New study examines long-term effects of polystyrene (PS) nanoplastics on mitochondrial health under realistic exposure conditions; repeated exposure to PS nanoplastics impaired mitochondrial function and cell differentiation process, possibly linked to metabolic disorders, such as diabetes and obesity; other recent studies found that PS micro- and nanoplastics negatively affect immune function, pregnancy outcomes, and gut health in various models
Many questions surround microplastics, what about micro(bio)plastics?
Literature review of micro- and nano(bio)plastics research; scrutinizes the complexities of micro- and nano(bio)plastics degradation and their toxicological effects; highlights gaps in long-term impact studies and interactions with environmental conditions; challenges the assumption that “biodegradable” means complete degradation; calls for greater transparency in research practices to bolster collective understanding
Deciphering the differences in plastic particles reported in foods
Two studies investigate micro- and nanoplastics measured in foods; review the range of reported values and diversity of study methods; make suggestions to standardize research methodologies; one study outlines additional standards the micro – nanoplastics research community needs to develop in order to assist regulators
Report outlines how plastic production harms human health, environment, economy
Minderoo-Monaco Commission on Plastics and Human Health publishes extensive report summarizing plastics’ effects across life cycle on human health, environment, and the economy; health effects cost society hundreds of billions every year; report includes actions for “governments and industries to minimize the negative consequences of global plastic contamination”
State of the science and regulation – microplastics and nanoplastics
California State Policy Evidence Consortium and DG Environment publish reports on the abundance, health effects and (potential) regulations on microplastics and nanoplastics, respectively; first finds most regulations come from California or EU and concern banning microbeads or mandating more research; second argues against a lower size cutoff of nanoplastics since the smaller the plastic particles, the more likely they can cross biological membranes
Microplastics detected in human breastmilk and mice fetal thalamus
Two studies assess fetal and infant exposure to plastic particles and impacts on mouse fetuses; detect microplastics in 26 out of 34 human breastmilk samples; report polystyrene particles negatively impact mouse fetuses
Microplastic effects on colon cells, blood lymphocytes, and gut-liver axis
Two in vitro studies analyze plastic particle effects using human cells; find polystyrene (PS) particles change metabolism of human colon cells similar to a carcinogen; PS nanoplastics may have cytotoxic and genotoxic potential on human blood lymphocytes; mouse study indicates microplastics increase risk of insulin resistance; researchers calculate particle ingestion from takeaway containers
2021 FPF Workshop: Sharing recent scientific research
On the first day of the Food Packaging Forum’s annual workshop, speakers discuss their latest scientific research projects covering food contact chemical migration, human biomonitoring, mixture effects, threshold levels, microplastics, and impacts on reproduction
Reviews on effects of micro- and nanoplastics in vitro and in vivo
Literature reviews summarize in vitro and in vivo studies on micro- and nanoplastics; report on various exposure and adsorption pathways and toxic effects of plastic particles; human health impacts to be evaluated under realistic exposure scenarios
New Horizon 2020 projects to research impacts of micro- and nanoplastics
CUSP cluster launches with five research projects supported by €30 million in EU funding; aims to investigate complex relationships between micro- and nanoplastics and human health over the next five years; Food Packaging Forum collaborates within the AURORA project focused on early-life health
