Concerns arise over indoor air pollution from metal nanoparticles in cleaning agents

Recent research suggests that nanoparticles present in common household cleaning agents could pose a significant source of indoor air pollution, potentially elevating the risk of cancer. Nanomaterials found in cleaners and sprays, including silver, copper, and zinc, have the capacity to resettling and become airborne long after their initial application.

An air-controlled chamber experiment conducted as part of the study demonstrated high rates of particle resuspension, particularly in carpeted areas. Children are especially susceptible due to the higher concentrations of particles at lower heights and their frequent contact with floors.

The study also revealed that when an adult walks in a room and steps on these deposited particles, they become resuspended in the air, rising as high as the person's breathing zone.

While consumers often scrutinize cleaning product labels for harmful chemicals, a lesser-known concern revolves around the presence of metal nanoparticles. These tiny particles, increasingly incorporated into various products for their antimicrobial properties and cleaning efficacy, possess the ability to easily become airborne, potentially contributing to indoor air pollution. Exposure to indoor air pollutants such as particulate matter, nitrogen dioxide, and certain heavy metals has been linked to child obesity.
