Use of high-energy ionizing radiation for microbiological decontamination of coastal soil in the Kolubara river basin, Serbia
The Kolubara river pollutes the coastal land in the river basin and makes it unsuitable for agricultural activities in that area. Also, contaminated land poses a risk to the environment. Different methods can be used for soil decontamination. These methods include biological treatment/biore...

| description | The Kolubara river pollutes the coastal land in the river basin and makes it
unsuitable for agricultural activities in that area. Also, contaminated
land poses a risk to the environment. Different methods can be used for
soil decontamination. These methods include biological treatment/bioremediation, chemical oxidation, soil stabilization, physical
methods, such as soil leaching, or treatment with high-energy ionizing
radiation. Gamma irradiation of soil is a well-known method of inhibiting
microbial activity. This paper investigated the influence of different doses
and dose rates of gamma irradiation on microorganisms' decontamination of
coastal soil, in the Kolubara river basin. The irradiation effects on
reducing the total number of microorganisms and removing mold and pathogenic
bacteria from soil samples were examined. Gamma radiation affects the
soil's organic matter, causing the formation of free reactive radicals,
which act as reducing and oxidizing agents, cleaving C-C bonds, and
depolymerizing carbohydrates. It was found that a dose of 3 kGy of gamma
radiation, neutralizes all pathogenic bacteria, a dose of 5 kGy
deactivates mold in soil samples, and a dose of 10 kGy is optimal to kill
all microorganisms in the samples and sterilize exposed soil. The research
showed that the dose rate does not significantly affect microbiological
decontamination of soil using gamma irradiation. The content of heavy metals
in soil was determined, and the obtained values were compared with the
remediation limit values prescribed by the regulations. It was concluded
that the content of heavy metals in the analyzed soil samples is below the
limit of remediation values. The only exception is the slightly increased
copper content in one sample. The result of this research is the conclusion
that the coastal land from the Kolubara basin can be decontaminated by gamma
radiation treatment. This advanced soil treatment technology is available in
Serbia because there is an industrial plant for gamma radiation treatment
within the Vinča Institute. |
