Mold spores are not classified as hazardous waste under CERCLA. While they can pose health risks, the act focuses on significant environmental contaminants that pose risks to human health and the ecosystem, such as chemicals and waste products, rather than biological agents like mold.

Electromagnetic fields (EMFs) are not considered hazardous waste and do not fall under the purview of CERCLA. EMFs are associated with electrical devices and infrastructure but lack the chemical toxicity and environmental hazards that CERCLA addresses, focusing instead on physical phenomena rather than waste cleanup.

While radon is a naturally occurring radioactive gas that can pose health risks, it is not classified as hazardous waste under CERCLA. The act primarily targets waste produced by human activities that lead to contamination, rather than naturally occurring substances, which are often managed through other regulatory frameworks.
