Studied the issues of the water quality suitable for consumption in some mountainous regions of Lviv region, in particular in Skolivsky, Turkivsky, and Starosambirsky districts. The obtained results based on the main hydrochemical indicators show the water quality meets the requirements for the degree of pollution of the hygienic classification of water objects. The conditions for the habitat of hydrobionts and terrestrial biota are normal. Most water samples have a weakly alkaline reaction, indicating a possible high content of hydrocarbonates. Concerning the hardness, all studied samples are soft and medium hard water types. The value of total alkalinity of water samples ranges from 1.8 to 6.1 mmol/m 3 , which corresponds to the physiological integrity of the composition of drinking water. Sulphate ions and chloride ions are present in almost all natural waters, their content is mainly due to chemical weathering with sedimentary rocks during oxidation of sulfides, dissolution of sulfur-containing and chlorine-containing minerals.It has been investigated the sequence between hardness of water and non-infectious diseases in the studied regions. Constant consumption of such water may cause a danger to the population suffering from cardiovascular disease, blood congestion, myocardial infarction.
Hybrid conduct, efficiency and rapidity of hostilities depend on many factors, including the ability to constantly receive information from the battlefield, time to make decisions and clear implementation of tasks. This can be achieved by increasing the efficiency of all types of reconnaissance, including chemical. The article substantiates the prospects of using unmanned aerial vehicles to detect chemical contamination during chemical reconnaissance by radiation, chemical and biological reconnaissance units. It is established that the probability of detecting a chemical situation depends on the degree of training, physical endurance, psychological stability and fatigue of reconnaissance patrol personnel, technical characteristics of devices installed on reconnaissance vehicles, speed of reconnaissance vehicle or pedestrian patrol in hard-to-reach places. The capabilities of radiation, chemical and biological reconnaissance units to quickly detect chemical conditions are significantly enhanced by conducting air reconnaissance by unmanned aerial vehicles and equipping ground and air reconnaissance devices with devices that identify both combat poisons and hazardous chemicals. It is shown that the use of UAVs with a set of passive infrared spectrometry and automated real-time data transmission system is currently the best option, as the probability of detecting war poisons (hazardous chemicals) in a given area increases, and time for chemical reconnaissance - decreases, which, accordingly, increases the response time of units to a chemical threat. To install modern chemical reconnaissance equipment, in particular passive Fourier-ICS devices, helicopter-type UAVs must meet the following requirements: length - up to 5 m, weight of useful equipment - up to 50 kg, cruising speed - 150 km / h. In addition, it decreases moral exhaustion and the risk of personnel damage. The probable order of application of unmanned aerial vehicles of helicopter type equipped with modern devices is given.
