Abstract

Polycyclic aromatic hydrocarbons (PAH) are organic pollutants ubiquitous in the aquatic environment. Considering the danger PAH-s pose to the health of aquatic organisms and humans, there is an increasing need for fast and reliable methods enabling early detection of these compounds in the environment. PAH-s influence the structure and organisation of a lipid layer electrostatically adsorbed on the surface of a mercury electrode, which can be monitored electrochemically using fast cyclic voltammetry. This work shows the development of an electrochemical sensor with a mercury microelectrode modified by a mixed lipid layer of phospholipids and triglycerides as a part of a semi-automated flow system for the early detection of polycyclic aromatic hydrocarbons in natural waters.
