Detroit Mayor Mary Sheffield recently appointed Ali Abazeed as the city’s new Chief Public Health Officer, saying he would be a part of creating a “health in all policies” approach to government.

“We’re really excited to get up and going and also to continue the good work that the department has done over the years, but also to upgrade the software of what public health can look like in the city of Detroit,” he shares. 

Abazeed previously created and led the city of Dearborn’s health department. He also worked as a public health advisor at the National Institutes of Health (NIH). 

Past policies shape today’s health issues

He says health is impacted by housing quality and environment. He hopes to work with the department’s staff of 280 people to create better health outcomes for Detroiters.

“The challenges that Detroit faces from a health perspective, those aren’t inevitable…  they’re created by decades, if not centuries of decisions made by man, policies that have been excluding people from opportunities,” he says.

Abazeed says the city focuses on a harm reduction approach by working with all city departments to connect the dots for people who live in the city. He says part of that will include having more health department officials out in the city.

“90% of your life expectancy happens in the communities where you live, learn, work, worship, play…  then it requires us to take that 90% collaborative approach across everything that we do at the city,” he says. 

Abazeed says Detroiters face health burdens like asthma, which he says require a multifaceted response. 

He says everyone is entitled to good health. 

“Understanding who has been disqualified, who has been sort of pushed to the side, and whether that’s… in Washington or Dearborn and now in Detroit, I think the work is relatively the same, even if it does take on a little bit of a different scale,” he says. 

What happens when the regulatory systems we depend on to protect us break down?

In February, President Trump signed an executive order invoking the Defense Production Act — a wartime authority — to guarantee the domestic supply of glyphosate, the active ingredient in Roundup, the world’s most widely used weedkiller. The order extends legal immunity to its producers. It came one day after Bayer proposed a $7.25 billion settlement to resolve tens of thousands of cancer lawsuits without admitting wrongdoing.

The World Health Organization classifies glyphosate as a probable carcinogen.

Separately, the Supreme Court hears oral arguments April 27 in a case that could shut down state-level Roundup lawsuits nationwide. The EPA faces an October deadline to rule on glyphosate safety — with most of its research staff gone.

Last month on The Metro, Harvard historian Naomi Oreskes explained how the landmark safety study behind Roundup was ghostwritten by Monsanto, cited by regulators worldwide for 25 years, and finally retracted after she and researcher Alexander Kaurov documented its influence. Since then, she has identified more scientific research ghostwritten by Monsanto.

To discuss, Oreskes, author of “Merchants of Doubt,” returned to The Metro to join Robyn Vincent.

As temperatures drop and snowfall increases this winter, Detroit’s road commissioners break out their plows and salt trucks in order to maintain safe roadways. 

However, the most common road salt used, sodium chloride, has been known by experts and road commissioners to cause damage to surrounding trees.

Dr. Bert Cregg, a Michigan State University Professor in the Department of Horticulture, says that excessive usage of this road salt can lead to tree death. 

Cregg says protecting trees from salt exposure and selecting salt-tolerant species are the first steps to mitigating this issue. 

Identifying salt damage in trees 

Cregg describes salt damage occurring in two ways: acute damage and chronic damage.

Acute damage refers to when tree trunks, branches, and leaves are exposed to salt. 

“If we think about the white coat of salt that accumulates on our cars this time of year, trees and shrubs adjacent to roadways are experiencing the same thing,” says Cregg

Acute damage is the easiest to identify.

In evergreen trees, such as Michigan White Pines, salt damage causes needle browning and can lead to tree death.

In deciduous trees, such as Oak and Maple trees, salt damage commonly causes “witch’s brooms,” which is when the ends of branches repeatedly die and grow back due to salt exposure, Cregg explains. 

Because chronic injury refers to damage that we can’t see as easily, it can be trickier to identify. Chronic injury occurs when road salt leaches into the surrounding soil and creates high concentrations of sodium and chloride.

Cregg says these high concentrations “reduce the plant’s ability to take up water from the soil solution, resulting in a form of drought stress.”

How to reduce salt damage on trees: protection and selection

Cregg suggests de-icing alternatives, such as beet juice or calcium magnesium acetate, which pose less environmental risk than typical road salt.

While the simple solution seems to be for road commissioners and residents to abandon their usage of road salt, this is an unrealistic approach considering sodium chloride continues to be the most affordable and efficient option for de-icing, and given Michigan’s harsh winters, public safety is often prioritized over environmental concerns. 

Due to this limitation, Cregg emphasizes the importance of creating physical barriers, such as placing burlap wrap or canvas screens around existing trees, to protect them from excessive salt exposure.

These physical barriers would help mitigate damage from the inevitable salt splash caused by cars on the roadway. 

When planting new trees around roadways, it’s important to consider that some tree species are more sensitive to salt exposure than others.

To aid this, Cregg advises homeowners and city planners to select salt-tolerant trees to ensure they can survive in the given environment. 

“Some salt-tolerant trees for our area include Bald Cypress, Kentucky Coffeetree, Japanese Tree Lilac, Dawn Redwood, Horse Chestnut, Hackberry, and Swamp White Oak.”

This story is a part of WDET’s ongoing series, the Detroit Tree Canopy Project.

The Michigan Department of Agriculture and Rural Development may add six new plant species to the state’s list of invasive plants. This list could include Callery pear, Japanese barberry, and two aquatic plants.

If approved, water hyacinth and water lettuce would be considered illegal to sell or transport 30 days after they are officially listed. The Callery pear, common buckthorn, glossy buckthorn, and Japanese barberry would become restricted starting January 1, 2028. These regulations would prevent the sale or purchase of these plants but would not impact property owners who already possess them.

Officials state that these plants can pose risks to Michigan’s environment, economy, and public health. They have the potential to displace native species, damage infrastructure, and in some cases, host ticks that carry diseases.

When a government agency decides whether a chemical in your food is safe, where does the science come from? Most of us assume it’s independent. In the case of Roundup — the world’s most widely used weedkiller — the manufacturer wrote the research, and it went unchallenged for 25 years.

In 2000, a study published in the journal Regulatory Toxicology and Pharmacology concluded Roundup posed no health risk to humans. But internal Monsanto emails released in 2017 litigation revealed company employees had ghostwritten the paper. Despite that, it remained in the scientific record, cited without caveat in hundreds of academic papers and dozens of government documents worldwide.

Harvard historian of science Naomi Oreskes and researcher Alexander Kaurov changed that. Their 2025 analysis found the ghostwritten paper ranked in the top 0.1% of all cited glyphosate literature. They requested the journal retract it. In November 2025, it did, citing “serious ethical concerns.” Oreskes and Kaurov also wrote about their findings in Undark.

The retraction comes as Bayer, which acquired Monsanto in 2018, faces roughly 65,000 Roundup cancer lawsuits. On February 17, the company proposed a $7.25 billion class settlement. The U.S. Supreme Court has agreed to hear a related case this term. Bayer maintains glyphosate is safe.

Oreskes, author of “Merchants of Doubt,” joined Robyn Vincent on The Metro to discuss how one ghostwritten paper shaped pesticide policy for a generation, and what it means now that it’s been thrown out.

How does a global community provide for the needs of its citizens without destroying the planet? That’s the crux of “Anthropause: The Beauty of Degrowth,” a new book out this month.

In the early days of the Covid-19 pandemic, society shut down for a few months. As humans stayed inside, animals returned to their old habitats and pollution eased as industry slowed.

Retired researcher—and new metro Detroit resident—Stan Cox looks at how that “anthropause” could be a preview of the necessary societal changes to save lives and the planet.

He spoke with All Things Considered – Detroit host Russ McNamara last month. Click on the media player to listen or read selected transcripts below.

Russ McNamara, WDET: Why did you write this book?

Stan Cox, Author: The main point I’m making in the book is imagining that we as a society, if we were to rapidly phase out fossil fuels and get by just on the energy that could be generated other ways; and if we stopped plundering the earth for minerals and cutting down forest and causing ecological damage; and we had less energy and materials, and had to allocate them carefully: people know that’s going to mean sacrifice. What am I going to have to give up and so forth?

And what I’m saying in the book is okay, yeah, there are certain things, obviously that will have to be given up. But let’s consider all of the dangers and nuisances, terrible stuff that we put up with an advanced industrial society that has all this energy and materials running through it.

We would be saying goodbye to a lot of those harms and ills by simply not doing a lot of the stuff that requires so much energy input. So the rest of the book, then, is going through specific technologies and activities and so forth that are really harmful to people and the environment, of course, that we would not have the fuel to undertake them, or we would be using resources for meeting people’s basic needs, and we wouldn’t be spending a lot of energy on these other things.

RM: You discuss this and I’m reminded of data centers to run artificial intelligence. People certainly don’t seem to want them and definitely don’t want these in their backyard because there is this concern about the high cost of electricity, and the amount of groundwater that is needed.

SC: That’s absolutely right. One of the big reasons these communities don’t want them is that they create this horrific noise at very high decibel levels and low low frequency noise, which is especially dangerous to human health. When I started writing the book, there wasn’t as much being said about A.I. and the data centers at that time, so I did eventually incorporated them, but the beginning of the second chapter is about noise pollution and and I just used it. It’s seemingly a very small thing, but it really brings out other issues. The leaf blower, especially the gas powered leaf blower, also produces this low frequency and very high volume sound—about eight times the decibel level that the World Health Organization says is safe – and they’re producing a wind about the speed of an EF five tornado. The low frequency sound can travel like three football fields. It’s still above the safe limit.

RM: So what are the societal impacts? Let’s say we start degrowth right now. What are the benefits?

SC: We can’t go on like we’re on the trajectory that we’re on now, because. A degrowth is going to happen. Either a chaotic, brutal degrowth where it’s a Mad Max kind of future, because we’ve tried to force growth to continue and have destroyed ecosystems

Or we can have a planned, rational degrowth that ensures that there’s enough for everybody and that we’re not causing ecological collapse. But there’s no way that growth can continue at this rate.

Sometime in the past three years, we passed a milestone. The quantity of human made stuff—that is everything that human society has manufactured or built or produced—if you weigh all of it up, the mass of all of that exceeds the total mass of all living things on Earth, all plants, animals, microbes, et cetera, and that quantity of stuff being produced is is doubling every 20 years. And clearly that can’t go on.

Herb Stein, an economist from the 70s or 80s was kind of the Yogi Berra of economists. He had a line: “if something can’t go on forever, it won’t” and that’s where growth cannot go on forever. So we have to pull back, create what I called in the book an “anthropause” of our own, and try to have a rational, safe and just reduction in the amount of economic activity for the good of everybody.

Dearborn’s Department of Public Health has been awarded a $101,000 grant to advance firearm safety. The Michigan Department of Health and Human Services funding supports collaborative efforts to educate gun owners on safe handling and storage. 

Dearborn Mayor Abdulllah Hammoud says firearm injury prevention is a public health and safety priority. 

The city’s health department will distribute firearm safety kits, including gun locks, lockboxes, and educational materials.  Dearborn Chief Public Health Officer Ali Abazeed says the grant supports evidence-based education and access to safety tools.

Michigan Chief Medical Executive makes Standing Recommendation regarding children’s vaccines 

Michigan’s Chief Medical Executive, Dr. Natasha Bagdasarian, made a Standing Recommendation to continue issuing vaccinations on schedule based on recommendations by the American Academy of Pediatrics (AAP) and the American Academy of Family Physicians (AAFP). 

Bagdasarian shared that public health experts are not in agreement with new federal vaccine recommendations, prompting the announcement. One of the recent changes was dropping the Hepatitis B vaccine at birth and removing the COVID-19 vaccine recommendation for healthy children and pregnant women. 

Bagdasarian’s Standing Recommendation was made with the Michigan Department of Health and Human Services’ Division of Immunization. 

She says the recommendation does not supersede clinical judgment. She also asks health care providers to make vaccines accessible by removing barriers for patients. 

Bagdasarian says vaccines keep people safe and potentially save lives. 

EGLE renews license for hazardous waste facility 

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has renewed the license for a hazardous waste treatment and storage facility in Detroit for the next 10 years.

Hazardous Waste Management Facility Operating License to EQ Detroit Inc., which does business as US Ecology Detroit South, was issued the license after regulatory review and a public comment process. Several people strongly opposed the facility because it emits strong odors leading to health concerns like asthma. The facility also has a history of clean air violations. 

EGLE renewed the license, adding new requirements, such as expanding air and groundwater monitoring. The facility must replace six tanks beginning in January 2026 and install odor control equipment by the end of Dec 2027.

Tunnel in southwest Detroit 

The Great Lakes Water Authority has started building a sewage relief system near the Rouge River in Southwest Detroit. Crews will spend at least two years digging a tunnel to carry excess stormwater to an underused retention and treatment center. Chief Operating Officer Navid Mehram says the $87 million project should reduce the risk of flooding and sewage backups during heavy rain. 

“So this is an example where we’re making an investment in our existing system by rerouting some flows, so that we can leverage an existing facility that wasn’t receiving all the flow it can treat.”

Mehram says the project will not increase customers’ sewage bills. He says state and federal funding will help pay for the tunnel. 

New tech firm in town 

Detroit is getting a new high-tech security and AI solution firm, Eccalon. The defense tech company will create 800 new jobs ranging from $25-100 per hour. 

The facility will have manufacturing operations, training programs and an innovation center. 

The company’s headquarters is moving from Maryland to become a part of the tech innovation in Detroit. Eccalon will be located at the Bedrock-owned Icon building at 200 Walker Street. 

Eccalon Chairman and CEO André Gudger says the new headquarters will develop cybersecurity and advanced manufacturing and automation. 

The company hopes to open early next year.
