Carbon Microsphere From Postconsumer Soft Drink Bottles and Their Impact On Plant Growth Study of Cicer Arietinum
AI summary Read the abstract
This study converted waste PET plastic bottles into carbon nanospheres and tested their effects on the germination and growth of chickpea plants (Cicer arietinum). The nanospheres were characterized by electron microscopy and spectroscopy, and plant biochemical responses were analyzed.
Abstract Present work is highlighted on the conversion of waste PET plastics to carbon nanosphere, their characterization by SEM-EDX, XRD and FTIR and finally their application in the field of germination of Cicer arietinum and biochemical analysis. SEM and XRD results revealed that PET plastic are comfortably converted to carbon microsphere with a diameter ranges between 2-8 µm with amorphous nature and FTIR study suggested that the existence of aromatic C-H and aromatic ring along with carbonyl groups. Root morphology suggested that both root length and seminal root number gradually decrease with increasing carbon microsphere dose. Biochemical results revealed that the level of proline, catalase and MDA levels significantly (p < 0.0001) increase with increasing the dose of carbon microsphere. Finally, it can be concluded that lower dose of carbon microsphere could be beneficial for both seed germination and seedling growth, but higher dose may have adverse effect on plant community.

Researchers studied the effects of polyethylene terephthalate (PET) microplastics on chickpea germination and onion root tip cells at concentrations ranging from 50 to 1,000 mg/L. The study found a sharp decrease in germination rates along with biochemical changes and cytotoxic effects at higher microplastic concentrations. Evidence indicates that PET microplastics in soil can negatively affect both plant development and cellular processes.

Stress response to nanoplastics with different charges in Brassica napus L. during seed germination and seedling growth stages
AI summary Read the abstract
Exposure to polystyrene nanoplastics at 200 mg/L significantly reduced seed germination, root elongation, biomass, photosynthesis, and essential nutrient uptake in rapeseed, with positively charged PS-NH2 particles producing the strongest toxic effects across all measured parameters. These findings demonstrate that nanoplastic surface charge is a key determinant of phytotoxicity, raising concerns about crop yield and food quality in farmlands contaminated by nanoplastic runoff.
