Improving air quality reduces dementia risk, multiple studies suggest
Improving air quality may improve cognitive function and reduce dementia risk, according to several studies reported today at the Alzheimer’s Association International Conference (AAIC), June 26-30, 2021, in Denver and virtually.
Previous reports have linked long-term air pollution exposure with accumulation of Alzheimer’s disease-related brain plaques, but this is the first accumulated evidence that reducing pollution, especially fine particulates in the air and pollutants from the burning of fuel, is associated with lower risk of all-cause dementia and Alzheimer’s disease.
Both increasing levels of air pollution and increasing cases of dementia are worldwide public health crises. While research has linked air quality and cognition previously, these new data atAAIC 2021 explore how air pollutants might impact dementia and what reducing them might mean for long-term brain health. Among the key findings are:
- Reduction of fine particulate matter (PM2.5) and traffic-related pollutants (NO2) per 10% of the Environmental Protection Agency’s (EPA) current standard over 10 years was associated with 14% and 26% reductions in dementia risk, and slower cognitive decline, in older U.S. women. These benefits occurred in women regardless of their age, level of education, the geographic region where they lived and whether they had cardiovascular disease.
- Reduction of PM2.5 concentration over 10 years was associated with a reduced risk of all-cause dementia in French individuals by 15% and of Alzheimer’s disease by 17% for every microgram of gaseous pollutant per cubic meter of air (μg/m3) decrease in PM2.5.
- Long-term exposure to air pollutants was associated with higher beta amyloid levels in the blood in a large U.S. cohort, showing a possible biological connection between air quality and physical brain changes that define Alzheimer’s disease.
“We’ve known for some time that air pollution is bad for our brains and overall health, including a connection to amyloid buildup in the brain,” said Claire Sexton, DPhil, Alzheimer’s Association director of scientific programs and outreach. “But what’s exciting is we’re now seeing data showing that improving air quality may actually reduce the risk of dementia. These data demonstrate the importance of policies and action by federal and local governments, and businesses, that address reducing air pollutants.”

Saltworks’ advanced membrane plant shows 98% water recovery in pilot plant
Saltworks’ ultra-high recovery membrane pilot plant operated continuously around-the-clock for 90 days, achieving 98% water recovery from a complex, mixed industrial wastewater with high organics and variable water chemistry.
The advanced pilot plant crossed the Pacific Ocean with a quick turnaround after its cooling tower blowdown trial at an agri-chem facility, for which Saltworks is now designing and building a full-scale, permanent installation.
Saltworks’ pilot team operated the plant both on-site and remotely despite the ongoing COVID-19 pandemic. Nitto HYDRANAUTICSTM PRO-XP1 membranes were employed along with Saltworks’ advanced process technologies.
The system treated variable water quality originating from multiple streams, consistently achieving 98% recovery and concentrating a sodium sulfate-rich brine to over 200,000 mg/L total dissolved solids (TDS). The 2% brine volume is small enough such that direct solidification becomes viable, avoiding the need for an energy-intensive evaporator-crystallizer.
As the need for ultra-high recovery industrial water recycling grows, Saltworks’ envisions end-user industries from microelectronics to brackish water desalination, lithium refining, and oil and gas processing.
Evonik supplies membrane technology in support of Germany’s largest biogas plant
In Germany’s largest biogas plant so far, plant operator EnviTec Biogas relies on Evonik’s patented SEPURAN Green membrane technology for efficient biogas upgrading.
At the EnviTec Biogas AG BioEnergie Park Güstrow (Germany), biogas will be liquefied into 9,000 tons of biomethane per year (Bio-LNG) beginning in the fall of 2022. The project of the biogas all-rounder based in Lohne and Saerbeck (Germany) is exemplary for supplying bio-LNG onsite as another immediately available renewable energy source in Germany. The climate-neutral fuel is made available for heavy-duty transport via the filling station networks of service station operators such as Liqvis and Liquind.
In the future, the approximately 500 GWh biogas processing plant in Güstrow will process 150,000 metric tons of predominantly agricultural waste into high-purity bio-LNG. In addition, the carbon dioxide (bio-CO2) separated from the biogas will be liquefied and made usable and storable as a natural raw material.
“We interconnect the membranes using Evonik’s patented 3-stage process for maximum efficiency in biogas upgrading, replacing the already obsolete pressurized water scrubbing technology,” said Olaf von Lehmden, CEO of EnviTec Biogas AG. “For more than ten years, we have been working with Evonik to implement biogas projects worldwide in various plant sizes and can look back on a success story that now includes more than 60 references.”
The SEPURAN Green hollow-fiber membranes from Evonik remove the carbon dioxide from the raw biogas, turning it into high-purity biomethane. The membranes are made of specially developed Evonik high-performance polymers that are highly resistant to pressure and temperature.
Compared with other biogas upgrading processes, such as pressurized water scrubbing, pressure swing adsorption, or amine scrubbing, Evonik’s membrane technology has significant advantages in that it requires comparatively little energy and does not need any auxiliary materials or chemicals. It produces no waste or wastewater that would otherwise have to be treated and disposed of.
Study finds Camfil air purifiers have four-fold increase in the removal of aerosols in poorly ventilated spaces
A study conducted by Camfil in conjunction with University College Dublin (UCD) and the Mater Misericordiae University Hospital (MMUH) has found that Camfil’s City M air purifiers remove aerosols from poorly ventilated rooms at four times the normal rate.
Experiments conducted by UCD’s Dr. Kevin Nolan of the School of Mechanical and Materials Engineering used the air purifiers to clean a 4m x 2.5m x 2.6 m room of aerosol. The room was filled using a smoke wand for 30 seconds. The experiments found that when untreated, aerosols dissipated over 500 seconds. When the City M air purifier was at its maximum speed, the aerosol was cleared in under 160. When a small heater was used to provide added natural convection flow, the untreated aerosol particles dissipated in 800 seconds, which was reduced to below 200 seconds with the use of Camfil City M.
“We are very grateful to Camfil for allowing us to use their City M air purifiers for these experiments,” said Dr. Nolan. “Since the outbreak of COVID-19, it has become more and more important to test new methods of keeping our indoor spaces clean and free from airborne particles. Camfil’s City M air purifiers have proven to be highly effective in removing the presence of aerosols quickly and efficiently, creating a healthier and safer environment. Conducting these experiments at the Mater Misericordiae Hospital in Dublin has allowed us to display how hospitals can benefit from the use of top-quality air purifiers to protect patients and staff.”
High-Efficiency Particulate Air (HEPA) technologies such as the City M air purifier are capable of reducing the circulation of airborne particulate matter, including airborne aerosols that transmit COVID-19 or, like PM2.5, are a leading cause of cancer.
“Since 1963 Camfil has been committed to educating the public about the importance of clean air, and to providing top quality solutions to protect people, processes and the environment,” said Paul Flanagan, Managing Director of Camfil Ireland. “The past year and a half have made our mission and purpose more important than ever before, as the idea of clean air has become a top priority for people. While COVID-19 is likely to be a temporary disaster, air pollution has become a permanent fixture for people all over the world. While removing the harmful pollutants is not an easy task, protecting our environment is; we are determined to show people that installing HEPA filters into buildings can and will decrease the risk of inhaling harmful pollutants. This fantastic study by UCD is proof of the success of Camfil’s filters.”

Korea Institute of Civil Engineering and Building Technology develops alternative seawater desalination nanofiber membrane
The Korea Institute of Civil Engineering and Building Technology (KICT) has announced the development of a stable performance electrospun nanofiber membrane to turn seawater into drinking water by a membrane distillation process.
The research team, led by Dr. Yunchul Woo, has created co-axial electrospun nanofiber membranes fabricated by the alternative nano-technology of electrospinning. The technology can prevent wetting issues and also improve long-term stability in the distillation process.
The research team used poly(vinylidene fluoride-co-hexafluoropropylene) as the core and silica aerogel mixed with a low concentration of the polymer as the sheath to produce a co-axial composite membrane and obtain a superhydrophobic membrane surface. Silica aerogel exhibited a lower thermal conductivity compared with that of conventional polymers, which led to increased water vapor flux during the membrane distillation process due to a reduction of conductive heat losses. The research team applied the membrane distillation process using the fabricated co-axial electrospun nanofiber membrane for 30 days, performing at a 99.99% salt rejection.
“The co-axial electrospun nanofiber membrane have strong potential for the treatment of seawater solutions without suffering from wetting issues and may be the appropriate membrane for pilot-scale and real-scale membrane distillation applications,” said Dr. Woo.
The membrane is suitable for long-term membrane distillation applications with a low sliding angle, low thermal conductivity, the ability to avoid temperature polarization, and a reduction in wetting and fouling problems whilst maintaining super-saturated high water vapor flux performance.
