Distribution pattern of dissolved organic matter in pore water of sediments from three typical areas of western Lake Taihu and its environmental implications

Water Science and Technology, 2023
The migration, transformation, and accumulation of dissolved organic matter (DOM) in pore water of sediment cores play a pivotal role in lacustrine carbon cycling.

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 ...

Dissolved organic matter in soils varies across a chronosequence of Pinus massoniana plantations

Ecosphere, 2017
Stand age plays a significant role in forest ecosystems nutrient cycling. Unfortunately, less attention was accorded to the changes in dissolved organic matter (DOM) in soil layers of mono‐stand plantations. A field soil sampling experiment was conducted

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

Environmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The

Tracing inputs of terrestrial high molecular weight dissolved organic matter within the Baltic Sea ecosystem [PDF]

Biogeosciences, 2012
To test the hypothesis whether high molecular weight dissolved organic matter (HMW-DOM) in a high latitude marginal sea is dominated by terrestrial derived matter, 10 stations were sampled along the salinity gradient of the central and northern Baltic ...

Biodegradation of Dissolved Organic Matter (DOM) Released from Phytoplankton in Lake Biwa

Analytical Sciences, 2012
The biodegradation study of algal dissolved organic matter (DOM) released from Microcystis aeruginosa, Staurastrum dorsidentiferum and Cryptomonas ovata was carried out. The algal DOM released from Microcystis aeruginosa and Staurastrum dorsidentiferum is relatively stable, while a part of the algal DOM released from Cryptomonas ovata may be easily ...

Bioaccessibility of Metal(loid)s From Anthropogenic Contamination in Dry Riverbed Sediments in the Cartagena–La Unión Mining District (Murcia, SE Spain): Implications for Human Health Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the contamination levels, bioaccessibility, and potential health risks of As, Cd, Cu, Pb, and Zn in sediments from three dry riverbeds (El Beal‐EB, Las Matildes‐LM, and Ponce‐PN) impacted by historical mining activities in the Cartagena‐La Unión Mining District.

Changes in Dissolved Organic Matter (DOM) Fluorescence in Proglacial Antarctic Streams [PDF]

Arctic, Antarctic, and Alpine Research, 2013
Abstract Dissolved organic matter (DOM) exported in glacier meltwater influences downstream biogeochemical processes, and climate warming may increase the meltwater DOM flux. In this study, we quantify and use fluorescence spectroscopy and parallel factor analysis (PARAFAC) to characterize DOM exported in glacier meltwater in Taylor and Wright Valleys,

Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

Journal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Working‐Class Muscles? Co‐Operative Gyms in Interwar Britain

History, EarlyView.
Abstract The Health & Strength League's network of co‐operative gymnasiums constituted one of interwar Britain's most significant yet overlooked physical culture institutions, affiliating over 800 gyms across Britain and Ireland by 1939. Drawing on Health & Strength magazine's editorial content and reader contributions, this article argues that these ...
