What are the two broad categories of chemical agents that can cause worker's lung?

Worker's lung refers to a group of respiratory diseases that result from exposure to various harmful chemical agents in the workplace. Among these, isocyanates and anhydrides are significant culprits.

Isocyanates are reactive chemicals commonly found in materials such as polyurethane foams, paints, and adhesives, leading to respiratory issues, including occupational asthma and hypersensitivity pneumonitis. They are known for their ability to cause inflammation in the airways upon inhalation.

Anhydrides, such as phthalic anhydride and maleic anhydride, are also associated with similar respiratory problems. They are used in various industrial processes and can result in lung damage and allergic reactions when inhaled.

The combination of isocyanates and anhydrides as a category highlights the importance of recognizing these specific agents in the context of occupational lung disease. Their potential to cause serious health issues underlines the necessity for proper safety measures and monitoring in environments where exposure can occur. Other options do list important agents, but they do not accurately represent the two broad categories seen in the context of worker’s lung as specifically as isocyanates and anhydrides do.
