Junge relationships in measurement data for cyclic siloxanes in air

► The Junge relationship relates variability of pollutants in air to their lifetime. ► We found a Junge relationship in temporal variability of D5 measured in rural Sweden. ► We found a Junge relationship in spatial variability of D3, D4 and D5 measured in the GAPS network. ► Our field-derived lifetimes of D6, 8:2-FTOH and tri-PCBs are within a factor of 3 of lab Values.
