一种新型的腕带可以帮助科学家发现当前尚未被证明但经常食用的化合物存在的健康隐患。
从“活得健康”到“紫色蹄爪”，这些时尚的腕带开始相应地代表癌症和停止虐待动物。添加一种新型的腕带：一种能判断暴露在不同环境下潜在的患病风险的腕带，如有农药的环境。科学家将这一发现发表在美国癌症协会的《环境科学与技术》期刊上。金·安德森和他的同事在发表的论文中指出，人们每天呼吸、接触并消化多种不同的低级别的物质。但确定自然或合成的化合物是否会引发疾病尚难以判断。数以千计的化合物出现在常见的消费产品和工业过程中，但并不是所有的这些化合物都被监测是否有毒。研究提示，部分物质与人体健康问题存在联系，然而，找到明确的因果关系需要长期的测验。
目前，人们监测接触物品使用的是沉重的背包采样器、问卷或者固定设备，这些都存在不足。安德森的研究团队找到了更好更精确地评估一个人暴露在潜在有毒环境的方法。
A new kind of wristband could help scientists figure out the health risks of currently untested but commonly used compounds.
From "Livestrong" to "Purple Paws," trendy wristbands have come to represent causes from cancer to ending cruelty to animals. Add a new wristband of a different sort: one that could close the loop on determining the potential disease risks of exposure to substances like pesticides. Scientists reported the development in the ACS journal Environmental Science & Technology. Kim Anderson and colleagues note that people breathe, touch and ingest a mix of many substances at low levels every day. But figuring out if natural and synthetic compounds can lead to disease is difficult. Thousands of these compounds are in common consumer products and industrial processes, but not all of them have been tested for toxicity. Research suggests that there's a link between some of these substances and human health problems. However, establishing cause and effect definitively requires long-term measurements.
Currently, people monitor exposure with heavy backpack samplers, questionnaires or with stationary devices, which all have disadvantages. Anderson's team looked for a better way to more accurately assess an individual person's exposure to possible toxins.
