Scientists raise concerns about popular COVID disinfectants EnvSciTech
The COVID-19 pandemic has boosted the unnecessary use of antimicrobial chemicals linked to health problems, antimicrobial resistance, and environmental harm, warn more than two dozen scientists inTheir critical review details how quaternary ammonium compounds are increasingly marketed and used in home, health care, education, and workplace settings despite the availability of safer alternatives and in some cases limited evidence of reduced disease transmission.
Human studies have found associations between QACs and asthma, dermatitis, and inflammation. Laboratory animal studies also raise concerns about potential links to infertility, birth defects, and more. Further, there has been evidence dating back to the 1950s that QACs contribute to, making certain bacteria species resistant both to QACs themselves and to critical antibiotics.
QACs are increasingly used in disinfectant solutions, wipes, hand sanitizers, sprays, and foggers, and are also being incorporated into, textiles, paints, medical instruments, and more. Since the pandemic, levels of these chemicals in the environment and our bodies have increased in parallel.
