The dominant base cations (BC; ie, Ca 2+, Mg 2+, K+, and Na+) are important in buffering
soil and water acidity in both terrestrial and aquatic ecosystems. Ca 2+, Mg 2+, and K+ are …

China has been experiencing a rapid increase in nitrogen (N) deposition due to intensified
anthropogenic N emissions since the late 1970s. By synthesizing experimental and …

Nitrogen (N) deposition-induced soil acidification has become a global problem. However,
the response patterns of soil acidification to N addition and the underlying mechanisms …

Several hypotheses have been proposed to explain recent, widespread increases in
concentrations of dissolved organic carbon (DOC) in the surface waters of glaciated …

A transect of 68 acid grasslands across Great Britain, covering the lower range of ambient
annual nitrogen deposition in the industrialized world (5 to 35 kg Nha–1 year–1), indicates …

Anthropogenic nitrogen deposition over the past half century has had a detrimental impact
on temperate ecosystems in Europe and North America, resulting in soil acidification and a …

Relations among nitrogen load, soil acidification and forest growth have been evaluated
based on short‐term (< 15 years) experiments, or on surveys across gradients of N …

This paper discusses the evolution of science and policies to control acid rain in Europe and
the United States over the past several decades. Acid rain gained prominence in the late …

We compiled regional and continental data on inorganic nitrogen (N) in seepage and
surface water from temperate forests. Currently, N concentrations in forest waters are usually …

The main aim of the international UNECE monitoring program ICP Waters under the
Convention of Long-range Transboundary Air Pollution (CLRTAP) is to assess, on a …
