Tea is consumed widely around the world owing to its refreshing taste and potential health benefits. However, drinking tea is considered a major route for dietary aluminum exposure in areas where tea consumption is relatively large. To assess the health risk associated with drinking tea, the contamination level of aluminum was determined in 81 tea samples. The transfer rate of aluminum during tea brewing was investigated. Then based on the site-specific exposure parameters such as consumption data and body weight for six different subpopulations in Fujian, the exposure risks were estimated using a probabilistic approach. Results demonstrate that the contents of aluminum in green tea, white tea, oolong tea, and black tea were significantly different according to the one-way ANOVA analysis ( < 0.05). The transfer rate of aluminum were 32.6%, 31.6%, 26.3%, and 14% for white tea, black tea, oolong tea, and green tea, respectively. With respect to the oral reference dose, the exposure of inhabitants in Fujian to aluminum through drinking tea is under control (even at the 99th percentile).
由于茶具有清新的口感和潜在的健康益处，因此在世界各地广受欢迎。然而，在茶叶消费相对较大的地区，喝茶被认为是膳食铝暴露的主要途径。为了评估与饮茶相关的健康风险，测定了 81 个茶叶样品中的铝污染水平。研究了茶叶冲泡过程中铝的转移率。然后，根据福建六个不同亚人群的特定暴露参数，如消费数据和体重，使用概率方法估计暴露风险。结果表明，根据单因素方差分析（ < 0.05），绿茶、白茶、乌龙茶和红茶中的铝含量有显著差异。铝的转移率分别为白茶、红茶、乌龙茶和绿茶的 32.6%、31.6%、26.3%和 14%。就口服参考剂量而言，福建居民通过饮茶摄入铝的暴露量处于控制之下（即使在第 99 百分位）。
