A．Almost-free internet phone calls herald the slow death of traditional telephony.

D．The dramatic shift in the te[ecoms industry has received little attention.

A、Speciation may be defined as the different physico-chemical forms of an element which together comprise its total concentration in a given sample.

B、Because the total concentration of a polluting element in an environmental sample provides no information concerning the fate of the element in terms of its interaction with sediment, its ability to cross biological membranes, or its resultant toxicity of a metal. Changes in speciation may dramatically affect the toxicity of a metal. Thus, in order to assess the environmental impact of an element, we must have some information concerning its speciation.

C、Some analyses can only be made at, or very close to, the sampling site.Readily portable and robust analytical equipment or remote sensing devices are thus required.

D、The main shortcoming to the computational approach is the reliability of the data used. The results of the model are only as good as the parameters on which they depend and any shortcomings in either the analytical concentration of the system under investigation or in the thermodynamic data will result in a very misleading speciation profile.
