Particulate matter (PM) pollution from pig farms is of increasing environmental concern due to the rapid development of intensively managed pig farms worldwide. However, information on this topic is scarce in China to date. Therefore a two-year study to monitor the dynamics of total suspended particles (TSP) and particulate matter with diameter less than 10 µm (PM 10 ) and their soluble ions was conducted at an industrial pig farm near Beijing. In total, two fattening pig houses were sampled during three fattening periods from 2010 to 2011. Daily mean indoor TSP and PM 10 concentrations were 1.85 and 0.63 mg m -3 on average.
