Irritation to the eyes, nose, and throat, and upper respiratory infections such as bronchitis and pneumonia are examples of what?

• A. Short-term effects
• B. Long-term effects
• C. Acute health effects
• D. Chronic health effects

Answer: (A)

When people are exposed to airborne irritants, the health effects that show up soon after that exposure and don’t linger are short-term responses. Eyes, nose, and throat irritation are classic immediate reactions to irritants like dust, fumes, or smoke. Upper respiratory infections such as bronchitis and pneumonia can also develop in the near term after exposure to harmful agents, and they typically resolve or improve with time or removal of the irritant. This time frame distinguishes them from long-term or chronic effects, which arise from sustained or repeated exposure and persist for months or years, such as chronic bronchitis or long-lasting respiratory damage. So the scenario describes effects that appear quickly and are not necessarily permanent, which is why short-term effects is the best fit.
