Summary

This study looked at 629 children in California to see if exposure to pesticides at home or from nearby farms is linked to childhood leukemia. Researchers collected dust from carpets and vacuum cleaners and mapped crops near homes. The goal was to measure chemical levels and see if they relate to leukemia risk.
