Which statement best describes local effects?

• A. They affect the entire body
• B. They involve organs distant from contact point
• C. They are not caused by contact with skin or eyes
• D. They are injuries that occur at the contact site with skin, eyes, or respiratory tract

Answer: (D)

Local effects are injuries that happen right at the point of contact with the body. They occur where the chemical touches the skin, eyes, or the respiratory tract, causing irritation or damage at that site. For example, a splash on the skin can cause redness or rash; contact with the eyes can cause burning and tearing; inhaling fumes can irritate the nose or throat at the point of entry. This is different from systemic effects, which occur after the substance is absorbed and travels through the bloodstream to affect distant organs. Therefore, the description best matching local effects is injuries that occur at the contact site with skin, eyes, or respiratory tract.
