The Effects of Hurricanes and Storms on the Composition of Dissolved Organic Matter in a Southeastern U.S. Estuary

Frontiers in Marine Science, 2022
Extreme events such as hurricanes and tropical storms often result in large fluxes of dissolved organic carbon (DOC) to estuaries. Precipitation associated with tropical storms may be increasing in the southeastern U.S., which can potentially impact ...

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Rapid Down‐Slope Transport of Fresh Dissolved Organic Matter to the Deep Ocean in the Eastern North Atlantic

Geophysical Research Letters
Intense convective mixing in the central North Atlantic is a major gateway for dissolved organic matter (DOM) into the deep ocean, sustaining elevated dissolved organic carbon (DOC) concentrations.

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

How the Physical and Chemical Properties Affect the Heavy Metal Content in Surface Water in Different Types of Peatlands

Land Degradation &Development, EarlyView.
ABSTRACT Only ~3% of the global land surface is covered by peatlands, yet more than one‐third of global soil carbon is stored in these ecosystems and contaminant filtration can be provided. The extent to which peat humification (Fibric–Hemic–Sapric) is linked to dissolved heavy metals in peatland surface waters has remained poorly quantified at a ...

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Variation in riverine inputs affect dissolved organic matter characteristics throughout the estuarine gradient

Frontiers in Marine Science, 2016
Terrestrial dissolved organic matter (DOM) undergoes significant changes during the estuarine transport from river mouths to the open sea. These include transformations and degradation by biological and chemical processes, but also the production of ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...
