TL;DR: In this article, a general picture of the biogeochemical cycling of HCOOH and CH 3 COOH is beginning to emerge, and the similarity of concentrations in remote and impacted regions indicates that anthropogenic emissions of carboxylic acids or precursors are probably not important sources over broad geographic areas.

TL;DR: In this paper, atmospheric sulfur budgets for the eastern United States, eastern Canada and eastern North America are formulated, based on the fluxes: natural and man-made emissions, wet and dry deposition and atmospheric inflows and outflows.

TL;DR: In this paper, the authors modeled carbon and nitrogen biogeochemical cycles in croplands of China (and, for comparison, the United States) to estimate the annual soil organic carbon (SOC) balance for all cropland.

TL;DR: This paper discussed the quantitative model used to estimate patterns and absolute time scales of surface water acidification, called MAGIC (model of acidification of groundwater in catchments), based on mathematical representations of those processes thought the preliminary catchment controls on acidification.

TL;DR: The global nitrogen cycle at the beginning of the 21st century has been shown to be strongly influenced by the inputs of reactive nitrogen (Nr) from human activities, including combustion-related NOx, industrial and agricultural N fixation, estimated to be 220 Tg N yr−1 in 2010, which is approximately equal to the sum of biological N fixation in unmanaged terrestrial and marine ecosystems.
