[Ecological monitoring in agro-ecological systems]

The fundamental principles of the ecologic monitoring in the antropogenic ecosystems are dealt with. Analyzed are the structure and function of the agroecologic systems, and, on the basis of the particular aspects established a concept is developed of the ecologic control at autoecologic and biocoenologic level. An analysis is likewise made of the ecologic sequelae resulting from the chemical war launched by the American aggressors in Vietnam and the specific trends therefrom in the substantiation of the ecologic monitoring. Stated is the necessity of profound investigations to establish the bioaccumulation of dioxine, a poisonous agent which was contained in herbicides and defoliants used in the war, and which was distinguished by exclusively high toxicity, producing teratogenic and cancerogenic effects and possessing high resistance in the environment.
