    Nitrate concentrations in 1,000 Norwegian lakes had doubled in less than a decade. Rivers in the northeastern United States and the majority of Europe have increased ten to fifteen fold over the last century. Reactive nitrogen can contaminate drinking water through runoff into streams, lakes, rivers, and groundwater.

  6. Nitrogen assimilation - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_assimilation

    Nitrogen assimilation is the formation of organic nitrogen compounds like amino acids from inorganic nitrogen compounds present in the environment. Organisms like plants, fungi and certain bacteria that can fix nitrogen gas (N 2) depend on the ability to assimilate nitrate or ammonia for their needs.

    Biological substances can experience leaching themselves, [2] as well as be used for leaching as part of the solvent substance to recover heavy metals. [6] Many plants experience leaching of phenolics, carbohydrates, and amino acids, and can experience as much as 30% mass loss from leaching, [5] just from sources of water such as rain, dew, mist, and fog.
