本文总结了本教研室五年来室内燃煤污染的研究成果,从民用型煤与煤气污染物排放特征,及其对居民的健康负荷进行了论述。在健康负荷方面通过不同燃料燃烧排放的颗粒物浓度-毒性-致突变性,COHb形成量,对居民呼吸道患病率和症状率的影响及对儿童免疫指标的影响等诸指标或指数,并给予不同的权重,综合建立了健康负荷指数(Health StressIndex)。结果表明燃煤户的HSI为燃气户的4.34倍。为实现城市煤气化提供了卫生学依据。
This article summarizes the research results of indoor coal combustion in the past five years, and discusses the discharge characteristics of civil coal and gas pollutants and their health load on residents. Differences in indicators such as concentration of pollutants - toxicity - mutagenicity, formation of COHb, prevalence and symptoms rate of respiratory tract in residents, and impact on children’s immune index in terms of health load through different fuel combustion and other indicators and indices Of the weight, the establishment of a comprehensive health load index (Health StressIndex). The result shows that the HSI of coal-fired households is 4.34 times that of gas households. To provide a city of gasification hygiene basis.
