Abstract:
... Microplastics (<5 mm) are a threat to marine biodiversity however their effects on animal cognition and behaviour are unclear. We investigated whether microplastic exposure affects shell selection behaviour and motivation in the common European hermit crab, Pagurus bernhardus. Subjects were maintained for 5 days in tanks containing either: polyethylene microplastic spheres (n = 40), or no plastic ...

Abstract:
... Although biodegradable plastics are considered an environmentally-friendly alternative to conventional plastics, the effects of biodegradable microplastics (BMPs) on soil faunal communities are poorly understood, especially under field conditions. Here, we investigated the loading impacts of two conventional low-density polyethylene (LDPE) and polypropylene (PP) MPs as well as two biodegradable po ...

Abstract:
... Pyrolysis is considered an attractive option and a promising way to dispose waste plastics. The thermogravimetric experiments of high-density polyethylene (HDPE) were conducted from 105 °C to 900 °C at different heating rates (10 °C/min, 20 °C/min, and 30 °C/min) to investigate their thermal pyrolysis behavior. We investigated four methods including three model-free methods and one model-fitting m ...

Abstract:
... Bisphenol A (BPA), a synthetic chemical which has raised concerns due to its potential toxicological effects on humans, has been widely detected in canned and non-canned meat and meat products. This study estimated BPA migration from packaging to non-canned and canned meat products by developing two probabilistic models. BPA concentration data in packaging materials were collated, including polyet ...

Advanced solid phase extraction (SPE) fibrous sorbents including polyethylene, polypropylene poly (hydroxybutyrate), and polyamide 6 nanofibers, polycaprolactone microfibers/nanofibers, polycaprolactone microfibers/polyvinylidene difluoride nanofibers, and poly (hydroxybutyrate) microfibers/polypropylene microfibers composites, as well as commercial molecularly imprinted polymers and restricted ac ...
... There is an urgent need for data on microplastics (MPs) in uptake media relevant to humans. Here we apply Laser Direct Infra-Red (LDIR) spectroscopy for the rapid analysis of MP> 10 µm in clean matrices such as bottled drinking water and (deposited) air samples, using strict QA/QC criteria. Nine water bottles of three different brands were found to contain on average 96 particles/L (range 7–364, m ...

Abstract:
... The optical properties and humidity response of iridescent films made of cellulose nanocrystal (CNC) and polyethylene glycol (PEG) can be tailored by the incorporation of electrolytes chosen based on specific ion effects (SIE). A series of inorganic salts comprising five different cations and five anions based on the Hofmeister series were mixed with CNC/PEG suspensions, followed by an air-dried p ...

Abstract:
... Novel phase change materials composed of polyethylene glycol (PEG), cellulose nanofibers (CNFs) and carbon nanotubes (CNTs) were developed by an efficient and environment friendly strategy. The CNFs were modified and cross-linked by chitosan to form three-dimensional network structure, which provides strong support for the resulting CNF/CNT/PEG composites. The structure and properties of CNF/CNT/P ...

Abstract:
... Studies in recent years have shown that aquatic pollution by microplastics (MPs) can be considered to pose additional stress to amphibian populations. However, our knowledge of how MPs affect amphibians is very rudimentary, and even more limited is our understanding of their effects in combination with other emerging pollutants. Thus, we aimed to evaluate the possible toxicity of polyethylene MPs ...

Abstract:
... Microplastics (MPs) are frequently detected in urban waters, which would pose a threat to human health through the food chain. Thus, efficient approaches to the elimination of MPs are urgently required. Pyrolysis is a powerful technique for the potential treatment of MPs. The online thermogravimetry-Fourier transform infrared reflection-Mass spectrometry (TG-FTIR-MS) is applied for tracking the py ...
... The hypoxic tumor microenvironment and photodynamic therapy (PDT)-aggravated hypoxia compromise the anticancer efficacy of chemotherapy, immunotherapy, and PDT. Thus, sophisticated nanomedicines that can activate their anticancer capability in situ in response to specific stimuli need to be developed. This study aimed to construct a hybrid nanomedicine that activated chemotherapy by inducing hypox ...
... Microplastic pollution in terrestrial ecosystems is a growing concern due to its potential influences on soil properties and crop growth. Little is known about the effects of microplastics on the microbiome in the rhizosphere. Here, we studied the effects of two types of microplastics (MPs), low density polyethylene (LDPE-MPs) and biodegradable microplastic (Bio-MPs) of poly-butylene-adipate-co-te ...

Abstract:
... Cattle ranching has increased globally in the last decades, and although pasture expansion is well documented across different regions, there is little understanding of the intensity at which cattle operate in these areas. With freely available Sentinel-2 satellite imagery, we mapped for the first time polyethylene silage bags used for forage conservation in a year with the Random Forest algorithm ...
... In the current research, titanium dioxide (TiO₂) and zinc oxide (ZnO) nanoparticles using ethylene ethyl acrylate as compatibilizer are incorporated into low-density polyethylene (LDPE) to generate active nanocomposite films (ANFs) using melt blowing technique. The film properties such as colour, thickness, mechanical and thermal properties, surface morphology, and molecular composition were analy ...

This article proposes a framework for ex-ante life cycle assessment (LCA) of biopolymers at low TRL, including: (i) scale-up; (ii) scenarios for processes and modelling choices; (iii) comparison with a fossil-based polymer, considering material substitution factors. The framework was applied to analyse a mango kernel starch (MKS) film and compare it with low-density polyethylene (LDPE). Mango seed ...
... Plastic is exceedingly abundant in soils, but little is known about its ecological consequences for soil microbiome functioning. Here we report the impacts of polyethylene and biodegradable Ecovio and BI-OPL plastic films buried in alpine soils for 5 months on the genetic potential of the soil microbiome using shotgun metagenomics. The microbiome was more affected by Ecovio and BI-OPL than by poly ...
... Plastics are versatile and pervasive materials, useful in countless applications and industries. Nevertheless, their high disposal and environmental stability are raising concerns and microplastics are now considered emerging food contaminants by moving all the way up the food chain. High level of uncertainty remains regarding the risks derived from human dietary exposure to microplastics. The aim ...

Abstract:
... As an ecological niche close to the polymer, microorganisms in the plastisphere possess the advantage of degrading plastics. This study aims to investigate the bacterial community succession and obtain degrading bacteria in the plastisphere, as well as identify the most efficient degradation combination by co-culture of multiple strains. The findings demonstrate the alpha-diversity indices of the ...
... Mother of FT and TFL1 (MFT) is a member of the phosphatidylethanolamine-binding protein (PEBP) family, which plays important roles in seed development, the stress response, and flowering time regulation. In the present study, the MFT homologous gene MiMFT was identified in mango cultivar ‘SiJiMi’. The promoter of MiMFT contained phytohormone-, plant growth-, plant development-, and abiotic stress- ...
... Microplastics (MPs) can affect soil organic carbon (C) cycling in paddy soil by changing microbial function and soil properties. In this study, a laboratory incubation experiment was applied to explore the effect of polyethylene (PE) MP on methane (CH₄) and carbon dioxide (CO₂) emissions from paddy soils after rice straw addition. Moreover, the microbial functional genes encoding CH₄ oxidation and ...
