Abstract
Two aspecific tests, suitable to be used as "alarm" tests, are proposed. In
particular, a sensor and a biosensor, both of the electrochemical type, were set
up, characterised and used to check the TOC value (total organic carbon) and the
toxicity of samples coming from the Piedimonte S. Germano (a small town in the
South of Lazio, Italy) water system. The sensor used to determine the TOC is
based on the measure, by a suitable modified commercial COz electrode, of the
carbon &oxide produced by a catalysed photodegradation of organic compounds.
The toxicity was tested by a respirometric test based on the measure, by a
commercial Clark electrode, of the oxygen consumed by yeast cells for their
breathing activity in presence and absence of the considered toxic. Both the
devices have demonstrated to be s
