Overview
- Dozens of firefighters worked to contain a large tire-and-debris blaze near Kellogg and Lawndale that burned on Monday and produced thick black smoke over Southeast Houston.
- Community-installed monitors run by Air Alliance Houston detected PM2.5 spikes of about 85–98 micrograms per cubic meter in Denver Harbor and Kashmere Gardens roughly four miles downwind, above the EPA 24-hour standard of 35 μg/m3.
- City and state agencies said their official readings did not show levels they considered a public-health alarm, while the Houston Fire Chief advised people with respiratory conditions to limit outdoor exposure.
- Residents and advocates stressed that few or no official monitors sit in the East End, pointed to Mammoth Metal Recycling’s prior fires and citations, and urged regulatory review and expanded monitoring because the facility may lack required permits.
- Public-health experts note tire fires release fine particles, volatile chemicals and metals that can worsen asthma and raise longer-term heart and lung risks, so parents are watching for throat irritation, persistent cough and worsened breathing and seeking possible follow-up testing and government action.
