“…Lepidium sativum L. is an edible plant which aqueous extracts have been used in the medicine. Therefore, its use in the soil reclamation processes may be doubtful due to the risk of transferring pollutants to the food chain . The risk for human is limited by the exclusion of highly contaminated sites from agricultural use, and by the monitoring of potential pathways of spreading pollutants .…”

This study focuses on the physiological response of Lepidium sativum L. to Hg and/or nitrilotriacetic acid (NTA) during soil reclamation. Greenhouse experiments are conducted in soil contaminated with Hg to final concentrations of 10 or 100 mg kg−1. The influence of Hg and NTA is studied on the growth of L. sativum L. and the activation of its non‐enzymatic antioxidant system, including generation of ascorbic acid (AA) and tocopherols (TOCs). The results shows that Hg is accumulated by L. sativum L. in its aboveground tissues, but increased lipid peroxidation and H2O2 formation in the plant shoots, which is a symptom of oxidative stress. Plants exposed to Hg produced increasing amounts of AA and TOCs to protect their cells from oxidative damage. Application of NTA to polluted soil did not show any toxic effects on L. sativum L. growth or physiological processes. Amendment of polluted soil with NTA significantly increased Hg accumulation in the aerial tissues of L. sativum L., resulting in decreased soil contamination. The use of NTA can therefore be considered for use in assisted phytoextraction of Hg contaminated soil.

“…Activation of BPOD is aimed at Н 2 О 2 destruction and counteracting oxidative stress caused by C. ohridella attack. It is shown that changes in physiological processes of plant leaves under adverse conditions, particularly photosynthesis correlates with peroxidase activity (Kim et al, 2010;Smolinska, 2017). This enzyme destroys ROS and protects chloroplasts from damage.…”

The search for promising plants with bactericidal and fungicidal activity is of great interest for practical and veterinary medicine, This article reveals the high antibacterial effect of the use of ethanol extracts from 8 species of plants of the families Anacardiaceae (Cotinus coggygria Scop., Rhus typhina L., Rhus trilobata Nutt. and Toxicodendron orientale Greene), Araliaceae (Hedera helix Linnaeus and Aralia elata (Miq.) Seem.), Phyllanthaceae (Leptopus chinensis (Bunge) Pojark.), Berberidaceae (Mahonia aquifolium (Pursh) Nutt.) against 23 strains of bacteria and one strain of fungi. The in vitro experiment revealed the zone of inhibition of growth of colonies exceeding 8 mm during the application of ethanol extracts of C. coggygria against twelve species of microorganisms (Enterococcus faecalis, Escherichia coli, Staphylococcus aureus, S. epidermidis, Bacillus cereus, Listeria ivanovi, Corynebacterium xerosis, Rhodococcus equi, Proteus vulgaris, P. mirabilis, Serratia marcescens and Candida albicans), Rhus typhina – against twelve species (E. faecalis, E. coli, S. aureus, S. epidermidis, L. ivanovi, C. xerosis, Rh. equi, P. vulgaris, Salmonella typhimurium, S. adobraco, S. marcescens and C. albicans), Rhus trilobata – against fourteen (E. faecalis, E. сoli, S. аureus, S. epidermidis, B. subtilis, B. cereus, L. ivanovi, C. xerosis, Rh. equi, P. vulgaris, P. mirabilis, Рseudomonas аeruginosa, Yersinia enterocolitica and C. albicans), Toxicodendron orientale – against eleven (E. faecalis, S. аureus, L. іnnocua, C. xerosis, Campylobacter jejuni, Rh. equi, P. vulgaris, P. mirabilis, Р. аeruginosa and C. albicans), Hedera helix – against seven (S. аureus, S. epidermidis, L. monocytogenes, C. jejuni, Rh. equi, P. vulgaris and C. albicans), Aralia elata – against nine (E. coli, S. aureus, B. cereus, C. xerosis, P. vulgaris, P. mirabilis, S. typhimurium, S. marcescens and C. albicans), Leptopus chinensis – only against four (E. coli, S. epidermidis, B. cereus and P. mirabilis) and Mahonia aquifolium – against only three species (S. epidermidis, C. jejuni and P. vulgaris). As a result of the research, the most promising for studying in future regarding in vivo antibacterial activity were determined to be C. coggygria, Rhus typhina, R. trilobata, Toxicodendron orientale and Aralia elata.

Aim: Plastics, and acid rain, are the results of the anthropogenic activities; although, the injuries caused by acidic precipitation to plants are well known, what happen if acid rain is coupled with microplastics pollution? Methods: In this experiment, we simulated, under controlled condition, a contaminated area from four different kinds of Microplastics (MPs): Polyethylene (PE), Polyvinylchloride (PVC), commercial mixture (PE + PVC) and Polypropylene (PP) subjected to acidic precipitation on Lepidium sativum, both in short then long exposures. At the end of experimentation were analysed: i) plant biometrical parameters (percentage inhibition of seed germination, plant height, leaf number and fresh biomass productions); and ii) oxidative stress (e.g., levels of hydrogen peroxide, glutathione, and ascorbic acid). On plant subjected to long exposure are quantified also: lipidic peroxidation through Malondialdehyde (MDA) concentration, Aminolevulinic Acid (AlA), pigments (Chl-a, Chl-b, carotenoids) and soluble sugars. Results: Our results suggest that root system is more sensitive to MPs coupled with acid rain then above ground biomass. Furthermore, in short exposure toxicity begin with PE+ treatments to shift towards PVC+ toxicity in long exposure at radical level. Conclusion: Our experiment demonstrates that different kinds of microplastics supplied with acid rain are able to interfere in different ways both in short and in long exposure, but also at shoot and root levels, on garden cress.
