[1] Surface waters of the Arctic Ocean have the highest concentrations of dissolved organic carbon (DOC) and terrigenous dissolved organic matter (DOM) of all ocean basins. Concentrations of dissolved lignin phenols in polar surface waters are 7-fold to 16-fold higher than those in the Atlantic and Pacific oceans, and stable carbon isotopic compositions of DOM are depleted in C by 1–2% relative...

Colored dissolved organic matter (CDOM) is an important part of aquatic ecosystems and plays a key role in the biogeochemical cycle. In this study, CDOM absorption spectrum curves water quality parameters from 30 sampling sites wetlands Poyang Lake, Jiangxi Province, China, were collected October 2016. The optical characteristics spatial distribution CDOM, correlation between coefficient at wav...

Bile acids increase the proliferative activity of rat colonic epithelium. However, the mechanisms responsible are unknown. The present study examined the relationships between deoxycholate (DOC) induced surface cell sloughing, as measured by loss of DNA into the lumen and by light microscopy, and the subsequent increases in mucosal ornithine decarboxylase activity and [3H]thymidine (dThd) incor...

High-resolution horizontal and vertical distribution of dissolved organic carbon (DOC), chromophoric, fluorescent matter (CDOM FDOM) were investigated in the western boundary current system tropical Northwest Pacific (<200 m) autumn 2017. A strong correlation between DOC stratification index indicated that profile was primarily regulated by physical processes. The association high aCDOM(254) wi...

Heavy metals constitute some of the most dangerous pollutants of water, as they are toxic to humans, animals, and aquatic organisms. These metals are considered to be of major public health concern and, therefore, need to be removed. Adsorption is a common physico-chemical process used to remove heavy metals. Dissolved organic carbon (DOC) and suspended solids (SS) are associated pollutants in ...

Natural organic matter (NOM) in drinking water supplies can provide precursors for disinfectant byproducts, molecules that impact taste and odors, compounds that influence the efficacy of treatment, and other compounds that are a source of energy and carbon for the regrowth of microorganisms during distribution. NOM, measured as dissolved organic carbon (DOC), was monitored daily in the White R...

Peatland ecosystem services include drinking water provision, flood mitigation, habitat provision and carbon sequestration. Dissolved organic carbon (DOC) removal is a key treatment process for the supply of potable water downstream from peat-dominated catchments. A transition from peat-forming Sphagnum moss to vascular plants has been observed in peatlands degraded by (a) land management, (b) ...

Abstract Purpose The aims of the study were to investigate interaction between fractions organic matter and polycyclic aromatic hydrocarbons (PAHs) in bottom sediments use mussels as passive biomonitors consensus-based sediment quality guidelines for ecological risk assessment sediments. Methods Bottom samples taken from 46 points located Ro?nów reservoir (Poland). (SOM) characteristics include...

Direct Capillary Nanofiltration (Direct CNF) is a new technique used for surface water and wastewater treatment in one step without pre-treatment. The CNF membrane module combines the favourable cleaning properties of capillary ultrafiltration membranes with the favourable separation properties of nanofiltration membranes in terms of removal of DOC, colour, bacteria, viruses and pesticides.
