In a first-of-its-kind study, UCLA’s Sustainable and Technology Policy Program (STPP) looked at real-world applications of three fumigant pesticides applied in California. They found that these pesticides are routinely applied in the same area, either together or one right after the other, and that exposure to any two of these pesticides in combination can increase cancer risk by more than just their sum. State regulators do not account for this added risk and must act swiftly to protect the most vulnerable and most impacted—including more than half a million California schoolchildren.
