Engineered nanomaterials (ENM) are already used in many products and consequently released into environmental compartments. In this study, we calculated predicted concentrations (PEC) based on a probabilistic material flow analysis from life-cycle perspective of ENM-containing products. We modeled nano-TiO2, nano-ZnO, nano-Ag, carbon nanotubes (CNT), fullerenes for the U.S., Europe Switzerland. The were as density functions compared to data ecotoxicological studies. simulated modes (most...
The aim of this study was to use a life-cycle perspective model the quantities engineered nanoparticles released into environment. Three types were studied: nano silver (nano-Ag), TiO2 (nano-TiO2), and carbon nanotubes (CNT). quantification based on substance flow analysis from products air, soil, water in Switzerland. following parameters used as inputs: estimated worldwide production volume, allocation volume product categories, particle release products, coefficients within environmental...
Nanosilver is one nanomaterial that currently under a lot of scrutiny. Much the discussion based on assumption nanosilver something new has not been seen until recently and advances in nanotechnology opened completely application areas for silver. However, we show this analysis form colloidal silver used more than 100 years registered as biocidal material United States since 1954. Fifty-three percent EPA-registered products likely contain nanosilver. Most these applications are...
Microplastic fibers make up a large proportion of microplastics found in the environment, especially urban areas. There is good reason to consider synthetic textiles major source microplastic fibers, and it will not diminish since use fabrics, polyester, continues increase. In this study we provide quantitative data regarding size mass released from (polyester) during simulated home washing under controlled laboratory conditions. Consideration fabric structure conditions (use detergents,...
The widespread use of silver nanoparticles (Ag-NPs) in commercial products, especially textiles, will likely result an unknown spread Ag into the environment. quantification and characterization released from nano-Ag-products is important parameter needed to predict effect Ag-NPs on aim this study was determine amount form during washing nine fabrics with different ways incorporation or onto fibers. pH, surfactants, oxidizing agents evaluated. results show that little dissolution occurs...
Metal pollution of soils is widespread across the globe, and clean up these a difficult task. One possible remediation technique ex-situ soil washing using chelating agents. Ethylenediaminetetraacetic acid (EDTA) very effective agent for this purpose but has disadvantage that it quite persistent in environment due to its low biodegradability. The aim our work was investigate biodegradable agents [S,S]-ethylenediaminedisuccinic (EDDS), iminodisuccinic (IDSA), methylglycine diacetic (MGDA),...
The need for an environmental risk assessment engineered nanomaterials (ENM) necessitates the knowledge about their concentrations. Despite significant advances in analytical methods, it is still not possible to measure concentrations of ENM natural systems. Material flow and fate models have been used provide predicted However, almost all current are static consider neither rapid development production nor fact that many entering in-use stock released with a lag phase. Here we use dynamic...
Visualize printing all 24 volumes of the Encyclopaedia Britannica on head a pin. In 1959, Richard Feynman articulated this reality in an insightful address at annual meeting American Physical Society. what became prophetic speech, “There's plenty room bottom” 1, discussed manipulating and controlling matter small scale. Back then, forward thinking conjured images going to moon era when computers occupied entire floors buildings. Fifty years later, we no longer have imagine. We are actively...
Due to growing production, carbon nanotubes (CNT) may soon be found in a broad range of products and thus the environment. In this work, an algal growth test was developed determine effects pristine oxidized CNT on green algae Chlorella vulgaris Pseudokirchneriella subcapitata. suspensions were prepared medium characterized taking into account suspension age, reduced light transmittance nanoparticle defined as shading quantified by UV/vis spectroscopy, agglomeration cells. Growth inhibition...
