Using isotopic lead and strontium in sediments to trace natural and anthropogenic sources in the Bohai Sea.

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 containment history in the coastal zone of the Bohai Sea has not been sufficiently traced because of the difficulty in identifying complex sources of pollutants. This study quantitatively identified various sources of Pb and Sr in two tidal flat sediment cores from Bohai Bay (core BB) and Liaodong Bay (core LB) based on their isotope ratios to trace the natural and anthropogenic disturbance history in the Bohai Sea. The results showed that natural inputs of Pb were the main sources for cores BB and LB; however, core LB was more influenced by anthropogenic inputs. Natural inputs were derived mainly from Chinese loess and Yellow River sediments, whereas anthropogenic sources were mainly a mixture of vehicular exhaust emissions before 2000 and coal combustion after 2000. Anthropogenic influence has declined since the late 1990s, especially in Bohai Bay, but has increased in Liaodong Bay from 1998 to 2006.
