Which chemical is known to cause throat issues and vision problems?

Ammonia is recognized for its potential to cause throat irritation and vision problems, primarily because it can be a respiratory irritant and can affect mucous membranes upon exposure. When inhaled, ammonia gas can lead to symptoms such as coughing, throat irritation, and in higher concentrations, it may cause more severe respiratory issues. Additionally, exposure to ammonia can result in eye irritation and damage, leading to vision problems. This is particularly relevant in agricultural settings where ammonia is commonly used as a fertilizer or emitted from animal waste.

While chlorine, carbon dioxide, and hydrogen sulfide can also pose health risks, they are associated with different symptoms or mechanisms of action. Chlorine can irritate the respiratory system and eyes but is primarily known for its effects in water treatment and potential to cause injury in high concentrations. Carbon dioxide, while harmful at very high levels, primarily leads to suffocation rather than throat and vision issues. Hydrogen sulfide is known for causing respiratory irritation as well, but its primary effects are more toxic and related to rapid loss of consciousness rather than persistent throat and vision problems. Thus, ammonia stands out specifically for the throat issues and vision problems associated with its exposure.
