Article Synopsis
- The study assessed the toxicity of nano-sized ZnO (nZnO) and micro-sized ZnO (mZnO) particles on duckweed, revealing that nZnO was more toxic, especially in plant tissue accumulation.
- Both nZnO and mZnO diminished growth rates and disrupted photosynthesis, indicated by changes in chloroplast structure and lower photosystem II efficiency.
- Exposure to both particle sizes led to oxidative stress, DNA damage, and altered antioxidant defenses, with nZnO causing more severe effects due to higher zinc absorption and resulting redox imbalance.
Thallium (Tl) is a highly toxic heavy metal whose mechanism of toxicity is still not completely understood. The aim of this study was to test Tl cytotoxicity on several cell lines of different tissue origin in order to clarify specific Tl toxicity to a particular organ. In addition, possible interference of Tl with cell potassium (K) transport was examined.

In biological systems, AgNPs tend to aggregate and dissolve, so they are often stabilized by agents that affect their physicochemical properties. In this study, microalga was used as a model organism to evaluate the effects of AgNPs in aquatic habitats.

In this study, roots were exposed to 0.01, 0.
View Article and Find Full Text PDFThe harmful effects of silver nanoparticles (AgNPs) have been confirmed in many organisms, but the mechanism of their toxicity is not yet fully understood. In biological systems, AgNPs tend to aggregate and dissolve, so they are often stabilized by coatings that influence their physico-chemical properties. In this study, the effects of AgNPs with different coatings [polyvinylpyrrolidone (PVP) and cetyltrimethylammonium bromide (CTAB)] on oxidative stress appearance and proteome changes in tobacco () seedlings have been examined.
