New study charts the fate of chemicals affecting health and the environment

(Arizona State University) In a new study, Rolf Halden, PhD, a researcher at Arizona State University's Biodesign Institute, examines the trajectory of chemicals appearing as emergent threats to human or environmental health. Halden's meta-analysis of 143,000 peer-reviewed research papers tracks the progress of these chemicals of emerging concern, revealing patters of emergence from obscurity to peak concern and eventual decline, over a span of 30 years.
