人类活动对铬生物地球化学循环的影响

Effects on the Biogeochemical Cycle of Chromium from Human Activities

通过建立2个简单的铬生物地球化学循环模型PM和CM,来说明人类工业活动对铬的生物地球化学循环的影响。通过对PM和CM的比较发现,人类的工业活动向陆地、海水和大气圈的输入通量,占其各自总输入通量的69.65%、56.96%和38.23%。

Two simple biogeochemical cycle models （PM and CM） were developed to demonstrate the influence of chromium on the biogeochemical cycle from human activities in this paper. By comparing PM and CM,we estimated that 69.65% of total land loading,56.96% of total ocean loading and 38, 23% of total atmosphere loading were emitted from human activities.
