Earlier this month, Durham Housing Authority executive director Anthony Scott confirmed the presence of yet another toxic substance inhabiting McDougald Terrace. Joining the likes of carbon monoxideโ€”which led the DHA to evacuate 280 families to area hotels in Januaryโ€”lead, mold, and sewage problems, the cityโ€™s oldest and largest public housing complex also had asbestos. (The first six families returned to McDougald on Friday.)

Here, we take a look at what science says about the conditions and potential hazards theyโ€™ve been living with for, well, who knows how longโ€”and what happens when indifferent officials at all levels of government allow these complexes to fall into disrepair.   


Carbon Monoxide Poisoning

Caused by: Incorrectly installed or poorly ventilated household appliances, which emit CO. 

Leads to: Headache, dizziness, weakness, upset stomach, vomiting, chest pain, confusion, flu-like symptoms; loss of consciousness or death at high levels; those sleeping or drunk may die before experiencing symptoms. More than 400 Americans die each year from accidental CO poisoning.


Mold Exposure

Caused by: Damp and moldy environments.

Leads to: Stuffy nose, wheezing, upper respiratory infections, red or itchy eyes or skin; more intense reactions for those with allergies or asthma; potential link to asthma in some children; hypersensitivity pneumonitis for those susceptible; sometimes no effects.   


Sewage Issues

Caused by: At McDougald Terrace, a corrupted manhole leaking raw sewage and a stormwater pipe that has reportedly been leaking raw sewage into Rocky Creek since 2017. Residents have also long reported backed-up toilets.

Leads to: Gastroenteritis, with symptoms including nausea, vomiting, abdominal pain, diarrhea, cramps, fever, and dehydration; exposure in homes has been linked to hepatitis A.


Lead Poisoning

Caused by: Lead-based paint and lead-contaminated dust common in older buildings. Lead builds up in body over months or years.

Leads to: Fatal at high levels. In children, causes learning difficulties, irritability, loss of appetite; in adults, high blood pressure, mood disorders, miscarriage, stillbirth, premature birth; childhood exposure linked to violence in young adulthood in some studies. 


Violent Crime

Caused by: Lots of things, including exposure to violent crime; also, possibly, lead. 

Leads to: Childhood trauma, destabilization, trouble sleeping, PTSD, desensitization to violence, myriad behavioral, psychological, and physical issues, academic failure, alcohol and drug abuse, adult criminality, early death by violent crime. 


Cockroaches/Bedbugs

Caused by: Evolution.

Leads to: Cockroaches: allergic reactions and asthma symptoms; spread bacteria, parasitic worms, and other pathogens. Bedbugs: sometimes severe allergic reactions; secondary skin infections. Both: mental health issues including anxiety and insomnia.


Asbestos Exposure

Caused by: Dust from a group of naturally occurring minerals with soft, wooly fibers resistant to heat, electricity, and corrosion, sometimes used in drywall and cement. 

Leads to: Cancers of the lung, larynx, ovary, as well as mesothelioma, a rare, aggressive, and fatal tumor. Worst effects stem from intense concentrations or regular exposure over a long period of time.
