Low temperature atmospheric pressure plasmas (LTPs) together with advanced oxidation processes (AOPs) are alternative to conventional chemical methods of soil decontamination. The processing of soil itself depends on several factors, like type of soil and pollutants, treatment technique, geological and atmospheric circumstances. In the paper problems of soil, water, buildings, farms, land, and housing contaminations after floods and ecological disasters have been introduced. Plasma aided techniques together with AOPs have been presented from the point of view of decontamination potential as well as their impact on soil properties and fertility. Additionally, nanosize biological phenomena occurring in DNA strands during ozonation were visualized. The reaction of ozone with DNA is essential to understand the sterilization in agricultural soil. The structural images of the DNA samples were taken with the atomic force microscopy (AFM). It was shown that highly concentrated ozone broke hydrogen bonding of nuclei bases of DNA in relatively short time.
