Chemical elements that are either present naturally in the soil or introduced by pollution are
more usefully estimated in terms of 'availability'of the element, because this property can be
related to mobility and uptake by plants. A good estimation of 'availability'can be achieved by
measuring the concentration of the element in soil pore water. Recent achievements in
analytical techniques allowed to expand the range of interest to trace elements, which play a
crucial role both in contaminated and uncontaminated soils and include those defined as …
