UnknownConstruction and demolition waste recycling in developing cities: management and cost analysis.
In Bolivia, construction and demolition waste (CDW) is unmanaged. The current research implemented a CDW flow analysis and a cost assessment in the city of La Paz, aiming to compare future recycling scenarios. Lack of data is challenging; therefore, a review of 31 international studies has been cond...

UnknownDe novo assembly and functional annotation of Myrciaria dubia fruit transcriptome reveals multiple metabolic pathways for L-ascorbic acid biosynthesis.

Background

Myrciaria dubia is an Amazonian fruit shrub that produces numerous bioactive phytochemicals, but is best known by its high L-ascorbic acid (AsA) content in fruits. Pronounced variation in AsA content has been observed both within and among individuals, but the genetic factors resp...

UnknownRare Earth Elements and Technology-Related Trace Metals in Paediatric Scalp Hair: A 2001 Urban Baseline from Spain.
Rare earth elements (REEs) and technology-related trace elements are increasingly used in modern products and processes, but biomonitoring data in healthy children and adolescents remain scarce; scalp hair provides a practical, integrative matrix for assessing multi-element patterns over time. Scalp...

UnknownRelationship between lipid accumulation product and oxidative biomarkers by gender in adults from Yucatan, Mexico.
Excessive adipose tissue can lead to metabolic abnormalities resulting in lipid alteration and oxidative stress (OS) status. The lipid accumulation product (LAP) index is a biomarker that indicates central lipid accumulation and has been proposed as an accurate and independent indicator of risk for ...

UnknownShallow magmatic intrusion evolution below La Palma before and during the 2021 eruption.
La Palma, Canary Islands, underwent volcanic unrest which culminated in its largest historical eruption. We study this unrest along 2021 using Interferometric Synthetic Aperture Radar (InSAR) and a new improved interpretation methodology, comparing achieved results with the crustal structure. We rep...

UnknownHuman health risk assessment of PM10-bound heavy metals and PAHs around the Latin America's Largest opencast coal mine.
Air pollution in opencast coal mine areas is a critical issue, resulting in harmful severe effects on human health. Therefore, it is essential to understand the air pollution factors and to assess the risks to humans. This study evaluated the potential risks (carcinogen and non-carcinogen) of inhala...

UnknownContribution of calcium in drinking water from a South American country to dietary calcium intake.

Objective

To describe the calcium concentration of tap and bottled waters from Argentina and to estimate the contribution of drinking water to calcium recommendations.

Results

Calcium concentrations provided by water authorities ranged from 6 to 105 mg/L. The mean calcium level of sam...

UnknownDetection of volcanic unrest onset in La Palma, Canary Islands, evolution and implications.
La Palma island is one of the highest potential risks in the volcanic archipelago of the Canaries and therefore it is important to carry out an in-depth study to define its state of unrest. This has been accomplished through the use of satellite radar observations and an original state-of-the-art in...

UnknownAnalysis of PM<sub>10</sub> trends in open-pit mining: Assessing emission controls and WHO guideline compliance.
This study evaluated the concentrations, trends, and variability of PM10 particulate matter in two Air Quality Monitoring Systems (CorpoGuajira's_AQMS and Cerrejón's_AQMS) in an open-pit coal mine in northeastern Colombia from 2010 to 2020. Additionally, different levels of emission contr...

UnknownThe ephemeral fumarolic mineralization of the 2021 Tajogaite volcanic eruption (La Palma, Canary Islands, Spain).
The present work aims to characterize the ephemeral mineral assemblage related to the fumarolic fields of the Tajogaite volcano, formed in 2021 in La Palma Island (Canary Islands, Spain). A set of 73 samples was obtained after two sampling campaigns in different fumarole sectors of the studied area....
