Summary: The study found that dissolved organic carbon (DOC), alkali and alkaline-earth metals, sulfate, phosphorus, and other substances were significantly more concentrated in peat ice compared to peat porewaters from the active layer. During full freezing of the soil column in winter, there was a local maximum of enrichment in certain substances located 30-50 cm below the active layer. This research highlights the importance of assessing the consequences of permafrost thaw on surface aquatic systems.

Summary: Thawing of frozen soils in high latitude regions, especially permafrost peatlands, can release organic carbon, nutrients, and trace elements from pore ice, potentially impacting climate warming. The conventional method of evaluating labile soil components does not capture the native ice present in soil pores, leading to underestimation or overestimation of these components. This study analyzed direct pore ice samples from Siberia and compared them to water extraction methods. The results showed high concentrations of organic carbon, nutrients, carboxylic acids, and trace metals in the thawed and frozen layers, emphasizing the importance of considering dispersed ice in permafrost thaw scenarios.

Summary: Tropical peat swamps are important ecosystems that provide various services and contribute significantly to the export of dissolved organic carbon (DOC) and trace elements to peat draining rivers. This study investigated trace element dynamics and their relationship with estuarine processes, as well as the influence of DOC and pH on their distribution in rivers and estuaries on Borneo. The results showed initial release and subsequent scavenging of trace elements at different salinities, with different peak concentrations observed during different seasons. The study also confirmed the strong affinity of certain trace elements to DOC and the correlations between certain trace elements in the study sites.

Summary: We experimentally simulated the freezing-thawing cycles in peat soils of permafrost landscapes and found that it could significantly alter the distribution of bacteria, dissolved organic carbon (DOC), nutrients, and trace elements in the peat core. The changes may be caused by the physical disintegration of peat particles, leaching of peat constituents, and opening of isolated pores during the freezing front migration. However, the presence of multiple concentration maxima after freeze-thaw events suggests that using the chemical composition of peat ice as an environmental archive for paleo-reconstructions is not reliable.

Summary: In this study, the effect of biodegradation on inorganic elements in crude oil was investigated by analyzing 14 crude oil samples from the Miaoxi Sag of the Bohai Bay Basin, eastern China. The results showed that the differential enrichment of elements was associated with the effects of organic acids generated by biodegradation on the oil-water-rock interactions in the reservoir. Certain ratios, such as Mg/P and Mn/P, were proposed as indicators of the level of biodegradation.

Summary: The quality of lake wetlands has decreased due to elevated concentrations of certain trace elements. Consuming crayfish from these trace element concentrated lake wetlands can be hazardous for waterbirds and human health. This study quantified the bioaccumulation of Cd, Ni, Pb, and Zn in sediments and abdominal muscles of Procambarus clarkii in Caohai lake wetland, China. The results showed significantly elevated levels of Cd, Ni, Pb, and Zn in sediment, and some samples of crayfish had Cd, Pb, and Zn levels exceeding the maximum permissible limits. These findings suggest that lake sediment could be an important source of feed for P. clarkii and that normal consumption of crayfish posed low to no health risk for waterbirds and local inhabitants.

Summary: Despite the lack of knowledge about the mineralogical control on major and trace element speciation in river suspended matter (RSM), this study examines the mineral and chemical composition of RSM in a boreal river in Western Siberia and its tributaries. The results show seasonal variations in RSM concentration and mineral phases, with quartz, albite, smectite, and chlorite increasing with discharge, and illite and calcite showing no effect from seasons or discharge. Elemental composition also varied seasonally, with sodium, K, Si, Al, trivalent, and tetravalent hydrolysates increasing with discharge, while alkaline-earth metals, P, Mn, and As decreased. The study highlights the importance of considering seasonal variations and understudied winter baseflow RSM sources.

Summary: Thermokarst lakes in the Western Siberian Lowland play a significant role in controlling organic carbon and trace metal storage as well as greenhouse gas emissions. However, the knowledge about the colloidal forms of organic carbon (IC) and related elements in this region is limited. In this study, 38 thermokarst lakes were sampled and analyzed to quantify the relationships between the colloidal content of elements and factors such as lake surface area, permafrost coverage, pH, and concentrations of main colloidal constituents. The results showed positive correlations between lake area and the colloidal fractions of DOC, Ni, rare earth elements (REE), and Hf, as well as an increase in the colloidal fractions of certain elements from the permafrost-free zone to the permafrost-bearing zones.

Summary: Among the various exometabolitic effects of marine microorganisms, massive mucilage events in the coastal zones of temperate and tropical seas are the most spectacular and environmentally important. Abundant mucilage material in the form of aggregates appears in late spring/early summer in the water column of the Adriatic Sea. These macroaggregate biopolymers originate mainly from plankton exometabolites, with both autochthonous and allochthonous components, and strongly impact the tourism, fisheries, and economy of coastal countries.
