COVID disinfectants raise safety concerns among scientists.

Scientists warn that the increased use of quaternary ammonium compounds (QACs) in disinfectants during the COVID-19 pandemic is linked to health problems, antimicrobial resistance, and environmental harm. QACs are found in disinfectant solutions, wipes, hand sanitizers, sprays, and foggers, and are also being incorporated into personal care products, textiles, paints, medical instruments, and more. The scientists recommend eliminating unnecessary uses of QACs and requiring full disclosure of QACs in all products to reduce health hazards and environmental harm.
