Bioaccessibility and health risk assessment of Pb and Cd in urban dust in Hangzhou, China.
Article in Environmental science and pollution research international, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Heavy metals in urban dust can enter the human body through a variety of ways, thus endangering human health. Understanding the bioaccessibility of heavy metals in urban dust is a key to its risk assessment. After the G20 summit in 2016, Hangzhou city has received much attention, including its environmental health risk. The surface dust collected from three different functional areas in Hangzhou were subjected to the in vitro physiologically based extraction test (PBET) to measure the bioaccessibility of Pb and Cd. In terms of spatial variation, the distribution of Pb bioaccessibility was in the order of residential areas > city parks > main roads > the Botanic Garden, while for Cd ordered in city parks > residential areas > main roads > the Botanic Garden. For temporal variation, the bioaccessibility of Pb was higher in autumn and winter, and the bioaccessibility of Cd was higher in spring and autumn. Based on multiple linear statistical analysis, the relationship between the spatial and temporal distribution differences of the bioaccessibility of Pb and Cd in the city and the main components was discussed. Meanwhile, the non-carcinogenic hazard quotients of Pb and the carcinogenic risk of Cd were calculated and showed no harm to human health, except the total Pb in the surface dust with a high non-carcinogenic risk for infants. Urban dust in Hangzhou city has a slight pollution and health risk from Pb. Currently, controlling and reducing the city's Pb emission is the key to maintain Hangzhou city's air quality and matching with its international tourism city.
