A product for the removal of micro-pollutants from wastewater is the Overall Winner of the Aquatech Innovation Award 2025. Then a little bit of ozone is added to avoid the formation of bromates. This is as close to a natural process as possible and using activated carbon and ozone in a responsible and smart way.
China is a night-time ‘hot-spot’ for the production of nitrate radicals (PNO3) that could have a major impact on health-threatening ozone and fine particulates (PM2.5) Experts believe that this increase will have significant air pollution implications for China and other developing countries such as India. Increased O3 and PM2.5
Environmental and engineering consultancy Ricardo is applying its expertise in air quality measurement to enable local authorities across Greater Manchester to monitor the contribution to air pollution from wood burning stoves, raise public awareness of its risks, and reduce its impact on people’s health.
This, in turn, is believed to have had an effect on pollution levels in the atmosphere. At the same time, says the group, this collection of data allows scientifically substantiated predictions to be made about the pollution levels of future mobility scenarios. In contrast, ozone levels increased.
Recently-launched water filtration and air purification company Aqua Perfecta is developing a UK postcode checker for customers to measure air pollution and help the company offer advice on air purifying products. and PM10 concentrations at their homes, using the online postcode checker.
A team led by environmental physicist Stefan Schreier at the University of Natural Resources and Applied Life Sciences in Vienna is attempting to build up a better picture of nitrogen dioxide pollution in the city. The group is using MAX-DOAS instruments mounted on top of buildings to build a more accurate map of pollutant distribution.
Alerting PRThe development means the likes of local authorities, construction site managers, and transport professionals will be able to rapidly respond to high concentrations of air pollution. Users will also be able to generate warnings for episodes that last over 15 minutes, 30 minutes and one hour.
Ozone levels near the surface in urban environments are lower than expected, in the results of an Austrian research group The 40-meter-high monitoring tower of the Innsbruck Atmospheric Observatory near the centre of the city of Innsbruck continuously provides data on the composition of the atmosphere at ground level.
Now, we can add air pollution to the list of threats. Our research from 2022 revealed that when exposed to two common air pollutants at concentrations within EU air quality limits , the visits of pollinating insects to flowers plummeted by as much as 90%. We were surprised by what we found. CLICK TO ENLARGE.
This year's installation of the American Lung Association's State of the Air report gave Los Angeles, Orange, Riverside, San Bernardino and Ventura counties an F in particle and ozonepollution.
Record hot temperatures in the UK over the summer caused significant changes to the levels of harmful pollutants such as ozone and particulate matter, prompting a number of novel observations by the National Centre for Atmospheric Science (NCAS). Ozone events and their origins.
Common air pollutants from both urban and rural environments may be reducing the pollinating abilities of insects by preventing them from sniffing out the crops and wildflowers that depend on them, new research seems to show. The theory is that the pollutants react with and change the scents of flowers, making them harder to find.
Los Angeles is a hub of freight activityand (not coincidentally) the home of the worst ozonepollution in the nation. Electrifying trucks in La-la Land will deliver an outsize benefit in emissions reduction.
Dirty windows can harbour potentially harmful pollutants under protective films of fatty acids from cooking emissions – and these can hang around over long periods of time. In addition, toxic pollutants can become trapped underneath this persistent crust and are then protected from breakdown in the atmosphere.
A laser-based technology developed at TU Graz can provide continual real-time analysis of air pollutants and their interaction with other gases and sunlight – with revolutionary import, suggest the group. A well-known example is the formation of ground-level ozone when UV light hits nitrogen oxides.
Air quality expert EarthSense has announced a new release of its MappAir® high-resolution map of air pollution, with powerful new features and improved scalability from global down to 10 metres or street level. Furthermore, MappAir® now offers a three-day pollution forecast for the entire globe,” continued Dr. Jeanjean.
A new Stanford University-led study seems to reveal that removing one thing in particular – a common air pollutant – could lead to dramatic gains in crop yields. Nitrogen oxides, or NOx, are among the most widely emitted pollutants in the world. A NOx-ious problem. Image credit: Lobell, et al. Science Advances.
Launched in November 2022, and funded by a UK Research and Innovation (UKRI), the project examined the link between air pollution, behaviour and the cost of air pollution-related healthcare in the Sandwell area. Kate Barnard said: “With every breath we take, both our health and the economy suffer from the burdens of air pollution.
SB24-230 offers a tremendous opportunity to fund transit service through a fee on oil and gas production in Colorado—linking a key source of climate and ozonepollution with a key solution.
and PM10 particulate matter is a particular concern with this kind of pollution, although the smoke would be expected to include other toxic pollutants including carbon monoxide, VOCs, nitrogen oxides, and polycyclic aromatic hydrocarbons (PAHs). And for smaller rooms, air purifiers can be used to reduce indoor air pollution levels.
The team also investigated the responses of receiver plants under elevated ozone conditions, which represents the situation in more polluted regions. This research sheds new light on the dynamism of conifer communication and shows that the process can be substantially altered by air pollution.
Air pollution is not a new problem in the UK – the London smog of 1952 killed 12,000 people. Since then, the effects of climate change, major industry and lifestyle changes have altered the air that we breathe, for example, coal-burning has dramatically declined, while increased road transport has led to new air pollutants.
A University of Liverpool study of air pollution in the UK during the first 100 days of lockdown seems to show that whilst nitrogen oxide levels were cut by half, levels of sulphur dioxide increased by over 100%. and ozone, and to compare the data to the past seven years. and ozone, and to compare the data to the past seven years.
Dr Rosa Busquets is Associate Professor in Analytical Chemistry and Forensics at Kingston University What are microplastics, why are they such a problem and what can be done to reduce the pollution they cause? Everybody knows the pollution plastic is causing, so the question has to be why are shops and other retailers still using it?
Volatile organic compounds (VOCs) combine with nitrogen oxide to create ozone, a key precursor to smog. In 2010, the Central Government of China integrated the "Guideline on Strengthening Joint Prevention and Control of Atmospheric Pollution to Improve Air Quality" into its 12th Five Year Plan.
while minimizing the ozone generation typically produced by plasma, according to the group. Additionally, the combined NTP and WS system can minimize or eliminate secondary air pollution by capturing ozone and other gaseous intermediate organics, which are by-products of the NTP process.
Today, Kansas City will experience its first ozone alert day of the season. Here’s what you need to know to protect your health and help reduce pollution. When ozonepollution is high, the air is unhealthy. Ozonepollution can cause wheezing, coughing and difficulty breathing. or after 7 p.m.
The compromise was hailed as a “grand bargain” that balanced industry priorities with the need for environmental reforms in a state with mounting air pollution woes. Ground-level ozone — the key component in smog — results when certain pollutants react with sunlight.
The rising level of pollution is leading to a major increase in environmental concerns. Increasing fossil fuel usage adds to the carbon footprint, further depleting the ozone layer. Increasing fossil fuel usage adds to the carbon footprint, further depleting the ozone layer. billion by 2030, at a CAGR of 17.51%.
These deniers accept that humanity’s pollution has disrupted a fundamental, complex and awesomely powerful planetary system with a history of violent shifts, yet they express complete confidence that the global changes we are inadvertently unleashing will be harmless, even beneficial.
An emerging class of personal air quality monitoring devices fills a need for people who care about pollution exposure in their immediate vicinity. The on-board hardware includes relatively simple MEMS semiconductor sensors, of a kind that have been developed principally for the detection of pollution from automobile exhausts.
For example, in 2015, the UK’s Committee on the Medical Effects of Air Pollutants (COMEAP) reviewed the available evidence and concluded: “Studies have shown associations of NO2 in outdoor air with adverse effects on health, including reduced life expectancy. Ozonator design. NOx measurement in product development. NO2 converter.
It’s a primary hub for fleet operations, and—not surprisingly—has some of the worst air pollution in the US. San Bernardino and Riverside counties recently ranked number one and two in the nation for the worst ozonepollution. “We
In Colorado, fossil fuel interests are vigorously opposing legislative bills meant to clean up the state’s heavily polluted air. The Colorado Springs area received failing grades for ozone in 2024. Instead, several have retained fossil fuel lobbyists to work on their behalf.
When people are asked to explain climate change, many think it has something to do with the hole in the ozone layer. Marshall says, “More than four in 10 Americans think the ozone hole actually causes global warming. And so many of them remember and understand so much about ozone depletion. Why is that? But there's good news.
The cores, which provide a historic record between 1957 and 2017, provide evidence that levels of these chemical pollutants have shown a marked increase in the remote snowpack of Antarctica over the last few decades. The Montreal Protocol certainly provided huge benefits and protection to the ozone, the climate and to us all.
These VOCs contribute to ground-level ozone and smog, which can cause respiratory issues and environmental damage. However, using winter blends in summer would lead to higher emissions and worse air quality, particularly in urban areas already struggling with pollution. Final Thoughts Summer gasoline blends exist for a reason.
The project aims to help identify pollution hot spots caused by traffic. Part of the government’s Automatic Urban Monitoring Network, the reference station has monitored ozone, NOx and fine particulates since 2017. Until recently, there was just a single continuous air quality monitoring station in or near Northampton.
In addition, diesel engines burn fossil fuels releasing carbon dioxide, a greenhouse gas (GHG), as well as other pollutants, such as nitrogen oxides (NOx). Some oxides of nitrogen are not GHGs but they do perform a role in the formation of tropospheric ozone which is a GHG.
A new method for clearing organic pollutants from wastewater uses hydrogel granules made from polyvinyl alcohol (PVA), which function as a biological carrier for microorganism cultures. The granules function by decomposing the pollutants in question – a treatment method said to work up to five times faster than conventional approaches.
As the phrase ‘forever chemicals’ enters the Oxford English Dictionary for the first time in 2024, and these fluorinated substances expand the list of micropollutants, it might be time for a change in the way these persistent environmental pollutants are tackled. Some use technologies like ozone oxidation, and membrane filtration.
Part of the government’s Automatic Urban Monitoring Network, the reference station has monitored ozone, NOx and fine particulates since 2017. It will also make the invisible visible; identifying pollution hot-spots and helping drivers for example, to understand the impact of idling during drop-off and pick-up times at schools.”
Researchers reveal NO2 emission reductions during first lockdown were lower than previously thought, amidst warnings ozone levels actually increased. Importantly, our study has provided a new framework for assessing air pollution interventions, by separating the effects of weather and season from the effects of emission changes," he said.
Due to its climate and indirect health impacts (methane is a precursor for ozone which is an air pollutant that damages human health and crops), methane mitigation has recently become a global policy priority.
