Stark Warning: Dangerous Levels Of Toxic Gas Detected In Louisiana’s “Cancer Alley”
Toxic gas used in petrochemical manufacturing has been detected at levels a thousand times higher than what is considered safe in Louisiana.
The chemical in question is ethylene oxide, an extremely flammable and colorless gas with a slightly sweet smell. It has a variety of industrial uses, including the production of products like antifreeze, detergents, fibers, and bottles. It’s also used to sterilize medical and food production equipment.
Researchers at Johns Hopkins University recently tested levels of ethylene oxide in the air of southeastern Louisianna using two vans fitted with different but highly sensitive technologies to measure the gas in real-time.
This part of the state includes “Cancer Alley,” a stretch along the Mississippi River between New Orleans and Baton Rouge that has very high rates of cancer and other health issues among its residents. By coincidence, it also has a significant number of petrochemical plants that pump out all kinds of industrial chemicals, including ethylene oxide.
Long-term exposure to concentrations of ethylene oxide over 11 parts per trillion is considered problematic to human health due to its ability to directly damage DNA and increase the risk of cancer.
Shockingly, this study found levels as high as 40 parts per billion in areas close to industrial facilities. The concentrations were also found to be way higher than the estimates created by the Environmental Protection Agency.

“We expected to see ethylene oxide in this area. But we didn’t expect the levels that we saw, and they certainly were much, much higher than EPA’s estimated levels,” Peter DeCarlo, senior author and an associate professor of Environmental Health and Engineering at Johns Hopkins University, said in a statement.
“We’d drive through the industrial areas and saw concentrations hitting 40 parts per billion, which is more a thousand times higher than the accepted risk for lifetime exposure,” DeCarlo said.
The researchers warned that people living near facilities that manufacture and use ethylene oxide could be at a higher risk of cancer.
“Our findings have really important implications for community residents, especially infants and children. Ethylene oxide has been shown to directly damage DNA, meaning that exposures that occur in early life are more dangerous,” said Keeve Nachman, associate professor of Environmental Health and Engineering and the co-director of the Risk Sciences and Public Policy Institute.
The new study was published in the journal Environmental Science & Technology.

Louisiana’s disappearing coast could shape Baton Rouge’s future
BATON ROUGE, La. (WAFB) – South Louisiana’s coast has long served as a natural buffer between communities and rising water.
But since the 1930s, Louisiana has lost nearly 2,000 square miles of coastal land.
Dr. Torbjorn Tornqvist, a professor at Tulane University, said Louisiana is one of the most vulnerable coastal areas in the world because of climate change, sea level rise and subsidence.
“Louisiana is arguably one of the most vulnerable… perhaps the most vulnerable coastal zones in the world when it comes to climate change and sea level rise… and there are several reasons for that but one important reason is that we have high subsidence rates, and that means sea level rise here is a lot faster than the average around the world,” Tornqvist said.
Tornqvist is the lead author of a recently published study examining the long-term impacts of sea level rise across south Louisiana.
He said the issue is no longer limited to communities closest to the Gulf Coast.
“People are leaving the coast of Louisiana, but it’s going to accelerate over the course of the century. And those people are going to have to go somewhere, and it’s likely that a significant number are going to look at a place like Baton Rouge to move to,” Tornqvist said.
Since Hurricane Katrina, Louisiana has invested billions of dollars in large-scale restoration projects designed to reduce flood risk and strengthen the coast.
Some researchers believe those projects are important but not permanent fixes.
“We have…right now we have a pretty high-quality flood protection system that’s obviously way better than it was during Katrina and we should certainly keep investing in upkeep, but we also have to recognize that’s only going to take us so far,” Tornqvist said.
State officials say those investments remain critical as Louisiana adapts to future flood risks.
Micheal Hare, executive director of the Coastal Protection and Restoration Authority, said the state’s coastal plan is designed to balance restoration work with protection projects, including levees.
“Our 2023 master plan certainly incorporates the best science available to us to then come up with a balanced approach between how do we effectively spend money on restoration as well as money on protection projects like levees,” Hare said.
Hare said those projects will continue to evolve as future risks change. CPRA and the Army Corps of Engineers are re-evaluating portions of the West Bank and Vicinity levee system in New Orleans to meet projected future flood risks within the next half-decade.
“Morganza to the Gulf is a great example, location communities came together, they started funding it…so that protection is critical…It will constantly be maintained and constantly elevated to meet the new levels of threats and risks that are out there,” Hare said.
Coastal officials and researchers agree that what happens along Louisiana’s coast will continue to affect communities far beyond the shoreline for generations.
“And so maybe you don’t live behind the levee, but I promise you want those coastal communities to stay there and to keep working, and to stay productive and engaged…so that we don’t have to have these flood fights further north or lose parts of our economy,” Hare said.
Tornqvist said the decisions made now could shape the future of Louisiana communities.
“What’s really important to recognize is that the next few decades are basically going to decide the long-term future of cities like Baton Rouge,” Tornqvist said.
Louisiana has always lived with water. As the coast changes and sea levels rise, the challenge is how communities across south Louisiana continue adapting for generations to come.
From the Gulf Coast to Baton Rouge, the future of Louisiana’s coastline is a conversation that impacts the entire state.

Louisiana is the eighth most affordable state to retire, study says
Louisiana ranks among the top 10 most affordable states to retire, according to a new study from Retirement Living, a national journal of retirement research.
Researchers analyzed each state’s housing costs, living expenses and tax friendliness to compile the ranking. Louisiana, they say, is the eighth most affordable state for retirees.
In Louisiana, the median monthly rent for a one-bedroom apartment is $932, the median home sale price is $255,000, monthly grocery spend per capita is $272, the average price per gallon of regular gas is $4, the average Medicare Advantage monthly premium is $13.35 and the average effective property tax rate is 0.55%.
West Virginia is the most affordable state to retire, followed by Mississippi, Alabama, Oklahoma, Arkansas, Kentucky, Missouri, Louisiana, Indiana and Kansas. Researchers describe the South as “the sweet spot for an affordable retirement.”
The most expensive state to retire, meanwhile, is California, followed by Hawaii, Washington, Oregon, Colorado, New Jersey, Massachusetts, Utah, New York and Minnesota.

Louisiana agencies urge hurricane preparation ahead of season start
BATON ROUGE, La. (WAFB) – With hurricane season approaching, the Louisiana Coastal Protection and Restoration Authority is bringing the community together to prepare before a storm forms.
“We can’t stop disasters from happening. We can’t stop hurricanes from happening. But what we can do is equip our communities with the resources that they need to prepare for these storms ahead of time,” said Jayda Morris, CPRA outreach manager.
The agency hosted an event featuring interactive storm simulations and a full model of the Mississippi River.
“If you do it now, like on a sunny day like today, you’re ready to go for the rest of the season,” Jay Grymes said.
El Niño may reduce storms, but Louisiana still at risk
State Climatologist Jay Grymes said an El Niño pattern may reduce the number of storms in the Atlantic but warned against a false sense of security.
“In those 25 years, Louisiana, some part of the state has been impacted by 29 storms. That’s one a year, regardless of El Niño. So that should tell you something,” Grymes said.
He said the bigger concern is storms that can form in the Gulf with little warning.
“If we’re going to get a storm, it very possibly could be one that bubbles up in the Gulf and doesn’t give us five or seven days to track it coming our way. It gives us 40 hours to get ready for a landfall. So it’s imperative that you go ahead and do it now,” Grymes said.
Preparation goes beyond stocking water
Preparing now includes walking through yards, checking trees, and knowing whether everyone in the family can survive two weeks without power.
PhD students with the LSU College of the Coast and Environment gave the community a virtual reality experience that puts users inside a storm.
“If they wear the goggles or play with the Apple Vision Pro, they can understand how high will the flood be, and they can know how dangerous is the hurricane scenario,” said Yixuan Wang.
The VR simulation uses real historical data to show users what compound flooding looks like in New Orleans and surrounding areas. The goal is to make the science real for people who can’t picture what a flood map means.
“It’s just to let you understand the environment. We will add the audios, the different sound of the wind and the storm. And you can see how tense of the rainfall around you,” Wang said.
Organizers said the event is about making sure that when a storm threatens the area, families already know their plan.
Information from the event is available on CPRA’s website. Hurricane season runs through Nov. 30.
