1、济南市PM2.5与人体相关疾病发病率的关联性研究［摘要］目的研究济南市空气屮PM2.5与临床呼吸科、心内科和神经内科门诊量的关系。方法收集济南市两家综合性医院一年呼吸科、心内科和神经内科门诊量、空气质量及气象数据，在控制“星期几效应”、气象因素等混杂因素的基础上，运用广义相加泊松冋归模型分析了PM2.5对英的影响。结果在两日累积PM2.5小于200ug/m3时，随着PM2.5的增加，呼吸科门诊量增加并不大，当其大于200Pg/m3且小于400Pg/m3时，门诊量增加较大，大气中PM2.5浓度与呼吸科日

2、门诊量间存在非线性关系。两FI累积PM2.5浓度与心内科和神经内科门诊量呈线性关系，两口累积PM2.5每增加1Pg/m3,两医院心内科、神经内科门诊量大约增加1例患者。结论随着空气中PM2.5浓度的增加，临床呼吸科、心内科和神经内科门诊量冇增加趋势，但PM2.5浓度与不同科室日门诊量关系稍有不同。［关键词］PM2.5；临床常见疾病；广义可加模型［中图分类号］R195.1［文献标识码］B［文章编号］1673-9701(2015)16-0114-04［Abstract］ObjectiveTostudyth
