“…In order to terminate the growth of the PbO-NPs and stabilize them, the long-chain gelatin compounds were utilized. The calcination of the gel obtained was done at 500, 550, and 600°C for 1 h. Miri et al [45] have synthetized PbO-NPs through the utilization of gelatin as a green stabilizer.…”

“…In the study of Miri et al [45], the electronic spectra of the synthesized PbO-NPs have displayed a wide peak in 250-260 nm at the calcination temperatures of 450, 500, 550, and 600°C. They have discovered that by increasing the temperature from 450 to 600°C, the wavelength is repositioned from 252 to 260 nm, and the alpha form of PbO converts to beta.…”

“…In addition, the TEM results showed that the average particle size of the nanoparticles was ~45 nm. It is possible to note that by changing the method of synthesis, i.e., from chemical to sol-gel method, the nanoparticle size decreases from 60 [23] to 45 nm [44] and even to around 10-20 nm [45].…”

“…Thermal stability and various transitions/ reactions occur in nanostructured PbO and PbS during heat treatment in air and inert atmosphere [42]. In the research carried out by Miri et al [45], the thermal analysis of TGA-DTA of the synthesized sample was performed in the temperature interval of 20-1000°C in an atmospheric air. On the DTA curve, the dehydration and discharge of crystalline and absorbed water were attributed in the temperature Synthesis, Characterization, Applications, and Toxicity of Lead Oxide Nanoparticles DOI: http://dx.doi.org/10.5772/intechopen.91362 range of 80-235°C.…”

“…The major lead pigment is the red lead (Pb 3 O 4 ), which is used principally in ferrous metal protective paints, and litharge, a bright yellow form of lead monoxide, still finds applications in the production of yellow pigments. The colors that contain lead-based pigments seem to have interesting properties including rustproof, antibacterial, and anti-algae, which are extensively employed in shipbuilding, construction skeleton, and road construction [45].…”

Over the past few years, the interest of material scientists for metal and metal oxide nanoparticles (NPs) is increasing dramatically because of their unique physicochemical characteristics such as catalytic activity and optical, electronic, antibacterial, and magnetic properties which depend on their size, shape, and chemical surroundings. Recently, several new routes of synthesis of lead monoxide (PbO) nanoparticles have been used, such as chemical synthesis, calcination, sol-gel pyrolysis, anodic oxidation, solvothermal method, thermal decomposition, chemical deposition, laser ablation, and green methods. Essentially, for the structural characterization of lead oxide nanoparticles, several spectroscopic, microscopic, and thermogravimetric methods of analysis are used. Lead oxide has been widely utilized in batteries, gas sensors, pigments, ceramics, and glass industry. Furthermore, lead oxide nanoparticles are graded as toxic and dangerous for the human health and environment. Therefore, there is an urgent need to develop new approaches and standardized test procedures to study the potential hazardous effect of nanoparticles on the human health and environment. The aim of this chapter is to provide an overview of the recent trends in synthesis of lead oxide nanoparticles, their characterization, possible applications, and toxicity.

Nanoparticles of cerium oxide (CeO2‐NPs), as a metal oxide of rare earth, have found an important role in improving technologies such as polishing, the degradation of harmful industrial dyes and even the treatment of some diseases. Therefore, the development of quick and inexpensive production methods for CeO2‐NPs is sought by researchers. In the present study, we report the biosynthesis of CeO2‐NPs using aqueous extract of Salvadora persica. Synthesized nanoparticles were investigated through powder X‐ray diffraction (PXRD), ultraviolet–visible (UV–vis), Fourier transform infrared, transmission electron microscope (TEM), field emission scanning electron microscopy (FESEM), energy‐dispersive X‐ray and Raman techniques. The UV–vis result shows an absorption peak at 325 nm, which confirms the formation of CeO2‐NPs. The band‐gap of synthesized nanoparticles (4.1 eV) is higher than in its bulk state. PXRD and Raman show a crystalline fluorite cubic structure for synthesized nanoparticles. The morphology of synthesized nanoparticles shows a uniform and almost spherical shape via TEM and FESEM images. The particles size was estimated in the range of 10–15 nm. Cytotoxic activity of synthesized nanoparticles was determined through 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide assay against a colon (HT‐29) cancer cell line. The results did not show any significant cytotoxic effect for synthesized samples even for concentration higher than 800 μg/mL. Hence, CeO2‐NPs were synthesized using a natural source; the procedure was rapid with good productivity and biosynthesized nanoparticles were non‐toxic.

In this work, we developed and used research methods that will make it possible to quickly assess the toxic activity of, among others, metal nanoparticles. In this work, we assessed the toxicity of PbO nanoparticles obtained from biological synthesis using Farfarae folium. The obtained PbO nanoparticles were characterized with the use of such methods as UV-VIS, XRD, SEM with EDS, AFM and FTIR. The techniques applied in the work confirmed the presence of 30-40 nm PbO nanoparticles.The toxic properties of biologically synthesized nanoparticles were assessed with the use of plants and invertebrates. The phytotoxicity studies were conducted on the following plant seeds: radish, garden cress, bean, rape, chia, lupine, corn, and beetroot. The IC50 coefficient was calculated on the basis of the logarithmic relationship A w = a*ln(C) + b. The studies also used the following invertebrates: Daphnia pulex, Tubifex tubifex, Chaoborus sp. (larva), Chironomus aprilinus, Artemia sp. The EC50 coefficient was calculated after the incubation period. For PbO nanoparticles, we managed to identify the IC50 coefficient for selected plants. It was, respectively, 0.150 mg/ml for lupine; 0.274 mg/ml for bean; and 0.655 mg/ml for radish.As regards the studies on invertebrates, it was observed that the most sensitive organisms were Daphnia pulex (EC50 = 0.32 mg/ml) and Tubifex tubifex (EC50 = 0.38 mg/ml), and the most resistant one was Chironomus aprilinus (EC50 = 0.83 mg/ml).
