We synthesized the effects of ozone on wheat quality based on 42 experiments performed in Asia, Europe and North America. Data were analysed using meta-analysis and by deriving response functions between observed effects and daytime ozone concentration. There was a strong negative effect on 1000-grain weight and weaker but significant negative effects on starch concentration and volume weight. For protein and several nutritionally important minerals (K, Mg, Ca, P, Zn, Mn, Cu) concentration was significantly increased, but yields were significantly decreased by ozone. For other minerals (Fe, S, Na) effects were not significant or results inconclusive. The concentration and yield of potentially toxic Cd were negatively affected by ozone. Some baking properties (Zeleny value, Hagberg falling number) were positively influenced by ozone. Effects were similar in different exposure systems and for spring and winter wheat. Ozone effects on quality should be considered in future assessments of food security/safety.
基于在亚洲、欧洲和北美洲进行的42项实验，我们综合分析了臭氧对小麦品质的影响。使用元分析方法并通过推导观测效应与日间臭氧浓度之间的响应函数对数据进行了分析。臭氧对千粒重有强烈的负面影响，对淀粉浓度和容重有较弱但显著的负面影响。对于蛋白质以及几种营养上重要的矿物质（钾、镁、钙、磷、锌、锰、铜），其浓度显著增加，但臭氧使产量显著降低。对于其他矿物质（铁、硫、钠），影响不显著或结果尚无定论。潜在有毒的镉的浓度和产量受到臭氧的负面影响。一些烘焙特性（泽伦尼值、哈格伯格降落数值）受到臭氧的积极影响。在不同的暴露系统以及春小麦和冬小麦中，影响相似。在未来的粮食安全/食品安全评估中应考虑臭氧对品质的影响。
