De-pollutes refers to the act of removing pollutants from a particular environment or substance. Thus, its antonyms refer to actions or processes that contribute to the contamination rather than cleaning. Common antonyms for de-pollutes include pollutes, contaminates, defiles, befoul, fouls, and taints. For instance, pollutants can affect the air, water, or land leading to contamination of the environment. Negative human actions such as dumping waste, using harmful chemicals or destroying natural habitats contribute to the pollution of various ecosystems.
