Abstract:

室内空气污染对人体健康威胁逐渐加重,而我国农居室内空气中颗粒物和CO对农户危害较为突出,目前该领域全面和深入的研究鲜有报道.2009年7月~2011年1月,调研了湖北、河北、辽宁、贵州和广东等5个省份共74户农村家庭,其中实时监测了58户家庭在不同燃料(生物质、蜂窝煤、液化气和沼气)和炉灶类型(开放式柴灶、传统灶、节柴灶)下,其室内PM1.0,CO,CO2和风速、温度等浓度和数据.通过分析数据发现,农户在炊事期间,燃料点火开始其室内PM1.0和CO浓度迅速升高,熄火后浓度缓慢下降;不同燃料、炉灶类型及其他环境因素都会对污染物浓度产生较大影响;在不同燃料类型下,农户室内PM1.0和CO之间的相关关系不同,且相关关系随二者浓度降低而减弱.
