Microelements metabolic disorders, including copper and zinc, constitute an important field of cancer studies. Efforts are undertaken to identify cancer markers. Found changes in plasma copper and zinc levels in patients with lung carcinoma may have clinical implications, and help in the diagnosis despite the fact that there are no reports in the literature confirming specificity of these two elements for lung carcinoma. Plasma copper and zinc levels were determined in blood samples of 94 patients with lung carcinoma with atomic absorption technique. The obtained results were compared with those in 20 healthy blood donors, and were analysed statistically and plotted graphically. Statistically significant differences in patient's plasma vs control group were noted.

Evaluation of Heavy Metal Contamination from Large-scale Swine-Farming Wastewater in Sichuan Province, China: Removal Efficiency, Spatial Distribution and Risk Assessment.
Bull Environ Contam Toxicol

The widespread application of swine-farming wastewater to soil and water is increasingly contributing to heavy metal contamination, posing significant environmental risks. This study investigated the concentrations of eight heavy metals in swine-farming wastewater following different treatment processes, and assessed their ecological risks in Sichuan Province, China. The findings revealed that zinc, copper and nickel exhibited the highest concentrations, potentially causing heavy or strong contamination levels and leading to heavy or slight ecological risks.

Background: Preterm birth (PTB) is a common pregnancy complication associated with significant neonatal morbidity. Prenatal exposure to environmental chemicals, including toxic and/or essential metal(loid)s, may contribute to PTB risk.
Objective: We aimed to summarize the epidemiologic evidence of the associations among levels of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), lead (Pb), and zinc (Zn) assessed during the prenatal period and PTB or gestational age at delivery; to assess the quality of the literature and strength of evidence for an effect for each metal; and to provide recommendations for future research.
Multi-metal mixture exposure and cognitive function in urban older adults: The mediation effects of thyroid hormones.

The existing studies on the association between multi-metal mixture exposure and cognitive function in the older adults are limited and controversial, with no studies considering the mediating effect of thyroid hormones on the connection between them. This study of 441 urban older adults assessed 21 urinary metal levels and cognitive function using the Mini-Mental State Examination (MMSE). Urinary metal levels were measured via inductively coupled plasma mass spectrometry (ICP-MS), and thyroid hormones levels were obtained from medical records.

The funarioid moss species , which is threatened with extinction, was the subject of this study. The riparian habitat type of this species is often under the influence of contaminated water, and, therefore, we tested the influence of selected potentially toxic elements (PTEs), namely zinc and copper, on the development, physiological features, and survival of the species on two different accessions (German and Croatian). The results obtained showed the different resilience of the two accessions to the PTEs.

Background/objectives: Food-insecure individuals are at risk for poor health outcomes, including substandard sleep health. A possible association of food insecurity with sleep regularity has not been explored, and factors contributing to the relationship between food insecurity and sleep are not well understood. This cross-sectional study explored the relationship between food insecurity and sleep regularity and identified specific nutrients that mediated the association.
