New broad picture of the fundamental role of biological filtering in self-purification (and self-bioremediation, self-organization, as well as stability) of aquatic ecosystems
http://5bio5.blogspot.com/2012/08/new-broad-picture-of-fundamental-role.htmlIt is the first paper in which a synthesis of both author's new experimental data and international literature was made, which led to a new broad picture of the fundamental role of biological filtering in self-purification ( and self-bioremediation, self-organization, as well as stability) of aquatic ecosystems.

According to one of approaches to the definition of criteria for the phenomenon of life, the key attribute
is the ability of the life system for some self-regulating and self-supporting. Part of such holistic
functions of aquatic ecosystems as self-regulating and self-supporting is their cleaning the water via a
multitude of various mechanisms. The goal of this paper is to present some fundamental elements of
the theory of ecosystem self-purification (water self-purification) which emphasizes the importance of
the four functional biological filters that are instrumental in purification and upgrading the quality of
water in aquatic ecosystems. These functional filters are: (1) direct water filtering by aquatic organisms
that are filter-feeders; (2) the filter (represented mainly by communities of aquatic plants/periphyton)
which prevents input of pollutants and biogenic elements (N, P) from land into water bodies and water
streams; (3) the filter (represented by benthic organisms) which prevents re-entry of pollutants and
biogenic elements from the bottom sediments into the water; (4) the filter (represented by
microorganisms attached to particles which are suspended in the water) that provides microbiological
treatment of the water column. New experimental data by the author reveal the negative role of manmade
effects on the ecological machinery which purifies water. The analysis and discussion lead to the
holistic theory of the natural process of bioremediation of aquatic ecosystems.
