Vineyard sprayer’s lung is seen in which metal poisoning
**Core Concept**
Vineyard sprayer's lung is a type of occupational lung disease caused by the inhalation of metal particles, specifically chromium and manganese fumes. This condition is characterized by the formation of granulomatous lesions in the lungs, leading to inflammation and fibrosis.
**Why the Correct Answer is Right**
The correct answer is related to the inhalation of chromium fumes, which is a common occupational hazard in vineyard spraying. The chromium fumes react with moisture in the lungs to form chromic acid, leading to an inflammatory response and the development of granulomatous lesions. This condition is often seen in workers who use chromated copper arsenate (CCA) to spray vineyards. The inhalation of manganese fumes is also a known cause of occupational lung disease, but it is not directly related to vineyard sprayer's lung.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because arsenic poisoning is not directly related to vineyard sprayer's lung, although arsenic is a component of CCA.
* **Option B:** This option is incorrect because lead poisoning is a separate occupational hazard that affects the nervous system and kidneys, not the lungs.
* **Option C:** This option is incorrect because cadmium poisoning is a separate occupational hazard that affects the kidneys and bones, not the lungs.
**Clinical Pearl / High-Yield Fact**
Vineyard sprayer's lung is a classic example of a work-related lung disease, and its prevention is crucial in occupational health. Workers handling chromated copper arsenate should wear protective gear, including masks and gloves, to minimize exposure to chromium fumes.
**Correct Answer:** D.
