Skin irritation from UV radiation is an example of which type of effect?

Skin irritation from UV radiation is classified as a local effect because it specifically targets the area of the skin directly exposed to the radiation. Local effects are characterized by their impact being confined to the site of exposure without spreading to other areas of the body. In this case, UV radiation causes inflammation, redness, and other irritations where it hits the skin, making the response localized rather than systemic.

Systemic effects, on the other hand, refer to conditions that affect the entire body or multiple organ systems following exposure. These types of effects often occur after a substance enters the bloodstream or affects internal systems, which is not the case with skin irritation due to UV exposure. This distinction is crucial for understanding how different types of exposures lead to varying health concerns and the necessary precautions that should be taken in environments where such hazards are present.
