Here is a selection of some of our favourite materials and nanotechnology research in 2021. We are seeing a growing number new materials made by processing wood, and another one that caught our eye in 2021 was the use of a fungus to make wood much more piezoelectric – and therefore capable of generating useful amounts of electricity.
Medium- and heavy-duty vehicles (MHDVs), like the big rigs on our highways and the vans that deliver our packages, make up just over 1 in 10 of the vehicles on our roads, but are responsible for over half of ozone-forming nitrogen oxide pollution and lung-damaging fine particulate pollution from on-road vehicles.
California's summer of 2021 has seen record-breaking wildfire outbreaks, surpassing 2020 by over 500 fire events by mid-July. Over the period of 2020 and 2021, California has also experienced its two largest wildfires ever , the Dixie and August Complex fires. Levels of Ground-level Ozone Pollution Can Increase in Summer.
The CPDW is thought to be affected by the shift in the westerly winds around Antarctica which have increased in recent decades due to a combination of greenhouse gas forcing and the polar ozone hole ( Miller et al, 2006 ). Antarctic contributions to sea Level scenarios from DeConto et al (2021). eabf7787, 2021. Recent advances.
At a contentious board hearing on May 7, 2021, the South Coast Air Quality Management District (SCAQMD) approved a first-in-the-nation rule to regulate trucking emissions from warehouses by a 9-4 vote. These state and federal standards require areas to reach certain ambient concentrations of ozone to be considered in “attainment.”
In my opinion the press conference on 9 August 2021 didn’t do justice to the vast effort that went into it. In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere. C since the industrial revolution, however, other types of pollution have had a moderating effect on that warming.
The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 These air quality impacts are minimal compared with the major ozone reductions resulting from the 1998 SIP Call, which resulted in more than 80,000 megawatts of coal capacity being retrofitted with SCRs. ppb by 2025.
A federal appeals court on Friday dismissed a lawsuit brought by a utility-supported organization that sought to overturn the Environmental Protection Agency’s revised 2021 Cross-State Air Pollution Update Rule for ozone.
For some parts of the spectrum, the IR can be either absorbed by CO 2 or by water vapour or by clouds, but taking those overlaps into account we find that 50% of the greenhouse effect is from water vapour, 25% from clouds, and about 20% from CO 2 and the rest absorbed by ozone, aerosols, and other trace gases ( Schmidt et al, 2010 ).
The Basin does not meet the state or federal ambient air quality standards for ozone and particulate matter, and existing regulations have to date proved insufficient to bring the Basin into compliance. The SCAQMD is the local agency responsible for attaining these clean air standards in the Basin. Facility-Based Mobile Source Measures.
The book has some positive pictures too, such as one showing the dramatic global reduction in consumption of substances that damage the ozone layer as a result of the Montreal Protocol that was implemented in the 1980s. 2021 Bodley Head £16.99hb 208pp.
Clauser however takes that number, removes 80 and 20 W/m 2 for atmospheric absorption by ozone (!!) Unfortunately, this is the opposite of what has happened – cloud cover, albedo and reflected shortwave have all decreased over that time ( Fig 2a in Loeb et al, 2021). Clouding the picture So where does this leave us?
On June 4, the Department of Environmental Protection issued a Code Orange Air Quality Action Day for ozone for Saturday, June 5 in the southwestern counties of Allegheny, Armstrong, Beaver, Butler, Fayette, Washington, and Westmoreland. Posted: June 4, 2021] PA Environment Digest
Studies have also shown that fireworks can create a ‘burst’ of ozone formation, also harmful to human health. The blue line indicates the corresponding spike in indoor air quality following the Fourth of July: In 2021, researchers at the University of California substantiated these findings, stating that PM2.5
On October 26, 2021, the U.S. EPA states that Metalmark indicates that its initial testing in a small chamber using cigarette smoke resulted in “steep reductions in PM concentrations within 20 minutes, without the creation of byproducts such as ozone or volatile organic compounds.” According to EPA, Metalmark Innovations, Inc.
Over the past 15 years, Partners have avoided emissions of over 500 metric tons of ozone-depleting substances and roughly 100 million metric tons of carbon dioxide equivalent. On average, GreenChill food retailers maintain emissions rates that are approximately half the industry average.
Ohio EPA has proposed rules that will require additional Volatile Organic Compound (VOC) and Nitrogen Oxide (NOx) emission controls for certain manufacturing and industrial operations located in the Cincinnati and Cleveland 2015 ozone nonattainment areas. Like VOCs, NOx is a precursor compound which can form ozone.
On June 5, the Department of Environmental Protection issued a Code Orange Air Quality Action Day for ozone for Sunday, June 6 in the Lehigh Valley, Southwest and Southeast PA and the Susquehanna Valley. Conditions will be favorable for ozone concentrations on Sunday to climb into the code ORANGE range.
Instead, environmentalists were mainly concerned about the ozone layer, nuclear meltdown and chemical industrial pollution, the erosion of biodiversity and population explosion. In 2021 the world emitted 36.4 In June 1979, atmospheric carbon stood at 339ppm, just below the 350ppm level scientists believe to be safe.
On January 20, 2021, the Ohio EPA’s Division of Air Pollution Control (DAPC) hosted a “Program Advisory Group” (PAG) meeting via Microsoft Teams to inform interested stakeholders of recent and upcoming DAPC activities. This post focuses on Ohio EPA’s anticipated regulatory changes to address non-attainment of the 2015 Ozone NAAQS.
Given the limited amount of time EPA had to complete the rulemaking for the Revised Rule, we discern that EPA reasonably chose to use existing air quality modeling and contribution information to derive an appropriately reliable projection of air quality conditions and contributions in 2021.
A little while back Environmental Politics carried a review by Katarina Eckerberg of The Untold Story of the World’s Leading Environmental Institution: UNEP at Fifty by Maria Ivanova (MIT Press, 2021). But why has progress been so slow?
16 In Liberty-Clairton Area, Allegheny County -- Scranton Times Editorial: Ozone Layer Healing Makes Case For Regulation -- TribLive: Natural Gas vs. Electric? -- Committee Schedule TODAY’s Calendar Of Events DEP Advisory: DEP’s Cambria District Office still closed due to waterline break. TUESDAY Noon: Inauguration Of Gov.-elect
Conversions to clean diesel trucks and buses reduce large amounts of nitrogen oxide pollution from these vehicles, leading to less fine particulate matter and ozone formation. The recommended projects will also reduce hydrocarbons, carbon monoxide, and carbon dioxide. Click Here for a list of grants awarded.
Transportation generates 47 percent of nitrogen oxide emissions in Pennsylvania, contributing to the formation of ground-level ozone. The 2021 AFIG funded projects will put 87 cleaner fuel school buses, package delivery trucks, and other vehicles in use, and save an estimated 262,798 gasoline equivalents (GGE) from the atmosphere.
Carbon dioxide emissions are the leading cause of climate change, and nitrogen oxides contribute to the formation of ground-level ozone, which affects the health of children, older people, people with lung diseases such as asthma and emphysema, and people who work or are active outdoors.
Based on a late 2021 RMI brightfield analysis , The Future of Landfills is Bright , closed landfills could host more than 60 gigawatts of solar capacity—enough energy to power the entire state of South Carolina! These indexes take various environmental factors (ex: ozone, PM, Superfund, etc.)
Hydrofluorocarbons (HFCs) were developed and introduced in the late 1980s to serve as replacements for ozone-depleting substances (ODS) primarily used in the air conditioning, refrigeration, aerosols, fire suppression, and foam blowing industries.
The Department will re-evaluate this suspension of enforcement no later than July 31, 2023, to determine if the Program is needed to assist the Commonwealth in attainment and maintenance of the National Ambient Air Quality Standards in areas of this Commonwealth and the Ozone Transport Region. Posted: November 5, 2021] PA Environment Digest
They experience truck traffic and their diesel exhaust emissions, transient workforces, air pollution, including volatile organic compounds, particulate matter, ozone, oxides of nitrogen and fugitive methane emissions. What Do Communities Experience Now, what's a community's experience? There's often large withdrawals of surface water.
Waste Coal In July of 2021 a company by the name of Stronghold Digital Mining (Stronghold) filed an S-1 report with the Securities and Exchange Commission (SEC) disclosing plans to purchase three waste coal fired power plants and install 57,000 Application Specific Integrated Circuits (ASICs) dedicated to mining bitcoin.
This work has resulted in lower proposed emissions limits and decreased chances of ground level ozone pollution that can harm people’s health. Wolf for exceptional accomplishments in 2021. The DCNR, DEP and PennDOT employees were among 50 employees from 12 state agencies honored by Gov.

The air quality for this report was calculated using data reviewed by EPA from 2020, 2021, and 2022. That means it includes the extreme wildfires exacerbated by the fossil fuel industry that burned more than 4% of California in 2021 and 2022. Ozone, too, poses significant risks to respiratory health.
Bakersfield, Fresno, and Visalia are consistently ranked as cities with the worst particulate and ozone pollution , according to the American Lung Association. and ozone concentrations highlighting air quality issues in the Central Valley. Annual average PM2.5 Graphics from CalEnviroScreen 4.0
We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation. 5] Additionally, the reaction of these volatile chemicals contributes to ground-level ozone production, which, unlike ozone in the stratosphere, is hazardous to human health.
Fossil fuel emissions, such as particulate matter and ozone, contribute to respiratory and cardiovascular illnesses, as well as deaths. Phasing them out will help address climate change and lead to local health benefits from less burning of the fuels.
GW record from 2021. In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data. NO x also contributes to the formation of ozone (or “smog”), another toxic pollutant.
