ACC supports EPA report on non-monotonic dose-response and low dose effects
New infographics on EDCs
Health and Environment Alliance releases infographics on endocrine disrupting chemicals, focuses on the need to accommodate low dose effects and science advances into risk assessment
BPA shown to disrupt sperm development
U.S. researchers show that brief exposures to BPA and other estrogens early in life can alter the stem cells involved in sperm production years later
Chemicals in plastics and obesity
U.S. researchers discuss contribution of exposure to endocrine disruptors to metabolic disorders such as obesity and diabetes
ECHA’s CLH proposal on TBBPA open for consultation
Norway submits harmonized classification and labeling (CLH) proposal to European Chemical Agency (ECHA) for brominated flame retardant tetrabrombishpenol A (TBBPA); suggests adding classification of being possibly carcinogenic following rodent studies providing evidence; proposal still open for comments until January 29, 2021
Sludge as observatory for chemical exposure
New study proposes to assess sludge as a proxy for human exposure; improving chemical risk assessment of chemicals of emerging concern
What happens to micro- and nanoplastics in the body?
Study proposes a preliminary physiologically-based toxicokinetic (PBTK) model for micro- and nanoplastics (MNPs); polymer type, size, shape, surface chemistry, surface biofilms, and biocorona determine toxicokinetic rates; models for engineered nanoparticles are not appropriate due to heterogeneity of MNPs; uptake via inhalation and effects of absorbed chemicals need more investigation
