Atmospheric transport and deposition of PFAS in East Antarctica: Evidence from snow transect measurements and a multidecadal record.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The occurrence of per- and polyfluoroalkyl substances (PFAS) in Antarctica has been previously reported; however, the mechanisms of their inland penetration and the interplay between their depositional histories and interhemispheric transport remain unclear. Here, PFAS in snow along a transect across East Antarctica (from Zhongshan Station to Dome A) and depositional records at Dome A were studied to elucidate the sources and transport of PFAS and to reconstruct the historical emission record. Our findings suggest that precursor degradation and sea spray aerosol are the main sources of PFAS and play a pivotal role in the regional and seasonal variability of PFAS accumulation. The half-century depositional records reveal connections between Antarctica and distant sources. We propose the hemispheric and interhemispheric transport of PFAS from source regions to Antarctica, where they are deposited.
