In the present study, adopting of citizen science approach for monitoring water quality of a lake (Uzungöl, Turkey) was investigated. The study consisted of selection of sampling points and water quality parameters, training of volunteers, sampling and analysis by volunteers, and development of a mobile application for data collection and storage. In the scope of the study, four measurement points around the lake were selected and elementary school students were trained both theoretically and practically to collect water quality data. During the project (June-December, 2018), volunteers collected water samples and measured temperature, pH, nitrate, and phosphate with the given test kits. The mobile application was developed using open source code and used to collect and store the volunteer data. According to the volunteer data, temperature values were between 8.5 and 15.5 °C, pH values were between 2 and 8.5, nitrate values were between 0.5 and 2.5 mg/L, and phosphate values were between 0.5 and 5 mg/L in the lake. Most of the pH and temperature results were compatible with field measurements done by research group during field visits. The motivation of the volunteers and mobile application development were the achievements of the project. Low number of the data and its reliability were the main limitations. Therefore, this study showed that citizen science has both capabilities and constraints for collection of water quality data, however; outstanding potential of citizen science is obvious.
本研究采用公民科学方法监测了土耳其的乌尊哥乐湖（Uzungöl）的水质。研究包括采样点和水质参数的选择、志愿者培训、志愿者采样和分析，以及开发用于数据收集和存储的移动应用程序。在研究范围内，在湖的周围选择了四个测量点，并对小学生进行了理论和实践培训，以收集水质数据。在项目期间（2018 年 6 月至 12 月），志愿者使用给定的测试试剂盒采集水样并测量温度、pH 值、硝酸盐和磷酸盐。该移动应用程序是使用开源代码开发的，用于收集和存储志愿者数据。根据志愿者数据，湖中的温度值在 8.5 到 15.5°C 之间，pH 值在 2 到 8.5 之间，硝酸盐值在 0.5 到 2.5mg/L 之间，磷酸盐值在 0.5 到 5mg/L 之间。大多数 pH 值和温度结果与研究小组在实地考察期间进行的实地测量结果相吻合。志愿者的积极性和移动应用程序的开发是项目的成果。数据数量少及其可靠性是主要限制因素。因此，本研究表明，公民科学在水质数据收集方面具有能力和限制，但公民科学的巨大潜力是显而易见的。
