Heavy metal toxicity induced by sewage water treatment in three different vegetables (lettuce, spinach and cabbage) was alleviated by brassinosteroid and silicon supplementation

Journal of King Saud University - Science, Journal Year: 2024, Volume and Issue: 36(8), P. 103310 - 103310

Published: June 17, 2024

Purpose: Heavy metal stress due to the application of sewage water is considered a leading factor for constrained plant growth. Therefore, Current study was performed in field investigate interactive influence two irrigation sources (canal and sewage) exogenous brassinosteroid (BRs) silicon (Si) at different rates on growth, photosynthetic physiological attributes three leafy vegetables (lettuce, cabbage, spinach). Methods: Three treatments were applied such as control, BRs Si with replications under split plot factorial design. Results: The results indicated that all growth parameters including fresh biomass plants roots, dry root, leaf area (LA), traits, chlorophyll contents, use efficiency (WUE), activity antioxidant enzymes; superoxide dismutase (SOD), peroxidase (POD), Catalase (CAT), ascorbate (APX) uptake except Cd Pb contents improved significantly foliar spray over control treatment both types sources. However maximum improvement recorded when canal irrigation. Conclusions: proved an ameliorating strategy improving tolerance mechanisms associated heavy stress. major restoring mechanism restricted translocation better physiology water. Thus reduced detrimental effect led improve traits

Agricultural Mitigation Strategies to Reduce the Impact of Romaine Lettuce Contamination

Plants, Journal Year: 2024, Volume and Issue: 13(17), P. 2460 - 2460

Published: Sept. 3, 2024

Background: Leafy greens, particularly romaine lettuce, are often associated with outbreaks due to their susceptibility contamination from various environmental sources. This study aimed evaluate the presence of E. coli, Salmonella, copper, nickel, zinc, and manganese in irrigation water, lettuce leaves, agricultural soil Litani River Basin (LRB), Lebanon. Method: Samples were collected five demonstration plots employing different practices. Heavy metal concentrations determined using atomic absorption spectrometry, while coli Salmonella testing conducted through conventional culturing techniques. The impact on seed germination interaction effects between heavy metals also examined. compared effectiveness systems reducing bacterial contamination. Results: results demonstrated that levels varied significantly across types. variation underscores necessity site-specific mitigation strategies enhance food safety. Our findings highlight importance selecting appropriate methods implementing tailored practices minimize risk Conclusion: research provides valuable insights for optimizing LRB ensure safety sustainability.

Investigation of Heavy Metal Contamination in Fruits and Vegetables from Local Markets of Chennai, Tamil Nadu, India

Journal of Advances in Biology & Biotechnology, Journal Year: 2024, Volume and Issue: 27(9), P. 179 - 191

Published: Aug. 22, 2024

Certain areas of Chennai such as red hills, Minjur, T. Nagar, Thiruvanmyur, Ambattur have been found to be particularly susceptible high pollution levels due severe traffic congestions, the ignition coal, cement industries, State Industries Promotion Corporation Tamil Nadu Limited (SIPCOT) and other chemical industries etc., which pose threat environment. The population besides these also increasing employment opportunities activities. Considering persistent nature, cumulative behaviour, probability toxicity heavy metals from it can enter food chain linking plant system soil (fruits & vegetables) transformed human body. metals, Chromium, Cadmium, Nickel Lead, when exceed their permissible limit (≤0.05 ppm), causes metabolic malfunctions beings. At this at background, a study was attempted on metal deposits in fruits vegetables surrounding local markets designated locations. Although there numerous research studies conducted worldwide subject, is first its kind district. Vegetable fruit samples collected near industrial zones congested were analysed compared for against global safety standards ensure that consumed without risk contamination. study's findings demonstrated all had contaminants below detectable thresholds (0.05 ppm) within WHO allowed limits (Cd- 0.2ppm, Pb - 0.3 ppm, Ni 67.9 Cr- 0.00 ppm). This indicates may no possible health concerns linked concentrations highly polluted or with congestion.

Evaluating Parental Knowledge and Behaviors Regarding Developmental Toxicants in Jazan, Saudi Arabia Using the Prevention of Toxic Chemicals in the Environment for Children Tool (PRoTECT)

Healthcare, Journal Year: 2024, Volume and Issue: 12(17), P. 1764 - 1764

Published: Sept. 4, 2024

This study evaluated the level of knowledge among parents in Jazan, Saudi Arabia, regarding substances that can harm child development. The Prevention Toxic Chemicals Environment for Children Tool (PRoTECT) was used this assessment. A cross-sectional survey using a multi-stage cluster random sampling approach undertaken 424 who were enlisted from eight primary healthcare centers (PHCCs). PRoTECT score’s median value 72 out 90, suggesting generally high awareness. found individuals with higher education, particularly those postgraduate degrees, had greater awareness protecting their children’s health. Interestingly, unemployed and residing mountainous areas also demonstrated awareness, possibly due to having more time focus on health well-being. Most participants (68.2%) acknowledged correlation between exposure toxic chemicals during pregnancy early childhood, subsequent development neurodevelopmental disorders. solid foundation knowledge, 85.1% interested learning about reducing exposure, but it stressed need specific actions turn into prevention. These findings would help policymakers develop effective strategies, such as targeted educational campaigns, collaboration providers, utilization media channels, encouragement community-led initiatives, reduce developmental toxicants line national global environmental initiatives. Future research should longitudinal consciousness behavior evaluations regional contaminants.
