There is a growing concern within the medical community about potential burden of microplastics on human organs and tissues. In this study, we investigated by microRaman spectroscopy presence in kidneys urine. Moreover, an open-access software was developed validated for project, which enabled comparison between spectra self-created spectral database, thus enhancing ability to characterize polymers pigments biological matrices. Healthy portions ten obtained from nephrectomies, as well urine...
The World Health Organization has confirmed that asbestos fibres are carcinogenic, claiming asbestos-related diseases should be eradicated worldwide. Actinolite, amosite, anthophyllite, chrysotile, crocidolite, and tremolite regulated asbestiform mineral phases. However, in nature, minerals occur either a fibrous (original morphology characterized by high length-to-width ratio provided of tensile strength flexibility) or but not appearance. This study used human epithelial cancer cells...
Abstract Alginate is a naturally occurring polysaccharide commonly derived from brown algae cell walls which possesses unique features that make it extremely promising for several biomedical and pharmaceutical purposes. biomaterials are indeed nowadays gaining increasing interest in drug delivery tissue engineering applications owing to their intrinsic biocompatibility, non‐toxicity, versatility, low cost, ease of functionalization. Specifically, alginate‐based nanostructures show enhanced...
Abstract Plastics are synthetic organic compounds whose widespread use generates enormous waste. Different processes, such as mechanical abrasion, microbiological activity, and UVB irradiation, can fragment the plastic material generate microplastics (MPs). MPs ubiquitous, various organisms, including humans, ingest or inhale them, with potential adverse health effects. The differences between UV-aged virgin particles were studied to evaluate genotoxic damage oxidative stress induced by...
Nicotine is an important emerging contaminant widely detected in water resources. The main nicotine sources are human excretions from users and leaching discarded tobacco product waste, which represents the most commonly littered item urban areas coasts. In this study, UV254 photolytical fate of natural leachates produced conventional cigarettes (CCs) new generation heat-not-burn (HnBs) products examined for first time. effect irradiation on depletion ultrapure was initially studied....
In this contribution, the photoactivity upon activation by simulated sunlight of zinc oxide (ZnO) obtained from two different synthetic pathways (Acetate and Nitrate) is investigated for water purification. Different reagents processes were exploited to obtain ZnO nanoparticles. Products have been characterized means X-Ray Diffraction, Scanning Electron Microscopy along with Energy Dispersive Spectrometer, Dynamic Light Scattering, Diffuse Reflectance Measurements, highlight outcomes...
Abstract Background and Aims Microplastics (MPs), plastic fragments less than 5mm in diameter, have been recognized as a global environmental issue. Various studies shown their ubiquitous presence toxicity on marine terrestrial fauna. Currently humans, the of MP has evidenced lungs, placenta, blood, liver. However, there is still very little knowledge about different organs tissues prospective toxicity. The objective this study was to investigate microplastics human kidneys urine. Method We...
Microplastics (MPs) in drinking water (DW) raise concerns about their potential impacts on health. Several substances, such as plasticizers and stabilizers, can be leached from plastic polymers following abiotic biotic denaturation processes. Furthermore, the purification treatment of DW, chlorination process, significantly increases release chemical components that are part polymer composition. Recently, several studies reported MPs adsorb environmental xenobiotics, organic molecules heavy...
Abstract Microplastic particles (MPs) are ubiquitous environmental pollutants that can remain in ecosystems for prolonged periods. Plastic materials undergo various degradation processes driven by chemical, physical, and biological factors alter their size, shape, composition, bioavailability. The gastrointestinal tract is the primary pathway through which MPs absorbed, raising concerns as they transport harmful microorganisms into body. Despite widespread presence, effects of exposure to...
An innovative photocatalyst was prepared via sol-gel process by combining TiO2 with commercial CaAl2O4 persistent luminescence material (PeL), to act as internal irradiation source. To find the optimized synthetic conditions for enhanced photocatalytic efficiency, a full factorial experimental design (23) applied, investigating degradation of Methylene Blue (MB). Significant samples were characterized XRD, DRS, SEM-EDS, and BET techniques then tested Salbutamol Contaminant Emerging Concern...
