School children in San Joaquin Valley in California, US are periodically exposed to pesticides while at stops or on school buses. Three incidents in the last seven months have raised concern in authorities.
Nancy and Bryan Lara, ages 10 and 8, for instance, saw a tractor surrounded by white clouds near their school bus stop in Caruthers on May 14. The children hid behind a row of grapevines, but they could taste the noxious blend of liquid sulfur, gibberellic acid, insecticide and fertilizer as the rig rolled past them, billowing out its chemical cargo.
Moments earlier, the mist had enveloped 17-year-old Carina at another stop about two blocks away.
"I felt it. It was wet. I was wet," said Carina, who asked that her last name not be used.
School bus driver Crystal Wells drove up in time to see Nancy and Bryan running for cover. She pulled her bus to the side of the road to avoid exposure. Her decision kept 50 children from being exposed.
The bus driver picked up the three children, called her supervisor and drove them to Caruthers High School, where they were met by firefighters, medics and investigators. Soon, the three began to suffer headaches, nausea, itchiness and breathing difficulties.
Erika Lara arrived to find her two children hooked up to oxygen.
"I cried because they had oxygen on," Lara said. "I wasn't expecting that."
