Summary: This study assessed persistent organic pollutants (POPs) for the first time in the Greater rhea from the Pampas grasslands of South America, revealing higher concentrations of POPs in populations living in intensive crop production areas, with PCBs being the most abundant pollutants. The study highlights the need for further research to evaluate the potential effects of POPs on the health of individuals and populations.

Summary: The anthropogenic impact on the aquatic environment of the Rasa River in Croatia was investigated. The study used yellow European eel as a biological indicator to analyze PBDEs, PCBs, DDT isomers, and major and trace elements. The results showed generally low contamination levels in the surrounding area, with organic contaminants increasing in muscle with lipid content, length, weight, and body condition. Metal(loid) levels decreased or remained unchanged with increasing size, except for a few elements that accumulated in the liver at the downstream location.

Summary: Organic matter from salmon farms can be assimilated by wild communities. The effect of assimilation on contaminant profiles differs among species. The imported feed to New Zealand has low levels of most organic contaminants and is unlikely to have significant ecological effects on adjacent habitats.

Summary: The study examined the association between gestational diabetes mellitus and persistent organic pollutants in placenta samples. Lower levels of PBDE and PCB were found in placenta of mothers with gestational diabetes mellitus, which was independent of other factors. This paper reported an inverse relationship between PBDE/PCB levels in placenta and gestational diabetes for the first time, suggesting potential for future research in this area.

Summary: This study evaluated the binding affinities of PCBs and PBDEs with the CAR_LBD of the Baikal seal and mouse using SPR biosensor, showing that PBDEs had higher binding affinities than PCBs for both CAR_LBDs; in silico docking simulations revealed that PBDEs had more non-covalent interactions with specific amino acid residues in both CAR_LBDs; the binding affinities were not consistent with the previously reported transactivation potencies of the congeners.

Summary: Honeybees are exposed to various anthropogenic environmental pollutants which can be transferred to their products. This study investigated residues of pesticides, PCBs, PBDEs, and PAHs in honey and propolis, finding that a significant percentage of samples were not suitable for human consumption due to contamination, with propolis more contaminated than honey samples.

Summary: Turkey's unique location allows it to receive air masses from Europe, Russia, Middle East, and Africa, making it a significant site for long-range atmospheric transport (LRT) of contaminants. Measurements in Istanbul and Izmir showed high levels of organochlorine pesticides, PCBs, and PBDEs, with DDT and HCH derivatives being dominant species. Temperature dependence indicates contributions from both LRT and local contaminated areas to elevated pollutant levels, with potential source regions identified in Africa, Middle East, Europe, and local metropolitan areas.

Summary: The study focused on the accumulation and elimination of two PCBs and a PBDE mixture in Northern leopard frog tadpoles under different temperatures. It was found that tissue concentrations of the toxicants were linearly related to dietary concentrations and elimination was faster at higher temperatures. The apparent activation energy for elimination played a crucial role, showing similar temperature sensitivities among different processes.

Summary: The objective of this study was to investigate the long-range atmospheric transport of selected POPs released as a result of military conflicts in the south of Turkey's borders. The study found that there was a decreasing trend in concentration with increasing distance from the border. Furthermore, the analysis indicated that the transport of these pollutants mainly originated from Europe, Russia, former Soviet Union countries, and North Africa, rather than the conflict areas.

Summary: The presence of marine vertebrates in Antarctic soils has an influence on trace element and soil organic matter levels, although it does not significantly increase the concentrations of these elements. There is evidence of selective enrichment, indicating a zoogenic influence. Soil elemental levels in this region are determined by a combination of local geology, vertebrate diet, and colony size.

Summary: Chemical pollution poses a major threat to marine ecosystems, especially to top predators like sharks, which are highly susceptible to exposure and accumulation of contaminants. This study examined the contamination levels, composition, and sources in blue sharks inhabiting the Northeast Atlantic, as well as the potential risk to human consumers. High levels of contaminants were found in most sampled sharks, with over 75% exceeding legal limits for human consumption. Consumption of meat from these sharks could potentially expose consumers to dangerous levels of methylmercury. Moreover, the assessment of single contaminants may underestimate the risk to human health, and the accumulation of contaminants in sharks appears to be influenced by their geographical distribution rather than other factors such as sex, size, or prey trophic level.

Summary: This study evaluated the levels of eighteen trace elements in feathers and eggs of five migratory species breeding on the Antarctic Peninsula, and their association with stable isotopes. It was found that the concentrations of Li and Mg in the feathers of South polar skua, which migrate to the Northern Hemisphere, were one order of magnitude higher than those of Snowy sheathbill, a southern migrant species. Feathers had higher concentrations for 11 out of 18 metals compared to eggs. The study also revealed that migration and trophic ecology influenced the concentrations of Fe, Mn, Cu, and Se in Antarctic seabird feathers.

Summary: Antarctic benthic organisms, especially sponges, have been found to bioaccumulate persistent organic pollutants (POPs). However, the role and contamination levels of sponges in Antarctica have been largely overlooked. This study evaluated the bioaccumulation of legacy chlorinated POPs in 35 sponge samples from different locations in Antarctica. The results showed that the overall contamination levels were comparable to other Antarctic benthic organisms, and the predominant contaminants were lower chlorinated organochlorines, indicating long-range atmospheric transportation as the main contamination pathway.

Summary: This study investigates the biomagnification of Poly- and Perfluoroalkyl Substances (PFAS) in striped dolphins in the North-Western Mediterranean Sea and examines the temporal trends of PFAS concentrations over the past three decades. The results show that PFAS, especially the long-chain compounds, have bioaccumulated in dolphins and may have potential health effects. The findings contribute to the understanding of PFAS pollution in marine ecosystems and can support future ecological risk assessments and management strategies.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
