Heavy metals are most common soil pollutants, including agricultural land. At the same time, the level of heavy metal pollution can significantly exceed the standards. Pea (Pisum sativum L.) and wheat (Triticum aestivum L.) are most important crops. At the same time, no comparative analysis of their resistance to high concentrations of heavy metals has been carried out. In connection with this, the resistance of T. aestivum and P. sativum seedlings to the chronic effects of lead and copper salts in the range of lethal concentrations for T. aestivum was comparatively evaluated (0.15, 0.30 and 0.60 g/L of copper sulfate; 0.5, 1.0 and 1.5 g/L of lead nitrate) in experimental conditions. All studied concentrations of the toxicants caused a decrease in seed germination of T. aestivum relative to the control by 19–38% and 23–58% when exposed to lead nitrate and copper sulphate, respectively, which indicated the manifestation of lethal effects. All studied concentrations of both toxicants caused a significant reduction in the root system length (from 69% to 25 times) and shoot height (by 25–76%) as compared with the control level in T. aestuvum seedlings, and also led to an increase in the intensity of lipid peroxidation in seedling shoots, indicating the development of a stress reaction. At the same time, the studied concentrations of heavy metal salts, which were lethal for T. aestivum, did not cause almost any disturbances of the studied parameters in P. sativum, except for a decrease in the root system length after lead nitrate exposure. Thus, seed germination, growth processes of the root system and shoot, as well as peroxide homeostasis in P. sativum seedlings were much more resistant to the studied concentrations of lead nitrate and copper sulfate as compared with these parameters of T. aestivum.

A family of fifteen quaternary ammonium salts (QAs), bearing the 1,2-bis(4-pyridyl)ethane core, were obtained using for the first time two different green methods, such as microwave (MW) and ultrasounds (US) irradiation, with very good yields and in much shorter times compared to the classical method, and an assay on their antimicrobial action against Escherichia coli (E. coli) was carried out. While 12 to 24 hours were required for complete alkylation of 1,2-bis(4-pyridyl)ethane by reactive halogenated derivatives in anhydrous solvent under reflux conditions, MW and US irradiation reduced the reaction time and the desired products were achieved in a few min. One of the aims of this study was to evaluate the antibacterial potential of the synthesized QAs against pathogenic bacteria, along with their impact on germination activity of wheat seeds (Triticum aestivum L.). The antibacterial activity of the QAs against Escherichia coli was explored by determining the minimum inhibitory concentration (MIC). The MIC values varied from 0.312 to 2.5 mg/mL, highlighting the lowest values attained for the derivatives containing methoxy, chlorine and benzofurane functional groups. The viability of aerobic bacteria was determined with the Tetrazolium/Formazan Test, a method that was found to be the best alternative approach with respect to the difuzimetric method. Seeds of Triticum aestivum L. were used for the evaluation of the germination indicators, such as seed germination (SG), the relative seed germination (RSG), the relative radicle growth (RRG), and the seed germination index (GI). The toxicity studies of QAs 1, 4 and 7, at two different concentrations, showed no inhibitory effect on seed germination.
