We evaluated the acute health effects of a strong emission of malodorous sulfur compounds released from a pulp mill in South Karelia, Finland. The 24-hour ambient air concentrations of hydrogen sulfide for the two emission days were 35 and 43 micrograms/m3 (maximum 4-hour 135 micrograms/m3). A questionnaire was distributed after the high exposure and later after a low exposure period to 29 households with 75 subjects living in the nearby community. During the high exposure, 63% of the respondents reported experience of at least one symptom compared to 26% during the reference period. Every third participant reported difficulties in breathing. In the 45 subjects responding to both questionnaires more eye, respiratory and neuropsychological symptoms occurred during the exposure compared to the reference period. The strong malodorous emission from a pulp mill caused an alarming amount of adverse effects in the exposed population.
我们评估了芬兰南卡累利阿一家纸浆厂排放的强烈恶臭硫化合物对健康的急性影响。在两次排放日，硫化氢的24小时环境空气浓度分别为35和43微克/立方米（4小时最高值为135微克/立方米）。在高暴露期之后以及随后的低暴露期之后，向附近社区的29户家庭、75名居民发放了问卷。在高暴露期，63%的受访者报告至少出现一种症状，而在参照期这一比例为26%。每三名参与者中就有一人报告呼吸困难。在45名对两份问卷都做出回应的受试者中，与参照期相比，暴露期间出现了更多眼部、呼吸道和神经心理症状。纸浆厂强烈的恶臭排放对暴露人群造成了数量惊人的不良影响。
