👉 Cassette fumes refer to the odorless, invisible pollutants released from audio cassettes during use, primarily due to the degradation of plastic and magnetic materials. These fumes are a mix of volatile organic compounds (VOCs), including acetone, formaldehyde, and phthalates, which can be harmful when inhaled over prolonged periods. They often manifest as a pungent, chemical smell, resembling nail polish remover or burning rubber. While the concentrations are generally low, they can be particularly problematic in enclosed spaces like homes with multiple cassettes, leading to potential respiratory issues and discomfort. Proper disposal and using ventilation can help mitigate these fumes.
