Impact of human alteration of the nitrogen cycle in the US on radiative forcing. Biogeochemistry 114 (1), 25-40.Pinder, R., W. Schlesinger, G. Bonan, N. Bettez, T. Greaver, W. Wieder, and E.A. Davidson, 31 2012: Impacts of Human Alteration of the Nitrogen Cycle in the US on ...
Each of these environmental effects can be magnified by the ‘nitrogen cascade’: a single atom of Nr can trigger a cascade of negative environmental impacts in sequence. Here, we provide an overview of the impact of Nr on the environment and human health, including an assessment of the ...
The availability of carbon from rising atmospheric carbon dioxide levels and of nitrogen from various human-induced inputs to ecosystems is continuously increasing; however, these increases are not paralleled by a similar increase in phosphorus inputs. T
“How humans impact the Carbon‚ phosphorus‚ and nitrogen cycles” Christine Richardson Environmental Science May 1‚ 2013 The carbon cycle is based on carbon dioxide which is a very important element because it is a part of all life. All living things are made of elements such as oxygen...
All these effects are due to oxidative stress; they impact various antioxidants [83]. A classic example of oxidative stress induction among pesticides is the action of dipyridyls such as paraquat. This compound enters the redox cycle and constantly generates ROS such as the superoxide anion and ...
Nitrogen (N) is an essential element for all biological tissues, and the N cycle is one of the main biogeochemical cycles that can have a substantial and wide-ranging impact on the ecological environment1,2,3. Human activities have greatly changed the global N cycle and increased the creation...
• Doubled the nitrogen and phosphorous in our soils in the past century with fertiliser use. This is likely to be the largest impact on the nitrogen cycle in 2.5bn years. •在过去的一个世纪里,肥料使用使土壤中的氮和磷增加了一倍。 这可能是25亿年来对氮循环的最大影响。
and slow-rate systems as a means of crop production in the arid regions of the world. Because of the potential impact of contaminants on underground drinking-water supplies, the fate of trace organics and pathogens have received increasing attention where rapid infiltration is used to supplement gr...

First, the impact analysis of a single climatic factor is carried out, and the optimal time-lag of each climatic factor on NDVI is accordingly determined. On the basis of the optimal lag, multiple regression is performed to calculate the corresponding coefficients, and the influence degree of di...
