This study presents the spatial distribution of total dissolved Cu, Zn, Co, and V during an autumn survey in the East China Sea (ECS). Dissolved Fe and its organic complexation were also investigated. The present study aimed to evaluate the relationship between Cu, Zn, Co, V, D-Fe and its organic ligands and total dissolved phosphate (TDP) in the coastal waters of the ECS. A correlation analysis shows that Cu, Zn and D-Fe were nutrient-like metals, whereas Co and V were non-nutrient-like metals. A multivariate statistical analysis showed that TDP was associated with D-Fe, Cu, Zn and Co, but was not associated with V. Furthermore, TDP was observed to be positively related with D-Fe, while negatively with Fe', which indicated that the limitation of TDP decreased the uptake of Fe'. This paper improves our understanding of the association among trace metals, TDP and phytoplankton biomass in the ECS.

Fish is a significant source of animal protein for humans; however, it has a tendency to bioaccumulate toxicants from the environment. The present study assessed the health risks associated with potential toxic metals (PTMs) in differently processed catfish (Clarias gariepinus) from four markets in Abeokuta metropolis, southwestern Nigeria. A total of 60 samples were collected and analyzed for PTMs using an Atomic Absorption Spectrophotometer.

Summary: Elemental imaging provides detailed profiling of metal bioaccumulation, offering more precision than bulk analysis by targeting specific tissue areas. However, accurately identifying comparable tissue regions from elemental maps is challenging, requiring the integration of hematoxylin and eosin (H&E) slides for effective comparison. Facilitating the streamlined co-registration of whole slide images (WSI) and elemental maps, TRACE enhances the analysis of tissue regions and elemental abundance in various pathological conditions.

Carbon monoxide (CO) is widely recognized as a significant environmental pollutant and is associated with numerous instances of accidental poisoning in humans. However, it also serves a pivotal role as a signaling molecule in plants, exhibiting functions analogous to those of other gaseous signaling molecules, including nitric oxide (NO) and hydrogen sulfide (HS). In plant physiology, CO is synthesized as an integral component of the defense mechanism against oxidative damage, particularly under abiotic stress conditions such as drought, salinity, and exposure to heavy metals.

Saltmarshes serve as repositories for various metal species, primarily due to vegetation removal and mineralization processes. However, the significance of potassium (K), one of the three major nutrients (nitrogen, phosphorus, and K) essential for plant growth, has often been overlooked, particularly in the context of saltmarshes where the mechanisms of K transport via porewater exchange remain poorly understood. To address this knowledge gap, we conducted field observations and laboratory analysis, and developed a Rn mass balance model to quantify K fluxes via porewater exchange under physical, biological, and anthropogenic drivers.
