Scientists explore effects of micro- and nanoplastics on mammals, including humans

Research studies show maternal polystyrene (PS) particle exposure can cause testicular and hepatic toxicity in male mouse offspring; report PS microplastics affect rat ovary function; find correlation between human fecal microplastics levels and Inflammatory Bowel Disease; reviews summarize potential human health effects; study develops a tool to screen and prioritize micro-and nanoplastics toxicity studies for human health risks evaluation

Several studies determine chemical migration from food packaging

Researchers from several European and Chinese institutions develop methods to explore chemicals in food contact materials (FCMs); report styrene migration from different polystyrene FCMs into several food matrices; detect photoinitiators in paper FCMs and chlorinated paraffins in green tea and its packaging; find irradiation treatment of metalized polypropylene to reduce migration of tested chemicals

EFSA proposes to lower daily tolerable intake of bisphenol A

European Food Safety Authority (EFSA) re-evaluation proposes to significantly lower the tolerable daily intake of bisphenol A (BPA) from 4 to 0.00004 micrograms per kilogram of bodyweight per day due to immune system effects; finds many consumers likely exposed beyond the new safe limit; feedback accepted on the draft opinion until February 22, 2022

Study finds sex-specific impacts of prenatal phthalate exposure

Taiwanese cohort study examines prenatal phthalate exposure effects on infant birth weight and gestational age; reports higher impact on male neonates

Studies discuss EDC sources, exposure, and human health effects

Scientific studies investigate human endocrine-disrupting chemical (EDC) exposures and effects; Canadian study finds bisphenols migrate from baby bottles and sippy cups; reviews report of widespread presence of bisphenols, parabens, and benzophenones in human breast milk and addresses current misunderstandings about the impacts of EDCs on child health

Why do “chemicals” need simplifying?

Scientists’ Viewpoint proposes ‘chemical simplification’ to deal with increasing chemical pollution; names reduction of number of chemicals used in products and grouping approaches as cornerstones for simplification and innovation in science and engineering as prerequisite

Phthalate exposure and health impacts

Four scientific articles report on phthalate exposure sources and impacts; diet partly explains urinary phthalate levels in adolescents and children surveyed in the US and New Zealand; review of reviews summarizes human health impacts; finds studies on women “generally underrepresented”; study indicates three phthalates affect human oral health

Microplastics may affect the human microbiome

Scientists explore potential impacts of microplastics on human intestine ecology; microplastics may drive unhealthy changes in the gut microbiome; authors highlight importance of assessing human microplastics exposure and hazards for the gut

Microplastics measured in newborn, infant, and adult feces

Small study assesses polyethylene terephthalate (PET) and polycarbonate (PC) microplastics in human feces; finds PET and PC in all infant stool and in most meconium and adult stool samples; suggests higher exposure of infants than adults

Bisphenols in thermal paper extracts and drinking bottle migrates

Scientific studies analyze bisphenol content in thermal papers and migrates from reusable drinking bottles; of 14 analyzed bisphenols 4 detected in thermal receipts and 3 in bottles migrates at low concentrations; dishwashing but not handwashing prior to use reduces bisphenol A (BPA) leaching from Tritan
