目的 研究天津市大气气态污染物二氧化硫(SO2)和二氧化氮(NO2)与城区居民每 日死亡问的相关性。方法 收集天津市城区2005-2007年大气丰要污染物[SO2、NO2和可吸入 颗粒物(PM10)]日平均浓度、日平均气温和相对湿度以及每日死冈别死亡人数,采用广义相加模 型,控制长期和季节趋势、气温和相对湿度等气象因素的影响,探讨SO2和NO2日平均浓度与每Et 死因别死亡问的相关性,分析PM10及模型参数对其相对危险度估计的影响。结果 大气SO2和 NO2与人群每日非意外死亡和循环系统疾病死亡问显著相关,与呼吸系统疾病问无显著关联。 SO2浓度每升高10 1.tg/m3,人群非意外死亡和循环系统疾病死亡分别增加0.56%(0.23%~0.89%) 和0.49%(0.06%一0.93%);NO2浓度每升高10 Ixedm3,人群非意外死产和循环系统疾病死亡分别增 加0.94%(0.17%~1.70%)和1.29%(0.29%~2.30%)。结论 天津市大气SO2和NO2污染与城区居 民每日非意外死亡和循环系统疾病死亡显著相关。 |

Objective To study the association between sulphur dioxide,nitrogen dioxide and dailv mortality in urban population from Tianjin.Methods Data on daily concentration of inhalable particulate maRer.sulphur dioxide and nitrogen dioxide,daily mean temperature and relative humidity.daily cause.specific death countS were collected.Generalized additive models was used to explore the relationship between sulphur dioxide,nitrogen dioxide and daily mortality,after adjusting the eriects of long-term and seasonal trend.weather conditions。and to analyze the potential efrect of particulate matter and model parameters on relative risk estimates.Results Results showed mat the daily concentrations of S02 and N02 were significantly associated with daily non-accidental and cardiovascular mortality but not associated with daily respiratory mortalitY.An increase of 1 0 LL g/m3 in S02 was associated with 0.56%(95%C,:0.23%-0.89%)non-accidental morality,0.49% (0.06%-0.93%)cardiovascular morality,respectively.An increase of 10ug/m‘in N02 was associated with 0.94%(95%C/:0.1 7%-1.70%)non.accidental morality。1.29%(0.29%-2.30%)cardiovascular morality.respectively.Conclusion Our findings suggested that exposure to S02 and N02 was significantly associated with daily cardiovascular and respiratory mortality in urban population in Tianjin. |
