Sullivan shares thoughts on fragrance products in Yahoo

MechE’s Ryan Sullivan shares his thoughts on fragrance products in Yahoo. Currently, the industry lacks regulations for companies to disclose the ingredients in their products, potentially exposing consumers to harmful chemicals when lighting a candle or spritzing a room with room spray. “Products can contain dozens of chemicals, and all it shows up as is one word on the ingredient list: fragrance,” he says. This story was also covered in The Guardian.

Sullivan weighs in on water microdroplet chemistry
Chemistry World

MechE’s Ryan Sullivan spoke with Chemistry World about the contentious topic of water microdroplet chemistry, which has inspired mixed feelings among researchers in the field. Sullivan, for his part, is more skeptical. “Many physical atmosphere chemists who I regard as very careful experimentalists…do not think that this idea that oxidants are spontaneously being produced in microdroplets is real—they are quite convinced it’s contamination or some sort of artifact,” said Sullivan.



Donahue comments on Kentucky train derailment fire
AP News

ChemE/EPP’s Neil Donahue comments on a Kentucky train derailment fire in AP News. Sulfur dioxide was thought to be released during the crash, prompting the residents of Rockcastle County to be evacuated. “It is just nasty, caustic, and acidic stuff that hurts. It’s unpleasant to be in,” Donahue says. “Once the fire was put out, the threat from the chemicals was expected to diminish quickly.” Donahue was also featured in The Washington Post on the topic.

ChemE/EPP’s Neil Donahue was recently featured in a podcast posted by the Royal Society of Chemistry. In the “Intro to Air Pollution” episode on the show Brought to you by chemistry,  he talks about air quality and how pollution canaffect the body. “Even in places where there have been great improvements in air quality, and I live in one, it’s still a major cause of death. And, in the developing world, it’s a really big issue,” he says.

The Hill

ChemE/EPP’s Neil Donahue comments on “climate havens” with The Hill. Cities around the U.S. are marketing themselves as safe places from extreme climate changes; however, experts believe that no place will be immune. “It’s an absurd concept with a grain of truth,” Donahue says.


Donahue discusses effects of chemicals from East Palestine train derailment
AP News

ChemE/EPP’s Neil Donahue discusses the effects of vinyl chloride and dioxins from the East Palestine train derailment with AP News. “Vinyl chloride is bad, dioxins are worse as carcinogens and that comes from burning,” he says. Recent testing indicates a low chance of dioxins being released, but environmentalists and Ohio residents are still pushing for the banning of vinyl chloride.


Presto collaborates on Ohio train derailment research
NBC News

MechE’s Albert Presto collaborated on new research regarding chemicals released during the Ohio train derailment, finding high levels of acrolein, a chemical known to cause lung damnage and abnormal lesions after long-term exposure. Presto calls this find “a little bit surprising” and noted the difficulty to link any one chemical to specifical health concerns.

Donahue talks smoke, air quality in Pittsburgh
The Hill

ChemE/EPP’s Neil Donahue acknowledges Pittsburgh’s historic reputation as the “Smoky City” while discussing current air quality issues. Donahue compares recent Pittsburgh air quality levels to be “as bad as it was every now and then in 2000, and practically every day in 1974.”

Donahue explains Pittsburgh summer temperatures
The Hill

ChemE/EPP’s Neil Donahue explains Pittsburgh’s cooler summer temperatures in an interview with The Hill. “We are close enough to the Atlantic and the Gulf Stream to get some of the moderation associated with being more coastal,” Donahue says. “We are not all that far north of the Mason-Dixon line, but we are definitely not South.”

Presto discusses health concerns of Canadian wildfires with KDKA CBS News Pittsburgh
CBS News KDKA Pittsburgh

MechE’s Albert Presto discusses the health concerns associated with the Canadian wildfires with KDKA CBS News Pittsburgh. The fires have only exacerbated the effects of the normal city air quality, including eye and lung irritation. “All the activities that contribute to that baseline that we already have are still happening. We’re still burning fossil fuels. We’re getting this wildfire smoke on top of our normal load,” he says.

Donahue talks Canada wildfire smoke with The Hill
The Hill

ChemE/EPP’s Neil Donahue talks with The Hill about the Canada wildfire smoke and his predictions of when it will dissipate. The incoming rainfall will help flush out the particles in the air, allowing the smoke to disperse in “probably another day or two, according to the forecast,” he says.

Donahue comments on air pollution challenges

ChemE/EPP’s Neil Donahue was quoted by Vox in a story about recent air pollution challenges. “Obviously wildfires occur in nature, but their frequency and their severity and everything else is affected by us, by human activity,” Donahue said.

Presto discusses mask efficacy for wildfire smoke and smog

MechE’s Albert Presto explains that cloth or disposable face masks may help to block some particulate matter, but it’s most likely not enough as protection for your lungs. Presto encourages people to think of masks as a “ranked order,” noting options like neck gaiters are not effective in providing protection from smoke.

Donahue talks to Delaware Valley Journal about new carbon sequestration bill
Delaware Valley Journal

ChemE/EPP’s Neil Donahue talks to the Delaware Valley Journal about Pennsylvania’s new bill that focuses on carbon sequestration and storage as a solution for reducing carbon emissions. CO2 gas would be compressed, then stored, in underground rock formations which “have held the gas and oil (and CO2) for millions of years. So shoving new CO2 into them probably would work,” Donahue says.

ChemE/EPP’s Neil Donahue was interviewed by Healthline on the health risks of increased particulate matter in the atmosphere due to air pollution. According to Donahue, about 100,000 deaths in the U.S. can be attributed to air pollution each year. Donahue pointed out a particular particle, PM2.5 that he says “causes more than 10% of all deaths around the world.”
