Humans are chronically exposed to airborne microplastics (MPs) by inhalation. Various types of polymer particles have been detected in lung samples, which could pose a threat human health. Inhalation toxicological studies crucial for assessing the effects MPs and exposure-reduction measures. This communication paper addresses important health concerns related MPs, taking into consideration three levels complexity, i.e., themselves, additives present plastics, exogenous substances adsorbed...
Tire and road wear particles (TRWP) account for an important part of the polymer released into environment. There are scientific knowledge gaps as to potential bioaccessibility chemicals associated with TRWP aquatic organisms. This study investigated solubilization seven most widely used tire-associated organic four their degradation products from cryogenically milled tire tread (CMTT) fish digestive fluids using in vitro digestion model based on Oncorhynchus mykiss. Our results showed that...
Abstract Water contamination due to environmental conditions and poor waste management in certain areas of the world represents a serious problem accessing clean safe drinking water. This is especially critical electricity-poor regions, where advanced water purification methods are absent. Here, we demonstrate that titanium dioxide nanowires (TiO 2 NWs)-based photocatalytic filters assisted only with sunlight can efficiently decontaminate Moreover, interweaving TiO NWs carbon nanotubes...
N-nitrosamines are formed during different industrial processes and of significant concern due to their carcinogenic mutagenic properties. This study reports concentrations in eight wastewater treatment plants Switzerland the variability abundance. Only four species, N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA), N-nitrosodibutylamine (NDPA) N-nitrosomorpholine (NMOR) were above limit quantification this campaign. Remarkably high (i.e. up 975 μg NDMA/L, 90.7 NDEA/L, 1.6 NDPA/L...
Chloroform has been for a long time considered only as an anthropogenic contaminant. The presence of chloroform in forest soil and groundwater widely demonstrated. frequent detection absence other contaminants suggests that is likely produced naturally. Compound-specific isotope analysis was performed on soil-gas samples to elucidate whether its source natural or anthropogenic. δ13C values (−22.8 −26.2‰) present gas collected forested area are within the same range organic matter (−22.6...
The contamination of water resource and food chain by persistent organic pollutants (POPs) constitutes a major environmental human health concern worldwide. aim this study was to investigate the levels POPs in irrigation water, soil Amaranthus viridis (A. viridis) from different gardening sites Kinshasa evaluate potential risks. A survey for use pesticides fertilizers carried out with 740 market gardeners. (including organochlorine (OCPs), polychlorinated biphenyls (PCBs), polybrominated...
The sorption of hydrophobic organic compounds (HOC) onto microplastics is relatively well reported in the literature, while their desorption remains poorly investigated, especially biological fluids. present study investigated and progesterone on polyethylene (PE), polypropylene (PP), polystyrene (PS) microplastics. experiments showed that equilibrium was reached a few hours for all plastics. A efficiency 357.1 μg g-1 found PE PS, 322.6 PP. Sorption indicated adsorption would certainly...
Microplastics, especially aged microplastics can become vectors of metals from environment to organisms with potential negative effects on food chain. However, a few studies focused the bioavailability adsorbed and most related used artificial method that cannot entirely reflect actual aging processes. In this study, virgin polystyrene was by ozone (PS-O3), solar simulator (PS-SS) lake (PS-lake) investigate adsorption Cu virgin, artificially naturally subsequent release in simulated...
Tire and road wear particles (TRWP) have been shown to represent a large part of anthropogenic released into the environment. Nevertheless, potential ecological risk TRWP in different environmental compartments their toxic impacts on terrestrial aquatic organisms remain largely underinvestigated. Several heavy metals compose TRWP, including Zn, which is used as catalyst during vulcanization process rubber. This study investigated solubilization from cryogenically milled tire tread (CMTT)...
Oxidative stress can contribute to the development of diseases, and may originate from exposures toxicants commonly found in air pollution cigarette smoke such as polycyclic aromatic hydrocarbons (PAHs) volatile organic compounds (VOCs). Yet, associations between these oxidative biomarkers are poorly characterized. We report here novel 14 exposure PAHs VOCs, two biomarkers; 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) 8-isoprostaglandin F2α (8-isoprostane) urine obtained smokers...
There is growing concern about rubber-derived compounds (RDCs), predominantly originating from tire and road wear particles. Other consumer products, including sports equipment, also contain RDCs human exposure to these of particular interest due demonstrated toxicity animal species. In this study, we investigated intentionally incorporated into climbing shoes for enhanced performance. We found high concentrations 15 rubber derived-compounds (RDCs) in shoe sole samples (Σ15 RDCs: 25 – 3405...
N-Nitrosamines are potent mutagens and carcinogens that can be formed during oxidative water treatment. This study describes a novel method for the determination of total N-nitrosamines by UV-photolysis subsequent chemiluminescence detection nitric oxide. Denitrosation was accomplished with microphotochemical reactor consisting knitted reaction coil low-pressure mercury lamp. The limits differing ranged between 0.07 μM (14 pmol injected) 0.13 (26 injected). oxide formation from selected...
Tire and road wear particles (TRWP) resulting from tire abrasion while driving raise concerns due to their potential contribution aquatic toxicity. Our study aimed assess cryogenically milled tread (CMTT) particle toxicity, used as a proxy for TRWP, associated chemicals fish using two Rainbow Trout (Oncorhynchus mykiss) cell lines representing the gill (RTgill-W1) intestinal (RTgutGC) epithelium. CMTT toxicity was evaluated through several exposure pathways, including direct contact,...
N-Nitrosamines are potential human carcinogens frequently detected in natural and engineered aquatic systems. This study sheds light on the role of carbonyl compounds formation N-nitrosamines by nitrosation five secondary amines via different pathways. The results showed that compared to a control system, presence formaldehyde enhances factor 5–152 at pH 7, depending structure amines. Acetaldehyde slight enhancement effect N-nitrosamine formation, while acetone benzaldehyde did not promote...
