Twenty-Five Years of Research and Monitoring Using PUF Disk Passive Air Samplers.
Review in Environmental science & technology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
For the past quarter century, polyurethane foam (PUF) disk-based passive air samplers (PASs) have grown as a pivotal tool in research and monitoring of persistent organic pollutants and emerging chemicals in ambient air in both the gas phase and on ambient particulate matter. Their low cost and ease of use have facilitated deployment at the regional and global scales. Modifications to the PUF-PAS have expanded its use for more specific purposes, such as the sorbent-impregnated PUF-PAS (SIP-PAS), which improves sorptive capacity for more volatile chemicals, and the passive dry deposition (PAS-DD) sampler, which captures larger particles and enables estimation of gas and particle deposition. This review summarizes studies characterizing uptake rates and partition coefficients of PUF disks for a wide range of compounds and evaluations of sampler design and performance. It synthesizes applications of PUF-PAS, SIP-PAS, and PAS-DD from 2000 to 2024 across diverse topics: ambient air measurements, indoor air quality, source emissions, health, and, most recently, biodiversity. Approximately 650 publications employing PUF disk-based PASs are summarized herein, demonstrating their increasing use and diversification. On the horizon, we envisage that the PUF-PAS will continue to transform and integrate fields of science and inform policy.
