A number of ninety-six hair samples from Sicilian fishermen were examined for total mercury detection by an Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. The mercury levels obtained were compared with mercury levels of 96 hair samples from a control group, in order to assess potential exposure to heavy metals of Sicilian fishermen due to fish consumption and closeness to industrial activities. Furthermore, the mercury levels obtained from hair samples were sorted by sampling area in order to verify the possible risks linked to the different locations. The overall mean concentration in the hair of the population of fishermen was 6.45 ± 7.03 μg g(-1), with a highest value in a fisherman of Sciacca (16.48 μg g(-1)). Hair mercury concentration in fishermen group was significantly higher than in control group (p < 0.01). There was no significant difference in hair total mercury concentrations between sampling areas (p > 0.05). The results of this study indicate a greater risk of exposure to mercury in Sicilian fishermen, in comparison to the control population, due to the high consumption of fish and the close relationship with sources of exposure (ports, dumps, etc.).

Background: Epidemiological research on the association between heavy metals and congestive heart failure (CHF) in individuals with abnormal glucose metabolism is scarce. The study addresses this research gap by examining the link between exposure to heavy metals and the odds of CHF in a population with dysregulated glucose metabolism.
Method: This cross-sectional study includes 7326 patients with diabetes and prediabetes from the National Health and Nutrition Examination Survey from 2011 to 2018.
Associations of Essential and Non-Essential Trace Elements' Levels in the Blood, Serum, and Urine in Women with Premature Ovarian Insufficiency.

Premature ovarian insufficiency (POI) is poorly understood, with causes identified in only 25% of cases. Emerging evidence suggests links between trace elements (TEs) and POI. This study is the first to compare concentrations of manganese (Mn), copper (Cu), zinc (Zn), selenium (Se), molybdenum (Mo), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) across urine, serum, and whole blood in women with POI compared to healthy controls (HC), aiming to explore their distribution and potential associations with POI.

More and more research is now being focused on the mercury contamination of remote mountain environments. This study aimed to explore the mountain soil of Tiger Hill, Darjeeling, through the lens of its mercury tolerant bacterial microbiome to characterize regional mercury pollution and isolate strains with mercury bioremediation potential. The soil bacteria isolated from the region displayed an extreme tolerance to mercury at previously unseen levels of up to 7 mg/mL.

Fish oil supplements for dogs are used therapeutically for various clinical conditions. However, products may be variable in quality, potency, and stability. The objective of this study was to analyze eleven canine fish oil supplements from two time points (2010 and 2021) for the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), polychlorinated biphenyl (PCB) arochlors, minerals, and vitamins A and D, and to compare their compositions to label claims.
