In-situ adsorption-coupled-oxidation enabled mercury vapor capture over sp-hybridized graphdiyne.

Developing efficient and sustainable carbon sorbent for mercury vapor (Hg) capture is significant to public health and ecosystem protection. Here we show a carbon material, namely graphdiyne with accessible sp-hybridized carbons (HsGDY), that can serve as an effective "trap" to anchor Hg atoms by strong electron-metal-support interaction, leading to the in-situ adsorption-coupled-oxidation of Hg. The adsorption process is benefited from the large hexagonal pore structure of HsGDY.

Machine learning-based non-invasive continuous dynamic monitoring of human core temperature with wearable dual temperature sensors.

Objective: Due to the growing demand for personal health monitoring in extreme environments, continuous monitoring of core temperature has become increasingly important. Traditional monitoring methods, such as mercury thermometers and infrared thermometers, may have limitations in tracking real-time fluctuations in core temperature, especially in special application scenarios such as firefighting, military, and aerospace. This study aims to develop a non-invasive, continuous core temperature prediction model based on machine learning, addressing the limitations of traditional methods in extreme environments.

A comprehensive study of multiscale pore structural characteristics in deep-buried coals of different ranks.

The pore structure characteristics of coal significantly influence its gas adsorption and desorption capacity, as well as gas migration, playing a crucial role in the development of coalbed methane and the management of gas-related disasters. To investigate the pore distribution characteristics of coal in-depth, pore data for coal samples with varying degrees of metamorphism were obtained using low-pressure nitrogen adsorption (LPGA-N), low-pressure CO adsorption (LPGA-CO) methods, and mercury intrusion porosimetry (MIP). Multiscale pore size distributions were constructed for three types of coal samples.

Impact of repeated organic amendments on trace element exposure and health risks via the soil-vegetable-human pathway.

Applying organic fertilizers enriches soil with essential nutrients and organic matter. However, the trace elements (TE) often present in organic fertilizers-such as chromium (Cr), cadmium (Cd), mercury (Hg) and arsenic (As)-can pose food safety risks. Continuous use of organic amendments can lead to the accumulation of TE in the soil, increasing their uptake by plants and potential risks to human health.

Site-specific ontogenetic drivers of mercury concentrations in American alligators.

Contaminant body burdens are determined by complex interactions between contaminant inputs into the environment, local ecological dynamics, and organismal ontogeny. Although a naturally occurring element, mercury (Hg) is a potent neurotoxin, commonly assessed in contaminant body burdens. Anthropogenic activity has impacted its spatial distribution, resulting in regional 'hotspots' with elevated Hg concentrations.

Probabilistic Health Risk Assessment and Grading Benchmark Estimation of Atmospheric PM-Bound Heavy Metals in China.

The formulation of reasonable concentration classification standards can significantly enhance the protection of populations against atmospheric heavy metals, and the development of these standards should be grounded in national-level probabilistic risk assessment to establish multiple grading benchmarks. In this study, the probabilistic health risk assessment model was used for the first time to assess the health risks of hazardous metals [arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), and vanadium (V)] based on a publication dataset containing 57,737 PM-bound heavy metal samples from China. Our results showed that the average non-carcinogenic risk attributed to heavy metals in all provinces of China was less than 1.

Copper selenide enhanced magnetic biochar for elemental mercury removal from coal combustion flue gas.

With the rapid development of adsorbents for removal of elemental mercury (Hg) from coal combustion flue gas, the preparation of adsorbents with superior performance, lower cost and environmental friendliness remains an important challenge. An incipient wetness impregnation method followed by in-situ selenization was used to load copper selenide (CuSe) onto the surface of optimal magnetic biochar (OMBC). The results showed that CuSe significantly enhanced the Hg removal performance of the OMBC, and CuSe loading ratio of 10 % (10CuSe/OMBC) had the best Hg removal performance.

Morphological diversity of microglia: Implications for learning, environmental adaptation, ageing, sex differences and neuropathology.

Microglia are the brain resident macrophages that respond rapidly to any insult. These non-neuroectodermal cells are decorated with plenty of receptors allowing them to recognise and respond precisely to a multitude of stimuli. To do so, microglia undergo structural and functional changes aiming to actively keep the brain's homeostasis.

Long-term (1979-2024) trends and remobilization process of mercury pollution, the case study of Haifa Bay, Southeast Mediterranean Sea.

This study examines the interlink between long-term (1979-2024) trends of Hg contamination in sediments and commercial target fish species (Sargocentron rubrum, Diplodus sargus) and industrial Hg loads and their modes of entry to the marine system, using Haifa Bay (HB) in northern Israel and unpolluted reference sites as a case study. Historically, Hg levels in sediments and fish in HB fluctuated in response to industrial discharge from a former PVC factory. Despite a drastic regulatory reduction during the 1990s and the factory's closure in 2004, Hg levels in target fish species have shown an unexpected increasing trend, at rates of 1.
