- Аннотация: Highlighting the context of soils, we discussed the issues of environmental safety of using a synthetic highly toxic organic substance – heptyl (or unsymmetric dimethylhydrazine, UDMH), carried out a comparative analysis of Russian methods for its identification, characterized the behavior and interaction with ecosystem components, and summarized the existing experience in soil detoxification. Despite the long-term use of UDMH, analytical methods for its determination in soil are far from perfect, have a number of uncertainties and require further improvement, since the possibility of its reverse synthesis from transformation products during sample preparation does not let assess the degree of danger to ecosystems and humans unambiguously and objectively. Environmental pollution by heptyl during normal operation of launch vehicles is currently negligible. However, large amounts of heptyl can enter ecosystems due to launch vehicle accidents. In acidic peat soils (Histosols) at the regular falling sites of the first stages of launch vehicles in the Arkhangelsk region, heptyl pollution persists for at least 10 years. And in alkaline soils (Arenosols, Gypsisols, Solonetz) at the falling sites in the Ulytau region of Kazakhstan, due to rapid evaporation and transformation, it preserves no more than one year. In Russia, the existing soil remediation techniques can be grouped into thermal, sorption, biological, and others, some of which are based on the oxidation of heptyl with the formation of a number of derivatives, the properties and toxicity of which are poorly understood.
