Summary: Antibiotic pollution is a common problem in the wetland of the Yellow River Delta caused by aquaculture industries. This study investigated the occurrence, bioaccumulation, and trophic transfer of antibiotics in the aquatic and terrestrial food webs of the YRD, and discussed the effects of physicochemical parameters on their behavior. The results showed that fluoroquinolones had the highest bioaccumulation capacity and the antibiotics were biodiluted in the aquatic food web while biomagnified in the terrestrial food web. Physicochemical parameters such as log Kow/log Dow and log Koa were found to be good predictors for antibiotic bioaccumulation in different organisms.

Summary: Research shows that run-of-river dams and other watershed disturbances alter carbon processing, promote Hg methylation and its accumulation at the base of the food web, leading to a temporary increase in Hg levels in fish.

Summary: Plastics are widely present in aquatic ecosystems and interact with organisms through trophic and non-trophic activities. Understanding these interactions is important for monitoring and assessing the risks of microplastics. In this study, the uptake and transfer of microplastics in a benthic food web were investigated using different freshwater animals.

Summary: The accumulation and trophodynamics of organo-phosphate flame retardants (OPFRs) and their metabolites were studied in the Pearl River estuarine food web of China. The concentration of OPFRs varied among different species, with the highest in crabs and the lowest in fish. The most abundant metabolites were di-alkyl phosphates (DAPs), with concentrations higher than or equal to their parent compounds.

Summary: In this study, the bioaccumulation and trophic transfer of arsenic in Daya Bay were systematically investigated. The results showed that arsenic concentrations in organisms and environmental samples varied by season and demonstrated biomagnification along trophic transfer in the food web. The study suggested that a benthic habit was an important promoter for arsenic biomagnification in marine food webs.

Summary: The study evaluated the concentration of heavy metals in different aquatic organisms in Swan Lagoon, China. Results showed that Cd, Cr, Cu, and Pb tended to be efficiently biodiluted with increasing trophic levels, while Zn increased with trophic level without biomagnification or biodilution.

Summary: Alternative pathways of energy transfer are essential for guaranteeing functionality and productivity in marine food webs. The complexity of zooplankton interactions, particularly the diversity of trophic niches, is crucial for stabilizing food web efficiency. Small, rarely studied zooplankton species like rotifers and ciliates play significant roles in the Baltic Sea pelagic primary production pathways.

Summary: This study analyzed the occurrence and trophic transfer of PCNs in polar ecosystems. It found that PCN concentrations in biota and marine sediments were relatively low and stable in both the Arctic and Antarctic regions. However, there were differences in trophic transfer patterns between the two regions, leading to different environmental risks.

Summary: Plankton in the Mediterranean Sea is influenced by various factors, such as size, food sources, biochemical composition, and trophic level, leading to differences in the bioaccumulation and biomagnification of mercury. Higher concentrations of monomethylmercury are found in oligotrophic regions, and plankton communities in the Southern Mediterranean Sea have lower concentrations compared to the Northern Mediterranean Sea.

Summary: This study evaluates the use of mercury concentrations in fish muscle tissue to determine a species' trophic position. The results suggest that mercury can serve as a viable indicator of a fish species' trophic position, reflecting regional, biological, and environmental factors.

Summary: The study investigated the distribution, bioaccumulation, and trophic transfer of heavy metals (HMs) in a typical grassland ecosystem based on biological classes and trophic levels. Different organisms showed varying levels of accumulation capacity for different heavy metals, with a strong bioaccumulation capacity for toxic arsenic observed across different trophic levels. Organisms at lower trophic levels were more likely to biomagnify zinc, while those at higher trophic levels were more likely to biodilute lead.

Summary: The study investigated the concentrations of metals in various organs of 17 marine species and found that liver, gill, and muscle tissues are ideal indicators for analyzing metal contamination in marine environments. The results showed both bio-dilution and tissue-specific bio-magnification of metals in the studied food web, emphasizing the importance of tissue-specific considerations in enhancing risk assessment of metal elements in wildlife and human health.

Summary: This study investigated the occurrence, bioaccumulation, and trophic magnification of 22 antibiotics in a subtropical food web from the Beibu Gulf. The research found distinct differences in antibiotic concentrations and types among marine taxa, with some chemicals showing trophic magnification through the food web. Additionally, the study highlighted the potential bioaccumulation of antibiotics in marine organisms based on their log D-ow values.

Summary: The nitrogen (N) cycle is crucial for maintaining nutrient balance and global climate stability in river systems. The construction of hydropower dams has significant impacts on N cycling, but there is still a lack of comprehensive summary on N cycling and its controlling mechanisms in reservoirs affected by dams.

Summary: The chronic exposure of freshwater ecosystems to engineered nanoparticles (NPs) shows negative effects on insect emergence and insect-mediated contaminant flux to riparian spiders. Copper and gold NPs lead to a significant decrease in insect abundance and an increase in metal transportation to riparian spiders. This study reveals the transfer of NPs from aquatic to terrestrial ecosystems and the adverse impact on insect and spider populations.

Summary: Metals and PAHs are common pollutants in urban streambed sediment, and their occurrence is highly variable. This study investigates the sources and contributions of PAHs and metals to streambed sediment, and finds that sealcoated pavement and pavement dust play significant roles in the contamination of urban streams.

Summary: Neonicotinoid mixtures are commonly found in streams worldwide, but their ecological impacts are not well understood. This study shows that exposure to neonicotinoids above certain thresholds can lead to a loss in taxa abundance and richness, disrupted adult emergence, and altered trophodynamics. The presence of neonicotinoid mixtures in California streams also poses greater than expected risks to stream health.

Summary: The increasing concentrations of selenium, nitrate + nitrite, and sulfate in the Koocanusa Reservoir and downstream in the Kootenai River are linked to expanding coal mining operations in the Elk River Watershed in Canada. The study found that the Elk River has experienced significant increases in concentration and load of these solutes, while the Kootenay River has only shown small magnitudes of change. The Elk River contributes a significant amount of flow and solutes to the reservoir, highlighting the potential impacts of coal mining activities. The current surface water treatment operations may not be sufficient to meet U.S. water quality standards in the Koocanusa Reservoir.
