Inhibitory analysis of top-down control: new keys to studying eutrophication, algal blooms, and water self-purification

SA Ostroumov - Hydrobiologia, 2002 - Springer;
Top-down control is an important type of interspecies interactions in food webs. It is
especially important for aquatic ecosystems. Phytoplankton grazers contribute to the top-
down control of phytoplankton populations. The paper is focused on the role of benthic filter;

Abstract: Quaternary ammonium compounds (QACs) are cationic surfactants that are widely
used as disinfectants. In the present study, we tested two important representatives, namely,
benzalkonium chloride (BAC) and dimethyldioctadecyl-ammonium bromide (DDAB) in four

Analytics of surfactants in the environment: problems and challenges

E Olkowska, Z Polkowska, J Namiesnik - Chemical Reviews, 2011 - ACS Publications
We give a general classification of SAAs (with examples of the structural formulas of
selected compounds) and of their toxicity to living organisms. Next, we review the problems
posed by the analysis of surfactants in environmental samples and the analytical techniques

Magnetic removal of surfactants from wastewater using micrometric iron oxide powders

CC Borghi, M Fabbri, M Fiorini, M Mancini… - Separation and …, 2011 - Elsevier
The aim of this paper is the study of a sustainable process for the treatment of urban
wastewater able to reduce surfactant concentrations close to the back-ground levels or, at
least, lower than the values allowed by law for a reuse in agriculture. The considered

Self-stratifying antimicrobial polyurethane coatings

MB Yagci, S Bolca, JPA Heuts, W Ming… - Progress in Organic …, 2011 - Elsevier
In this work antimicrobial polyurethane coatings were prepared aiming at self-stratification. A
hydroxyl end-capped liquid oligoester consisting of three equimolar diacids and an excess
of 1, 4-butanediol has been synthesized by a condensation reaction. A set of quaternary

Tolerance of an aquatic macrophyte Potamogeton crispus L. to sodium dodecyl sulphate

EA Solomonova, SA Ostroumov - Moscow University Biological Sciences …, 2007 - Springer
Abstract The effects of the anionic surfactant sodium dodecyl suplphate on the aquatic
macrophyte Potamogeton crispus L. are studied. Concentrations of 83–133 mg/l caused
fragmentation of the stems of plants. The tolerance of the plants to the negative effects of the

Decreasing the measurable concentrations of Cu, Zn, Cd, and Pb in the water of the experimental systems containing Ceratophyllum demersum: The …

SA Ostroumov, TV Shestakova - Doklady Biological Sciences, 2009 - Springer
10 Distinct signs of worsening; the shoots are dead or dying The leaves have detached from
the stems. There is a mucous film on the wa ter surface. The phytomass has sunk to the
bottom part of the water column; the upper part of the water column, free of plants, is 1–2 cm

Adsorbent biopolymers from tannin extracts for water treatment

J Sánchez-Martín, J Beltrán-Heredia… - Chemical Engineering …, 2011 - Elsevier
Up to four tannin extracts from different natural vegetal sources were gelified with
formaldehyde and acetaldehyde. The feasible combinations were tested in the removal of
Zn2+, methylene blue (MB) and cetyltrimethylammonium bromide (CTAB) in aqueous

A solid phase extraction–ion chromatography with conductivity detection procedure for determining cationic surfactants in surface water samples

E Olkowska, Ż Polkowska, J Namieśnik - Talanta, 2013 - Elsevier
Abstract A new analytical procedure for the simultaneous determination of individual cationic
surfactants (alkyl benzyl dimethyl ammonium chlorides) in surface water samples has been
developed. We describe this methodology for the first time: it involves the application of solid

Accelerated decrease in surfactant concentration in the water of a microcosm in the presence of plants: innovations for phytotechnology

EV Lazareva, SA Ostroumov - Doklady Biological Sciences, 2009 - Springer;
MATERIALS AND METHODS We used the macrophytes that proved suitable in previous
experiments and displayed a high viability and resistance to surfactants (these plants will be
described in detail elsewhere). Plastic flasks 1.5 l in volume each containing 1 l of settled tap
