Leafy greens, particularly romaine lettuce, are often associated with outbreaks due to their susceptibility to contamination from various environmental sources. This study aimed to evaluate the presence of , , copper, nickel, zinc, and manganese in irrigation water, lettuce leaves, and agricultural soil in the Litani River Basin (LRB), Lebanon.
Samples were collected from five demonstration plots employing different agricultural practices. Heavy metal concentrations were determined using atomic absorption spectrometry, while and testing were conducted through conventional culturing techniques. The impact of contamination on seed germination and the interaction effects between and heavy metals were also examined. The study also compared the effectiveness of various irrigation systems in reducing bacterial contamination.
The results demonstrated that contamination levels varied significantly across the plots and irrigation types. This variation underscores the necessity of site-specific mitigation strategies to enhance food safety. Our findings highlight the importance of selecting appropriate irrigation methods and implementing tailored agricultural practices to minimize the risk of contamination.
This research provides valuable insights for optimizing agricultural practices in the LRB to ensure food safety and environmental sustainability.
绿叶蔬菜，尤其是长叶生菜，由于易受各种环境源污染，常与疫情爆发有关。本研究旨在评估黎巴嫩利塔尼河流域（LRB）灌溉水、生菜叶和农业土壤中铅、镉、铜、镍、锌和锰的存在情况。
从采用不同农业实践的五个示范地块采集样本。使用原子吸收光谱法测定重金属浓度，同时通过传统培养技术进行铅和镉检测。还研究了镉污染对种子萌发的影响以及镉与重金属之间的相互作用效应。该研究还比较了各种灌溉系统在减少细菌污染方面的有效性。
结果表明，不同地块和灌溉类型的污染水平差异显著。这种差异强调了制定因地制宜的缓解策略以加强食品安全的必要性。我们的研究结果突出了选择合适灌溉方法和实施定制农业实践以尽量减少污染风险的重要性。
本研究为优化LRB地区的农业实践以确保食品安全和环境可持续性提供了有价值的见解。
