Short-chain chlorinated paraffins (SCCPs) are of concern due to their 
potential for adverse health effects, bioaccumulation, persistence, and 
long-range transport. Data on concentrations of SCCPs in urban areas and
 underlying emissions are still scarce. In this study, we investigated 
the levels and spatial distribution of SCCPs in air, based on two 
separate, spatially resolved sampling campaigns in the city of Zurich, 
Switzerland. SCCP concentrations in air ranged from 1.8 to 17 ng·m–3 (spring 2011) and 1.1 to 42 ng·m–3 (spring 2013) with medians of 4.3 and 2.7 ng·m–3,
 respectively. Both data sets show that atmospheric SCCP levels in 
Zurich can vary substantially and may be influenced by a number of 
localized sources within this urban area. Additionally, continuous 
measurements of atmospheric concentrations performed at one 
representative sampling site in the city center from 2011 to 2013 showed
 strong seasonal variations with high SCCP concentrations in summer and 
lower levels in winter. A long-term dynamic multimedia environmental 
fate model was parametrized to simulate the seasonal trends of SCCP 
concentrations in air and to back-calculate urban emissions. Resulting 
annual SCCP emissions in the city of Zurich accounted for 218–321 kg, 
which indicates that large SCCP stocks are present in urban areas of 
industrialized countries.
