1631968ChenThe Flint (Michigan) drinking water contamination crisis brought national attention to lead contamination in drinking water systems. Between 6,000 and 12,000 residents (including children) had severely high levels of lead in the blood and experienced a range of serious health problems. Therefore, rapid and accurate water quality test for various contaminants such as lead (Pb) ions at the point of use is a core requirement for drinking water safety. This project aims to: (1) validate a prototype handheld device for lead ion detection using Flint water samples and improve the handheld device performance, and, (2) enable rapid screening of Flint water for lead ions during the pipeline retrofitting, during seasonal transition from winter to summer, and after, at various point-of-use systems. This RAPID project will contribute to the development of a rapid and low-cost detection method for lead ions in Flint water using a handheld device. Similar to the glucose meter for home use, the handheld device consists of a meter and a disposable (one-time use only) sensor test strip based on reduced graphene oxide. The device is capable of detection of lead ions in water at a concentration well below the maximum contaminant level defined by the US EPA. In this project, the prototype handheld device will be validated for rapid lead ion detection in Flint water samples, which is representative of lead-contaminated drinking water. The resulting handheld device will then be used to enable rapid screening of Flint water for lead ions during the pipeline retrofitting, during seasonal transition from winter to summer, and after new point-of-use systems being developed. The anticipated result of the proposed project is a reliable and rapid point-of-use handheld device for lead screening in drinking water.

1631968年，密歇根州弗林特市的饮用水污染危机引起了全国对饮用水系统中铅污染的关注。6，000至12，000名居民（包括儿童）的血液中铅含量严重偏高，并出现了一系列严重的健康问题。因此，在使用点对各种污染物如铅（Pb）离子进行快速准确的水质检测是饮用水安全的核心要求。该项目旨在：（1）使用弗林特水样本验证用于铅离子检测的原型手持设备，并改进手持设备性能，以及（2）在管道改造期间、从冬季到夏季的季节过渡期间以及之后，在各种使用点系统处，能够快速筛查弗林特水的铅离子。这个快速项目将有助于开发一种使用手持设备快速、低成本检测弗林特水中铅离子的方法。与家用血糖仪类似，手持设备由血糖仪和基于还原氧化石墨烯的一次性（仅一次性使用）传感器测试条组成。该设备能够检测水中的铅离子，其浓度远低于美国环保署规定的最大污染物水平。在该项目中，原型手持设备将被验证用于快速检测弗林特水样中的铅离子，弗林特水样是铅污染饮用水的代表。由此产生的手持设备将用于在管道改造期间，在从冬季到夏季的季节过渡期间以及在开发新的使用点系统之后快速筛选弗林特水的铅离子。拟议项目的预期成果是提供一种可靠、快速的使用点手持设备，用于饮用水中的铅筛查。
