Herein, the dynamic fluctuating effects of polystyrene (PS) on <em>Microcystis aeruginosa</em> were investigated throughout its growth cycle, as well as the action of algal organic matter in the disinfection by-products formation. The maximum inhibition of algal cell growth and phycobiliprotein content by PS during the adaptation phase reached 56.3% and 76.3%, respectively. With the extension of exposure time, the inhibitory effect gradually transitions into promotive effect. PS exposure increased the content of extracellular organic matter and enhanced the THMs formation during chlorination, with trihalomethanes concentrations of 62.8 and 101.9<!-- --> <!-- -->μg/L in the control and PS treatment groups, respectively. Moreover, the reactive oxygen species levels in PS-exposed algal cells were only 71.5% of those in the control group, and total antioxidant capacity levels, superoxide dismutase and catalase activities were also lower. However, the microcystin content exposed PS was increased to 1.2 times that of the control group. The presence of PS in aquatic environments increases the levels of algal organic matter and microcystin, potentially threatening water quality. This study provides new insights into the combined effects of microplastics on freshwater algae and valuable data on potential risk associated with MPs.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"121 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Co-contamination with NH₄⁺ and Pb²⁺ reduced ryegrass root ¹⁵N-total nitrogen (TN) by 30% while increasing soil ¹⁵N-NH₄⁺ residue by 95% and decreasing ¹⁵N-microbial biomass nitrogen (MBN) by 59%, compared to NH₄⁺ single contamination. DNA-SIP analysis revealed that ryegrass cultivation under NH₄⁺- Pb²⁺ co-contamination increased the abundance of plant growth-promoting rhizobacteria (<em>Dyella</em>), acid-tolerant nitrogen (<em>Acidibacter)</em>, and sulfur-cycling taxa (<em>Desulfosporosinus</em>). The presence of raffinose and chlorogenic acid in ryegrass root metabolites was associated with shifts in the structure and composition of using NH₄⁺ active microbial taxa.

Additionally, biofilm formation during TPHP degradation might explain its efficient degradation of hydrophobic compounds. Furthermore, strain RL-XB02 degraded TPHP via enzyme-mediated processes, with intracellular enzymes likely crucial. The metabolites identification and genomic analysis revealed that TPHP was transformed into phenol via stepwise de-esterification, which was assimilated by dual catechol branches of the β-ketoadipate pathway to cell growth. The molecular mechanisms of phenol catabolism were confirmed by RT-qPCR. Bioaugmentation of strain RL-XB02 could eliminate TPHP from marine samples and alleviate the toxicity of TPHP to plants. These findings advance our understanding of TPHP biodegradation pathways and propose a sustainable bioremediation strategy for TPHP contamination.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"30 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classified MPs simulation employed probability density functions and shape factors to convert mass concentrations into particle counts during the flood season in the Yangtze River estuary. The 5% species hazard concentration (HC₅) with two ecologically relevant metrics was selected as the MPC threshold by correcting the species sensitivity distribution (SSD) curves for polydispersity and biological accessibility of environmental MPs.

Average indoor concentrations of ozone and its oxidation products were 7.0 ppb and 24.6 ppb in residences, 12.5 ppb and 19.3 ppb in schools, and 12.7 ppb and 19.1 ppb in offices, respectively. Overall exposures averaged 10.9 ppb for ozone and 26.9 ppb for oxidation products, with oxidation product exposures exceeding ozone exposures across all age groups. Residences contributed 58.2% of ozone and 82.6% of oxidation product exposures due to lower air change rates and prolonged occupancy.

However, the effects of glyphosate-based herbicides (GBHs) on this adaptive mechanism remain unclear. To explore, we conducted a cross-design experiment on lizards (<em>Eremias argus</em>) under normal and elevated temperatures, with or without GBH exposure. We assessed maternal reproductive output, egg composition, embryo hatching performance, and the morphological and performance traits of offspring which were uniformly reared under warming regime. Under warming conditions, female enhanced reproductive output by reducing relative clutch mass and increasing egg-laying frequency. They also helped offspring adapt to warmer environments via maternal resource transfer, likely by the observed increases in unsaturated fatty acids and amino acids in eggs. Hatchlings from the warming treatment groups exhibited higher survival rates, underscoring the potential of maternal effect in thermal adaptation. GBH exposure in a warming environment led to reduced reproductive frequency, lower hatching rates, smaller hatchlings and decreased offspring thermal tolerance, diminishing the benefits of maternal effect. These effects may be linked to reduced levels of nucleotide metabolism-related substances, triglycerides, proline, and citrulline in eggs. Our study revealed the adverse effects of GBH on lizards and provided new insights into the impact of chemical pollutants on biological adaptability in the context of climate change.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"42 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
