Exposure to micro- and nanoplastic particles (MNPs) in humans is being identified both the indoor outdoor environment. Detection of these materials air has made inhalation exposure MNPs a major cause for concern. One type plastic polymer found settings polyamide, often referred as nylon. Inhalation combustion-derived, metallic, carbonaceous aerosols generate pulmonary inflammation, cardiovascular dysfunction, systemic inflammation. Additionally, due additives present plastics, may act...
Despite mounting evidence of micro-nanoplastics (MNPs) in food and drinking water, little is known the potential health risks ingested MNPs, nothing their impact on nutrient digestion absorption. We assessed effects environmentally relevant secondary MNPs generated by incineration polyethylene (PE-I), absorption fat a high model using 3-phase
Laser printers emit high levels of nanoparticles (PM0.1) during operation. Although it is well established that toners contain multiple engineered nanomaterials (ENMs), little known about inhalation exposures to these and work practices in printing centers. In this report, we present a comprehensive exposure assessment indoor microenvironments at six commercial centers Singapore, the first such outside United States, using real-time personal stationary monitors, time-integrated...
Abstract Herein, a Safe‐and‐Sustainable‐by‐Design (SSbD) screening strategy on four different inorganic aerogel mats and two conventional mineral wools for ranking purposes is demonstrated. Given that they do not consist of particles, the release first simulated, addressing three occupational exposure scenarios, realistic their intended use as building insulators. No to consumers nor environment foreseen in phase, however, aerosols may be released during mat installation, posing an...
Nano-enabled products (NEPs) represent a growing economic global market that integrates nanotechnology into our everyday lives. Increased consumer use and disposal of NEPs at their end life has led to increased environmental, health safety (EHS) concerns, due the potential environmental release constituent engineered nanomaterials (ENMs) used in production NEPs. Although, there is an urgent need assess particulate matter (PM) scenarios EHS implications, no current standardized methodologies...
The proliferation of nano-enabled products (NEPs) renders human exposure to engineered nanomaterials (ENMs) inevitable. Over the last decade, risk assessment paradigm for focused primarily on potential adverse effect pristine, as-prepared ENMs. However, physicochemical properties ENMs may be drastically altered across their life-cycle (LC), especially when they are embedded in various NEP matrices. Of a particular interest is end-of-life scenario by thermal decomposition. main objective...
The study investigates the effect of synthesis parameters nano-enabled products on potential release engineered nanomaterials during thermal decomposition.
The COVID-19 pandemic has created an urgent need to utilize existing and develop new intervention technologies for SARS-CoV-2 inactivation on surfaces in the air. Ultraviolet (UV) technology been shown be effective antimicrobial intervention. Here a study was conducted determine efficacy of commercially available UV blue light-based devices inactivating HCoV-229E, surrogate SARS-CoV-2. results indicate that two designed surface disinfection, with doses 8.07 µJ/cm2 254 nm device 20.61 275...
Nano-enabled products are ultimately destined to reach end-of-life with an important fraction undergoing thermal degradation through waste incineration or accidental fires. Although previous studies have investigated the physicochemical properties of released lifecycle particulate matter (called LCPM) from decomposition nano-enabled thermoplastics, critical questions about effect nanofiller on chemical composition LCPM still persist. Here, we investigate potential effects profiles 16...
Metal oxide nanoparticles (NPs) are increasingly used in many industrial and biomedical applications, hence their impact on occupational public health has become a concern. In recent years, interest the effect that exposure to NPs may exert human reproduction grown, however data still scant. present work, we investigated whether different metal interfere with mouse cumulus cell-oocyte complex (COC) expansion. Mouse COCs from pre-ovulatory follicles were cultured vitro presence of various...
Several engineered nanomaterials (ENMs) are used in toner-based printing equipment (TPE) including laser printers and photocopiers to improve toner performance. High concentration of airborne nanoparticles due TPE emissions has been documented copy centers chamber studies. Recent animal inhalation studies by our group suggested exposure printer-emitted (PEPs) increased cardiovascular risk impairing ventricular performance inducing hypertension arrhythmia, consistent with global...
Wood burning contributes to indoor and ambient particulate matter (PM) pollution has been associated with increased morbidity mortality. Here, we present an integrated methodology that allows generate, sample, characterize wood smoke derived from different moisture contents representative combustion conditions using pine as a model. Flaming, smoldering, incomplete were assessed for low-moisture pine, whereas both high-moisture investigated under flaming conditions. Real-time monitoring of...
Abstract Background Engineered nanomaterials are increasingly being incorporated into synthetic materials as fillers and additives. The potential pathological effects of end-of-lifecycle recycling disposal virgin nano-enabled composites have not been adequately addressed, particularly following incineration. current investigation aims to characterize the cytotoxicity incinerated thermoplastics vs. thermoplastic on two in vitro pulmonary models. Ultrafine particles released from thermally...
