Which of the following types of toxic agents primarily affect the central nervous system?

Neurotoxins are the type of toxic agents that primarily affect the central nervous system (CNS). These substances can interfere with the normal functioning of neurons, leading to a range of neurological symptoms such as weakness, tremors, and in severe cases, paralysis or death. Neurotoxins may disrupt the transmission of signals in the brain and spinal cord, impacting processes such as motor control, sensory perception, and cognitive function.

In contrast, nephrotoxins primarily target the kidneys, causing damage that can lead to renal failure. Hemotoxins affect the blood and can cause issues like anemia or disrupt clotting mechanisms. Dermatoxins specifically impact the skin and can lead to irritations or other dermal conditions. Understanding the distinct effects of these toxic agents is crucial for emergency responders and HAZWOPER-trained personnel, as it informs the appropriate medical response and treatment for exposure incidents.
