(1) Background: The widespread use of nanoparticles (NPs) implies their inevitable contact with living organisms, including aquatic microorganisms, making it essential to understand the effects and consequences of this interaction. Understanding the adaptive responses and biochemical changes in microalgae and cyanobacteria under NP-induced stress is essential for developing biotechnological strategies that optimize biomolecule production while minimizing potential toxicity. This study aimed to evaluate the interactions between various potentially toxic nanoparticles and the cyanobacterial strain , focusing on the biological adaptations and biochemical mechanisms that enable the organism to withstand xenobiotic exposure.

However, the effects of untreated wastewater containing high concentrations of chromium and zinc on vegetables and the potential human health risks associated with their consumption are poorly understood. This pot experiment aimed to address this research gap.

- Nanotechnologies, particularly silver and copper nanoparticles, can affect living systems, prompting researchers to study their impact on the plant species L. under field conditions.
- The study measured how these nanoparticles are taken up by different parts of the plant using advanced techniques to analyze accumulation levels.
- Findings showed copper particles concentrated in roots and leaves, while silver particles primarily affected roots and berries, but overall indicated a low human health risk from consuming the nanoparticle-contaminated berries.

Article Synopsis
- * The results showed that these functionalized AgNPs tended to accumulate in the brain, liver, and testicles and cleared from the body after some time, with some mild immune responses and temporary liver stress noted.
- * Overall, the findings suggest that using Spirulina to coat silver nanoparticles improves their safety and effectiveness in medical applications, reducing toxicity while still allowing for therapeutic use.
Nanoparticles, due to their extensive production and application, can have significant consequences for the environment, including soil and plant pollution. Therefore, it is very important to assess how nanoparticles will affect plants depending on the exposure pathways. The effect of gold nanoparticles in a concentration range of 1-100 mg/L on L.
