Uncovering the Hidden Dangers: The Elusive 98% of Chemical Exposure

A meta-analysis of non-targeted analysis (NTA) studies conducted over the past six years estimates that less than 2% of all chemicals have been identified, highlighting the need for a more proactive approach to chemical monitoring and management. Current monitoring programs target only a fraction of known chemicals, leaving a vast number of chemicals unknown. The study also identified areas for improvement in NTA methods, including sample preparation and data acquisition. Researchers advocate for the development of more versatile analytical technologies and effective data analysis protocols to better understand the true chemical space of exposure.
