Barriers to communicating the uncertainty of environmental health risks include preferences for certain information and low numeracy. Map features designed to communicate the magnitude and uncertainty of estimated cancer risk from air pollution were tested among 826 participants to assess how map features influenced judgments of adequacy and the intended communication goals. An uncertain versus certain visual feature was judged as less adequate but met both communication goals and addressed numeracy barriers. Expressing relative risk using words communicated uncertainty and addressed numeracy barriers but was judged as highly inadequate. Risk communication and visual cognition concepts were applied to explain findings.
传达环境健康风险不确定性的障碍包括对特定信息的偏好和低数字素养。为传达空气污染导致的估计癌症风险的大小和不确定性而设计的地图特征，在826名参与者中进行了测试，以评估地图特征如何影响对充分性的判断以及预期的沟通目标。一个不确定与确定的视觉特征被认为不太充分，但满足了两个沟通目标并解决了数字素养障碍。用文字表达相对风险传达了不确定性并解决了数字素养障碍，但被认为非常不充分。应用风险沟通和视觉认知概念来解释研究结果。
