Ameliorating arsenic and PVC microplastic stress in barley (Hordeum vulgare L.) using copper oxide nanoparticles: an environmental bioremediation approach.

ABSTRACT: The present study investigates the impact of varying concentrations of PVC microplastics (PVC-MPs) - specifically 0 (no PVC-MPs), 2, and 4 mg L^- 1 -alongside different arsenic (As) levels of 0 (no As), 150, and 300 mg kg^- 1 in the soil, with the concurrent application of copper oxide-nanoparticles (CuO-NPs) at 0 (no CuO -NPs), 25 and 50 µg mL^- 1 to barley (Hordeum vulgare L.) plants. This research primarily aims to assess plant growth and biomass, photosynthetic pigments and gas exchange characteristics, oxidative stress indicators, as well as the response of various antioxidants (both enzymatic and non-enzymatic) and their relevant genes expression, proline metabolism, the AsA-GSH cycle, and cellular fractionation within the plants. The findings showed tha
