Newton Fund - Development and validation of low-cost field sensor and filtration technologies for real-time detection and removal of drinking water contaminants (As/F-)

千年发展目标7c--将无法持续获得安全饮用水的40亿人减少一半--鼓励了水质检测的快速增长。尽管如此，通过受污染的饮用水暴露于高水平的砷和氟仍然是一个全球健康问题，全球估计有3亿人受到影响，其中墨西哥超过600万人。长期接触砷会导致许多健康问题，包括皮肤病和癌症，而长期接触氟化物会导致骨骼和关节畸形以及牙齿问题。这两种方法都无法治愈；唯一的解决办法是通过负担得起的检测和过滤来防止过度暴露。在这个项目中，两个团队将合作开发基于测试条的新型现场测试，以实现快速、易于使用和负担得起的测试，同时开发一种新型的氟化物过滤器，以配合之前开发的砷过滤器。两个团队将开发一款智能手机应用程序，帮助解决这个问题，并将开发低成本电子阅读器的原型。新的传感器和实验室规模过滤器将在墨西哥受影响最严重的地区之一的现场试验中得到验证。

Millennium Develop Goal 7c - to reduce by half the 4 billion people without sustainable access to safe drinkingwater - has encouraged rapid growth in water quality testing. Despite this, exposure to high levels of arsenic &fluoride through contaminated drinking water remains a global health problem, affecting an estimated 300mpeople worldwide & over 6m people in Mexico. Chronic exposure to arsenic leads to numerous health issues,including skin lesions & cancers, while long-term exposure to fluoride leads to bone and joint deformities anddental problems. No cure exists for either; the only solution is to prevent excessive exposure throughaffordable testing & filtration. In this project the teams will collaborate to develop novel test strip-based fieldtests for both that will be rapid, easy-to-use & affordable, while also developing a novel fluoride filter to goalong with an arsenic filter developed previously. The teams will develop a smartphone app that will help tomap the problem & will develop prototypes of the low-cost electronic readers. The new sensors & lab-scalefilter with be validated in field trials in one of the worst affected regions of Mexico.
