This article illustrates how a health impact assessment (HIA) can be used to promote a collaborative discussion among stakeholders as part of a local action plan aimed at improving air quality. We performed a HIA of the mortality impacts of long-term exposure to fine particles PM_2.5 in the Arve Valley in France. This narrow valley can experience high levels of pollution mostly during winter. However, local stakeholders expressed strong, contradictory opinions on the associated health impacts. Our HIA helped overcome existing silos and shifted the overriding question from “Is it true that air pollution kills people?” to “What can we do to improve air quality?” HIAs have proven to be an excellent decision-support tool in many contexts. In addition, they should continue to be useful provided that their scope, specific objectives, choices, calculation assumptions, and limitations are thoroughly explained to all stakeholders and made easily accessible.

对当地利益相关者进行有意义的健康影响评估的条件：以法国Arve谷为例

本文说明了如何使用健康影响评估（HIA）促进利益相关者之间的合作讨论，作为旨在改善空气质量的地方行动计划的一部分。我们进行了长期暴露于PM _2.5微粒对死亡率影响的HIA在法国的Arve山谷中。这个狭窄的山谷主要在冬季会遭受高水平的污染。但是，当地利益相关者对相关的健康影响表达了强烈而矛盾的观点。我们的HIA帮助克服了现有的孤岛，并将最重要的问题从“空气污染确实杀死人吗？”转变了 改为“我们如何才能改善空气质量？” 在许多情况下，HIA已被证明是出色的决策支持工具。此外，只要对所有利益相关者都充分解释了它们的范围，特定目标，选择，计算假设和限制，并使它们易于使用，它们应该继续是有用的。
