A given N containing molecule can in fact contribute successively to different environmental problems, this is referred to as the cascade effect . Reactive forms of nitrogen are also often readily soluble in water and or occur in the gas phase, making them very mobile. As a consequence, an excess of Nr can have an impact on the environment relatively quickly.
