The emergence of polyvinyl chloride (PVC) microplastics (MPs) as pollutants in agricultural soils is increasingly alarming, presenting significant toxic threats to soil ecosystems. Ajwain (Trachyspermum ammi L.), a plant medicinal and culinary value, subjected environmental stressors that threaten its growth productivity. This situation particularly acute given the well-documented toxicity chromium (Cr), which has been shown adversely affect biomass escalate risks productivity such economically therapeutically important species. present study was conducted investigate individual effects different levels PVC−MPs (0, 2, 4 mg L−1) Cr 150, 300 kg−1) on various aspects growth. Specifically, we examined biomass, photosynthetic pigments, gas exchange attributes, oxidative stress responses, antioxidant compound activity (both enzymatic nonenzymatic), gene expression, sugar content, nutritional status, organic acid exudation, accumulation parts L.) seedlings, were also exposed varying titanium dioxide (TiO2) nanoparticles (NPs) 25, 50 µg mL−1). Results from showed increasing significantly decreased sugars, contents roots shoots plants. Conversely, increased indicators term malondialdehyde, hydrogen peroxide, electrolyte leakage, exudation pattern T. seedlings. Interestingly, application TiO2−NPs counteracted leading greater biomass. protective effect facilitated by NPs' ability sequester reactive oxygen species, thereby reducing lowering concentrations both Our research findings indicated enhance resilience seedlings toxicity, not only improved but healthier physiological state demonstrated more balanced acids, critical response mechanism metal stress.

Comparative toxicity of copper and zinc contaminated wastewater irrigation on growth, physiology, and mineral absorption of wheat

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(1)

Published: Jan. 1, 2025

Abstract A comparative pot study was performed to assess the toxic effects of copper (Cu) and/or zinc (Zn) contaminated wastewater (WW) irrigation on growth, physiology, and element concentration wheat grown for two months. The treatments included with uncontaminated as control, Cu‐contaminated WW (CuWW), Zn‐contaminated (ZnWW), Cu + Zn (CuZnWW) in a completely randomized design. Compared ZnWW, CuWW or CuZnWW had severe mineral absorption by wheat. Irrigation reduced shoot length, root dry weights 44–45%, 54–56%, 5–6%, 33–34%, respectively, against control. Similarly, these diminished chlorophyll a, b, carotenoids, SPAD 59–60%, 49–51%, 26–27%, respectively. Conversely, improved total polyphenols, polyphenolic acids, flavonoids, antiradical activity, however, maximum increase parameters up 65% observed when irrigated ZnWW. Pearson correlation showed that decline growth physiology negatively correlated metal uptake. Dehydrogenase activity is severely hampered lesser extent ZnWW well. These results suggest adversely affects found be less crops than Cu. Thereby, this data highlights need tailored approach prioritize lower toxicity during use practice. Practitioner Points (20 ppm Cu) substantially (80 ppm) compared Wheat increased biologically active compounds shoot. Contaminated affected minerals part soil wastewater. leftover crop residues resulted accumulation organic matter soil.

The present study investigates the impact of varying concentrations PVC microplastics (PVC–MPs) – specifically 0 (no PVC–MPs), 2, and 4 mg L− 1 –alongside different arsenic (As) levels As), 150, 300 kg− in soil, with concurrent application copper oxide–nanoparticles (CuO–NPs) at CuO –NPs), 25 50 µg mL− to barley (Hordeum vulgare L.) plants. This research primarily aims assess plant growth biomass, photosynthetic pigments gas exchange characteristics, oxidative stress indicators, as well response various antioxidants (both enzymatic non-enzymatic) their relevant genes expression, proline metabolism, AsA–GSH cycle, cellular fractionation within findings showed that increased PVC–MPs As soil significantly reduced pigments, characteristics. Additionally, roots shoots, evidenced by elevated malondialdehyde (MDA), hydrogen peroxide (H2O2), electrolyte leakage (EL), which turn stimulated production non-enzymatic antioxidants, gene sugar content. Furthermore, a notable increase pigmentation was observed. Conversely, CuO–NPs resulted substantial improvement activity along reduction stress. enhanced while decreasing metabolism AsA-GSH cycle H. These outcomes provide new insights into sustainable agricultural practices offer significant potential addressing critical challenges heavy metal contamination soils.
