Lischyk A. The ecotoxicology assessment of danger fluorine in dependence in soil-climatic zones at application of mineral fertilizers

Object of research - biogeochemical behavior of fluorine in agroecosystems of different soil-climatic zones of Ukraine under influence natural and anthropogenic factors. The purpose of examination consist in carrying out ecotoxicology of an assessment of fluorine by results of study its biogeochemical features of behavior in agroecosystems of different nature-climatic zones of Ukraine, in dependence on genesis of soils and influence of mineral fertilizers. Methods of research: field, laboratory, statistical. Scientific novelty of received results: features of allocation of fluorine in different phylum's of soils Ukraine in dependence on their genesis for the first time are explored, the influence of long-lived application of mineral fertilizers to processes of accumulation and migration of fluorine in these soils is established, the influence of irrigation to this processes. By results of examinations the assessment of danger of fluorine is lead ecotoxicology. The methodical approaches to ecotoxicologyof a regulation of mineral fertilizers behind the content of fluorine with allowance for of background content in soils, permissible concentration, stability of soils contamination by this device for the first time designed. The calculations of permissible contents of fluorine in phosphorites of deposits of Ukraine are lead. A new view of domestic phosphoric fertilizing agrophoska on a subject of contamination agroecosystems by relative frame bonds of fluorine for the first time is studied at application of the given view of fertilizing under a winter wheat. The methodical approaches to a regulation of phosphoric fertilizing behind the content of fluorine are expedient for utilizing at carrying out of ecological examination of new views agrochemical, which is stipulated by the Law of Ukraine " About pesticides and agrochemical " (1996). Results of work utilized at drawing up of the methodical recommendations " Procedure аgroecological of an assessment of mineral fertilizers ", surveyed and approved on section of agriculture and effecting of products plant-management NTP of the Minаgropolitics of Ukraine (protocol №14 from October 13, 2003), Scientific advice of Institute аgroecological and biotechnology UAAS (protocol №8 from October 01, 2003).
