This paper summarizes a study comparing the environmental impacts of reusable hospital gowns coated with nanoscale silver to single-use disposable gowns. The study models the life cycle impacts of a commercial nanosilver treatment applied to reusable polyester gowns using a proprietary process. Key findings include that the environmental impacts of the nanosilver-enabled reusable gowns are equal to disposable gowns after 12 wearings. The results suggest nanosilver textiles could reduce the environmental impact of hospitals while preventing infection.
This document discusses the use of disposable microfiber cloths (D-MFCs) for cleaning clinical equipment at a large metropolitan health service. A study found that D-MFCs and reusable microfiber cloths were able to remove fluorescent markings and viable bacteria like vancomycin-resistant Enterococcus, while standard paper towels and detergent wipes were not as effective. The health service was then able to transition to using D-MFCs for cleaning sensitive equipment that could not be disinfected with hypochlorite solution. This provided a superior cleaning system and allowed all clinical equipment to be used, even for patients infected or colonized with multidrug-resistant organisms.
Evaluation of biological and physicochemical risk of hospital liquid waste in...Agriculture Journal IJOEAR
— Hospitals could be the source of pollution that must be taken into account in a general approach to health and environmental risk assessment. This study is part of the characterization of hospital liquid waste in a region in Morocco, whose objective is to assess their physicochemical, bacteriological and toxicological quality. The physicochemical analyzes carried out on 144 samples taken during one year showed a great fluctuation of some parameters such as: BOD5, COD, MES, PH, T°, as well as an important bacteriological load: Total coliforms, E coli, faecal Streptococci, pathogenic germs such as: Salmonella, Staphylococcus, 20% multi-resistant, virulent germs of emerging nature such as: Pseudomonas aeroginosa, and trace metal elements such as: mercury and copper that exceed the threshold of acceptability. At the end of this study, it turned out that hospital effluents are heavily loaded with pollutants. We therefore hope, in the light of the results provided by this study, to have generated a real awareness of the competent authorities on strengthening and improving the treatment of hospital liquid effluents such as developed countries, as the impact of these effluents on human and environmental health is harmful and can spread emerging diseases.

Design and Materials Selection: analysis of similar sanitary pads for daily useIJERA Editor
Hygiene practices have effects on vulvovaginal microbiota. Specific products for intimate female hygiene are available in the market, such as the sanitary pads. Since these pads were introduced in the market , they became the focus of research that seek to improve their shape, manufacturing processes and the properties of materials used in order to provide more benefits to users. Thus, the present study aimed to characterize the fabrics used in daily sanitary pads, focusing on the development of future products. The spectra generated by FTIR/ATR suggest that the samples were composed of polypropylene. The photomicrographs showed that the polymeric outer layer was made of nonwoven fabric manufactured by spunbond and point bonding processes.
Nanotechnology and the environment: A mismatch between claims and realityYuyun Ismawati Drwiega
The document summarizes concerns about claims of environmental benefits from nanotechnology not matching reality. While proponents claim nanotechnology will provide cleaner production and reduce pollution and energy use, evidence suggests the environmental costs of nanomaterial production often outweigh potential gains. Manufacturing nanomaterials requires large amounts of energy and water and produces toxic waste. Many nanomaterials themselves are toxic to the environment. The document calls for better governance of technological innovations to guide them in publicly acceptable directions through comprehensive risk and life cycle assessments.

Metal Nanoparticles and their Safety Processing in Functional FoodsAl Baha University
This document provides a review of metal nanoparticles and their safety processing in functional foods. It discusses various nanomaterials used in food industries and their potential health effects. Some key points include:
- Nanoparticles like zinc oxide and silicon dioxide are considered safe for use as food additives by regulatory agencies. However, more research is still needed on their long-term safety.
- Nanoparticles can increase the bioavailability of nutrients like iron. Silver nanoparticles also show potential as antimicrobial agents in food packaging.
- Further research is needed to establish exposure limits for nanoparticles in occupational settings and develop standardized monitoring methods. Predictive models are also needed to evaluate nanoparticle toxicity.
- Many nanoproducts
1) The document examines the antimicrobial activity and thermophysiological properties of cotton, bamboo, and organic cotton fabrics treated with an alginate/copper solution using ultrasonic energy.
2) Testing found the alginate/copper treatment significantly improved the antimicrobial activity of cotton and organic cotton fabrics against common bacteria, as demonstrated by larger zones of inhibition, but did not improve the antimicrobial activity of bamboo fabrics.
3) Thermophysiological testing revealed the alginate/copper treatment significantly changed the properties of cotton fabrics but did not affect bamboo fabrics.
This document discusses potential applications of nanotechnology across many fields. It begins by defining nanotechnology as the study and control of matter at the atomic and molecular scale, generally 100 nanometers or smaller. It then outlines several implications and applications of nanotechnology in areas like medicine, energy, environment, information/communication, aerospace, construction, and more. The document raises some health and environmental concerns regarding nanotechnology and discusses further research needed for many applications.
The document summarizes a study that evaluated the antibacterial activity of zinc oxide (ZnO) nanoparticles coated onto cotton fabrics. ZnO-coated cotton fabrics were prepared using a sonochemical coating process. The antibacterial activity of the fabrics was then assessed against both gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacteria using several test methods, including agar diffusion, shake flask, and absorption methods. The results showed the ZnO nanoparticle-coated fabrics exhibited significant antibacterial activity against both bacterial strains, with slightly higher activity observed against S. aureus compared to E. coli.
Although nanotechnology has been recognized as an enabling technology, human and environmental exposure to nanomaterials is inevitable. As such, the need to ensure that the technology and its various applications are safe is paramount. The current concern on the risks of nanotechnology tends to specialize in the potential dangers of nanomaterials and nanoparticles. The ability to predict and mitigate potential health effects is crucial for sustainability of nanotechnology. This paper introduces the reader to safety in nanotechnology. Matthew N. O.

The document summarizes a study comparing the efficacy of two common environmental sampling devices used in compounding pharmacies: flat paddle samplers and round contact plates. The study found the devices perform equally well based on their ability to: 1) lift and grow dried microbes from surfaces, and 2) maintain the nutritive properties of their agar media over time. Either device is suitable for regular environmental monitoring to ensure sterility as required by industry standards and regulatory agencies.
Efficiency of Donning and Doffing Medical Examination GlovesCSCJournals
Quickly donning and doffing medical gloves is of vital importance for high-pressure environments. The efficiency of glove donning, however, is sometimes hindered because of moisture on the hand. A variety of commercial glove coatings exist that are said to enable a smoother donning process, however, no previous studies have examined the differences in time taken to don or doff gloves manufactured using different materials and coatings. The aim of this new study was to compare the efficiency of donning and doffing different glove types. 14 participants were timed on their efficiency to don and doff chlorinated latex and nitrile gloves, as well as polymer coated latex and nitrile gloves. All glove types were studied in both dry and wet hand conditions, leading to a total of 8 different glove condition combinations. The results indicate that polymer coated latex gloves are desirable when a quick glove change is required as there was no statistically significant difference between the average time taken to don these gloves in dry and wet hand conditions. Higher incidences of sticking were found among the wet hands, particularly in the polymer coated nitrile, which took the longest to don. However, little differences were found between all glove types, suggesting that neither the material itself, nor the internal coating, have an effect on the overall donning process when hands are dry. Discrepancies in best fit size were also noticed between the recommended sizes based on anthropometric measurements and the participants preferred glove size.
Several studies have found that warm air hand dryers are more hygienic than other drying methods like paper towels. They reduce bacteria and viruses on hands more effectively due to the warm air penetrating crevices and dehydrating the skin faster. While one study funded by paper towel makers found otherwise, it had flawed methodology and was not peer reviewed. Most medical research has concluded that warm air dryers do not spread more bacteria in the air and may reduce it compared to other surfaces in washrooms.
1) Copper-infused patient gowns and linens have been shown in multiple peer-reviewed studies to lower infection rates of harmful bacteria like MRSA and C. difficile.
2) A study across 6 hospitals found infection rates reduced by 40-60% when copper gowns and linens were used.
3) Similarly, a study of over 175,000 patient days across 12 hospitals saw infection rates drop significantly with the use of copper textiles.
