The allowable ranges of the values criteria for ecological and economic assessment of living standards are considered. The authors have conducted comparative characteristic of quality of tomatoes, fruits and seeds of melons. The qualitative analysis of used water for irrigation was made. This condition guarantees quantity and quality of the crop, which is closely interrelated with health security issues. The proposed admissible limits scale featured 4 gradations (minimum; neutral; middle and maximum). The practical appliance of Nanodiagnostic method for identifying product quality in agriculture, based on the methodology "Shammas", ensures the effective environmental and economic assessment of value and quality of life. The duration of express method is less than 30 minutes, and it is conducted on molecular genetic level, which is a proof of universality of proposed nanoinstrumentarium.
