Intermittent fever: Such fever occurs only in intervals. The temperature elevation is present only for a certain period‚ later cycling back to normal. e.g. malaria‚ kala-azar

The transfer of trace elements between soil and plant is part of chemical element cycling in the nature. The mobility and availability of trace elements are controlled by many factor of Climatic‚ biological and geochemical origins in nature. That means‚ to predict the uptake of trace elements by plants from soil it is important to look at several biotic and abiotic parameters the affect and control the behavior of elements in the soil. The risk to environment and human health of a given trace metals
