摘要
目的探讨普通煤和固硫煤燃烧后烟气中SO2含量降低的程度。方法观察使用不同型煤家庭的两组儿童生物学指标的变化。结果固硫煤燃烧后空气中SO2含量比普通煤降低5～7倍。两组儿童生物学指标SOD、LYS、α1-AT、淋巴细胞DNA受损率等两组间未见明显差别。结论固硫煤的固硫效果显著降低SO2对空气的污染，有推广应用价值，对机体健康潜隐形损害的保护作用有待进一步探讨和研究。
Objective To compare the differences of SO2 emitted from burning coal-biomass briquette and raw coal. Methods To observe changes of biological indexes of two groups of children whose family use coal-biomass briquette and raw coal respectively. Results It was found that the concentration of SO2 from burning raw coal was 5-7 times than that from burning coal-biomass briquette. But there was no significant difference of SOD, LYS, α1-AT and DNA damage of lymphocytes of children in two groups. Conclusion It is suggested that use of coal-biomass briquette can reduce the emission of SO2 greatly than that of raw coal. Coal-biomass briquette has good fixed-sulfur effect and should be used widely. It needs to do further research to find its protecting effect to latent harmfulness to health by less emission of SO2 from burning coal-biomass briquette.
