在冬季(2006年11月至2007年2月)，对印度中北部城市和路边的10户家庭的室内和室外环境中的23种多环芳烃(PAHs)进行了同时测定。市区场地厨房、客厅和室外的总多环芳烃平均浓度分别为1946.84 ng/m(3)、1666.78 ng/m(3)和1212.57 ng/m(3)，而路边场地厨房、客厅和室外的平均浓度分别为2824.87 ng/m(3)、2161.26 ng/m(3)和3294.28 ng/m(3)。二环、三环和四环多环芳烃在气相中占主导地位，而五环、六环多环芳烃主要与颗粒相有关。两地室内和室外环境中多环芳烃的浓度变化趋势为：1-甲基萘&1-甲基萘&1-联苯和1-联苯；2-甲基-2-甲基萘和2-甲基萘；居室内PAHs总量的空间变化趋势为室外厨房起居室，路边居室为室外厨房起居室。相关分析被用来确定多环芳烃的来源。CO_2与客厅/室外(L/O)和厨房/室外(K/O)的PAHs总量的比值呈显著正相关。(C)2009爱思唯尔B.V.保留所有权利。
Twenty-three polycyclic aromatic hydrocarbons (PAHs) were measured simultaneously in indoor and outdoor environment of ten homes at urban and roadside sites in the north central part of India during winter season (November 2006 to February 2007). The average concentration of total PAH (TPAH) was 1946.84 ng/m(3) in kitchen, 1666.78 ng/m(3) in living room and 1212.57 ng/m(3) in outdoors at urban site, whereas at roadside site it was 2824.87 ng/m(3), 2161.26 ng/m(3), and 3294.28 ng/m(3) in kitchen, living room and outdoors respectively. The two, three and four ring PAHs were predominant in vapour phase, while the five, six ring PAHs were primarily associated with the particulate phase. The concentration trends of the PAHs in present study were naphthalene > 2-methylnaphthalene > 1-methylnaphthalene > biphenyl > acenaphthylene in indoor and outdoor environment of both the sites. The spatial trend of total PAHs concentrations in the house located at urban sites, was kitchen > living room > outdoors whereas at roadside site, the trend was outdoors > kitchen > living room. Correlation analysis has been used to identify the sources of PAHs. The correlation between CO2 and ratio of living room/outdoors (L/O) and kitchen/outdoor (K/O) of total PAHs concentration for two sites was found to be significant. (C) 2009 Elsevier B.V.
