AB  - In this study, cold atmospheric plasma (CAP) was explored as a novel advanced oxidation process (AOP) for water decontamination. Samples with high concentration aqueous solutions of Diclofenac sodium (DCF) and 4-Chlorobenzoic acid (pCBA) were treated by plasma systems. Atmospheric pressure plasma jets (APPJs) with a 1 pin-electrode and multi-needle electrodes (3 pins) configurations were used. The plasma generated using argon as working gas was touching a stationary liquid surface in the case of pin electrode-APPJ while for multi-needle electrodes-APPJ the liquid sample was flowing during treatment. In both configurations, a commercial RF power supply was used for plasma ignition. Measurement of electrical signals enabled precise determination of power delivered from the plasma to the sample. The optical emission spectroscopy (OES) of plasma confirmed the appearance of excited reactive species in the plasma, such as hydroxyl radicals and atomic oxygen which are considered to be key reactive species in AOPs for the degradation of organic pollutants. Treatments were conducted with two different volumes (5 mL and 250 mL) of contaminated water samples. The data acquired allowed calculation of degradation efficiency and energy yield for both plasma sources. When treated with pin-APPJ, almost complete degradation of 5 mL DCF occurred in 1 min with the initial concentration of 25 mg/L and 50 mg/L, whereas 5 mL pCBA almost degraded in 10 min at the initial concentration of 25 mg/L and 40 mg/L. The treatment results with multi-needle electrodes system confirmed that DCF almost completely degraded in 30 min and pCBA degraded about 24 % in 50 min. The maximum calculated energy yield for 50 % removal was 6465 mg/kWh after treatment of 250 mL of DCF aqueous solution utilizing the plasma recirculation technique. The measurements also provided an insight to the kinetics of DCF and pCBA degradation. Degradation products and pathways for DCF were determined using LC-MS measurements.

AB  - The atmospheric pressure plasmas (APPs) are known to be rich in Reactive Oxygen and Nitrogen Species (RONS) and this rich chemistry is responsible for triggering of cell mechanisms in case of plant or human/animal cells. We can divide this influence in two groups: (1) RONS in gas phase; (2) RONS in liquid phase. Therefore, in order to better understand the reasons for triggered mechanisms and outcomes (better germination percentage and speed, breakout of dormancy, creation of embryos etc.) we need to know and be able to tailor the plasma chemistry both in gas and liquid phase. We have used several APPs for gas phase treatments of plant cells and also for production of Plasma Activated Water (PAW) in order to investigate the influence of liquid RONS chemistry on plant cells. Here we will present different APP sources that are used for production of PAW used for seed imbibition in germination process and direct treatment of meristematic plant cells. Dielectric Barrier Discharge type of APPJ was used for production of PAW, while the plasma needle type was used for direct treatment of meristematic plant cells. The main idea was to check if plasma treatments can be used as for breaking of dormancy and trigger mechanisms in cells even in a normally non-permissive conditions.

AB  - The population growth together with constant climate changes represent a serious challenge for humankind. Additionally, the usage of the pesticides have created adverse effect on environment,
which in return impact even more agricultural production. In order to comply with the demands and
to adapt to the new conditions the farmers need to change or upgrade existing practices by employing
new technologies. As being a promising tools in application in medicine, non-thermal (cold) plasmas
(NTPs) are seen as a green alternative to conventional fertilizers in agriculture to improve yields,
increase size and robustness of plants and to reduce (or eliminate) the need for pesticides [1, 2].
NTPs have rich chemistry of Reactive Oxygen and Nitrogen Species (RONS) that are formed in gas
phase and, in case of water treatment, in gas/liquid interface in liquid [2, 3]. We can use NTPs in
direct treatments of seeds or plant cells where samples are in contact with plasma gas phase chemistry
or indirectly when treated water is applied to the biological samples. In both cases RONS (short or
long-living) are responsible for triggering various mechanisms and effects in plant cells. To better
understand the reasons for triggered mechanisms and outcomes (better germination percentage and
speed, breakout of dormancy, creation of embryos etc.) it is important to characterize the plasma
chemistry both in gas and liquid phase. We have used several atmospheric pressure plasma systems
in treatments of seeds and plant cells in order to investigate the mechanisms responsible for better
germination in seeds, enzyme response and formation of somatic embryos in non-permissive
conditions. The mechanisms investigated were linked with the chemistry of RONS created in gas
phase and/or deposited in liquid phase. Thus, we were able to acquire the data that can be used in
optimization of plasma treatment processes.
