The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.

The study showed that in stormwater runoff during rain approximately 19 out of every 20 microplastics collected were tire wear particles with anywhere from 2 to 59 particles per liter of water. Tire rubber contains up to 2500 chemicals with the contaminants that leach from tires considered more toxic to bacteria and microalgae than other plastic polymers.

Racial and ethnic minorities -- and Black people in particular -- still experience disproportionately high rates of cardiovascular disease-related deaths caused by exposure to fine particulate matter, according to the research.

The fumes can cause irritation and inflammation in the body.

Using satellite data, researchers have shown that the relationship between water droplets in clouds and aerosol concentration is more non-linear than previously thought. Specifically, in heavily polluted regions, the additional warming of the Earth resulting from better air quality could occur much later than originally believed -- perhaps as much as 20 or 30 years later than expected.

Their exposure to the smoke in June 2023 from Canadian wildfires led to only a slightly higher bump in visits to New York City hospital emergency departments for breathing problems or asthma attacks than what is seen on days when pollen counts are high. However, authors of a new study say other possible health effects, such as possible heart attacks and stroke, still need to be investigated.

Scientists have designed catalyst-coated lampshades that transform indoor air pollutants into harmless compounds. The lampshades work with halogen and incandescent light bulbs, and the team is extending the technology so it will also be compatible with LEDs.

According to a new study, microplastics are not only carried by the wind, but also escape into the atmosphere from seawater. Researchers present data on the composition and sources of different types of plastic in the air over the North Atlantic and the origin of the particles.

The models may help public health officials develop strategies for reducing exposure to unhealthy air quality.

Like predictions for hurricane and wildfire seasons, the forecasts could help the government prepare resources and implement policies to mitigate the severity of the season.

The work, which focuses on the role of 'dark brown carbon' -- an abundant but previously unknown class of particles emitted as part of wildfire smoke -- highlights an urgent need to revise climate models and update approaches for the changing environment.

In a cohort study of millions of Medicare beneficiaries, the researchers found that exposures to PM2.5 and NO2 over a 10-year period increased the risk of developing colorectal and prostate cancers. The researchers also found that even low levels of air pollution exposure may make people particularly susceptible to developing these cancers, in addition to breast and endometrial cancers.

These in turn were linked to near-instant decreases in local heart-related emergency department visits and hospitalizations for cardiovascular diseases, a new study shows. The impact of the closure persisted through at least December 2018, the last month for which data were analyzed.

Residents were worried about their health and the environment, so researchers have been assessing the local air quality with stationary and mobile sampling methods. Now they report that some gases, including acrolein, reached levels that could be hazardous.

To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.

And yet, quantifying those losses at a large scale hasn't been possible, in large part due to a lack of the required infrastructure. But a new study shows that a major source for such information already exists in the form of environmental DNA (eDNA), which has been inadvertently collected in filters by thousands of ambient air quality monitoring stations in countries around the world for decades.

Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.

A new study reveals that the adverse health effects of fine particulate matter (PM2.5) are attributable to the conversion of peroxides into more reactive species such as the hydroxyl radical (OH) rather than the direct chemical production of hydrogen peroxide (H2O2) as previously thought.

Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin. They found that bush fires and burning savannah in the north and south of Africa make a substantial contribution to air pollution in the central Amazon all year round, thereby playing an important role in the earth radiation budget and water cycle. This is caused by the efficient transatlantic transport of particles through the atmosphere.

They used this model to understand why storm geysers form, what conditions tend to make them worse, and what city planners can do to prevent them from occurring. The authors say the best cure for a storm geyser is bigger pipes; however, that advice is little help to cities with existing pipeline infrastructure. In these systems, the focus must be on minimizing the potential damage by reducing the height of the geysers, the volume of expelled water, or the resulting damage to the pipeline.

Today, scientists report an eco-friendly alternative -- a plant-based film that cools when exposed to sunlight and comes in many textures and bright, iridescent colors. The material could someday keep buildings, cars and other structures cool without requiring power. 2023年3月27日,星期一,11:49:20美国东部时间 //www.koonmotors.com/releases/2023/03/230327114920.htm //www.koonmotors.com/releases/2023/03/230327114824.htm Filters fitted to vehicle exhaust systems to remove particulate matter pollution have limited impact on ultrafine particles, new research shows.

The study also found financial penalties for power plants can significantly reduce people's pollution exposure, except during severe heat waves.

Now a new study confirms it can do exactly that.

As coal-fired plants cause environmental and health hazards, technologies such as swirl flow and air staging have been proposed to mitigate the pollutants in their emissions. However, it is unclear how effective these technologies are in reducing the environmental costs of these plants. Now, researchers have provided insights on this front in a new study, delineating their efficacies with experiments and simulations.
