Overview

• First nationwide study links truck traffic from warehouses to a 20% rise in nitrogen dioxide pollution.
• Communities near warehouses, especially those with higher minority populations, face greater health risks.
• Newer warehouses, built since 2010, are larger and attract more heavy-duty vehicle traffic.
• Top 10 counties with the highest concentration of warehouses include Los Angeles, Harris, and Miami-Dade.
• Researchers call for stricter regulations and zero-emission vehicle adoption to mitigate pollution.
