METHOD FOR MONITORING ECOLOGY OF OBJECTS USED FOR ELIMINATION OF CHEMICAL WEAPONS Russian patent published in 2007 - IPC G01N31/00 G01N33/18 G01N33/24 

FIELD: environmental control, possible use at chemical weaponry elimination objects for estimating their influence on ecological situation in the region.

SUBSTANCE: first variant of the method for monitoring ecology of objects used for elimination of chemical weapons includes taking samples of surface, soil and underground water, snow cover, bottom sedimentations, soil, analyzing samples and processing the data, recording the results into analytical database, on basis of processing of analysis data, ecological situation is estimated in the region of object for storage and elimination of chemical weapons, in sanitary and protection zone and zone of protective measures, samples of atmospheric air are additionally taken, monitoring of flora and fauna in the region of chemical weaponry elimination object, in sanitary and protection zone, in protective measures zone is performed, all samples are compared to standards of maximal allowed concentrations of each certain substance, in case of exceeded maximal concentration in the air, analysis of water is performed, if maximal concentration in water is exceeded, analysis of soil is performed, if maximal concentration in soil is exceeded, fauna and flora is analyzed in the region of chemical weaponry elimination object, in sanitary and protection zone, in protective measures zone, as a result of comparison of resulting data, schedule of analysis operations is tightened, namely, times of analysis set in accordance to standards, while A≤(maximal allowed concentration)·α is considered a condition of normal environmental influence of an object, where A - result of analysis of samples of certain substance, α - maximal allowed concentration excess tolerance coefficient. In accordance to second variant, when the solution is determined before beginning construction of chemical weaponry elimination objects, in advance before construction of chemical weaponry elimination object is started, background monitoring is performed on territory assigned for construction of object, which monitoring includes taking samples of surface, soil and underground water, snow cover, bottom sedimentations, soils, and also samples of atmospheric air are additionally taken, and monitoring of flora and fauna is performed in the region of construction of chemical weaponry elimination object, in sanitary and protection zone, in protective measures zone, and after that the data resulting from background monitoring is compared to data, received in process of elimination of chemical weaponry, all samples are compared to standard maximal allowed concentrations of each certain substance, if maximal allowed concentration is exceeded in the air, analysis of the water is performed, if maximal allowed concentration is exceeded in the water, analysis of the soil is performed, if maximal allowed concentration is exceeded in the soil, analysis of flora and fauna is performed in the region of chemical weaponry elimination object, in sanitary and protection zone, in protective measures zone, as a result of comparison of received data, schedule of analysis operations is tightened, namely, analysis times set in accordance with standard times, processing of sample analysis data includes comparison of received data to background monitoring data, and as condition of normal environmental influence of object, following is considered: where A - result of analysis of samples of certain substance, Φ - result of background monitoring, δ < 0,1-0,2.

EFFECT: production of trustworthy estimate, possible prediction of influence of chemical weaponry elimination object on environment for operative making of decisions concerning possible emergency.
