Production ecological control is an integral part of the national environmental monitoring system. The article describes the results of production ecological control of impurity of groundwater drawn from wells in the territory of the Tuapse refinery and presents a situational plan of wells layout in the Tuapse refinery. Analysis of groundwater was represented from 2012 to 2016 with their content (mg/l) of oil, phenols, plumbum, chloride, and anionic surfactants. We have revealed the excess of oil products and phenols and developed measures to reduce concentrations of these substances in the groundwater refinery in Tuapse

The flowsheet purification of exhaust gases in the Novocherkassk SDPP after the electrostatic precipitator on I-th stage of purification set group cyclone, on the II-nd stage of purification - baghouse. To determine the particle size distribution of fly ash, we selected ash from the transport network to the group cyclone, and the in a group cyclone, and in a baghouse. With the help of the microscope "Biomed- 3" we produced pictures of ash particles with different magnification. Granulometric composition of three selected ash samples were determined according to the mass content of particles of different grain size, expressed in percent relative to the weight of dry ash sample taken for analysis. For size fractions from 10 mm to 0.5 mm sieve method is applied without rinsing with water, for size fractions less than 0.5 mm sieve method is applied with water washing. The particle size of the ash mixture, taken up before the cyclone,

When combustion of fuel in thermal power plants, combustion products are formed, which contain: fly ash, particles of unburnt pulverized fuel, sulfuric and sulfur dioxide, nitrogen oxide, gaseous products of incomplete combustion, sodium salts, soot particles, calcium dioxide, etc. Getting into the atmosphere, they cause great harm to the components of the biosphere. The article presents a laboratory analysis of industrial emissions into the atmosphere of 1-7 power units for 2015 and 2016 at Novocherkassk State District Power Plant. The components NO2, NO, CO, SO2, C (soot) have been determined. It is established that for the whole observed period of excess of maximum permissible emissions was not revealed. Emissions of each of the components are within the same level and are stable

The content of metals in raw rice is determined. Inversion voltammetry (IVA) was carried out in an accredited laboratory on the "Ta-Lab" device of the company "Tom-Analit" LLC according to the approved method of ERD F 16.1: 2: 2.2: 2.3.46-06. Silicon dioxide is determined according to ERD F 16.1: 2: 2.2: 3.65-10 and humidity according to GOST 5180-2015. Preparation for the IVA is illustrated. Voltammograms of the potential difference of the chloride-silver reference electrode are compared with the current strength of the indicator mercury-film electrode of electrochemical cells. It has been established that the main metals of the raw rice called Regul grown in the Krasnodar region are: copper 1.6 ± 0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5 mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and silicon dioxide 6.5 mg/kg. The presence of iron is associated with the wear of gravity. The content of zinc, manganese and silicon dioxide corresponds to this type of grain. The presence of copper and lead is associated with the absorption of heavy metals from the soil

Groundwater is the source of drinking water in rural areas, it is a part of urban water and it is formed due to the filtering of cross waters in a stratified medium permeable rocks. The impact of anthropogenic factors leads to changes in the qualitative composition of groundwater. The article presents the results of industrial environmental monitoring of ground water refinery of Tuapse in the period from 2012 to 2016 according to its content of ammonium-nitrogen, nitrate-ions, sulphates, formaldehyde, toluene, xylene and ethylbenzene. Analysis of groundwater sampled from wells located at the site of the refinery was conducted by a factory-certified laboratory. The content of the components meet the regulatory indicators. We examine the effects of industrial toxicants on the human body
