Chemical speciation of inorganic pollutants in river–estuary–sea water systems

Environmental Monitoring and Assessment, 2008
Monitoring studies and thermodynamic modeling were used to reveal the changes of inorganic chemical species of some water pollutants (nutrients and trace metals such as Fe, Mn, Zn, Cu, Cd and Pb) inthe river-estuary-sea water system. The case studies were two rivers, Kamchiya and Ropotamo, representing part of the Bulgarian Black Sea water catchment ...

ASSESSMENT OF CHEMICAL POLLUTION OF THE SURFACE WATER IN VLADIMIR

Lomonosov Geography Journal
The results of studies of river water of the Vladimir city district for the content of heavy metals conducted in August 2022 are presented and the anionic-cationic composition of water is analyzed. It is shown that a number of heavy metals (lead, iron, cadmium, zinc, copper and vanadium) and ions (ammonium, magnesium, sulfates, nitrates, fluorides ...

MSThunder: A deep learning-based nontargeted analytical framework for the accurate and rapid identification of unknown organic pollutants in water

Environmental Chemistry and Ecotoxicology
Nontargeted analysis (NTA) has emerged as a crucial technology for identifying unknown organic pollutants in water. However, current NTA methods commonly omit or misjudge the pollutants due to the low-accuracy and efficiency in the structural prediction ...

Synthesis of Cyclodextrin-functionalized Cellulose Nanofibril Aerogel as a Highly Effective Adsorbent for Phenol Pollutant Removal

BioResources, 2015
Cellulose nanofibril (CNF) aerogels with grafted beta-cyclodextrin (β-CD) were prepared for the adsorption of phenol pollutants from water. Compared with regular wood fibers, CNF aerogel not only can immobilize more β-CDs, but also it provides higher ...

BIOACCUMULATION OF LIPID – SOLUBLE POLLUTANTS IN AQUATIC SYSTEMS [PDF]

Croatian Journal of Fisheries, 1999
One of the major problems of water pollution is the capability of pollutants to concentrate in aquatic organisms. Bioaccumulation and bioconcentration of such chemicals in fish render it unsuitable for human consumption.

Causes of coastal waters pollution with nutrients, chemicals and plastics worldwide

Marine Pollution Bulletin
Worldwide, coastal waters contain pollutants such as nutrients, plastics, and chemicals. Rivers export those pollutants, but their sources are not well studied. Our study aims to quantify river exports of nutrients, chemicals, and plastics to coastal waters by source and sub-basin worldwide.
