities had ceased. Measures are needed to protect biota from overexposure to these toxic metals.

Summary: By creating homemade matrix-matched standards, quantitative imaging of iron, copper, and zinc in mouse brains was successfully achieved using laser ablation inductively coupled plasma mass spectrometry. This technique is expected to provide a new insight into the biological effects of metals and the etiology of metal-related diseases.

Summary: Trace elements are widespread contaminants that pose potential threats to ecosystems and human health. Migratory birds, such as the barn swallow, have been suggested as useful biomonitors for trace elements due to their ability to provide information on contaminants in remote areas. This study found distinct differences in the elemental profiles of feathers grown in African non-breeding areas and Italian breeding areas, with age also influencing the levels of trace elements in the birds.

Summary: This study investigated the composition of major, trace, and rare earth elements in 15 different species of wild edible mushrooms and their uptake affected by urban pollution. The results showed a wide variability in the composition of mushrooms, influenced by multiple factors. Risk assessment revealed potential adverse health effects from consuming excessive amounts of mushrooms studied, whether from urban areas or forests.

Summary: This review provides recent published information on trace elements from edible insects from various environments. Insects are gaining popularity as food proteins, especially in developing countries, and there is a higher demand for edible insects due to their nutritional value similar to meat. Edible insects are considered a readily available source of proteins, carbohydrates, and chitin, as well as trace elements such as iron, zinc, copper, and manganese. However, research on this topic is limited, and there is a need for comprehensive understanding of trace element contents in edible insects to prevent mineral deficiency in humans and animals.

Summary: This study analyzed the elemental concentration, mineralogy, and morphology of street dust samples using various methods. The results showed that Sb, Cu, and Zn were significantly enriched in areas with higher traffic loads, while Sn, Pb, and Cr showed moderate contamination. Geochemical indices and source identification techniques confirmed that these pollutants mainly originated from anthropogenic sources. Monte-Carlo simulations revealed that children are at a higher risk of exposure to these metals through skin contact and ingestion routes.

Summary: The study found differences in the probability of retraining towards tourism in rural areas of Chile, especially among those with higher education and women. Therefore, when formulating public policies aimed at promoting labor reconversion in rural areas, specific characteristics of different regions must be taken into consideration.

Summary: This study examines the relationship between sustainable mining practices and the well-being of rural communities in China. The findings suggest that improving mining efficiency is positively correlated with common prosperity, while rapid growth in the rural population has a negative impact. Additionally, investments play a significant role in promoting rural prosperity. To advance both sustainable mining and rural well-being, policy initiatives should focus on digitalization, the creation of green jobs, and the promotion of rural green entrepreneurship.

Summary: The study found that, with the decline in agricultural labor force, the proportion of migrant workers in the agricultural sector in several regions is increasing over time. Migrants living in rural areas are more likely to be unemployed and face economic hardship, while migrants employed in agriculture are more likely to work in elementary occupations and temporary jobs. The case studies on Italy and Spain demonstrate that the size of the migrant population is related to the typology of agricultural land use and labor intensity and seasonality of cultivation.

Summary: A new method was developed for quantifying Cr(III) and Cr(VI) in Chromium-enriched yeast, using ion chromatography-inductively coupled plasma mass spectrometry. Cr(III) and Cr(VI) were extracted using ultrasound-assisted weakly alkaline EDTA solution combined with boiling, and separated on two successive anion-exchange columns. The method was sensitive, accurate, and precise, with no Cr(VI) species found in CrY.

Summary: As the use of herbs increases worldwide, there are more reports of interactions between herbs and drugs. The complex active components of herbs inevitably affect the pharmacokinetics of chemical drugs in vivo. The expression of drug transporters is closely related to the absorption, distribution, metabolism, and excretion of drugs. When herbs inhibit or induce the expression of transporters, it can result in changes in substrate pharmacokinetics, affecting the efficacy and toxicity of drugs. This article summarizes the tissue distribution and physiological functions of drug transporters, analyzes the effects of herbs on drug transporters, and discusses the possible mechanisms of herb-drug interactions, providing ideas and references for safe clinical drug use.

Summary: Chromium (Cr) is essential for carbohydrate, lipid, and protein metabolisms in humans and animals. Chromium-enriched yeast (CrY) is a commonly used dietary supplement but its pharmacokinetics remains unclear. This study found that CrY was rapidly absorbed into the blood and slowly eliminated after oral administration in rats, which could lead to the accumulation of chromium in vivo.
