Fire crews treated 17 children and 9 adults at Cudahy and South Los Angeles elementary schools after a fuel dump by an aircraft, according to the Los Angeles County Fire Department.
Numerous children were reporting skin irritation and a noxious smell at the schools Tuesday shortly after noon.
Crews responded to 93rd Street Elementary and Park Avenue Elementary.
No one was transported to a hospital and no evacuation orders were issued for the surrounding areas.
A Delta Airlines flight had to return to Los Angeles International Airport shortly after takeoff and was dumping fuel on its return.
