TWO ASPECTS IN ASSESSING THE QUALITY OF GEOCHEMICAL INFORMATION
Abstract
The main purpose of the research is to improve the quality of geochemical information by developing and applying effective methods of analyzing the quality of data on the chemical composition of environmental objects. Two phases-types are highlighted in geochemical quality assessment methods: 1. The quality of geochemical information formation and the assessment of errors at various stages of its receipt (testing, analysis of chemical composition, storage and transmission of information, ways of interpreting the results, etc.). Assessment of the quality of geochemical information to address geoecological environmental problems and pollution of natural and anthropogenic objects. International control experiments have shown that real errors far exceed the values regulated by the guidelines; there has been a permanence of the regional level of error for many decades and the reproducibility of definitions is close in size to quantitative and approximate-quantitative methods of micronutrient analysis. The article examines the methodology and shows the high effectiveness of assessing the quality of geochemical information for geoecological tasks using the method of total pollution indicator.
