人们对长期接触硫化氢（H2S）对健康的影响知之甚少。新西兰罗托鲁瓦市由于其位于地热田上方而暴露于H2S。在这项研究中，作者将罗托鲁瓦的地区分为高、中、低硫化氢暴露区。使用1993-1996年的发病率数据，计算了神经系统、呼吸系统和心血管影响的标准化发病率。Poisson回归分析用于确认结果。结果显示了安全性-反应趋势，特别是对于神经系统疾病，但也对于呼吸系统和心血管疾病。混杂因素数据仅限于年龄、种族和性别。H2S暴露评估存在局限性。假设是，最近的接触代表长期接触，个人的全部接触是在家中接受的。这项研究的结果加强了H2S暴露对健康有慢性影响的建议。需要进一步调查。
Little is-known about health effects from chronic exposure to hydrogen sulfide (H2S). The city of Rotorua, New Zealand, is exposed to H2S by virtue of its location over a geothermal field. In this study, the authors classified areas within Rotorua as high-, medium, or low-H2S exposure areas. Using 1993-1996 morbidity data, standardized incidence ratios were calculated for neurological, respiratory, and cardiovascular effects. Poisson regression analysis was used to confirm results. Results showed exposure-response trends, particularly for nervous system diseases, but also for respiratory and cardiovascular diseases. Data on confounders were limited to age, ethnicity, and gender. The H2S exposure assessment had limitations. Assumptions were that recent exposure represented long-term exposure and that an individual's entire exposure was received at home. The results of this study strengthen the suggestion that there are chronic health effects from H2S exposure. Further investigation is warranted.
