Important tasks of ecological-geochemical research are both industrial disaster aftermath evaluations and their prevention, which can be solved exclusively on a basis of technologies that are capable of: 1) effectively detect weak (low contrast) geochemical anomalies, 2) introduce high-precision monitoring, 3) reliable prognosis of ecological hazards in order to take early preventive steps that will impede threshold limit value excess in the future. This paper presents research technique for weak industrial geochemical anomalies for sediments with variable lithological composition (soils). Influence of sediment types variations on the geochemical background is leveled by means of instrumental determination of trace, major elements content in sediments and their modal mineralogical composition. Trace elements content in main components of sedimentary matrix (detrital, organic etc.) can be calculated nn this basis as well as individual background concentration level for each sample. Suggested approach can be used as a basis for new technologies of timely detection, precision monitoring and reliable prognosis of further evolution of ecologically hazardous industrial geochemical anomalies.
