2.1 Inorganic Substance Monitoring for Early Diagnosis
The relevance in monitoring toxic volatile analytes arises from the
increasing human activities that, especially in the last decades,
caused the emission into the atmosphere of a wide range of pollut-
ants at high concentration levels. Among the inorganic gaseous pol-
lutants, nitrogen oxides (NO, NO ), carbon monoxide (CO), and
2
hydrogen sulfide (H S) are enumerated as the most toxic gases with
2
very harmful effects on human health. In addition to their toxic
effect on the human body, such gases are produced by specific cells
at low concentrations, and their antiviral and immunodefensive
