The COVID-19 pandemic has led to a surge in the use of antimicrobial chemicals known as quaternary ammonium compounds , which are linked to health issues, antimicrobial resistance, and environmental harm, according to a critical review by over two dozen scientists in the journal. QACs are found in disinfectant wipes, hand sanitizers, and other products, and their overuse has been found to be unnecessary or even harmful in many cases.
QACs are increasingly used in disinfectant solutions, wipes, hand sanitizers, sprays, and foggers, and are also being incorporated into personal care products, textiles, paints, medical instruments, and more. Since the pandemic, levels of these chemicals in the environment and our bodies have increased in parallel.
The scientists recommend eliminating uses of QACs that are either unnecessary or where their effectiveness has not been demonstrated. For example, disinfection with QACs often has no benefit over cleaning with plain soap and water. Other recommendations include requiring full disclosure of QACs in all products and closely monitoring their levels in people and the environment.
