Recently, interest has grown in plasma-activated media (PAM) and, in particular, plasma-activated water (PAW) in connection with their extensive applications in medicine, pharmacology, agriculture and the food industry. In this paper, we studied the processes of production of reactive oxygen and nitrogen species (RONS) in distilled water under the influence of cold atmospheric plasma (CAP) generated by a source, based on the use of a piezotrans former. The first results obtained in the study of the UV absorbance spectra in distilled water treated with a direct piezo-discharge showed not only the dependence of the RONS production on the exposure time, but also the long lifetime of these RONS in the treated liquid.
