Methods of control and monitoring of organophosphorus compounds in natural environments while organophosphorus compounds (OPCs – Vx) utilization are proposed. It was found that environmental control standards and quality standards of natural environments were not exceeded. Environmental control was carried out as a planned control of pollutant sources (emissions, discharges, process waters, waste and reaction masses), while environmental monitoring analyzed the main objects of the natural environment (atmospheric air, soil cover, natural and groundwater, snow cover) was carried out. The volume of eco-analytical studies conducted within the framework of environmental control and monitoring amounted to 200 plots and objects of control and monitoring, more than 250 indicators. Natural water, groundwater, snow cover were monitored according to 57 indicators, atmospheric air – for 10 indicators, soil cover, bottom sediments – for 11 indicators. Summary data of the state environmental control and monitoring in 2006–2009 during the period of utilization of organophosphorus compounds (FOS – Vx) are presented. The methodological base of eco-analytical support for the utilization of FOS has been supplemented and implemented, 14 methods for the determination of phosphorus-containing substances – O-isobutylmethylphosphonate, methylphosphonic acid, their total content (the indicator “total phosphorus”) were developed and adapted. The development of methods is based on the justification of the ranges of determined concentrations, taking into account the technological parameters of the disposal processes, experimental justification of sampling, sample preparation and analytical termination on target substances. These methods were tested on real control and monitoring objects and certified in accordance with the established procedure. The OPCs disposal process was carried out normally. No OPCs and their degradation products were detected in environmental objects during the entire observation period, and no negative environmental effect was established.
