Arsenic (As) testing could help 22 million people, using drinking water sources that exceed the Bangladesh As standard, to identify safe sources. A cluster randomized controlled trial was conducted to evaluate the effectiveness of household education and local media in the increasing demand for fee-based As testing. Randomly selected households (N = 452) were divided into three interventions implemented by community workers: 1) fee-based As testing with household education (HE); 2) fee-based As testing with household education and a local media campaign (HELM); and 3) fee-based As testing alone (Control). The fee for the As test was US$ 0.28, higher than the cost of the test (US$ 0.16). Of households with untested wells, 93% in both intervention groups HE and HELM purchased an As test, whereas only 53% in the control group. In conclusion, fee-based As testing with household education is effective in the increasing demand for As testing in rural Bangladesh.
砷（As）检测可以帮助 2200 万人，通过使用超过孟加拉国砷标准的饮用水源，来识别安全水源。本研究采用整群随机对照试验，评估了家庭教育和当地媒体在增加收费砷检测需求方面的有效性。随机选择的家庭（N=452）分为由社区工作者实施的三种干预措施：1）收费砷检测与家庭教育（HE）；2）收费砷检测与家庭教育和当地媒体运动（HELM）；3）单独收费砷检测（对照）。砷检测费用为 0.28 美元，高于检测成本（0.16 美元）。在未检测水井的家庭中，干预组 HE 和 HELM 的 93%都购买了砷检测，而对照组只有 53%。总之，收费砷检测与家庭教育相结合在增加孟加拉国农村地区砷检测需求方面是有效的。
