ClearToxic mechanisms of nanoplastics exposure at environmental concentrations on juvenile red swamp crayfish (Procambarus clarkii): From multiple perspectives
Researchers exposed juvenile red swamp crayfish to nanoplastics at concentrations found in the environment and observed stunted growth, oxidative stress, liver and gill damage, and changes in gene activity. Different concentrations triggered different toxic pathways, including immune disruption and metabolic problems. Since crayfish are a widely consumed freshwater species, these findings raise concerns about nanoplastic contamination in the food supply.
Phycospheric Bacteria Alleviate the Stress of Erythromycin on Auxenochlorella pyrenoidosa by Regulating Nitrogen Metabolism
This study investigated how the antibiotic erythromycin affects the growth of the microalga Auxenochlorella pyrenoidosa and the bacteria living in its surrounding environment. Researchers found that while erythromycin initially inhibited algal growth, the microalgae gradually adapted over 21 days, partly aided by shifts in the composition of their associated bacterial communities. The findings suggest that phycospheric bacteria play an important role in helping microalgae cope with antibiotic contamination in water.
Assessment on the pollution level and risk of microplastics on bathing beaches: a case study of Liandao, China
Researchers assessed microplastic pollution levels on bathing beaches in Liandao, China, finding an average abundance of about 135 items per kilogram of sediment. Using pollution and hazard indices, the study determined that current microplastic contamination levels pose a low health risk, though the authors note that increasing population and consumption will likely raise plastic waste levels over time.
Study on the coupling coordination effect and dynamic relationship between tourism development and the ecological environment: a case study of Hainan Island
This study examined the coupling relationship between tourism development and ecological environment protection on Hainan Island, China, which has national strategic significance as a Free Trade Port. The research found that coordinating the two subsystems is critical for sustainable high-quality development on the island.
Independence Threat or Interdependence Threat? The Focusing Effect on Social or Physical Threat Modulates Brain Activity
Researchers conducted experiments to examine whether threats to independence versus interdependence differentially affect a focusing effect in social decision-making, where attention is disproportionately drawn to one option. The study found that interdependence threats produced a stronger focusing effect, with implications for understanding motivated cognition in social contexts.
Preliminary study of the source apportionment and diversity of microplastics: Taking floating microplastics in the South China Sea as an example
Researchers developed a source-specific classification system for floating microplastics in the South China Sea, analyzing surface water samples to estimate contributions from different land-based and ocean-based sources. The work advances understanding of which human activities contribute most to microplastic pollution in this heavily trafficked sea.
Occurrence and distribution of microplastics on recreational beaches of Haichow Bay, China
Microplastic occurrence and distribution were examined on recreational beaches of Haichow Bay, China, a heavily visited coastal area. The study found microplastics throughout the beach environment with patterns linked to beach use intensity, wave energy, and sediment type, establishing contamination data for a tourist-frequented coastline.
Effects of Metamifop on Defense Systems in Monopterus albus
Researchers exposed the rice field fish Monopterus albus to the herbicide metamifop at four concentrations, finding dose-dependent increases in reactive oxygen species, oxidative damage markers, and apoptosis indicators. The results demonstrate that metamifop poses toxicity risks to non-target aquatic organisms in paddy field environments.
Climatic and anthropogenic regulation of carbon transport and transformation in a karst river-reservoir system
Researchers analyzed dissolved inorganic carbon along a cascade of seven dam reservoirs in a karst river system in southwest China over one hydrological year, finding that cascading dams collectively exert a stronger effect on carbon cycling than single dams, with water temperature and hydraulic retention time jointly controlling how much carbon is retained or transformed.
Phylogenetic distance–decay patterns are not explained by local community assembly processes in freshwater lake microbial communities
This paper is not about microplastics; it studies how environmental factors and spatial distance drive microbial community composition in freshwater lake water and sediment.
Assessment on the Environmental Concern Level and Driving Mechanism of Beach Recreationists Based on the New Ecological Paradigm Scale
Researchers used the new ecological paradigm (NEP) scale to measure environmental concern levels among beach recreationists in China, finding 66.2% concern levels slightly above average urban resident levels with significant correlations to age, occupation, education, and income. The study constructed a behavioral group portrait model and analyzed driving mechanisms for pro-environmental behavior among beach visitors.
