Interactions of environmentally relevant polyethylene terephthalate (PET) micro-nanoplastics with toxic elements and organic co-pollutants: Chemical corona formation and impact on toxicity and bioavailability during gastrointestinal co-ingestion

Satwik Majumder, Glen M. DeLoid, Mandeep Kaur, Eshun Gaddi et autres

The ability of environmental pollutants (EPs) to interact with and form chemical coronas on micro-nanoplastics (MNPs) raises significant concerns about potential toxicological effects in biological systems. Here, we investigated the formation of chemical coronas of toxic elements (Arsenic-As, Lead-Pb, and Chromium-Cr) and …

Wildland-Urban Interface Fires: Toxic Physicochemical Properties of Emitted Particulate Matter and Impacts on Lung Macrophages

Glen M. DeLoid, Lila Bazina, Leonardo D. Calderón, Georgios A. Kelesidis et autres

High Resolution Image Download MS PowerPoint Slide Due to the growth of urban areas in close proximity to wildlands, wildfires increasingly burn both biomass and man-made materials. The physicochemical properties of emitted particulate matter (PM) from such “wildland-urban interface (WUI)” fires may …

Impact of nanoplastics emitted from incineration of polyethylene plastic on THP-1 macrophage viability and immune function

Lila Bazina, Glen M. DeLoid, Leonardo D. Calderón, Luke Fritzky et autres

Inhalation exposure to micro-nanoplastics (MNPs) generated by plastic waste incineration is an emerging public health concern. This study assessed the impact of nanoparticles emitted during the incineration of high-density polyethylene (HDPE-I) on THP-1 lung macrophages. HDPE-I nanoparticles (<0.1 µm) were generated using …

Impact of UV Aging on the Toxicity and Bioavailability of Inductively Coupled Plasma Mass Spectrometry (ICP-MS)-Traceable Core–Shell Polystyrene Nanoplastics in an In Vitro Triculture Small Intestinal Epithelium Model

Satwik Majumder, Lila Bazina, Glen M. DeLoid, Alvaro Garcia et autres

A major bottleneck in evaluating the environmental health implications of micro-nanoplastics (MNPs) is the inadequacy of analytical techniques for their precise quantification within complex environmental and biological matrices. Additionally, there is a conspicuous paucity of studies addressing environmentally relevant, photo-aged MNPs. In …

Development and characterization of reference environmentally relevant micro-nano-plastics for risk assessment studies

Milton Das, Leonardo D. Calderón, Dilpreet Singh, Satwik Majumder et autres

Micro- and nano-plastics (MNPs) have become ubiquitous environmental pollutants. Extensive toxicological studies of MNPs have been conducted in recent years. However, because of the difficulties involved in extraction and collection of MNPs from environmental media, most of these studies have employed simplistic, …

Toxicity and absorption of polystyrene micro-nanoplastics in healthy and Crohn’s disease human duodenum-chip models

Davood Kharaghani, Glen M. DeLoid, Ping He, Ben Swenor et autres

Micro and nanoplastics (MNPs) are widespread environmental and food web contaminants that are absorbed by the intestine and distributed systemically, but the mechanisms of uptake are not well understood. In a triculture small intestinal epithelial model, we previously found that uptake of …

Impact of Canadian Wildfire-Emitted Particulate Matter on THP-1 Lung Macrophage Health and Function

Lila Bazina, Glen M. DeLoid, Luke Fritzky, Denisa Lizoňová et autres

Increasing frequency and intensity of climate-driven wildfires in recent years have resulted in increased human exposures to wildfire smoke and raised serious public health concerns. One potential risk of wildfire smoke exposure is the impairment that it may cause to lung macrophages, …

Ingested Polystyrene Micro-Nanoplastics Increase the Absorption of Co-Ingested Arsenic and Boscalid in an In Vitro Triculture Small Intestinal Epithelium Model

Davood Kharaghani, Glen M. DeLoid, Trung Huu Bui, Nubia Zuverza‐Mena et autres

Micro-nano plastics (MNPs) are emerging environmental and food contaminants that are raising serious health concerns. Due to the polycontamination of the food web with environmental pollutants (EPs), and now MNPs, the co-ingestion of EPs and MNPs is likely to occur, and the …
