Nanomaterials, which are materials with a size of less than 100 nanometers, have unique properties that make them useful in various applications, including electronics, pharmaceuticals, and environmental remediation. However, recent research has raised concerns about their potential health and environmental risks. Nanomaterials can easily enter the human body and cause harm, and their use is largely unregulated in the US. Studies have shown that nanomaterials can cause respiratory problems, oxidative stress, and DNA damage, among other health effects.
The European Union has taken steps to regulate nanomaterials, including introducing new regulations on their use in cosmetics. In contrast, the US FDA has a limited approach to regulating nanomaterials, and companies are not required to label products that contain them. Consumers can take action by contacting their elected representatives to support stronger regulations and labeling requirements. Until comprehensive safety testing and regulatory frameworks are in place, consumers must be vigilant and advocate for caution when it comes to the use of nanomaterials. The precautionary principle, which prioritizes caution when there is scientific uncertainty about potential harm, is essential in this area.
