Investigation of impact of rocket fuel components on the condition of scotch pine

The object of the study was the Scotch pine, as a bioindicator of soil contamination from the storage area of MCT (rocket fuel components) and missile military units. It has been established that the radiation levels (exposure and equivalent dose of external gamma radiation, alpha and beta-field levels, specific activity of radionuclides, including technogenic cesium-137) at the facility correspond to background indicators. According to the indications of the mili- tary chemical reconnaissance device, the content of MCT in the individual test sites is 0.001 mg / l, which corresponds to the level of “Danger”. On the soil in special facilities there are visible traces of spills of technical fluids, and in the air there is a specific smell. Chemically contaminated fittings, construction debris, remnants of containers and special structures are in abandoned condition. In this connection, reclamation of the given territory is required. When carrying out work on detoxification and rehabilitation of soils, it is necessary to take into account the pronounced spatial unevenness of the level of residual contamination. To calculate the volume and technology of the work, it is recom- mended to carry out a microbiological soil analysis and make a detailed map of phytotoxicity. When compiling a phyto- toxicity map, the following set of indicators are recommended to be taken into account: interest and quality concerning exposed to necrosis and chlorosis of the samples of pine needles.
