This presentation will highlight three major recent developments in air VOC testing methods and technologies in the United States as of 2025. Key updates include advancements in the detection and monitoring of per- and polyfluoroalkyl substances (PFAS), ethylene oxide (EtO), and breath air analysis. The talk will also provide insights into ongoing research directions and recent updates from the United States Environmental Protection Agency (USEPA), particularly in research and development (R&D) initiatives. Special attention will be given to emerging regulations related to fenceline monitoring, emphasizing their implications for environmental compliance and public health protection.
Dr. Gesheng Dai, a Chinese-American scholar, earned his Ph.D. in Engineering from East China University of Science and Technology in 1985. With over 40 years of experience in teaching, research, and experimentation in air monitoring (including VOCs), he has dedicated recent years to introducing globally proven VOC analysis and detection practices to China while contributing to the development of related standards.
From 1985 to 1988, he co-founded the Department of Applied Chemistry at Shenzhen University, serving as its Chair. As the lead expert, he directed Shenzhen's first industrial pollution source survey and testing project.
From 1988 to 1992, he was a Visiting Professor and Doctoral Advisor at the New Jersey Institute of Technology. He oversaw the VOC monitoring segment of New York’s Staten Island air pollution monitoring program and participated in comparative studies and standard development for US EPA’s air VOC testing methods (TO-14, TO-15, and TO-17).
From 1992 to 1998, he served as Laboratory Director of Air Pollution Monitoring at PACE Company (USA), managing air quality testing across its 28 U.S. laboratories and advising on air monitoring projects in Mainland China and Hong Kong.
In 1998, he founded Nutech Instruments, Inc., where he currently holds the position of chief technical manager.
