Ecological Systems and Devices Annotation << Back NANOTECHNOLOGIES IN THE GEOINFORMATION MONITORING V.F. Krapivin, V.Yu. Soldatov, I.I. Potapov An analysis of the problem of using the nanotechnologies for the solution of environmental monitoring tasks is realized. Specifi c achievements and weakness are marked concerning the investigations in this area. Different nanomaterials are characterized to be used in the monitoring systems and to solve the many problems. Perspective tasks are shown a solution of which can rise the effectiveness of the geoinformation monitoring systems. It is marked that using the nano-scale materials in the environmental monitoring systems provide the most precise analysis of many gas and liquid pollutants of the environment with more precise probability of their detection. It is shown that using the nano-particles from gold, silver and iron for the synthesis of sensors owing to their electronics, optical, catalytic and thermal properties provides the functions of detection of mercury in the soil, water and fi sh with high precision. Magnetic nano-particles of iron oxide when their use in the monitoring systems provide the detection functions of pollutants of the water and air. Metal oxides such as titan dioxide are used widely in the sensors for the detection of pesticides, organic colorants and phenols in the water as well as of methane, nitrogen oxides and carbon in the air.
