However, the basicity of solid alkali catalysts originates usually from electron-rich atoms such as oxygen and nitrogen, rather than electron-deficient metal species. This typically induces aggregation and leaching of active sites, and difficulty in recycling. Here we synthesized a photothermal catalyst made of stable and uniformly dispersed graphene-like biomaterial anchored neighboring potassium single atoms. The production of biodiesel from various acidic oils over this catalyst was evaluated by life cycle assessment and cost analysis. Infrared thermal imaging and finite element simulations were used to study the light-induced self-heating process. We further studied the alkaline behavior of neighboring potassium single atoms by carbon dioxide chemisorption and quantum calculations. Results show biodiesel yield of 99.6% at room temperature, which is explained by a good local photothermal effect at the solar interface and the presence of superalkali sites in the atomic potassium-containing biomaterial. The global warming potential measured for this system resulted in a net negative CO<sub>2</sub> emission of −10.8 kg CO<sub>2</sub>eq/kg. The photothermal catalyst can be recycled with almost no decline in reactivity.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"22 4","pages":"1607 - 1613"},"PeriodicalIF":15.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140230359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Crustaceans are particularly susceptible to heavy metal pollution in aquatic ecosystems due to their benthic and sedimentary lifestyle. Here we review crustaceans contamination by heavy metals with a focus on metal sources and dynamics, interaction of metals with other pollutants, metal analysis, bioconcentration and bioaccumulation, toxicity, and strategies to control metals. We observed that crustaceans tend to accumulate more heavy metals than other aquatic animals. Consequently, in certain regions of the world, consuming crustaceans as food may potentially threaten human health. The bioavailability, transport, and interaction of heavy metals with other pollutants depend on various factors, potentially leading to differential toxicity. Heavy metals induce multiple toxic effects on crustaceans, including metabolic dysfunction, genotoxic effects, respiratory impairments, DNA damage, sperm mobility, and quantity, and these poisonous effects will intensify with prolonged exposure time and increasing concentration. The concentration of heavy metals in crustacean samples is usually determined by inductively coupled plasma optical emission spectrometry and mass spectrometry. Approaches to reducing this potential threat include proper industrial wastewater treatment and using low-cost adsorbent materials in aquaculture.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"22 3","pages":"1391 - 1411"},"PeriodicalIF":15.0,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140257214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In particular, penetration of silver nanoparticles through the placental barrier is likely to damage the offspring. Here, we review hazards of silver nanoparticles with focus on exposure during pregnancy, toxicokinetics at maternal and fetal layers, ex vivo and in vivo placenta transfer models, and factors affecting the transfer. Exposure occurs by oral uptake, inhalation, dermal contact, and systemic administration. Toxicokinetics include absorption, distribution in tissues, metabolism and excretion. The accumulation efficiency is primarily influenced by the mode of exposure. Injection exhibits the highest bioavailability, followed by inhalation and oral uptake. Particles within the range of tens of nanometers are capable of crossing the placenta, according to an ex vivo placental perfusion model. In contrast, larger particles in the range of hundreds of nanometers are expelled outside. Due to the size restriction of the trophoblast channel, which typically ranges from 15 to 25 nm, it is possible for silver nanoparticles with an average size of around 20 nm to passively enter the placenta through the pericellular pathway, such as diffusion. On the other hand, larger silver nanoparticles may be delivered to the placenta through endocytosis, which can occur via phagocytosis, receptor-mediated or independent mechanisms.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"22 3","pages":"1365 - 1389"},"PeriodicalIF":15.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Dyes are classified according to their origin such as plant, animal, mineral, microbes, and waste; their chemical structure, e.g., indigoid, flavonoid, and tannin dyes; their color; and their application such as mordant dyes and direct dyes. Methods to improve dyeing include sonication, plasma, ultraviolet, microwave, and gamma irradiation. Most bio-based dyes are biodegradable, renewable, non-hazardous, non-allergic, and simple to use. Yet bio-based dyes are limited by poor color fastness and a constrained palette of shades. These limitations can be resolved by using mordants on textile materials.
