Benzene can cause skin irritations and overstimulation of which body system?

Benzene is a well-known solvent and chemical used in various industrial applications. It is recognized for its potential to cause significant health issues, especially through dermal exposure and inhalation. When it comes to skin irritations, benzene can penetrate the skin and lead to irritation or dermatitis.

The overstimulation of the nervous system is particularly notable with benzene exposure. Symptoms may include headaches, dizziness, confusion, and even more severe central nervous system effects, particularly with high levels of exposure. This over-stimulation occurs due to benzene's ability to affect neurotransmitter release and neuronal excitability, leading to neurologic symptoms.

In comparison, while the respiratory system is indeed affected by inhaling benzene, the primary concern is not "overstimulation" but rather respiratory issues like irritation of the mucous membranes or lung damage in severe cases. The circulatory and digestive systems are not primarily associated with the acute effects of benzene exposure in the same manner as the nervous system.

Therefore, the correct answer centers on the impact benzene has on the nervous system, particularly concerning stimulation and the range of symptoms that may arise from such exposure.
