Для многих учебных курсов и лекций полезный факт: содержание ДДТ и метаболитов в жире печени трески (рыбий жир) 0,038 мг/кг, а в жире печени макроруса 0,071 мг/кг. Правда, могу успокоить — это меньше, чем допустимый уровень 0,2 мг/кг. Содержание полихлорированных бифенилов в печени трески 0,679 мг/кг при допустимом уровне 3 мг/кг. Правда в биологически-активных добавках (БАД) из жира печени трески найдено уже пообольше ДДТ -1,4 мг/кг, а в БАД из...
готовятся к размещению учебно-методические материалы по вопросам экологии и экотоксикологии, а также по междисциплинарным вопросам, связанным с биосферой. Так или иначе этои материалы будут по тематике связаны с нашей научной работой.
Возможно, этот сайт будет объединен с другим нашим сайтом - по вопросам совершенствования образования в области экологии и наук об окр среде и биосферы.
Если есть пожелания — просим их...

Detergents to poison water, to ruin climate? This material is related to the publication: www.springerlink.com/content/7166067538534421/ [Ostroumov S.А., Widdows J. Inhibition of mussel suspension feeding by surfactants of three classes // Hydrobiologia. 2006. Vol. 556, No. 1. P. 381 – 386. — DOI 10.1007/s10750-005-1200-7] Until now, the list of the most dangerous environmental pollutants did not include the large group of chemicals which are called surfactants. Those chemicals produce foams. They are the key components of detergents, shampoos, foams for bath, and many other commercial products. They are also used in case of oil spills. Traditionally they are considered as symbol of hygiene, of cleanness and purity, of washing and removal of dirt, which...
Ostroumov S. A. The effect of synthetic surfactants on the hydrobiological mechanisms of water self-purification. - Water Resources. 2004. Volume 31, Number 5, p. 502-510. ISSN 0097-8078 (Print) 1608-344X (Online). DOI 10.1023/B:WARE.0000041919.77628.8d.

Long-term studies of the biological effect of surfactants, including the effect surfactants exert on filter feeders, are reviewed. The role of filter feeders in the functioning of freshwater and marine ecosystems is analyzed. New aspects in the assessment of...

Ostroumov S.А., Widdows J. Inhibition of mussel suspension feeding by surfactants of three classes // Hydrobiologia. 2006. Vol. 556, No. 1. P. 381 – 386. Effects of SDS, TDTMA, and Triton X-100 on M. edulis and M. edulis / M. galloprovincialis. Inhibitory effects of three surfactants on the filtration rates by marine mussels were described and studied. The xenobiotics tested represented anionic, cationic and non-ionic surfactants (tetradecyltrimethylammonium bromide, a representative of a class of cationic surfactants; sodium dodecyl sulphate, a representative of anionic alkyl sulfates; and Triton X-100, a representative of non-ionic hydroxyethylated alkyl phenols). All three surfactants inhibited the clearance rates. The significance of the results for the ecology of marine...
