Final answer:

Untreated sewage in water bodies primarily introduces nutrients like nitrogen and phosphorus, pathogenic microorganisms, and oxygen-demanding waste, leading to environmental issues such as algal blooms, eutrophication, and hypoxia.


Explanation:

Untreated sewage does not typically contain toxic heavy metals as a major pollutant; instead, it primarily introduces nutrients like nitrogen and phosphorus, pathogenic microorganisms, and oxygen-demanding waste into water bodies. These nutrients from sewage can lead to issues like algal blooms, eutrophication, and hypoxia, impacting aquatic ecosystems negatively.
