A 7-year temporal trend study of artificial sweetener consumption was performed by determining per capital mass loads in 293 influent wastewater samples collected from a wastewater treatment plant in Australia between 2012 and 2018. Population-weighted per capita mass loads of the four detected artificial sweeteners ranged from 2.4 ± 0.8 mg d-1 p-1 for saccharin to 7.8 ± 2.0 mg d-1 p-1 for acesulfame over the study period. Negligible intra-week fluctuations were observed, however the consumption of acesulfame was seen to be significantly influenced by season with the highest consumption in summer. The consumption of sucralose and saccharin significantly increased with an annual increase rate of 10% and 6.0%. Cyclamate consumption declined over the same period with average annual decrease rate of 11%, which agrees with data from market surveys. Sucrose equivalence of total artificial sweeteners consumption showed an increase between 2012 and 2016, then decreased in 2018. This is the first long-term trend study of artificial sweetener consumption by wastewater analysis and highlights the feasibility to quantitatively measure artificial sweeter consumption over time.

人造甜味剂消费趋势:澳大利亚昆士兰州一项基于废水的7年流行病学研究

通过确定2012年至2018年之间从澳大利亚废水处理厂收集的293个进水废水样品中的人均质量负荷,进行了7年人工甜味剂消耗量的时间趋势研究。四种检测到的人工甜味剂的人口加权人均质量负荷糖精的范围从2.4±0.8 mg d -1 p -1到7.8±2.0 mg d -1 p -1在研究期间服用乙磺胺。观察到的周内波动可忽略不计,但是醋磺胺的消费量受季节的影响最大,夏季消费量最高。三氯蔗糖和糖精的消耗量显着增加,年增长率分别为10%和6.0%。同期,甜蜜素的消费量下降了,年均下降率为11%,与市场调查的数据一致。人造甜味剂总消耗量中的蔗糖当量在2012年至2016年间呈上升趋势,然后在2018年下降。这是第一个通过废水分析得出的人造甜味剂消耗量的长期趋势研究,凸显了随时间定量测量人造甜味剂消耗量的可行性。
