OBJECTIVE
There is growing epidemiological evidence linking nitrate contamination to adverse health outcomes. Health concerns may drive consumers towards bottled water, however, nitrate levels in bottled water are not readily available.
METHODS
We tested water samples from the 10 most popular brands using a TriOS OPUS UV optical nitrate sensor.
RESULTS
Overall, all bottled water brands tested returned nitrate levels below 4.4 mg/L NO3.
CONCLUSIONS
The growing health concerns associated with nitrate contamination suggest that increased reporting of water quality is required.
IMPLICATIONS FOR PUBLIC HEALTH
Mandatory reporting of water quality laboratory reports by bottled water producers would improve transparency to consumers and help public health researchers track potential threats to water quality as new evidence emerges.
目的
越来越多的流行病学证据将硝酸盐污染与不良健康结果联系起来。健康问题可能促使消费者转向瓶装水，但瓶装水中的硝酸盐含量却不易获得。
方法
我们使用 TriOS OPUS UV 光学硝酸盐传感器对 10 个最受欢迎品牌的水样进行了测试。
结果
总体而言，所有测试的瓶装水品牌的硝酸盐含量均低于 4.4mg/LNO3。
结论
与硝酸盐污染相关的健康问题日益严重，这表明需要增加水质报告。
公共卫生意义
瓶装水生产商强制报告水质实验室报告将提高消费者的透明度，并帮助公共卫生研究人员在新证据出现时跟踪水质的潜在威胁。
