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.

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

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

Response of dissolved organic matter characteristics to nitrogen addition in a boreal peatland of Northeast China

Ecological Indicators, 2023
Boreal peatlands, a crucial stock of dissolved organic matter (DOM), are susceptible to increased reactive nitrogen (N) inputs. However, the response of DOM characteristics to elevated N availability in these ecosystems is still obscure.

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 ...

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 ...

Dose–Response Effect of Glucagon on Glucose, Beta‐Cell Secretion and Metabolism in Healthy Individuals

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aim Glucagon is a key regulator of glucose and energy metabolism, yet the dose–response effects of glucagon on markers of metabolism in humans are not fully characterised. We investigated the dose‐dependent effects of glucagon on glucose metabolism, β‐cell secretion and markers of hepatic metabolism in healthy adults.

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,

Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

Journal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers
