Electroanalytical applications in occupational and environmental health

Abstract

Electroana1:Tical chemistry has been used for years in the occupational and environmental health fields. Portable sensors and analytical devices based on electrochemical (EC) methods are commonly used on-site in the workplace. Laboratory EC methods also have been used extensively for the analysis of industrial hygiene and related samples. Recent advances in electroanal>-tical methodolog may lead to new analytical applications in the occupational health arena, both in the laboratory as well as on-site in the xvorkplace. Applications in heavy metals analysis, analysis for inorganic and organic species, and bioanalysis are exemplified. This article provides an overview of the history of EC analysis for industrial hygiene purposes, and also summarizes current and newly developed applications of electroanaljdcal methods in occupational and environmental health.

Electroanalytical Detection of Cr(VI) and Cr(III) Ions Using a Novel Microbial Sensor

“…Hexavalent chromium (Cr(VI)) compared to trivalent chromium (Cr(III)) is a potent carcinogen . Among the various analytical techniques in vogue, voltammetry has several advantages such as its portability, low detection limits, faster detection of analytes and requirement of very less amount of solvents and reagents, when compared to other analytical methods such as UV‐Vis spectrophotometric analysis, Atomic Absorption Spectrophotometer (AAS), Inductively Coupled Plasma‐Atomic Emission Spectrophotometry (ICP‐AES), High Pressure Liquid Chromatography (HPLC) and hybrid detection methods involving combinations of the above mentioned techniques .…”

Electrochemical sensing of gases based on liquid collection interfaces

“…In a polarographic method for formaldehyde approved by the U. S. Occupational Safety and Health Administration (OSHA), a known volume of air is drawn through a bubbler containing 10 % methanol in water [36]. The captured formaldehyde is reacted with hydrazine to form the hydrazone.…”

A Mercury‐Free Sensor to Control Trace Metal Ionization Used to Treat Pathogens in Water Distribution Systems

“…Among the other analytical techniques, electrochemical methods, and especially stripping voltammetry, are currently considered particularly attractive for on-site analysis of heavy metals at the mg/L level [7][8][9][10].
