The large-scale use of pesticides is one of the main causes of the dramatic degradation of our environment. Pesticides such as imidacloprid (IMID) have been linked to declines in bee health and toxicity to other beneficial insects. They pose a threat to human health due to their persistence in the environment and accumulation in the food chain. Therefore, it is essential to test possible environmentally-friendly solutions for their elimination. The present study evaluates the efficiency of microalgae Nannochloropsis sp. for the removal of IMID from synthetic wastewater. The influence of aeration, light, and the presence of UV radiation on the degradation of IMID were factors considered in the study. A rapid RP-HPLC method was developed and validated for the analysis and quantification of IMID in the context of bioremediation with microalgae. Nannochloropsis sp. removed 4.39 µg mL⁻¹ from an initial content of 9.59 µg mL⁻¹ (reaching approximately 50%) of IMID in the first 20 h. This study demonstrated that the removal of IMID by the marine microalgae Nannochloropsis sp. is both effective and light-dependent.

大规模使用杀虫剂是我们环境急剧恶化的主要原因之一。吡虫啉 (IMID) 等农药与蜜蜂健康下降和对其他有益昆虫的毒性有关。由于它们在环境中的持久性和在食物链中的积累，它们对人类健康构成威胁。因此，必须测试可能的环保解决方案以消除它们。本研究评估了微藻Nannochloropsis的效率sp. 用于去除合成废水中的 IMID。曝气、光照和紫外线辐射对 IMID 降解的影响是研究中考虑的因素。开发并验证了一种快速 RP-HPLC 方法，用于在微藻生物修复环境中对 IMID 进行分析和定量。微绿球藻属  在前 20 小时内，从 9.59 µg mL ^-1（达到约 50%）的 IMID初始含量中去除了 4.39 µg mL ^-1。该研究表明，海洋微藻Nannochloropsis sp.对 IMID 的去除。既有效又依赖光。
