Many potentially harmful chemicals released by industries and human activities can contaminate our water, soil, or air and further impact the environment and our health. Real-time and in situ monitoring of various contaminants such as pathogens, metals, radioisotopes, volatile organic compounds, crude oil, and agricultural chemicals in low concentration is mandatory in the fields of industrial plants, automotive technologies, health and medicine, air and water quality control, natural soil/land/sea, and so forth. Reliable sensing technologies with high performance are highly desirable to settle these issues. The types of sensors include, but are not limited to, optical sensors, electronic sensors, acoustic wave sensors, chemical sensors, and any new sensing materials based sensors. Sensitivity, selectivity, and limit of detection are several key parameters to evaluate the performance of sensors. We invite investigators to submit original research and review articles that will contribute to the sensors for environmental monitoring. We are particularly interested in articles exploring the current concepts in addressing key requirements for future sensing technology.

Potential topics include, but are not limited to:

• Design and fabrication of sensor platforms
• Sensor miniaturization
• Portable sensors
• New sensing materials and sensing schemes/mechanisms
• Theoretical studies in sensing mechanisms and principles
• Sensor sensitivity, selectivity, response time, and limit of detection
• Detection of pathogens in water
• Monitoring pollutant gases
• Inspection and monitoring of contaminated soil/land/sea
• Multitarget detection
