The control in the express mode status of the water used in sustainable agribusiness

Abstract

The permanent worsening of the water bodies’ ecological condition has been observed in the modern world. The pollution by different toxic matters occurs with the shore of the water body itself as well as the water. Not to allow the rise of the dangerous situations for people, mass death the inhabitants of the rivers and lakes and agricultural crops (under irrigation, etc.) the permanent control of the water condition is necessary. The identify centers of pollution allows a set of measures to clean up and prevent further contamination of the time.

The only objective and effective control is the manual probe sampling. But the capacity for the probes amount of such a sampling is limited. Moreover, the hardware for the taken probes complete analyzing is basically situated in the stationary laboratories and costs very much. Therefore it is desirable to be tasked for the investigation by the gages that include constituting a danger polluting products.

To save the moneys and the time and to manage to take steps in time, the efficient on-site expresscontrol of the taken probes is necessary. In this situation, an inexpensive simple to operate transportable cross functional measuring instrument could become a solution for this problem. Especially there are many problems in the research of the state of agricultural fields. These fields can extend over tens km with the presence of only dirt roads. A portable nuclear-magnetic relaxometer developed by us is one of such instruments. The only criterion of its use is the existence of the sufficient amount of the nuclei with the magnetic moments in the investigated fluid.

The service of the instrument is based on that fact that the parameters of every fluid that allow to diagnose its aggregate state change (the temperature rise and the appearance of other saluted or not matters in it) instantaneously are the longitudinal T1 and transverse T2 relaxation times. The size of the magnetic system were matched in such a way that the instrument could be easily transferred “manually”. The amount of the investigated matter doesn’t exceed 15 gram. In this case, the temperature of the liquid fluid in the container will grade up to the temperature of the environment, where the container itself has been situated for a long time, within 10-15 seconds. Therefore, the liquid fluid temperature can be measured with high accuracy and also controlled without problems.

The use of this tool will facilitate the ecological monitoring of water bodies and plants, using proven solid state physics, experimental techniques, in fact, increase its efficiency, environmental quality and reproducibility.
