Developments in electrochemical sensors for occupational and environmental health applications.

This paper provides an overview of recent advances in electrochemical sensors for industrial hygiene monitoring applications. Currently available instrument technologies as well as new devices under development are both exemplified. Progress in ruggedization and miniaturization of electroanalytical devices has led to significant improvements for on-site monitoring applications, e.g. in harsh environments and in biological monitoring. Sensor arrays and modified electrodes offer considerable promise for improved electrochemical sensing, i.e. through multi-species detection and enhanced selectivity. On-site electroanalytical detection and measurement in the field may become more widely used for applications in occupational health monitoring.
