Conclusion

radioisotopes, the researcher, while avoiding these minor problems, loses also
the great advantages, which their use brings, because they open fascinating
possibilities for the investigation and understanding of natural processes. It
was understood long ago that only the holistic approach in the study of aquatic
ecosystems leads to understanding their functional organization, and this very
knuwledge can characterize the ecosystem's "health" and predict possible
changes under anthropogenic impacts. It is now quite evident also that the
holistic approach can be realized in practice only on condition of a wide use
of radioisotopic methods. I shall be satisfied if this book can help in their introduction in all laboratories or institutions studying the aquatic environment.
