Globalisation and industrialisation have led to tremendous expulsion of wide range of pollutants. These pollutants result in causing high level of health issues like chronic, acute and sometimes lethal. Monitoring and assessment of these pollutants is pertinent for the proper sequestration. The present equipments for environmental monitoring have the problems associated with sample handling, complex morphology and system portability. This has lead to an advanced level of research like microfluidics, integrates various assay reaction procedures and monitoring techniques in a palm. Microfluidics offers numerous advantages like high mass transfer coefficient, better reaction rate, low reactant utility, less wastage of chemicals, portability etc. With these significant properties, microfluidic devices are best suited for environmental analyses.
