Determination of formaldehyde and cyanide ion in human nasal discharge by using simple spectrophotometric methods

Abstract

Environmental tobacco smoke (ETS) contains many toxic compounds which include substances classified as aldehydes (e.g. formaldehyde) and inorganic substances such as cyanide ions. The information on the determination of these compounds in water is available, but the monitoring data on the level of these substances in human body fluids are still lacking. In this work the procedure for determining cyanide ions and formaldehyde in samples of human nasal discharge by simple spectrophotometric technique is presented. © 2012 Versita Warsaw and Springer-Verlag Wien.
