The objective of the present study was to investigate effects cadmium-zinc (Cd-Zn) interactions on their uptake, oxidative damage cell macromolecules (lipids, proteins, DNA) and activities antioxidative enzymes in tobacco seedlings as well roots leaves adult plants. Seedlings plants were exposed Cd (10 µM 15 µM) Zn (25 50 combinations or with either 25 Zn). Measurement metal accumulation exhibited that had mostly positive effect uptake seedlings, while antagonistic roots. According examined...

Lichens serve as effective bioindicators for air pollution studies, yet most biomonitoring research focuses primarily on the distance from sources, often neglecting wind data that could elucidate spread of airborne pollutants. In our previous study in Slavonski Brod, Croatia, we utilized a monitoring station, emphasizing impact meteorological conditions, particularly wind, dispersal pollutants neighbouring oil refinery. To gain deeper understanding dynamics, here, studied lichen...

Plastic contamination has become one of the most pressing environmental issues due to rapidly increasing production disposable plastic products, their fragmentation into smaller pieces, and long persistence in environment, which affects all living organisms, including plants. In this study, Allium cepa roots were exposed 0.01, 0.1, 1 g L−1 commercial polystyrene (PS-MPs) polymethyl methacrylate microparticles (PMMA-MPs) for 72 h. Dynamic light scattering (DLS) analyses showed high stability...

Abstract Increased use of radio and microwave frequencies requires investigations their effects on living organisms. Duckweed ( Lemna minor L.) has been commonly used as a model plant for environmental monitoring. In the present study, duckweed growth peroxidase activity was evaluated after exposure in Gigahertz Transversal Electromagnetic (GTEM) cell to electric fields 400, 900, 1900 MHz. The plants exposed 2 h 23 V/m field 900 MHz significantly decreased comparison with control, while an...

Silver nanoparticles (AgNPs) are the most exploited nanomaterial in agriculture and food production, their release into environment raises concern about impact on plants. Since AgNPs prone to biotransformation, various surface coatings used enhance stability, which may modulate AgNP-imposed toxic effects. In this study, of stabilized with different (citrate, polyvinylpyrrolidone (PVP), cetyltrimethylammonium bromide (CTAB)) AgNO3 photosynthesis tobacco plants as well AgNP stability exposure...

One of the key factors affecting plant survival and agricultural yield production is temperature. The magnitude temperature extremes increasing as a result global climate change. present study evaluated impact elevated treatments on Brassica rapa seed germination, well prolonged exposure seedlings to temperatures 37 °C short-term 45 °C. Elevated reduced germination rate affected pattern. Both applied heat stresses negatively seedling development root growth, showed differential physiological...

We investigated interactions between copper (in the concentrations of 2.5 μmol L-1 and 5 L-1) cadmium (5 in common duckweed (Lemna minor L.) by exposing it to either metal or their combinations for four seven days. Their uptake increased with time, but was lower plants treated metals than given alone. In separate treatments, malondialdehyde (MDA) level catalase peroxidase activity. Both induced DNA damage, did only after 7 days treatment. On day 4, combination additionally MDA as well...

Rising temperatures and pronounced drought are significantly affecting biodiversity worldwide reducing yields quality of Brassica crops. To elucidate the mechanisms tolerance, 33 kale accessions (B. oleracea var. acephala) were evaluated for individual (osmotic elevated temperature stress) combined stress + temperature). Using root growth, biomass proline content as reliable markers, responses. Four representatives selected further investigation (photosynthetic performance, biochemical sugar...

Exposure of different animal species to radiofrequency electromagnetic fields (RF-EMF) could cause various biological effects such as oxidative stress, genotoxic and dysfunction the immune system. However, there are a lack results on stress response genotoxicity in honey bee (Apis mellifera) after exposure RF-EMF. This study was performed investigate RF-EMF activity catalase, superoxide dismutase, glutathione S-transferase, lipid peroxidation level DNA damage larvae. Honey larvae were...
