Wet and dry depositions serve as important factors affecting the distributions, transport, and transfer of persistent organic pollutants (POPs) in atmosphere. On the one hand, wet and dry depositions can wipe out POPs, such as polybrominated diphenyl ethers (PBDEs) in the atmosphere, but on the other hand, these POPs become important source for contamination when they enter water, sediment, and soil. This paper summarized the worldwide study on dry and wet depositions of PBDEs in the atmosphere, including the composition of PBDEs in air and rain water, wet and dry deposition fluxes, scavenging ratio, and dry deposition velocity, etc. The wet and dry deposition patterns of PBDEs in the atmosphere were described for the first time using chemical partitioning space map (CPSM), and the comparison with the published data indicated that CPSM would properly describe the partitioning behavior for PBDEs-gaseous phase was major portion for BDE-47, and particulate phase the dominant for BDE-209 in both dry and wet depositions. A summary and future development on wet and dry deposition of PBDEs also have been provided
