| Abstract |
The arctic has been contaminated by legacy organochlorine pesticides (OCPs) and currently used pesticides (CUPs) through atmospheric transport and oceanic currents. Here we report time trends and air-water exchange of OCPs and CUPs from research expeditions conducted between 1993-2013. Compounds determined in both air and water were trans- and cis-chlordanes (TC, CC), trans- and cis-nonachlors (TN, CN), heptachlor exo-epoxide (HEPX), dieldrin (DIEL), chlorobornanes (ΣCHBs, toxaphene), dacthal (DAC), endosulfans and metabolite endosulfan sulfate (ENDO-I, ENDO-II, ENDO SUL), chlorothalonil (CHT), chlorpyrifos (CPF) and trifluralin (TFN). Pentachloronitrobenzene (PCNB, quintozene) and its soil metabolite pentachlorothianisole (PCTA) were also found in air. Concentrations of most OCPs declined in surface water, whereas some CUPs increased (ENDO-I, CHT and TFN) or showed no significant change (CPF, DAC), while most compounds declined in air. Chlordane compound fractions TC/(TC+CC) and TC/(TC+CC+TN) decreased in water and air, while CC/(TC+CC+TN) and TN/(TC+CC+TN) increased, suggesting selective removal of more labile TC over time and/or a shift in chlordane sources. Water/air fugacity ratios indicated net volatilization (FR >1.0) or near equilibrium (FR not significantly different from 1.0) for most OCPs, but net deposition (FR <1.0) for ΣCHBs. Net deposition was shown for ENDO-I on all expeditions, while the net exchange direction of other CUPs varied. Understanding the processes and current state of air-surface exchange helps to interpret environmental exposure, evaluate the effectiveness of International Protocols and provides insights for the environmental fate of new and emerging chemicals. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 August 2015.
All research outputs
#22,760,732
of 25,377,790 outputs
Outputs from Environmental Science & Technology
#19,590
of 20,675 outputs
Outputs of similar age
#237,906
of 277,645 outputs
Outputs of similar age from Environmental Science & Technology
#263
of 291 outputs
Altmetric has tracked 25,377,790 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 20,675 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 17.8. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 277,645 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 291 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
