Traditional testing for toxicity was (and in part is) usually based on mortality of the test-organisms.
The measure of the hazard of the chemical is usually the increase in mortality.
The most popular measure is the LC50, the concentration that leads to the death of 50% of test animals.
This tool to assess the potential toxicity of the chemical is most popular, but... is it perfect?
New approach:
A number of publications was published that developed a much more subtle method for assessing the environmental hazards of chemical pollutants in aquatic environment.
This method is measuring the effect of the chemical tested on functional activity of the test-organisms. The organisms do not die in these experiments. The concentrations of the chemicals tested are sublethal (in other words, the concentrations are far less than the lethal concentrations). It is important that the functional activity is of vital importance to the entire ecosystem. As a result, the decrease in this functional activity of the organism has a very negative impact on the ecosystem. It means that the sublethal effect of the chemical is really of some environmental hazard.
In this series of publications, the test-organisms were bivalve mollusks and some other aquatic invertebrates that filter water. The chemicals that were tested were synthetic surfactants (synonyms: surface-active substances, surface-active agents) or the mixtures of chemicals that included surfactants (detergents). The functional activity that was measured was water filtration by these aquatic invertebrate animals. The vital importance of this functional activity of invertebrates is the role of water filtration as a component of a very important function of the healthy ecosystem, water self-purification (functioning of the ecosystems toward maintaining and improving water quality in aqautic habitats).
The series of new facts was discovered in these publications.
These facts are:
Synthetic surfactants and detergents inhibited water filtration by marine and freshwater bivalve mollusks [1-12];
Synthetic surfactant inhibited water filtration by rotifers [13];
Synthetic surfactant inhibited water filtration by daphnia [14].
The significant role of water filtration as a component of the vital function of healthy aquatic ecosystems (as a component of the functioning of the ecosystems toward water self-purification) was described and analized in the papers [ 15-20 ] and the book [ 12 ]. As a result, a consistent theory of multifunctional biotic self-purification of water was formulated [15-20].
As a result of this series of experiments and there analysis, a better understanding of ecosystems was achieved. It helped formulate a better, modernized definition of the scientific term 'ecosystem' [21].
Moreover, the new better understanding of aquatic ecosystems helped develop a new approach to solution of the problem of eutrophication [22].
Another application of the results of this series of publications was developing principles for aquatic biodiversity conservation in nature reserves for water objects and water habitats [23].
