Atmospheric trace metals: global cycles and assessment of man's impact
TLDR
In this article, the authors presented global data for sources of atmospheric input for 20 trace metals, and the relative importance of natural and anthropogenic sources is assessed, where interference factors are calculated as (total anthropogenic emissions/total natural emissions) × 100.About:

Quantitative assessment of worldwide contamination of air, water and soils by trace metals
Jerome O. Nriagu,Jozef M. Pacyna +1 more
TL;DR: Calculated loading rates of trace metals into the three environmental compartments demonstrate that human activities now have major impacts on the global and regional cycles of most of the trace elements.

Plant responses to abiotic stresses: heavy metal‐induced oxidative stress and protection by mycorrhization
TL;DR: The present results indicate that mycorrhization stimulated the phenolic defence system in the Paxillus-Pinus mycorRhizal symbiosis and Plants in certain mycor rhizal associations are less sensitive to cadmium stress than non-mycorrhizal plants.
Journal ArticleDOI
A global assessment of natural sources of atmospheric trace metals
TL;DR: For most of the toxic metals, the natural fluxes are small compared with emissions from industrial activities, implying that mankind has become the key agent in the global atmospheric cycle of trace metals and metalloids as mentioned in this paper.

Elemental mass-balance of material carried by major world rivers

TL;DR: In this paper, an estimate of average river particulate matter (RPM) composition was based on analyses of more than 40 elements in the Amazon, Congo, Ganges, Magdalena, Mekong, Parana and Orinoco rivers, covering the whole spectrum of morphoclimatic features.

Evolution of sedimentary rocks
TL;DR: In this paper, it has been shown that recycling and evolution are complementary concepts and that the observed secular variations in relative proportions of lithologic types and in chemistry of sedimentary rocks were mostly given an evolutionary interpretation.

Chemical concentrations of pollutant lead aerosols, terrestrial dusts and sea salts in Greenland and Antarctic snow strata☆
TL;DR: In this article, the authors reported analyses of lead in annual ice layers from the interior of northern Greenland and in annual layers of ice from interior of the Antarctic continent, showing that lead concentrations increase from 0.200 γPb/kg ice today in north pole ice sheets, the sharpest rise occurring after 1940.
