Indoor Air Pollution Databases

The database contains data abstracted from more than 110 published papers with measurements of air quality in Chinese households, mostly from the Chinese literature previous to 1995. It is organized by pollutant (Particulates, Sulfur Dioxide, Carbon Monoxide, Nitrogen Oxides, Benzo[a]pyrene); fuel type (Coal & Mixed, Gas, Biomass); and location (Urban, Rural).

The database can be downloaded in two versions.

1. As a pdf file or on the WHO website page titled Indoor Air Pollution Database for China. This is the full report containing an introduction to the database tables, which describes the history of the database and the selection criteria for papers, as well as drawing conclusions about the overall pattern of indoor air pollution that it reveals in China.

2. As a Zip folder containing just the Excel spreadsheets for the main database tables and an  containing the full list of papers, key to the contents of each paper, and footnotes to the database.


The Global database of household air pollution measurements, commissioned and hosted by WHO and developed by researchers at Sri Ramachandra University, Chennai, India and the University of California at Berkeley, provides an overview of methods and results from 154 studies reporting household air pollution measurements. This database, with measurements from 37 countries, allows for comparisons within or across studies.

A description of the methods used to identify and extract data from the scientific studies, along with a description of the database architecture can be found in the following documents, both hosted at WHO:

WHO also hosts an updated version of its global Solid Fuel Use estimates. More information on how solid fuel use estimates are derived can be found at WHO’s indicator page. The database is available in WHO’s Solid Fuel Use Estimates Database.
