Microfluidic systems have advanced beyond natural and life science applications and lab‐on‐a‐chip uses. A growing trend of employing microfluidic technologies for environmental detection has emerged thanks to the precision, time‐effectiveness, and cost‐effectiveness of advanced microfluidic systems. This paper reviews state‐of‐the‐art microfluidic technologies for environmental applications, such as on‐site environmental monitoring and detection. Microdevices are extensively used in collecting environmental samples as a means to facilitate detection and quantification of targeted components with minimal quantities of samples. Likewise, microfluidic‐inspired approaches for separation and treatment of contaminated water and air, such as the removal of heavy metals and waterborne pathogens from wastewater and carbon capture are also investigated.

“…Also, a piezo valve made with a silicone diaphragm and PDMS blocks was developed and the flow was maintained at a constant rate by the chemically compatible piezo valve and assistance of the micro flow sensor. Another challenge is in situ calibration of GAS [57,59]. A honeycomb microchannel device can be used as a gas scrubber and as a gas desorber.…”
