Temporal trends in phthalate exposures: findings from the National Health and Nutrition Examination Survey, 2001–2010

23 January 2014

Phthalates are ubiquitous environmental contaminants. Because of potential adverse effects on human health, butylbenzyl phthalate (BBzP), di-n-butyl phthalate (DnBP), and di(2-ethylhexyl) phthalate (DEHP) are being replaced by substitutes including other phthalates, however little is known about consequent trends in population-level exposures. The study shows that US population exposure to phthalates has changed in the last decade. Trends varied by subpopulations for certain phthalates. Data gaps make it difficult to explain trends but legislative activity and advocacy campaigns by non-governmental organizations may play a role (Environmental Health Perspectives, 15 January 2014).
