Which of the following describes chloramines?

Chloramines are compounds that are formed when chlorine reacts with organic substances in the water, particularly nitrogen-containing compounds like those found in swimmer waste, urine, skin cells, and other contaminants. Option C accurately describes chloramines, as they are known to cause eye and skin irritation, which is a common concern in swimming pools where chlorine levels may be improperly managed.

Additionally, chloramines are often responsible for the strong chemical smell associated with pools. This could be misleading, as they typically give off an unpleasant odor rather than a pleasant one. They also do not function effectively as disinfectants compared to free chlorine, which is the active form of chlorine used in pools. Their efficacy as disinfectants is lower, not higher, than that of chlorine. Understanding these characteristics is crucial for maintaining proper water quality in swimming pools and ensuring the comfort and safety of users.
