Household fine particulate matter (PM ) pollution greatly impacts residents' health. To explore the current national situation of household PM pollution in China, a study was conducted based on literature published from 1998 to 2018. After extracting data from the literature in conformity with the requirements, the nationwide household-weighted mean concentration of household PM (HPL) was calculated. Subgroup analyses of spatial, geographic, and temporal differences were also done. The estimated overall HPL in China was 132.2 ± 117.7 μg/m . HPL in the rural area (164.3 ± 104.5 μg/m ) was higher than that in the urban area (123.9 ± 122.3 μg/m ). For HPLs of indoor sampling sites, the kitchen was the highest, followed by the bedroom and living room. There were significant differences of geographic distributions. The HPLs in the South were higher than the North in four seasons. The inhaled dose of household PM among school-age children differed from provinces with the highest dose up to 5.9 μg/(kg·d). Countermeasures should be carried out to reduce indoor pollution and safeguard health urgently.
家庭细颗粒物（PM）污染对居民健康影响巨大。为了探究中国家庭 PM 污染的现状，本研究基于 1998 年至 2018 年发表的文献进行。对文献进行数据提取并按照要求进行整合后，计算了全国家庭 PM（HPL）的加权平均值。同时还进行了空间、地理和时间差异的亚组分析。中国的 HPL 估计值总体为 132.2±117.7μg/m³。农村地区的 HPL（164.3±104.5μg/m³）高于城市地区（123.9±122.3μg/m³）。对于室内采样点的 HPL，厨房最高，其次是卧室和客厅。地理分布存在显著差异。四个季节中，南方的 HPL 均高于北方。学龄儿童的家庭 PM 吸入剂量因省份而异，最高剂量可达 5.9μg/（kg·d）。应采取措施紧急降低室内污染，保障健康。
