Abstract

In rural areas with high fluoride concentrations in groundwater, affordable and effective de-fluoridation technologies can significantly reduce the likelihood of being affected by fluorosis-related illnesses, such as skeletal fluorosis. This is particularly significant in areas where groundwater is the primary or sole drinking water source, such as the Rift Valley of Tanzania. Despite the availability of technologies, people's use of de-fluoridation devices still needs to be improved. This study investigates the potential impact of fear appeals on promoting protective behaviors and willingness to pay for fluoride-free water. The fear appeal emphasizes the negative health effects of drinking water with high fluoride levels and suggests using water from a specific de-fluoridation device to reduce the risk of being affected by skeletal fluorosis. To analyze the impact of the fear appeal, we use the Extended Parallel Process Model within a contingent valuation survey conducted in the Rift Valley of Tanzania. Results show that the theoretical components of this model have varying roles in the presence and absence of health risk perceptions. Respondents who receive health risk information are more willing to pay for fluoride-free water than other participants and are interested in adopting precautionary behavior. Governmental institutions and donors should collaborate to improve education on the health risks of drinking water with high fluoride concentrations. Additionally, they should work on enhancing de-fluoridation technology and developing effective risk communication strategies, specifically focusing on individuals' cognitive-behavioral outcomes.

氟污染地区的恐惧诉求、个人的认知行为反应以及为安全饮用水付费的意愿。
在地下水含氟量较高的农村地区,经济有效的除氟技术可以大大降低患氟中毒相关疾病(如骨骼氟中毒)的可能性。这对于以地下水为主要或唯一饮用水源的地区尤为重要,如坦桑尼亚的大裂谷地区。尽管已有相关技术,但人们对除氟装置的使用仍有待提高。本研究调查了恐惧呼吁对促进保护行为和无氟水付费意愿的潜在影响。恐惧诉求强调了饮用高氟含量水对健康的负面影响,并建议使用特定除氟装置中的水以降低受骨骼氟中毒影响的风险。为了分析恐惧呼吁的影响,我们在坦桑尼亚裂谷进行的或然估值调查中使用了扩展平行过程模型。结果表明,该模型的理论成分在存在和不存在健康风险认知时的作用各不相同。与其他参与者相比,接受健康风险信息的受访者更愿意为无氟水付费,并有兴趣采取预防行为。政府机构和捐助方应通力合作,加强有关饮用高浓度氟水的健康风险的教育。此外,他们还应该努力提高除氟技术,并制定有效的风险沟通策略,尤其要关注个人的认知行为结果。

期刊介绍: The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
