Some perspectives of the major biogeochemical cycles.

摘要: Presents the results of symposium Scientific Committee on Problems Environment (SCOPE). Examines biogeochemistry globe from a holistic point view, considering alteration global cycles and distortion by human activities. Focuses flux reservoir amounts individual substances such as carbon, nitrogen, phosphorus, sulfur water. Illustrates urgency for quantitative answers relative to changes in atmospheric emissions sulfur, nitrogen due increased combustion fossil fuels. Shows how these perturbations affect variety other them, all combining welfare.
