Persistent, Mobile, Toxic: The Effects of Chemical Warning Labels on Public Risk Perception.
Article in Environmental science & technology letters, 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
Persistent, mobile, and toxic (PMT) chemicals, such as per- and polyfluoroalkyl substances (PFAS), pose significant environmental and health risks. Public risk perception is an important driver of change in regulation and consumption patterns. Previous research has investigated the effect of toxicity information, but little is known about public perception of chemical properties such as persistence or mobility alone or in combination with toxicity. In this study, 328 participants rated one of two everyday products in terms of affect, concern, and policy support. Labels indicated the presence of persistent (P), mobile (M), and toxic (T) chemicals either in isolation or combined (PM, PT, MT, and PMT), compared to a control with no label. When labels indicated only a single chemical property, toxicity elicited the strongest risk response, and this was amplified for products with high body contact (dental care) compared to low body contact (household cleaner). Labels warning of all three properties together (PMT) triggered the strongest risk response while demonstrating a nonadditive relationship. These findings suggest that the public is sensitive to warnings about different chemical properties beyond toxicity. Informing the public of diverse chemical properties has the potential to change behavior and encourage support for stricter regulation.
