人类医疗和动物养殖均大量使用抗生素,通常大部分以药物原形随粪尿排出,造成环境污染[1-4]。珠三角地区、天津市等地蔬菜基地土壤、蔬菜中普遍检出抗生素[5-8],危害农产品安全和人体健康。筛选污染物低累积蔬菜品种是保障蔬菜质量安全的重要策略。对于重金属、邻苯二甲酸酯等污染物低累积蔬菜品种筛选已有一些报道[9-11],但对于抗生素低累积蔬菜品种筛选尚未见报道。为此,本研究探讨了广州地区7种主要基因型空心菜-水培系统(设置污染水平Ⅰ、Ⅱ、Ⅲ分别为0.05、0.25、1mg·L-1)中环丙沙星和恩诺沙星的吸收累积与残留特征,以期为农产品安全提供科学参考。
Large amounts of antibiotics are used in human medical and animal breeding, and most of them are excreted in the form of drugs with the excrement and cause environmental pollution [1-4]. In the Pearl River Delta, Tianjin and other places vegetable base soil, vegetables are generally detected in antibiotics [5-8], endangering the safety of agricultural products and human health. Screening for contaminants Low accumulation of vegetable varieties is an important strategy to ensure the quality and safety of vegetables. There have been some reports on the screening of vegetables with low accumulation of heavy metals, phthalates and other pollutants [9-11], but there is no report on screening of low cumulative vegetable varieties of antibiotics. In this study, we investigated the effects of ciprofloxacin and enrofloxacin on seven major genotypes of Chinese cabbage-hydroponic system (setting pollution levels Ⅰ, Ⅱ and Ⅲ as 0.05, 0.25 and 1 mg · L -1, respectively) Absorption of the cumulative and residual characteristics, with a view to provide a scientific reference for the safety of agricultural products.
