对室内空气污染的科学认识主要基于在高收入国家（HIC）城市进行的研究。对于中低收入国家（LMICs）城市中污染物浓度在一天中的变化情况知之甚少。了解直径小于2.5微米的细颗粒物（PM2.5）浓度在一天中室外（在一系列国家）和室内（使用孟加拉国达卡的测量值）的变化。作为MCLASS II（孟加拉国穆斯林社区了解二手烟）项目的一部分，从达卡的779个家庭收集了PM2.5浓度数据，并将其与室外PM2.5浓度进行比较，以确定暴露于空气污染的时间变化。14个中低收入国家的23个城市以及伦敦（英国）、巴黎（法国）和纽约（美国纽约州）的每小时PM2.5数据是从公开来源提取的，以供比较。达卡家庭中的PM2.5表现出与室外测量相似的时间模式，夜间浓度高于下午。这种模式在23个LMIC城市中的19个城市也很明显。在达卡，PM2.5浓度在晚上比下午高。中低收入国家PM2.5的日变化很大，比伦敦、巴黎或纽约的变化大。这对公共卫生界处理中低收入国家空气污染对健康影响的方法具有影响。
Scientific understanding of indoor air pollution is predominately based on research carried out in cities in high-income countries (HICs). Less is known about how pollutant concentrations change over the course of a typical day in cities in low- and middle-income countries (LMICs). To understand how concentrations of fine particulate matter smaller than 2.5 microns in diameter (PM2.5) change over the course of the day outdoors (across a range of countries) and indoors (using measurements from Dhaka, Bangladesh). Data on PM2.5 concentrations were gathered from 779 households in Dhaka as part of the MCLASS II (Muslim Communities Learning About Second-hand Smoke in Bangladesh) project, and compared to outdoor PM2.5 concentrations to determine the temporal variation in exposure to air pollution. Hourly PM2.5 data from 23 cities in 14 LMICs, as well as London (UK), Paris (France) and New York (NY, USA), were extracted from publicly available sources for comparison. PM2.5 in homes in Dhaka demonstrated a similar temporal pattern to outdoor measurements, with greater concentrations at night than in the afternoon. This pattern was also evident in 19 of 23 LMIC cities. PM2.5 concentrations are greater at night than during the afternoon in homes in Dhaka. Diurnal variations in PM2.5 in LMICs is substantial and greater than in London, Paris or New York. This has implications for public health community approaches to health effects of air pollution in LMICs.
