Highlights•Nanoplastics were obtained from three teabag brands during a standard preparation.•ATR-FTIR shows nylon, polypropylene, and cellulose as constituents.•MNPLs release was higher for propylene and lower for nylon.•Uptake in Caco-2, HT29, and HT29-MTX human intestinal cells was determined.•Cell uptake depends on both cell type and chemical constitution of released MNPLs. AbstractThe potential health implications of environmental… Continue reading #Teabag-derived micro/#nanoplastics (true-to-life MNPLs) as a surrogate for real-life exposure scenarios

In Vivo Tissue Distribution of #Polystyrene or Mixed Polymer Microspheres and Metabolomic Analysis after Oral Exposure in Mice
Globaplastic use has consistently increased over the past century with several different types of plastics now being produced. Much of these plastics end up in oceans or landfills leading to a substantial accumulation of plastics in the environment. Plastic debris slowly degrades into microplastics (MPs) that can ultimately be inhaled or ingested by both animals… Continue reading In Vivo Tissue Distribution of #Polystyrene or Mixed Polymer Microspheres and Metabolomic Analysis after Oral Exposure in Mice
Detection of microplastics in human lung tissue using μFTIR spectroscopy
AbstractAirborne microplastics (MPs) have been sampled globally, and their concentration is known to increase in areas of high human population and activity, especially indoors. Respiratory symptoms and disease following exposure to occupational levels of MPs within industry settings have also been reported. It remains to be seen whether MPs from the environment can be inhaled,… Continue reading Detection of microplastics in human lung tissue using μFTIR spectroscopy
Sex-specific effects of bisphenol A on the signaling pathway of ESRRG in the human placenta
AbstractBisphenol A (BPA) exposure during pregnancy is associated with low fetal weight, particularly in male fetuses. The expression of estrogen-related receptor gamma (ESRRG), a receptor for BPA in the human placenta, is reduced in fetal growth restriction. This study sought to explore whether ESRRG signaling mediates BPA-induced placental dysfunction and determine whether changes in the… Continue reading Sex-specific effects of bisphenol A on the signaling pathway of ESRRG in the human placenta
Immunotoxicity and intestinal effects of nano- and microplastics: a review of the literature
BackgroundTogether with poor biodegradability and insufficient recycling, the massive production and use of plastics have led to widespread environmental contamination by nano- and microplastics. These particles accumulate across ecosystems - even in the most remote habitats - and are transferred through food chains, leading to inevitable human ingestion, that adds to the highest one due… Continue reading Immunotoxicity and intestinal effects of nano- and microplastics: a review of the literature
Non-target screening for the identification of migrating compounds from reusable plastic bottles into drinking water
Highlights•Migration of > 400 plastic related and > 3500 dishwasher related compounds. •The dishwashing process increased the migration of plastic related compounds. •Oligomers suspected from polycaprolactone (PCL) were migrating. •Three of the identified photoinitiators have possible endocrine disrupting effects. •Diethyltoluamide (DEET) may have been formed from the plasticizer laurolactam. AbstractReusable plastic sports bottles are used… Continue reading Non-target screening for the identification of migrating compounds from reusable plastic bottles into drinking water
Adipogenic Activity of Chemicals Used in Plastic Consumer Products
Bisphenols and phthalates, chemicals frequently used in plastic products, promote obesity in cell and animal models. However, these well-known metabolism-disrupting chemicals (MDCs) represent only a minute fraction of all compounds found in plastics. To gain a comprehensive understanding of plastics as a source of exposure to MDCs, we characterized the chemicals present in 34 everyday… Continue reading Adipogenic Activity of Chemicals Used in Plastic Consumer Products
#Plastics, #EDCs & Health: Authoritative Guide
The Endocrine Society and IPEN (International Pollutants Elimination Network) are proud to present this authoritative and comprehensive report to addresses how plastics can harm human health. An expert overview of twenty years of research shows that plastics pose a threat to public health because they contain a host of hazardous, endocrine-disrupting chemicals (EDCs) that leach… Continue reading #Plastics, #EDCs & Health: Authoritative Guide
Air #pollution as a determinant of food delivery and related #plastic waste
Plastic waste is a growing environmental concern. The food delivery industry is criticized for its environmental impact, especially its current use of plastic packaging. At the same time, the environment impacts the industry. We show that air pollution is a behavioural driver of food delivery consumption in the urban developing world. Our hypothesis is that… Continue reading Air #pollution as a determinant of food delivery and related #plastic waste
