Pinus sylvestris as a bio-indicator of territory pollution from aluminum smelter emissions.

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 study demonstrates the efficiency of using Pinus sylvestris L. as a bio-indicator of polluting substances that enter the environment with the emission of a large aluminum smelter. Recent research has demonstrated that pollution from aluminum smelter emissions covers a vast territory. The highest content of polluting elements is registered at a distance of 3 km from the smelter, with maximum concentrations found in the industrial zone (0.5 km from the smelter). The farther from the aluminum smelter, the lower the amount of polluting elements in the needles, although the F level still exceeds the background values at a distance of about 60 km from the source, the levels of Zn, Pb, and Cd up to 50 km, S up to 40 km, and Fe and Cu up to 35 km mostly in north-eastern and south-eastern directions correlating with prevailing atmospheric transfer of the emissions. Pollution with polycyclic aromatic hydrocarbons (PAHs) is also most expressed at a distance of 3 km from the smelter, then it gradually decreases to coincide with background concentrations at a distance of more than 60 km. This is confirmed by changes in overall PAH content and in qualitative and quantitative compositions of individual PAHs. The greatest number of components (17 substances) has been found in samples from the territory of the plant area: phenanthrene, fluoranthene, pyrene, chrysene, acenaphthylene, acenaphthene, anthracene, fluorene, benz[а]anthracene, benz[b]fluoranthene, benz[k]fluoranthene, benz[а]pyrene, benz[е]pyrene, perylene, indeno[1,2,3-c,d]pyrene, benz[g,h,i]perylene, and dibenz[a,h]anthracene. The farther away from the plant, the lower the number of components detected in PAH fraction, mainly due to the fact that the concentrations of most toxic PAHs with five or six aromatic rings (benz[b]fluoranthene, benz[k]fluoranthene, benz[а]pyrene, benz[е]pyrene, perylene, indeno[1,2,3-c,d]pyrene, benz[g,h,i]perylene, dibenz[a,h]anthracene) fall below the method detection limit. High concentrations of benz[а]pyrene and perylene in pine needles at the territories adjacent to the aluminum smelter confirm the technogenic character of forest pollution by PAHs.
