WATCH: Enduring the “endless” expansion of the nation’s petrochemical corridor

As mounds of dredged material from the Houston Ship Channel dot their neighborhoods, residents are left without answers as to what dangers could be lurking.

In the course of a century, Houston, once known for its magnolia flowers, turned into the “energy capital of the world.” To many, at 52 miles long and deepening under its 11th expansion, the Houston Ship Channel represents its epicenter.

The channel hosts hundreds of chemical facilities, some of which have years of documented Clean Air Act violations. Amnesty International called the channel a “sacrifice zone” where fenceline communities, made up predominantly with people of color, are disproportionately exposed to pollution. This is seen as the “cost of doing business,” according to the report.

But to people like Juan Flores and his family, the area is also home.

Flores, who you’ll meet in the video report above, has lived in Galena Park his entire life, and has been surrounded by the Houston Ship Channel’s dredge material deposit sites for as long as he can remember. He even recalls playing in them as a child.

The current 11th expansion of the port will create new dredge deposit sites and will stack new dredge material on old sites. In response to communities’ concerns of potential risks, Port Houston, the local entity that manages the public ports of the channel and is in charge of the expansion alongside the U.S. Army Corps of Engineers, has said there is no cause for concern. According to the Corps, the material is tested before being placed on the mounds — yet the Corps has stated in the past that they do not test the deposit sites.

Watch the video above to learn more about the stories of these communities and their industrial neighbors.

Editor’s note: This story is part of a two- part series that will highlight the expansion of industry along the Houston Ship Channel – and the channel itself – amidst the landscape of an ever growing industrial footprint and the pollution that comes with it.

Increased autism risk linked to exposure to wildfire smoke during pregnancy

In a first-of-its-kind study published in Environmental Science and Technology, researchers found that mothers who were exposed to wildlife smoke during the third trimester of pregnancy were more likely to have children diagnosed with autism by age 5.


In short:

  • More frequent exposure to wildlife smoke during pregnancy was associated with a higher risk of autism in children.
  • The study analyzed more than 200,000 mother-child pairs in Southern California between 2006 to 2014; nearly 60% of them were exposed to wildfire smoke for more than 5 days during pregnancy.
  • The authors also found that prenatal exposure to particulate matter air pollution from a variety of sources — not just wildfires — is associated with an increased risk of autism in children.


Key quote:

“As climate change increases the frequency and intensity of wildfires in many parts of the world, understanding their relationship with autism is important to being able to develop preventive policy and interventions that will protect pregnant women and their children.”

Why this matters:

As climate change continues to impact global weather patterns, wildfires have become increasingly intense and frequent. Their impact on air pollution is significant - in California, wildfires account for over 70% of the fine particulate matter exposure on days with poor air quality. Environmental hazards that affect the health of pregnant people and their children can have long-term and severe outcomes. The authors of this study underscore the need for policies that protect vulnerable populations from air pollution and reduce the inequality in its health impacts.
