Polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) concentrations in the environment and blood of residents living near industrial waste incinerators in South Korea.
Article in International archives of occupational and environmental health, 2025. 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
objectivesIndustrial waste incinerators (IWIs) are the main sources of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), a group of persistent organic pollutants that include known carcinogens. However, data on PCDD/Fs exposure levels in the environment and among residents living near these facilities are insufficient. We aimed to identify PCDD/Fs exposure concentrations in the environment and blood of residents living near IWIs and examine factors affecting PCDD/Fs exposure.
methodsPCDD/Fs concentrations were systematically measured at the outlets of IWIs, as well as in the atmosphere, soil, and blood.
resultsPCDD/Fs concentrations at the IWIs outlets (0.00108–0.36039 ng I-TEQ/ Sm3) were below the emission standards established by the Persistent Organic Pollutants Control Act in Korea. The average PCDD/Fs concentration in the atmosphere of the exposure area (0.0242 pg I-TEQ/Sm3) was significantly higher (p < 0.05) than that in the control area (0.0073 pg I-TEQ/Sm3). The blood PCDD/Fs concentrations in residents from the exposure area (3.13 pg WHO-TEQ/g lipids) were higher than those from the control area (2.74 pg WHO-TEQ/g lipids). However, this difference was not statistically significant. In the exposure area, blood PCDD/Fs concentrations were significantly associated with recent meat consumption (p < 0.05) and showed a borderline increase with longer residence duration (p = 0.07).
conclusionThis study confirmed that the current concentrations of PCDD/Fs in the environment and the blood of residents living near IWIs were not high. However, given the potential health impacts of PCDD/Fs, even at low concentrations, sustained efforts to mitigate exposure are essential through continuous environmental monitoring and effective source control.
