Which of the following statements about Penta's acute toxic effects is true?

The statement that Penta can lead to respiratory distress is true because exposure to Penta, or pentachlorophenol, can affect various bodily systems, including the respiratory system. Inhalation of Penta can cause irritation of the respiratory tract, potentially leading to symptoms like coughing, difficulty breathing, and other forms of respiratory distress.

Understanding Penta's toxicological profile is essential for those handling this chemical. Recognizing that it can impact the respiratory system is crucial for implementing appropriate safety measures, including the use of protective equipment and ensuring proper ventilation in work areas.

Other statements do not accurately reflect the potential health impacts of Penta. For instance, while dermal exposure can lead to adverse effects, it is not the exclusive route of exposure. Furthermore, Penta can indeed affect the eyes, causing irritation and possible long-term damage upon contact. Lastly, there is no evidence to support that Penta improves overall health; instead, it poses various health risks, which necessitate careful handling and exposure prevention.
