METHOD OF ESTIMATING CONDITION OF WATER SOURCE IN AN AGRICULTURAL ENTERPRISE EFFLUENT ZONE Russian patent published in 2005 - IPC

FIELD: environmental monitoring.

SUBSTANCE: invention relates to hygiene and sanitary of freshwater reservoirs and is meant to be used for microbiological testing of condition of water source in an agricultural enterprise effluent zone, in particular in the effluent zone of poultry factories and pig-breeding farms. For this aim, water is sampled at least in two zones: in the effluent zone of agricultural enterprise and in the zone, where influence of agricultural enterprise effluent over different periods is excluded. Then, contents of ammonia compounds and enzymatic activities of urease-carbamidamidohydrolase in samples are measured. Obtained data are processed: contents of ammonia compounds and enzymatic activities in different samples are compared to each other and dynamic of changes in data in samples taken from different zones are compared.

EFFECT: enabled quick testing at high accuracy in estimations and minimized labor and means involved.
