Engineering an Enzymatically Active Granular Matrix for On‐Chip Modeling of Bone‐Like Mineralization

Small, EarlyView.
Alkaline phosphatase (ALP)‐functionalized poly(ethylene glycol) (PEG) microgels assemble into a perfusable granular matrix for cell‐free modeling of bone‐like mineralization. Microgel‐associated enzymatic activity promotes calcium phosphate deposition, producing a calcium‐deficient, poorly crystalline apatite‐like phase, while keeping interparticle ...

Characterization and spatiotemporal variations of fluorescent dissolved organic matter in leachate from old landfill-derived incineration residues and incombustible waste.

PLoS ONE
Dissolved organic matter (DOM) influences the bioavailability and behavior of trace metals and other pollutants in landfill leachate. This research characterized fluorescent dissolved organic matter (FDOM) in leachate from an old landfill in Japan during

Achieving sustainable and durable concrete using high‐volume SiO2: Engineering properties, environmental and economic benefits

Structural Concrete, EarlyView.
Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Biological Treatment of Leachate using Sequencing Batch Reactor

Journal of Tropical Forestry and Environment, 2014
In Sri Lanka municipal solid waste is generally disposed in poorly managed open dumps which lack liner systems and leachate collection systems. Rain water percolates through the waste layers to produce leachate which drains in to ground water and finally

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

Genetic and systemic disruption by a municipal solid waste leachate in aquatic and terrestrial models, and human cancer risk assessment of the leachate’s metallic constituents

Discover Toxicology
Solid waste leachate can contaminate soil, surface, and ground waters, posing public and environmental health risks. This study intends to determine cytogenotoxicity of leachate (1–50%, v/v, leachate/tap water) from Lapite waste dumpsite in Ibadan ...

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

The 5T Paradox of Triclosan: From Toiletries to Toxic Trash, a Growing Threat to Humanity

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) persists as a contaminant of concern in the Anthropocene, despite regulatory actions. Environmental dissemination continues through wastewater effluents, biosolid application, and improper disposal practices. This narrative review synthesizes current evidence regarding triclosan's environmental fate, transformation pathways ...
