Exposure to polystyrene microplastics and perfluorooctane sulfonate disrupt the homeostasis of intact planarians and the growth of regenerating planarians Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-12 Jinying Huang, Jianyong Zhang, Jingyi Sun, Mengxin Gong, Zuoqing Yuan
Microplastics (MPs) and perfluorinated compounds (PFAS) are widespread in the global ecosystem. MPs have the ability to adsorb organic contaminants such as perfluorooctane sulfonate (PFOS), leading to combined effects. The current work aims to explore the individual and combined toxicological effects of polystyrene (PS) and PFOS on the growth and nerves of the freshwater planarian (). The results showed

Hypoxia-inducible factor 1α inhibits heat stress-induced pig intestinal epithelial cell apoptosis through eif2α/ATF4/CHOP signaling Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-12 Hui Li, Gang Zhang, Yongqing Liu, Fan Gao, Xinyue Ye, Rutao Lin, Ming Wen
Unstoppable global warming and increased frequency of extreme heat leads to human and animals easier to suffer from heat stress (HS), with gastrointestinal abnormalities as one of the initial clinical symptoms. HS induces intestinal mucosal damage owing to intestinal hypoxia and hyperthermia. Hypoxia-inducible factor 1α (HIF-1α) activates numerous genes to mediate cell hypoxic responses; however, its

CDs-g-C3N4-oleaginous yeast hybrid system: Microbial lipid synthesis and fermentation residual reutilization Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-12 Yadong Yu, Shanshan Wang, Shaopeng Lv, Laiyou Wang, Shuxian Guo
The utilization of solar energy and fast-growing heterotrophic microbes for biofuel production has been recognized as a promising approach to achieve carbon neutrality and address energy crisis. In this work, we synthesized different kinds of photocatalysts based on graphitic carbon nitride (g-CN). We found that carbon dots modified-graphitic carbon nitride (CDs-g-CN) showed the highest photocatalytic

Temperature-phased anaerobic sludge digestion effectively removes antibiotic resistance genes in a full-scale wastewater treatment plant Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-12 Huan Liu, Zehao Zhang, Xuan Li, Ting Zhou, Zhenyao Wang, Jibin Li, Yi Li, Qilin Wang
Sludge is a major by-product and the final reservoir of antibiotic resistance genes (ARGs) in wastewater treatment plants (WWTPs). Temperature-phased anaerobic digestion (TPAD), consisting of thermophilic anaerobic digestion (AD) (55 °C) and mesophilic AD processes (37 °C), has been implemented in WWTPs for sludge reduction while improving the biomethane production. However, the impact of TPAD on the

Magnesium source with function of slowly releasing Mg and pH control for impurity-resistance synthesis ultra-large struvite from wastewater Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-12 Tong Zhou, Naiguang Xu, Guangyuan Chen, Meng Zhang, Tuo Ji, Xin Feng, Changsong Wang
Struvite (MgNHPO·6HO, Magnesium ammonium phosphate, MAP), recovered from wastewater, has potential application as a slow-release fertilizer. However, crystal size distribution (CSD) of recovered MAP typically lied in the range of 50–300 μm, due to fast nucleation rate and notably narrow metastable zone width (MSZW) of MAP, with purity levels 40–90 %. In order to control the rate of nucleation, a novel

Meta-analytical review of antioxidant mechanisms responses in animals exposed to herbicide 2,4-D herbicide Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-11 Ana Paula da Silva, Hilda Vanessa Poquioma Hernández, Camila Luiza Comelli, Miguel Angel Guillén Portugal, Fernanda Moreira Delavy, Tugstênio Lima de Souza, Elton Celton de Oliveira, Ciro Alberto de Oliveira-Ribeiro, Helena Cristina Silva de Assis, Nédia de Castilhos Ghisi
The 2,4-Dichlorophenoxyacetic acid (2,4-D) is a low-cost herbicide to eradicate broadleaf weeds. Since the development of 2,4-D resistant transgenic crops, it has been described as one of the most widely distributed pollutants in the world, increasing concern about its environmental impacts. This study aimed to elucidate the antioxidant system response in animals exposed to 2,4-D by different routes

Biomagnification of persistent organic pollutants (POPs) in detritivorous, phytophagous, and predatory invertebrates: How POPs enter terrestrial food web? Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-11 Xiaodan Wu, Siru Yu, Jiahe Zeng, Xiaobo Zheng, Zongling Ren, Yinghua Shu, Bixian Mai
Invertebrates are primary contributors to fluxes of nutrients, energy, and contaminants in terrestrial food webs, but the trophodynamic of contaminants in invertebrate food chains is not fully understood. In this study, occurrence and biomagnification of persistent organic pollutants (POPs) were assessed in detritivorous, phytophagous, and predatory invertebrate food chains. Detritivorous species (earthworm

Sources and transformations of riverine nitrogen across a coastal-plain river network of eastern China: New insights from multiple stable isotopes Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-11 Wenli Chen, Xiaohan Zhang, Nianting Wu, Can Yuan, Yinli Liu, Yue Yang, Zheng Chen, Randy A. Dahlgren, Minghua Zhang, Xiaoliang Ji
Riverine nitrogen pollution is ubiquitous and attracts considerable global attention. Nitrate is commonly the dominant total nitrogen (TN) constituent in surface and ground waters; thus, stable isotopes of nitrate (N/O-NO) are widely used to differentiate nitrate sources. However, N/O-NO approach fails to present a holistic perspective of nitrogen pollution for many coastal-plain river networks because

Limited contribution of photoenzymatic DNA repair in mitigating carry-over effects from larval UVB exposure: Implications for frog recruitment Sci. Total Environ. (IF 9.8) Pub Date : 2024-03-11 James Eduardo Lago Londero, Altevir Rossato Viana, Larissa Duailibe Silva, Cassiano Ricardo Schavinski, André Passaglia Schuch
Solar ultraviolet-B (UVB) radiation has increased due to stratospheric ozone depletion, climate and ecosystem changes and is a driver of amphibian population declines. Photoenzymatic repair (PER) is a critical mechanism for limiting UVB lethality in amphibian larvae. However, the link between PER and the UVB-induced effects remains understudied through long-term investigations . Here, we assessed how
