The accumulation of phosphorus in the environment as a risk to eutrophication of water and terrestrial ecosystems and human health

摘要

The most intensive phosphorus flux in environment occurs within the human food chain. Almost the full amount of phosphorus mined from its geological deposits is going into this chain. The greatest discrimination in its flux has place in the agriculture. Only few per cent of phosphorus inputs into agriculture hits to household, the remainder is left in the cropped soils or dispersed into the environment. Similarly, roughly all phosphorus from household, including also this from cleaning agents, is dispersed into environment. Phosphorus is a conservative element, once put into environment is accumulating there. Phosphorus cannot be removed from environment, it may be merely transferred between different ecosystems. The apparent phosphorus sink are the oceans, through its load running off makes simply few per cent of that mined from geological deposits.
