Final answer:
The proper disposal method for urine and feces after chemotherapy is using a biohazard container, not flushing down the toilet or disposing of in regular trash, to avoid environmental pollution and health risks.
Step-by-step explanation:
The proper disposal of urine and feces after chemotherapy treatment is a critical health issue. Due to the potential presence of pharmaceutical residues in the excreta of patients undergoing treatment, normal disposal methods such as flushing them down the toilet may not be appropriate as they can contribute to environmental pollution. Instead, one should follow specific biosafety procedures designed to manage biohazard waste. All materials that fall under the category of biohazard waste must be appropriately sterilized by autoclave before being disposed of, in order to prevent any contamination risk.
Therefore, for someone who has undergone chemotherapy treatment, urine and feces should be disposed of following medical and healthcare regulations. Typically, this involves using a biohazard container designed for such waste, which is then treated according to healthcare facility procedures. Flushing chemotherapeutic waste down the toilet or disposing of it in regular trash could lead to environmental pollution as well as pose a risk to public health.
