摘要

木质颗粒燃料作为一种可再生、可持续的能源越来越受到推崇,预计到 2026 年,全球木质颗粒燃料市场价值将达到 160 亿美元。然而,该行业的快速扩张对南方农村地区的黑人和低收入社区造成了极大的影响,目前美国约有 100 家木质颗粒生产厂。2023 年 8 月至 2024 年 3 月,我们在密西西比州格罗斯特(一个受颗粒生产影响的社区)进行了噪声暴露评估,并将其与附近没有工业活动的社区门登霍尔进行了比较。我们与当地一家机构合作,对噪声指标进行了测量,发现格罗斯特的 A 加权、C 加权和 Z 加权声级明显较高,多个中心频率的分贝也有所升高。这些发现表明,木质颗粒制造会严重改变农村社区的声景,引发环境正义问题。我们的发现强调了调查噪声和其他环境负担对这些脆弱社区的累积健康影响的重要性,以便更好地为政策提供信息。

Amplifying concerns: An exploration of community noise levels in rural communities impacted by wood pellet production
Wood pellets are increasingly promoted as a renewable and sustainable energy source, driving the global wood pellet market to a projected value of $16 billion by 2026. However, the rapid expansion of this industry disproportionately affects predominantly Black and low-income communities in the rural South, where approximately 100 pellet manufacturing plants are currently located in the United States. From August 2023 to March 2024, we conducted a noise exposure assessment in Gloster, Mississippi, a community affected by pellet production, and compared it to Mendenhall, a nearby community without industrial activity. In collaboration with a local organization, we measured noise metrics and found significantly higher A-weighted, C-weighted, and Z-weighted sound levels in Gloster, along with elevated decibels at multiple center frequencies. These findings suggest that wood pellet manufacturing can severely alter the soundscape of rural communities, raising environmental justice concerns. Our findings underscore the importance of investigating the cumulative health impacts of noise and other environmental burdens on these vulnerable communities to better inform policy.
