The articles reviewed in this collection focus on the effects of lead (Pb) on plants, including its toxicity, uptake, and detoxification. The studies discuss the impacts of Pb on plant growth, photosynthesis, and antioxidant enzymes, as well as the role of silicon (Si) in mitigating Pb toxicity. The articles also investigate the use of nano-silica and other nanoparticles to improve crop yield and reduce metal toxicity. Additionally, the collection includes research on the effects of Pb on human health and the environment, as well as the use of microorganisms to remediate contaminated soil.
Some of the key findings include:
* Pb can have detrimental effects on plant growth and development, including reduction of chlorophyll production and disruption of photosynthesis.
* Silicon can help to reduce Pb uptake and toxicity in plants by forming a physical barrier around the plant’s roots and improving antioxidant defenses.
* Nano-silica and other nanoparticles can be used to improve crop yield and reduce metal toxicity by increasing water absorption, reducing oxidative stress, and promoting nutrient uptake.
* Lead toxicity can also have negative effects on human health, including neurological and reproductive problems.
* Microorganisms can be used to remediate contaminated soil by breaking down heavy metals and improving soil structure.
Overall, the collection highlights the importance of understanding the effects of Pb on plants and the environment, as well as the potential benefits of using silicon and other materials to mitigate its toxicity.
