Capillary and microchip electrophoretic analysis of polycyclic aromatic hydrocarbons

Area of Science:

• Environmental Chemistry
• Analytical Chemistry
• Toxicology

Background:

• Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants.
• PAHs pose significant health risks due to their high toxicity.
• Regulatory bodies like the US EPA and EFSA classify PAHs as priority pollutants.

Purpose of the Study:

• To address the urgent need for sensitive, rapid, and cost-effective PAH detection methods.
• To review and critically evaluate existing literature on PAH analysis.
• To explore the potential of electrophoresis techniques for PAH identification.

Main Methods:

• Review of published literature on capillary electrophoresis (CE) for PAH analysis.
• Discussion of microchip electrophoresis (MCE) approaches for PAH detection.
• Critical assessment of the sensitivity, speed, and cost-effectiveness of CE and MCE methods.

Main Results:

• Electrophoresis techniques, including CE and MCE, show promise for PAH analysis.
• These methods offer attractive features for detecting PAHs in complex matrices.
• The review consolidates current knowledge on electrophoretic approaches for PAH identification.

Conclusions:

• Capillary and microchip electrophoresis are valuable tools for the sensitive and efficient analysis of PAHs.
• Further development of these techniques can meet the demand for rapid and affordable PAH detection.
• Electrophoresis offers a viable solution for monitoring PAHs in environmental and food safety applications.
