Urban horticulture and community gardening have become more and more popular in the past years, however, the risk of bioaccumulation of atmospheric polyaromatic hydrocarbons (PAHs) in vegetables grown in polluted areas cannot be neglected. In our study, the No. 227 OECD GUIDELINE FOR THE TESTING OF CHEMICALS: Terrestrial Plant Test: Vegetative Vigour Test was followed to assess foliar uptake of PAHs from aqueous extract of an urban aerosol. Using lettuce (Lactuca sativa) as a test organism, significant accumulation was experienced. The highest bioconcentration factors (BCFs) were experienced for naphthalene and for anthracene, pyrene and fluoranthene showed the lowest bioaccumulation potential. BCF of each PAH showed strong correlation with molecular weight. The standard protocol defined by the Guideline made it possible to assess bioaccumulation pattern under controlled laboratory conditions.
在过去的几年中，城市园艺和社区园艺越来越受欢迎，然而，在污染地区种植的蔬菜中大气多环芳烃（PAHs）生物累积的风险不容忽视。在我们的研究中，遵循了第 227 号经合组织化学品测试指南：陆生植物测试：营养体活力测试，以评估从城市气溶胶的水提物中叶片对 PAHs 的吸收。使用生菜（Lactuca sativa）作为测试生物，经历了显著的积累。萘和蒽的生物浓缩系数（BCF）最高，而苊、芘和荧蒽的生物累积潜力最低。每种 PAH 的 BCF 与分子量呈强相关性。该指南规定的标准方案使得在受控实验室条件下评估生物累积模式成为可能。
