a Spatial distribution of EPFRs concentration in sea spray samples. b Comparison of EPFRs concentration in different samples and sea spray samples in the DA region, where the concentration of EPFRs in combustion, illuminated combustion (I-C), traffic PM and urban PM are from other studies (Guo et al.13; and Zhang et al.11) and the orange front represents sea spray samples. c Comparison of EPFR concentration in size-resolved atmospheric PM, and the orange front represents sea spray samples.
