[en] The ways of utilization of aluminium industrial wastes by several methods were found. Composition of aluminium industrial wastes was studied. Three ways of utilization of aluminium industrial wastes are proposed. Optimal conditions of utilization of sulphates from liquid and solid sludges were defined.

[en] The comprehensive sensory, analytic-chemical, physical-chemical and microbiological analyzes of numerous water samples taken from upper and lower layers of the largest rivers of Azerbaijan - Kur and Araz were carried out. Sources of the anthropogenic emissions polluting these cross-border rivers are defined. The dose rate of ionizing radiation in nearby territories along the watercourse of these rivers and on minerals of water samples was measured and the levels of all types of ionizing radiation were estimated.

[en] The Middlesex Municipal Landfill (MML) Site is a former municipal landfill in Middlesex, New Jersey that operated between approximately 1940 and 1974; it is currently part of FUSRAP. Because of the lack of waste management regulations at the time, unregulated disposal of municipal and industrial waste occurred, including the acceptance of radioactively contaminated soils from the Middlesex Sampling Plant (MSP) that were used as cover material on the northwest side of the landfill. The radioactive MSP contaminated soils are described as 'FUSRAP-related materials.' In some areas of the landfill, FUSRAP-related material exists comingled with other non-FUSRAP radioactive waste (such as an antique radio-luminescent marker and concrete construction material with elevated gamma readings). However, in other areas of the landfill (specifically the street's right-of-way, called Pershing Avenue, which borders the landfill), non-FUSRAP material is isolated. Several lines of evidence and statistical tools were used to differentiate FUSRAP-related materials from non-FUSRAP-related material, including Z-Score analysis, Tukey-Kramer Honestly Significant Difference test, box-and-whisker plots, Wilcoxon Signed Rank test, and Principal Component Analysis.

[en] Full text:Radiation safety issues of Heydar Aliyev Deep Water Jacket Plant are investigated in three years. For this purpose, an import and export goods, the area of soil and water samples taken from the analysis of radionuclide composition, activity, and concentration of radon gas spectrometric analysis was carried out. Radionuclide composition of the samples have been studied and categorized according to the allocation of radio nuclides the degree of contamination for the purpose of analyzes have been carried out by means of gamma-spectra inertia. Compliance with the requirements of radiation safety of the plant employees, and the restriction of people's living environment, natural radionuclide pollution control planning of radiation during treatment of industrial wastes, as well as the radiation-hygienic requirements of the industrial wastes in order to determine the natural radionuclide content of the effective specific activity (Aeff) not included in the classification.

[en] The main water-bearing and long-term rivers of Azerbaijan (the Kur and Araz) originate from mountain tops of Turkey, flowing on border or across the territory of other countries arrive on the territory of Azerbaijan, intercrossing on the Sabirabad district and flowing further in one stream passing the Neftchalinsky delta flow into the Caspian Sea. These rivers can be polluted from both adjacent territories and by the emission of toxic industrial wastes into small rivers flowing into these transcontinental rivers. Pollution of these rivers can increase many times in the event of natural disasters due to the entry of industrial reagents or waste. Therefore, there is a need for carrying out radiation, chemical and bacteriological monitoring, for taking samples of water and bottom sediments from these rivers for the purpose of carrying out complex organoleptic, physical-chemical and microbiological analyses. These analyses of the taken samples water and bottom sediments in August month 2016 shortly are described below. The dose rate from the natural radioactive background were detected in the surrounding Araz landscape in the territory of the Nakhchivan AR varies in the range 0.03-0.08 μSv/h and the α radiation intensity is within 0-0.11 Bq_eq/sm², in the territory of the Beylagan and Imishli regions varies in the range 0.03-0.04 μSv/h and the α radiation intensity is 0 Bq_eq/sm². The concentration of the 22Na and 40K isotopes in the stream of the Araz river along the territory of the Nakhchivan AR varies in intervals 0.26-0.58 Bq/l.The concentration of the 22Na and 40K isotopes in the stream of the Araz river along the territory of the Beylagan and Imishli regions varies in intervals 0.18-0.38 Bq/l. The concentration of the 22Na and 40K isotopes in the stream of the Kur river along the territory of the Mingachevir-Sabirabad regions varies in the intervals 0.1-0.2 Bq/l. Contamination by organic emissions of the Kur river when it reaches the territory of the Azerbaijan and its further contamination from territory of regions of Azerbaycan were detected.Contamination by organic and inorganic emissions of the Araz river when it reaches the territory of the Sadarak region of Nakhchivan AR and its further contamination through parts of the territory of neighboring countries, located between the Ordubad region and Beylagan district were detected.There are no production enterprises on the sites in the territory of IIR bordering with the territory from Nakhchivan AR and the small rivers flowing alongside the central production regions of Armenia merge into the Araz river. Therefore, it can be concluded that in both cases (before Sadarak and after Ordubad districts) the Araz River is polluted from the Armenian territories.The water samples taken from Araz and Rivers do not meet the requirements of the AZS 282 standard for drinking water.

[en] An electrolytic reactor, combined with an ultrasonic field provides higher ion-transfer conditions during electrolysis by breaking up the barrier layer at the electrode, thus enabling metal to be removed efficiently from dilute solution. It was observed that the energy cost reduced to half compared to general electrolysis. The use of sonication as an agitating medium proved much more effective for the removal of chromium at very dilute concentrations (100 mg/l), compared with less dilute concentrations (500 mg/l). The energy consumption also decreased with increasing chromium concentration. The rate of chromium deposition and current efficiency values for mesh cathode were higher than that for plate cathode, while mesh cathodes consumed less energy than plate cathode irrespective the presence or absence of ultrasonic field. These results show that by applying this ultrasonic technique the beneficial effects of increased deposition rates can be achieved from dilute solutions an in this way, the stringent environmental irregularities can be overcome.
