ENVIRONMENTAL POLLUTION FROM MICROPLASTICS (MPS), AN ANTHROPOGENICALLY MEDIATED MENACE TO THE BIOSPHERE, IS A GLOBAL CONCERN. THIS RESEARCH CONDUCTED A BIBLIOMETRIC ANALYSIS OF MPS IN SOIL AND TERRESTRIAL ECOSYSTEMS USING R SOFTWARE AND BIBLIOSHINY TO ANALYZE DESCRIPTIVE STATISTICS, AUTHOR CONTRIBUTIONS, DOCUMENTS, AND CONCEPTUAL STRUC-TURES. THE SCOPUS DATABASE WAS SELECTED, AND VARIOUS KEYWORDS OPTIMIZED THE SEARCH. AN ANALYSIS OF RESEARCH TRENDS DIVIDED THE TIMELINE INTO THREE PERIODS: PERIOD I (2012–2018), PERIOD II (2019–2021), AND PERIOD III (2022). RESULTS SHOWED WANG J. AS THE AUTHOR WITH THE HIGHEST H-INDEX, WHILE SCIENCE OF THE TOTAL ENVIRONMENT HAD AN H-INDEX OF 43. IN PERIOD I, RESEARCH FOCUSED ON MPS AND PLASTIC POLLUTION, RAISING QUESTIONS ABOUT THEIR IMPACTS ON TERRESTRIAL ECOSYSTEMS. RESEARCH FOUND THAT MPS NEGATIVELY AFFECTED SOIL ORGANISMS BY DECREASING GROWTH RATES...

The 58% of Peru's population lives in the arid Pacific coastal region and is highly dependent on the availability of Andean snowmelt water, both for human consumption and for power generation and other economic activities. Tropical glaciers are sensitive indicators of climate change, the impact of which has been reflected in the reduction of glacier areas and volumes. In this paper we present an assessment of the deglaciation and glacial record of temperature increase (°C) in the Llanganuco basin (Cordillera Blanca, Peru) since the end of the Little Ice Age (LIA; ~1850). Deglaciation has been evaluated by reconstructing 2D and 3D glacier surfaces; whereas, the increase in air temperature was deduced from the difference in the Altitude of the Equilibrium Lines in each period analyzed (LIA final, 1962 and 2016). From the Little Ice Age - 1962, the area deglaciated was ~13 km 2 (30% reduct...

THE AIM OF THIS BIBLIOMETRIC ANALYSIS WAS TO EVALUATE THE EVOLUTION OF SCIENTIFIC RESEARCH IN HYDROGEN, FOCUSING ON GREEN HYDROGEN PRODUCTION, STORAGE, AND UTILIZATION. ARTICLES FROM PROMINENT DATABASES WERE ANALYZED, REVEALING A STRONG EMPHASIS ON SUSTAINABLE HYDROGEN TECHNOLOGIES THROUGH KEYWORDS LIKE “HYDROGEN PRODUCTION”, “GREEN HYDROGEN”, AND “SOLAR POWER GENERATION”. MATURE RESEARCH AREAS INCLUDE PRODUCTION METHODS AND ELECTROLYSIS, WHILE EMERGING TOPICS SUCH AS ENERGY EFFICIENCY AND POLICY ARE GAINING TRACTION. THE MOST-CITED PAPERS, FROM ENERGY CONVERSION AND MANAGEMENT TO THE INTERNATIONAL JOURNAL OF HYDROGEN ENERGY, COVER TECHNO-ECONOMIC ASSESSMENTS AND CASE STUDIES ON DEPLOYING HYDROGEN TECHNOLOGIES. KEY FINDINGS HIGHLIGHT THE VARIABILITY OF THE LEVELIZED COST OF HYDROGEN (LCOH) ACROSS TECHNOLOGIES AND REGIONS. DEEP LEARNING APPLICATIONS, INCLUDING FAST FOURIER TRA...

THE OBJECTIVE OF THIS RESEARCH WAS TO EVALUATE THE SUSTAINABILITY OF A CO-TREATMENT SYSTEM THAT COMBINES MUNICIPAL WASTEWATER (MW) AND ACID MINE DRAINAGE (AMD) THROUGH THE TECHNIQUE OF INTERMITTENT ELECTROCOAGULATION, APPLIED AS AN ADVANCED SOLUTION TO IMPROVE CONTAMINANT REMOVAL EFFICIENCY AND OPTIMIZE ENERGY BALANCE. FOUR SCENARIOS WERE ANALYZED: TREATMENT I (WITH A 1/7 RATIO OF URBAN WASTEWATER TO AMD), TREATMENT II (WHICH INCLUDES AN ARTIFICIAL WETLAND), TREATMENT IIIA (WHICH INTRODUCES ELECTROCOAGULATION TO ENHANCE SULFATE REMOVAL AND PH REGULATION), AND TREATMENT IIIB (WHICH EMPLOYS A 1/15 RATIO OF AMD TO EUTROPHIC WATER). THE METHODOLOGY FOCUSED ON CALCULATING KEY SUSTAINABILITY INDICATORS SUCH AS THE NET YIELD RATIO (EYR), EMERGY INVERSION RATIO (EIR), ENVIRONMENTAL LOADING RATIO (ELR), AND SUSTAINABILITY INDEX (SI), IN ORDER TO ASSESS THE IMPACT OF EACH TECHNOLOGY ON THE ENERGY ...

This study aimed to bibliometrically analyze the scientific production on pre-Hispanic agricultural technologies, highlighting their potential to address contemporary challenges related to food security and sustainability. To achieve this, 584 documents from SCOPUS (1932–2024) were examined using VOSviewer and CiteSpace, enabling the mapping of co-authorship networks, keywords, and institutional collaborations, as well as reviewing citation indicators, h-index, and gindex. The results indicate a substantial increase in publications since the 1980s, with accelerated growth from the 2000s onward. The United States leads in publication volume, followed by the United Kingdom, China, India, and France. Prominent among the research institutions are multidisciplinary centers specializing in archaeology, ecology, and biotechnology. Influential journals in the field include Journal of Archaeolo...
