Research ArticleOpen accessPhrase in the titlePotentiometric Biosensor for Highly Toxic Pb (lead) and Cd (cadmium) Detection in Milk Using Layer-by-Layer ImmobilizationZhainagul Kakimova, Klara Zharykbasova, Aitbek Kakimov et al.Milk contamination with heavy metals such as lead (Pb) and Cadmium (Cd) poses a serious threat to public health, particularly in industrial regions. To address the need for rapid and on-site detection of these contaminants, a potentiometric biosensor was developed for the quantification of Pb²⁺ and Cd²⁺ ions in milk and dairy products. The biosensor functions by measuring the change … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 8 Feb 2026 · 1,480 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparative SCAPS-1D Study of Lead-Free CsSnCl₃-Based Perovskite SCs Employing Different ETLsRony Tota, Shak Mahmudul Hasan, Md. Morsalin et al.Cesium tin chloride (CsSnCl3) has drawn considerable interest as a non-toxic absorber candidate for next-generation photovoltaic devices, offering an attractive combination of affordability, thermal robustness, and competitive conversion performance suitable for clean-energy deployment. In the present work, the photovoltaic behaviour of CsSnCl₃-based SCs was numerically examined using the SCAPS-1D software. Three distinct device stacks were constructed by varying the ETL, … …American Journal of Engineering and Applied Sciences, Vol. 19, Issue 1 · 22 May 2026 · 1,737 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Lead on the Chlorophyll and Antioxidant Response in the Leaves of Arabidopsis thalianaJun Xing, Cailing Yuan, Hui Yu et al.Lead (Pb) is a non-essential heavy metal element for plants. In this study, the effect of 0.025, 0.05, 0.1, 0.25, and 0.5 g/L Pb on the chlorophyll and antioxidant response was analyzed in the leaves of Arabidopsis thaliana. The results indicate that 0.025 g/L Pb had no significant effect on the fluorescence intensity of chlorophyll. However, 0.05, 0.1, 0.25, and … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 31 Mar 2024 · 4,628 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVisual-Spatial Attention Abilities Among School Children Exposed to Low Environmental Lead LevelSana Maidoumi, Mariam Ouisselsat, Charif Radouan Ouaziz et al.Lead (Pb) is an intrusive toxic matter which harms the neuro-cognitive and behavioral development of children even with doses considered normal. The present paper aims at evaluating the visual-spatial attention function among 142 schoolchildren living in a mining area (cases) in comparison to 177 living in the Chouiter area (control group) in Marrakech. We used the Bell Dam Test (BDT) … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 12 Oct 2022 · 5,406 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWhite Light Generation in Dy3+-Doped Sodium Lead Alumino Borosilicate Glasses for W-LED ApplicationsK. Vijaya Babu, A. Subba Rao, V. Madhuri, K. SureshExcitation and emission spectra of sodium lead alumino borosilicate glass doped with different concentrations of Dy3+ have been reported. The concentration of Dy3+ were varied from 0.5 to 1.5 mol%. As a result of 385 nm excitation wavelength, the luminescence spectra showed three characteristic bands at 482 nm and 575 nm and 665 nm. These absorption bands were attributed to … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 3 Jun 2020 · 6,857 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOxidative Stress and Reproductive Damage Induced by Lead Acetate in Female Guinea Pig (Cavia porcellus): Curative Effects of Hydroethanolic Extract of Spirulina platensisDeutcheu Nienga Sorelle, Ngoula Ferdinand, Manfo Tsague Faustin Pascal et al.This study was aimed at evaluating the curative effects of Hydroethanolic Extract Of Spirulina platensis (HESP) on the reproductive function of female Guinea pig exposed to oxidative stress. Sixty females, 3-4 months old, weighing 300-400 g were divided into six groups (10 animals/group). The neutral control received distilled water, the negative control was treated with lead acetate at a dose … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 1 · 8 Apr 2019 · 7,422 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLead Phytotoxicity Induced Changes in Biochemical Markers in Germination and Seedlings in Durum Wheat Triticum durum Desf. Cv.Vitron and GtaSoraya Slimani, Mokhtar Boudelaa, Saddek Abdelmadjid et al.Among the heavy metals most commonly found on land, lead is a strongly represented pollutant in soil and sediments. It is easily absorbed and accumulated in different parts of plants. On the macroscopic scale, lead causes unfavorable effects on plants. First and in the event of excess, it may exert toxicity affecting several stages of germination development in leaf formation … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 6 Sep 2017 · 7,480 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Impact of Chernozem Contamination with Lead and Oil on the Abundance and Composition of MicroarthropodsSergey Ilyich Kolesnikov, Lidiya Sergeevna Samokhvalova, Maria Gennadievna Zharkova et al.Micro arthropods population reduced with increase in the amount of oil in chernozem. The same pattern was observed up to a certain concentration of lead in the soil (background + 250 mg kg-1) and then at high doses (+500 and +1000 mg kg-1) an increase in microarthropods abundance was recorded. Gamazid mites and acaroid-trombidi form complex mites proved to be … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 29 Apr 2015 · 7,598 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLead in Meat and Meat Products Consumed by the Population in SlovakiaLukáčová Anetta, Golian JozefThe presence of heavy metals in food is the consequence of atmosphere contamination of polluted soil, waters and results in contaminated feed with heavy metals. The lead concentrations depend on the environmental conditions and the food production methods. The monitoring of lead concentration in meat is important for human health.
