Three LM samples were treated and tested as OCs for CLC. The results demonstrated that pure LMs exhibited poor regeneration ability and combustion efficiencies of less than or equal to 50 % at the tenth cycle, making them unsuitable as standalone OCs. However, given their diverse yet advantageous elemental composition, LMs were explored as potential supports for iron ore (IO) by substituting 50 % of IO with LMs. The performance of the resulting EIO (LM:IO = 1:1) samples demonstrated that EIO1 and EIO2 performed comparably to IO with average syngas combustion efficiencies of approximately 70 % for IO, EIO1, and EIO2. While EIO3 outperformed IO, exhibiting an increasing trend over 10 cycles with high CO and H<sub>2</sub> combustion efficiencies of 78.95 % and 85.01 %, respectively. The increasing trend was attributed to the presence of CaO and brownmillerite, unique to EIO3. Incorporating LMs into IO maintained or improved sintering resistance of the OCs. Characterizations of the OCs elucidated the transformations occurring during CLC and their impact on reactivity, physical properties, and overall performance. While pure LMs are unsuitable as OCs due to poor regeneration capabilities, their alkaline earth metal (AEM) content makes them effective as supports for IO.

Increasing evidence suggests that environmental exposures-both chemical and biological-play a critical but under-recognized role in the etiology of undernutrition in children under five years of age. This scoping review synthesizes evidence from studies published between January 2014 and March 2024 on the individual and combined effects of exposure to environmental chemical and biological hazards on undernutrition outcomes in early childhood. We reviewed peer-reviewed literature examining associations between exposure to metals (e.g., lead, cadmium), air pollutants (e.g., particulate matter with a diameter of 2.5 micrometers or less (PM<sub>2.5)</sub>, carbon monoxide), natural toxins (e.g., aflatoxins), and infectious agents (e.g., malaria parasites, helminths) and undernutrition markers such as stunting, wasting, underweight, and anaemia in children under five. Prenatal and early-life exposure to heavy metals and air pollutants was consistently associated with impaired growth, stunting, and anaemia. Aflatoxin exposure was linked to growth suppression, while malaria and helminth infections were associated with wasting and anaemia, especially in sub-Saharan Africa and Asia. Despite the biological plausibility of synergistic or additive effects, few studies have assessed the impact of co-exposure to multiple environmental hazards on childhood undernutrition. Undernutrition in children is influenced not only by diet and infection but also by environmental exposures that disrupt nutrient utilization and growth. The limited number of studies addressing combined exposures highlights a critical research gap. Addressing childhood undernutrition requires a multisectoral approach that integrates nutrition, environmental health, WASH (water, sanitation, and hygiene), pollution control, and public health education. Nutritional interventions alone are insufficient unless environmental risk factors are simultaneously addressed.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"122815"},"PeriodicalIF":7.7,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058197","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}

Recognizing that changes in renal function indicators are critical markers for diagnosing and grading CKD and other kidney diseases, this meta-analysis aims to assess the associations of ambient air pollution with key renal function indicators. A comprehensive search up to September 27, 2024, was conducted across four databases (i.e., PubMed, Web of Science, Scopus, and Embase). Eligible studies were required to report the associations of ambient particulate matter (PM<sub>1</sub>, PM<sub>2.5</sub>, PM<sub>10</sub>), nitrogen dioxide (NO<sub>2</sub>), ozone (O<sub>3</sub>), sulfur dioxide (SO<sub>2</sub>), carbon monoxide (CO) with key renal function indicators (including eGFR, estimated glomerular filtration rate; SCr, serum creatinine; BUN, blood urea nitrogen; UA, uric acid; CysC, cystatin C) and to provide quantitative estimates of these associations. The primary meta-analyses were conducted involving 32 studies with adults (n = 3,022,895) as participants. Long-term PM<sub>2.5</sub>, PM<sub>10</sub>, and NO<sub>2</sub> exposures were linked to decreased eGFR, with pooled percent changes of -0.90% (95%CI: -1.71%, -0.08%), -1.05% (95%CI: -1.67%, -0.42%), and -0.43% (95%CI: -0.78%, -0.08%) every 10 μg/m<sup>3</sup> increase in these air pollutants, respectively.
