Toxic waste refers to any discarded material that can cause harm to human health or the environment. This type of waste can come from various sources, including industrial processes, chemical manufacturing, and even household products. Common examples include heavy metals, pesticides, and certain medical waste. Proper disposal and management of toxic waste are crucial to prevent contamination of soil, water, and air. The handling of toxic waste is regulated by laws and guidelines to ensure safety. Organizations like the Environmental Protection Agency (EPA) in the United States set standards for the treatment and disposal of these materials. Failure to manage toxic waste properly can lead to serious environmental and health issues.
