This review and workshop summary examines the interactions of airborne materials with
environmental surfaces, particularly vegetative canopies. Key objectives were to:(1) review …

Aluminum is a common constituent of the earth's crust and is present in many rock and soil
forming minerals. In spite of its abundance Al (III) usually is not very soluble in water …

Because of the vast areal extent and high rates of organic matter production of peatlands,
such ecosystems have a significant but poorly quantified impact on large numbers of lakes …

Sphagnum-dominated peat bogs are naturally acid and cover perhaps 1% of the Earth's
land surface. The tem poral and spatial variations of pH in a peat-bog in the northern …

An ice core in south Greenland covering the period 1869 to 1984 was analyzed for oxygen
isotopes and chloride, nitrate, and sulfate concentrations. The data show that the" …

Major solute concentrations in wet deposition were measured for 115 individual events from
October 1988 to June 1990 at Lake Calado, Amazonas, Brazil. A continuous record from …

The hydrochemical responses to slash-and-burnagriculture in a small rainforest catchment
of thecentral Amazon were investigated for one year. Disturbances in the partially deforested …
