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 CO(2) 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.
在印度中北部的城市和路边地区的 10 所住宅中，于冬季（2006 年 11 月至 2007 年 2 月）同时测量了室内和室外环境中的 23 种多环芳烃（PAHs）。城市地区厨房、客厅和室外空气中总多环芳烃（TPAH）的平均浓度分别为 1946.84ng/m(3)、1666.78ng/m(3)和 1212.57ng/m(3)，而路边地区厨房、客厅和室外空气中 TPAH 的浓度分别为 2824.87ng/m(3)、2161.26ng/m(3)和 3294.28ng/m(3)。在气相中，主要存在双环和三环 PAHs，而在颗粒相中，主要存在五环和六环 PAHs。本研究中 PAHs 的浓度趋势为萘>2-甲基萘>1-甲基萘>联苯>苊烯，在两个地区的室内和室外环境中均如此。位于城市地区的房屋中总多环芳烃浓度的空间趋势为厨房>客厅>室外，而在路边地区，趋势为室外>厨房>客厅。相关性分析已用于确定 PAHs 的来源。在两个地点，CO(2)与总多环芳烃浓度的客厅/室外（L/O）和厨房/室外（K/O）比值之间的相关性被发现是显著的。
