The inter-flat transmission characteristics of gaseous pollutants were further assessed using wind tunnel experiments. The possible negative effects of cross-contamination related to natural ventilation were concerned. The pollutant dispersion routes were expanded from source side to different facades. The leeward and sideward units got high risks of being infected for windward sources in a single-sided ventilated building. Cross ventilation obviously suppresses vertical transmission of pollutants from windward sources.
