HEEDS tracks and summarizes new science on endocrine disrupting chemicals (EDCs) every day. Twice a week we summarize the most important and interesting new studies, in partnership with Environmental Health News, listed below.
For a comprehensive list of all new studies, see our EDC Science Weekly. For a weekly summary of new studies on EDCs in relation to diabetes and obesity, see our Research Roundup on Metabolism Disruptors.

ECHO study finds exposure to air pollution during early pregnancy associated with lower birthweight
by EHN Curators on February 17, 2026 at 2:49 pmExposure to fine particulate matter—very small inhalable particles found in air pollution—during early pregnancy was associated with babies being slightly smaller at birth.
-
Nanoplastics sneak into brain cells, disrupting fertility hormones
by EHN Curators on February 16, 2026 at 11:58 amTiny plastic particles reduced hormone levels, slowed cell movement, and altered genes required for reproductive health in brain cells, a new study shows.

Microplastics may leach from hot to-go coffee cups, study finds
by EHN Curators on February 11, 2026 at 5:48 pmWith daily coffee drinking at record highs, to-go cups are just part of the morning routine. However, that everyday convenience comes with a caveat, as new research suggests that those cups can release microplastics into hot drinks, especially as temperatures rise.
-
Pacifiers can be a source of BPA exposure, even when marketed as “BPA-free”
by Environmental Health Sciences Staff on February 6, 2026 at 6:34 pmA recent study published in Environmental Science and Pollution Research found that plastic pacifiers could expose children to bisphenol A (BPA), a toxic chemical known to harm reproductive, developmental, neurological, and metabolic health.
