What is a common symptom of toxic exposure via inhalation?

Respiratory distress is a common symptom of toxic exposure via inhalation because inhaling toxic substances directly affects the respiratory system. When harmful chemicals enter the lungs, they can cause immediate reactions such as difficulty breathing, wheezing, coughing, and even more severe complications depending on the nature and concentration of the toxin. These respiratory issues arise because the airways may become inflamed, obstructed, or damaged, leading to reduced oxygen exchange and overall respiratory function.

Inhalation exposure is particularly concerning because it allows toxins to bypass the body's natural barriers and enter the bloodstream rapidly, increasing the risk of systemic effects. While dizziness, headaches, skin irritation, and nausea can also occur due to various forms of chemical exposure, they are not as directly correlated with inhalation as respiratory distress is. Thus, respiratory distress stands out as the most relevant symptom when considering toxic exposure through breathing in harmful substances.
