Abstract At VNIINM a facility was created to decontaminate soil and ground. The facility was tested using actual ground contaminated as a result of the CHERNOBYL accident that was brought from the BRYANSK region. At the initial ground contaminated with CS-137 to the degree of 1,6 bq/g the decontamination factor was 4–5. The practicability of the technology used in the facility for ground decontamination via hydroclassification has been demonstrated. The project of a commercial area remediation complex was designed having the throughput > 20 t/h contaminated soil.

Land Clearance

One of the measures to eliminate the consequences of the Chernobyl accident was the exclusion of highly contaminated land from agricultural use. Due to the positive dynamics of the radiation situation, the issue of land return becomes relevant. However, in the period of exclusion of these lands the land clearance degradation processes were developing. The second part of the article is devoted to the issue of economic evaluation of the expediency of land return and the mutual coordination of the results of separate stages of complex ecological and economic evaluation. The research was carried out in Mogilev branch Institute of radiology (Republic of Belarus).

One of the measures to eliminate the consequences of the Chernobyl accident was the exclusion of highly contaminated land from agricultural use. During the natural decay of radionuclides there is a decrease in the activity of 137Cs and 90Sr in the soil. The issue of land return becomes relevant. The article describes the main stages of formation of the system of criteria and indicators of ecological and economic evaluation of the expediency of land return. The first part of the article is devoted to the issue of radiological evalation.

The effect of diatomite and tripoli added into the soil artificially contaminated with benzo[a]pyrene was studied. A decrease in the toxic effect of BaP on barley plants was established when diatomite and tripoli were added as ameliorants to contaminated soil. The improvement of plants grown сharacteristics on soils contaminated with BaP with the addition of diatomite and tripoli was shown up to 2-4 times compare to contaminated samples.

The Impact

As a result of the model experiment, an increase in the enzymatic activity of meadow chernozem of the impact zone of Ataman Lake with the introduction of a strains mixture of metal-resistant microorganisms into the soil was established. The experiment has shown that the application of bacterial strains increases the dehydrogenase activity of contaminated soil by 51.8% compared to the variant without remediation

The Status

This study was conducted in the Khulna metropolitan city to determine the status of noise pollution at major traffic intersections and assess the possible effect of noise on regular noise afflicted people. For this research, five busiest roadways and traffic intersections; two mixed zone and three commercial zones were selected purposively and 'ST-8850 Sound Level Meter' was used to record the noise pressure level. Average noise pressure level and some noise parameters (Leq, L10, L50, L90, and Lnp) were measured at different shifts in each location both on working days and holidays. The result evidently specified that noise level in all major traffic circles of Khulna metropolitan city was much higher than the recommended threshold of acceptable noise level set by the Department of Environment (DOE) of Bangladesh. It was observed that the mixed area (Sonadanga, Gollamari) tends to have a higher average noise level than those of the commercial area (Shibbari, Notunrasta, Dakbangla). The noise pollution level (Lnp) in mixed areas varied from 92.77 dB (A) to 104.74 dB(A) on working days and 86.9 dB(A) to 105.5 dB(A) on holidays. On working days, the highest Leq was observed 92.65 ± 4.15 dB(A) in Sonadanga (mixed area), whereas the lowest was 85.13 ± 2.83 dB(A) in Dakbangla (commercial area). However, on holidays the highest level of Leq was found 90.41 ± 2.25 dB(A) in Sonadanga, while the lowest levels were 80.43 ± 3.20 dB(A) in Dakbangla. One-way ANOVA with LSD post-hoc test results illustrated that on working days there was a significant difference between the noise pollution levels (NPL) in different shifts of day time (F = 8.412, p < .05). The respondents of the study area addressed that they were the most affected by annoyance (70%), headache (62%), and hearing loss (46%) due to regular exposure to the traffic noise. Therefore, it is recommended to enhance awareness regarding the cause and effect of noise pollution among the noise producers and oppressed people. Subsequently, administrative measures have to take to attenuate noise pollution and indemnify the quality health of the citizens.
